The peach fruit fly, Bactrocera zonata Saunders, is one of the most economically important Tephritidae species that attack several host plants and causes serious damage in Asia and Africa. Currently, B. zonata is absent from many countries and regions but has a risk of invasion. Therefore, it is crucial to investigate the impact of climate change on the global potential distribution of B. zonata . In this study, we used MaxEnt and CLIMEX models to estimate the risk area for B. zonata under near current and future climate conditions. The MaxEnt and CLIMEX results showed that the south of North and Central America was suitable for B. zonata . The European countries were slightly suitable for B. zonata . In Asia, the highly suitable regions of B. zonata included Saudi Arabia, United Arab Emirates, Oman, Iran, Pakistan, India, Nepal, Bangladesh, Bhutan, Myanmar, Thailand, Vietnam, and Laos. Moreover, China, Philippines, Indonesia, and Japan showed highly climate suitability for B. zonata . The climate suitability of B. zonata was increasingly high in the projection under climate change. The result of the two models showed that the climatic suitability for B. zonata will increase under climate change in China. Taken together, these predictive results support the quarantine of B. zonata for high-risk countries and provide in-depth information on how climatic changes may affect its possible geographic range.","PeriodicalId":72488,"journal":{"name":"CABI agriculture and bioscience","volume":"29 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136068070","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The recent increase in demand for AIVs brings about the need to match cultivation with consumption to prevent the extinction of these nutritious vegetables through overexploitation. This review aims to assess the most common AIVs and the associated agronomic practices in their production by smallholder farmers in Zimbabwe and SSA in general for potential commercialization. Amaranthus , Cleome gynandra , Bidens pilosa , Abelmoschus esculentus , Vigna unguiculata , Cucurbita spp. and Corchorus molitorius are some of the most consumed AIVs in sub-Saharan Africa. Plant density should balance between leaf quality and leaf and seed yield per unit area. Transplanting and sowing AIVs in lines as pure stand can optimize production when compared to broadcasting. Nutrient application whether organic or inorganic is crucial together with harvesting leaves in 1 to 2 weeks interval and removing flowers to increase budding for optimized AIVs production. There is vast information on the indigenous vegetables found and preferred in SSA but scarce information on their performance under different plant nutrition management regimes and different agroecological regions. Research is required to increase production and to improve the nutrient content of AIVs.","PeriodicalId":72488,"journal":{"name":"CABI agriculture and bioscience","volume":"33 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136263575","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They are also a source of livelihood for many rural communities both as food and as a source of income. Main body This review compiles information on the diversity, distribution, decimating factors, nutrition and conservation concerns of edible saturniids. A compilation of nutritional profiles, amino-acids, mineral and fat content of saturniids is presented. Details of edible saturniids consumption and food plants are listed as well as vernacular names in different parts of Africa. A comparison of collection, processing, storage and trading methods based on available literature is also included. Processing, which is mostly carried out by women, involves tedious and time-consuming methods that need to be improved. Poor handling and storage cause bacterial and fungal contamination that raises food safety concerns. An in-depth discussion of conservation concerns and possible interventions is also provided. Conclusion We conclude that edible saturniids are a source of highly nutritious food and incomes to many households in SSA, but wild harvesting is increasingly becoming unsustainable. We also conclude that the seasonal nature of availability limits their potential for profitable trade Further research on rearing edible saturniids is required since wild harvesting is unsustainable. Training women and youth on mass production technologies will ensure continuous supply of the insects and help preserve their natural habitats.","PeriodicalId":72488,"journal":{"name":"CABI agriculture and bioscience","volume":"2015 15","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135274246","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"The application of allelopathy in integrated pest management systems to control temperate European crop pests: a systematic map","authors":"Charlotte Kiely, Nicola Randall, Magda Kaczorowska-Dolowry","doi":"10.1186/s43170-023-00183-1","DOIUrl":"https://doi.org/10.1186/s43170-023-00183-1","url":null,"abstract":"Abstract Background Pesticides perform vital roles within agriculture but growing concern for their impact on the environment and non-target organisms has created a market for biopesticides with fewer ecological impacts. One source of biopesticides is allelochemicals, here defined as compounds released by an organism that have an inhibitory or stimulatory effect on neighbouring organisms. The focus of this study is allelopathic plants and their inhibitory effects on invertebrate herbivorous agricultural pests of temperate Europe. A systematic map is required to describe the current state of research and collate evidence. Methods Two academic databases were searched for relevant studies in temperate climates. The results were imported into EPPI-Reviewer, duplicates removed, studies screened and data extracted into a searchable database following the inclusion criteria and coding tool set out in the protocol. Screening consistency was checked at each stage using 5% of the studies. Critical appraisal was not conducted. Each unique combination of key variables (pest, plant, allelochemical, application method, intervention form) was treated as a separate datapoint or experiment. The data was then analysed and cross-tabulated to produce descriptive statistics and heatmaps. Results This systematic map produced a database which included 243 studies containing 717 experiments from 5550 initial results. Research was unevenly distributed among all key variables with a distinct bias towards extracted allelochemical experiments under laboratory conditions. Allyl isothiocyanate was the most studied allelochemical and of the 99 identified chemical groups, flavonoids and glucosinolates were the most frequent. A wide range of pest and plant species were identified. Brassicas were the most studied plant family and Lepidoptera the most studied pest order. Physical living plants, as opposed to plant extracts or isolated allelochemicals, were predominantly studied in terms of resistance. Allelopathy application methods were not specified in the abstract of 22% of experiments and only 10% of experiments were conducted under field conditions. Conclusion Allelopathy has been studied in the context of temperate invertebrate pest control in some breadth but little depth and key pest species have not been targeted. The map highlighted significant gaps in the evidence base and a distinct lack of field studies or studies comparing application methods. It contains insufficient evidence to guide policy or management decisions, but provides a research tool and indicates areas for future studies including highlighting topics for secondary research. Critical appraisal is needed to determine allelopathic affect and future search strings should detail all application methods.

