Farming systems built on integrated pest management (IPM) can minimize the use of chemical pesticides and secure soil, plant, and human health by controlling pests at the same time. Bactrocera cucurbitae is a serious pest of cucurbitaceous crops including more than other 70 hosts. Though various control strategies have been developed against melon fruit flies, fewer efforts have been paid to establish effective and efficient integrated pest management programs. This review provides an overview of the life cycle and behaviour of melon fruit fly as well as a detailed analysis of the various IPM strategies that have been developed for their control. These strategies include cultural practices, such as weeding, removal of alternate hosts, and field sanitation, biological control methods such as use of natural enemies, and entomopathogenic fungi (Beauveria bassiana, B. pseudobassiana), use of botanicals (neem, jholmol), and chemical control measures, such as the use of pesticides.Keywords: Bactrocera cucurbitaeIPMcontrolyield lossmanagement AcknowledgmentsWe would like to thank our parents, friends, and professors from Agriculture and Forestry University who helped directly and indirectly during the process of manuscript preparation.Authors’ contributionsPramod Gyawali analysed the data and prepared the manuscript.

The effectiveness of chemical insecticides has been compromised due to insecticide resistance and concerns over their environmental impact, which necessitated an alternative approach that is safe and more sustainable. The study aimed to determine the effectiveness of Entomopathogenic fungi (EPF), Metarhizium anisopliae and Beauveria bassiana in controlling AfRGM on four popular rice cultivars under screenhouse conditions at AfricaRice/IITA, Ibadan, Nigeria. The experiment was laid out in a 4 x 3 factorial fitted in a completely randomized design (CRD) in three replications. Results showed that although both fungi significantly reduced AfRGM tiller infestation, the degree of reduction varied with the specific fungus and rice variety grown. Beauveria bassiana exhibited better control of AfRGM on FARO 37 and FARO 44 varieties, while M. anisopliae was more effective on FARO 66 and FARO 67 varieties. Tiller infestation had a significant negative correlation with grain yield (r= − 0.87, R2 = 77). The study also indicated that the two fungi strains had no harmful effect on the chlorophyll content and positively influenced agronomic traits and grain yield.Keywords: Entomopathogenic fungiMetarhizium anisopliaeBeauvaria bassianaAfRGMricetiller infestation AcknowledgementsThe authors gratefully appreciate Dr Douro Kpindou for providing the EPF isolates from IITA laboratory, Benin Republic and Mr. Adebayo Kehinde for technical assistance.Disclosure statementNo potential conflict of interest was reported by the author(s).Data availability statementData will be made available on request.","PeriodicalId":14275,"journal":{"name":"International Journal of Pest Management","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135265908","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To assess farmers’ knowledge on host and management approaches of this pest, a survey of 240 farmers was conducted in eight districts of Bangladesh. Farmers noticed an expanding dispersion of this pest in Bangladesh since 2019. Among all the districts examined, Cox’s Bazar district was highly infested. Farmers mainly cultivated local coconut varieties in their homesteads. Forty percent (40%) of the farmers among all districts estimated that the pest reduced coconut yield to more than half. Only 1% of all farmers knew about all life stages of the pest. Consultation with extension officers significantly improved farmers’ knowledge of the pest. Summer was the peak season for the whitefly infestation. Farmers identified 22 hosts of the pest and almost four out of ten (40.4%) applied management methods against the pest. Among them, 22% used chemical methods, 42% used non-chemical methods, and 24% used both methods.

S. hermonthica seedbanks in savanna soils have continued to rise due to poor agronomic practices by smallholder farmers. Considering differences in soil, climate, and agronomic practices within the savanna endemic agroecology, the severity of the infestation of S. hermonthica has varied from one location to another. Hence, there is a need to model a site-specific management approach for S. hermonthica in Nigeria. This review aims to understand the state-of-the-art management of S. hermonthica in Nigeria’s upland rice fields and further harmonize potential management approaches. Based on studies conducted in Nigeria, reducing S. hermonthica parasitism over a long-term period in the Savanna ecology of Nigeria implies the rotation of upland rice with trap crops, and enhancement of nitrogen fertility in farmers’ fields, combined with the use of seed-treated resistant or tolerant cultivars. In practical terms, farmer’s-research engagement in the long term is pertinent to reduce the severity of S. hermonthica in threatened areas.Keywords: Striga hermonthica (Del.)

Its impact resonates in India, where it has emerged as a formidable pest. Moreover, the excessive use of chemically-derived pesticides has led to the emergence of insect-resistant strains, resulting in environmental pollution and endangering human health. The use of natural enemies is a sustainable and environmentally safe alternative management tactic. The predation potential of green lacewing, Chrysoperla zastrowi sillemi Esben-Peterson (Neuroptera: Chrysopidae) on eggs, nymphs and adults of B. tabaci infesting parthenocarpic cucumber grown under polyhouse has been examined here. On cucumber plants, three releases of 2nd instar C. zastrowi sillemi larvae (at one, two and three larvae/plant) were made at 7 days intervals. The release of three larvae/plant resulted in significantly higher predation rate on whitefly population (58.6% on egg, 61.0% on nymph and 32.3% on adult stage of the whitefly) than two or one green lacewing larvae/plant (56.3% on egg, 58.3% on nymph and 30.4% on adult stage of the whitefly & 49.9% on egg, 51.0% on nymph and 24.6% on adult stage of the whitefly, respectively). Significantly higher yields of cucumber were recorded from plots with the release rate of three larvae per plant (2047.9 g/plant). Augmentative biological control of B. tabaci under polyhouse conditions with three weekly releases of 2nd instar C. zastrowi sillemi larvae at three larvae per plant can effectively manage whitefly infestation on parthenocarpic cucumber under polyhouse condition.Keywords: Biological controlmarketable fruit yieldpredation efficiencyprotected structuresvegetable cropwhitefly AcknowledgementsThe authors are grateful to the Dr. Pardeep Kumar Chhuneja, Professor of Entomology and Head, Department of Entomology, Punjab Agricultural University, Ludhiana, India, for providing infrastructure and necessary facilities during the study.

For this reason, a survey of 144 cashew farmers was conducted from June 2020 to December 2022. Tea mosquito bug (70.1%), cashew stem and root borer (52.8%), and apple and nut borer (45.8%) were the top-ranked among 21 insect pest species of cashew. The highest insect pest infestation was observed in the tender leaves (49.8%). Overall, 56.3% farmers noticed 11–20% yield losses caused by insect pests, while 9% of the farmers believed that yield losses could be more than 40% in cashew orchards. Although physical (7.7%) and mechanical (7.6%) pest management tactics, like hand-picking, use of coal tar, kerosene, and yellow sticky traps were used to control pests, most farmers (84.7%) relied on chemical pesticides. Young and educated farmers were interested in non-chemical pest management options compared to their counterparts.

Results showed that individually-reared CPBs were significantly better than that of group-reared CPBs, in terms of intrinsic rate of increase (0.07), finite rate of increase (1.07), net reproductive rate (39.93), and gross reproductive rate (221.23) compared to that of group-reared treatment (0.05; 1.05; 10.84; and 58.77). Additionally, individually-reared CPB populations had faster development, characterized by shorter generation cycles, and higher female survival rates, which produced more offspring per unit time, compared to the group-reared CPB population. However, in potato fields, the CPB are mostly found in groups and therefore the group-rearing method should be more effective for prediction and possible management of CPB populations.