To date, several egg parasitoid species are reported to attack BMSB. In this study, two species of Trissolcus (Hymenoptera: Platygastridae) and one Anastatus (Hymenoptera: Eupelmidae) were recovered from field exposed BMSB sentinel eggs in Beijing, China. The wasps’ small size of only 1.5 mm and 4 mm in length make them difficult to identify morphologically and required taxonomist for identification of specific species. In addition, these parasitoids have morphology sibling species and have been misidentified several times in China. To overcome these problems, a molecular method with species-specific primers designed for the COI gene has been developed to identify Trissolcus , Anastatus and their host samples from field collected samples. After successful morphological confirmation with experts, DNA extractions were carried out from these samples. PCR amplification using published primers for T. japonicus , A. japonicus and BMSB specimens confirmed the species. As for T. cultratus , species specific primers TCYF and TCYR were developed which produce 340-bp PCR products length while no positive amplifications found in other wasps and host. Sensitivity analysis of markers revealed that TCYF and TCYR primers could detect as low a DNA template concentration as 0.00025 ng/μL. This indicates that PCR with these primers specifically and sensitively differentiates T. cultratus specimens from other similar wasp species. All the primers tested in this study could discriminate between parasitized and non-parasitized BMSB eggs. This molecular identification method shows promise for conveniently identifying Trissolcus and Anastatus species in host-parasitoid associations and accurately evaluating parasitism rates in the field.","PeriodicalId":72488,"journal":{"name":"CABI agriculture and bioscience","volume":"230 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135252403","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, an unsafe level of fungal toxins is becoming a problem leading to challenges in exporting. This study assessed trends, possible points of Aspergillus contamination, and contamination risk factors along the Ethiopian chili postharvest value chain (PVC). Methods Chili handling practices, value chain actors, and their respective roles were investigated along the PVC through an exploratory type of research, a participant unstructured observation. A total of 214 individual sample units composed of multiple subsamples consisting of aseptically picked matured red pods (PiPP), dried red pods (DPP), crushed chili (CP), unpacked (UpPPo), and packed chili powder (PaPPo) were randomly collected along the PVC from different major chili growing localities of Ethiopia during 2017/2018 main cropping season. Individual sample units were further homogenized into a fine powder and composited. Aspergillus was analyzed using Aspergillus flavus and parasiticus agar medium. To monitor Aspergillus contamination, trend analysis was done using the mean of count data and biological inference was made in association with stages of operations and postharvest handling practices. Results Aspergillus was detected in 44% of PiPP, all (100%) of DPP, CP, UpPPo, and PaPPo. Counts were in the range of 5.00 × 10 3 to 2.10 × 10 5 CFU g −1 up along the PVC with fold changes of 19.6, 30, 42, and 38-fold in DPP, CP, UpPPo, and PaPPo, respectively. Nigri (99%), Flavi (85%), and Circumdati (56%) were the most detected sections with relative densities of 50, 29, and 14%, respectively. Postharvest handling practices such as harvesting, sun-drying, and transporting were generally found poor and unhygienic. Conclusions Counts of Aspergillus showed gradually increasing trends up along the PVC. The poor and unhygienic handling practices probably contributed to the contamination. Harvesting and direct open sun-drying were likely initial and critical points of contamination while wetting and tight stacking likely contributed to aggravated growth and proliferation of aspergilli leading to further consecutive buildup. Intervention at these stages would make a significant difference.","PeriodicalId":72488,"journal":{"name":"CABI agriculture and bioscience","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135590796","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Women are expected to bear the impact of the impact because they are over-represented in affected sectors on the front lines of the pandemic’s response. However, no empirical evidence exists to support the effect of COVID-19 on women’s economic activities in the Ethiopian context. Methods This study investigated effects of COVID-19 on economic activities of rural women in Ethiopia. Thereby, a multistage sampling procedure was employed to randomly draw 263 rural women as study participants. Data were collected through interview schedules and key informant interviews. Finally, the data were analyzed qualitatively and quantitatively. A binary logistic regression model is used to examine factors determining the effect of COVID-19 on economic activities of women. Results According to the findings, the most affected economic activities were remittances (94.28%), small business trade (94.06%), livestock and livestock product trading (91.30%), daily labor wages (84.82%), handcraft (72.73%), and crop production (61.32%). The logit regression result shows that irrigation use reduced the impact of the pandemic, whereas relying on remittances, market distance, and being a female-headed household exacerbated the impact of the pandemic on the economic activities of rural women. Conclusion The pandemic had significant impact on rural women’s economic activities. Therefore, governmental and nongovernmental organizations should support rural women’s income-generating activities by providing revolving funds with training. Using remittances for income-generating activities would also improve the income of rural women.","PeriodicalId":72488,"journal":{"name":"CABI agriculture and bioscience","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135893294","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Early cross-sectional studies reported that the pest causes severe damage to maize, stimulating widespread use of synthetic pesticides in smallholder farming systems. Using panel data from Ghana, this paper assessed the impact of FAW on maize productivity and the changes in the strategies adopted by smallholder farmers for the management of the pest. Methods Household data collected in two rounds (2018 and 2020) from 370 smallholder maize-growing households in Ghana were used. The dynamics of FAW infestation and the management practices applied by farmers were analysed descriptively, while panel data regression methods, such as fixed effects and correlated random effects models, were used to estimate the effect of FAW on maize productivity. Results We found evidence of reduced intensity of pesticide use, increased use of protective equipment when spraying pesticides, increased adoption of biopesticides and cultural practices for FAW management, in line with recommended integrated pest management solutions. Results from panel data regression analysis showed that after controlling for other determinants of maize productivity and unobserved heterogeneity, the negative effect of FAW infestation on maize productivity is not statistically significant.

One of the rootstocks, M9 377 was also grafted with a GD interstock. Two locations in England were selected, the first at East Malling, Kent, the second, at Newent, Gloucestershire. Several variables were analysed including cumulative numbers of dead trees per rootstock from 2017 to 2020, number of rootstock ‘A type’ cankers, number of scion mainstem ‘B type’ cankers, and number of peripheral ‘C + D + E’ branch cankers at the Kent and Gloucestershire locations in the fourth and final assessment year of 2020. Kendall’s rank correlation was used to test if trunk circumference (a measure of tree vigour) and canker were statistically dependant. Results showed that in Kent, there were significant differences between rootstocks for scion B cankers and peripheral C + D + E cankers. There were no significant differences found between rootstocks for rootstock A cankers at Kent, or any of the three canker types in Gloucestershire. There were up to 31.25% dead trees in Kent (EMR-004), and 30% in Gloucestershire (M9 337 with GD interstock, M26), but there were no significant differences in number of dead trees due to rootstock type in either Kent or Gloucestershire. The Kendall’s rank correlation analysis indicated there was almost no dependence of trunk circumference on canker. The three rootstocks with the overall lowest susceptibility to canker were M116, EMR-006, and EMR-004. The industry standard rootstocks M9 EMLA and M9 337 were ranked 12 and 14, and with EMR-001 were the three worst performing rootstocks.

Small-scale farmers have gained recognition as important suppliers of morogo to informal settlements. In commercial production systems, leafy green vegetables have increasingly been reported as associated with foodborne pathogens and disease outbreaks. Little is known of the presence of these organisms on leafy green vegetables in the informal unregulated food systems. This study aimed to profile bacterial communities in irrigation water (flooding and overhead irrigation water) and leafy green vegetables ( Brassica rapa L. chinensis and Brassica rapa varieties of morogo ) to establish the natural bacterial flora at the water-fresh produce interface from five small-scale farms in two provinces in South Africa. Illumina MiSeq high-throughput sequencing showed that each farm exhibited a unique bacterial community composition, with an overall high relative abundance of Proteobacteria, Firmicutes and Actinobacteria, including prominent families such as Burkholderiaceae (48%), Enterobacteriaceae (34%), Bacillales Family XII (8%), Rhodobacteraceae (3%), Micrococcaceae (1.98%) and Pseudomonadaceae (1.79%). Specific Enterobacteriaceae Serratia , Enterobacter , Salmonella , Shigella , Escherichia coli , Buchnera, Citrobacter , Klebsiella and Proteus were identified, in addition to unique communities associated with plant or irrigation water source.
