Cotton production and area under cotton is continuously declining in Pakistan for the last five years due to a rapid proliferation of the pests. The current study was conducted to evaluate the efficacy of some new chemistry insecticides against cotton whitefly (Bemisia tabaci) during the kharif season of 2019 in a major cotton producing area of Punjab, Pakistan. A total of ten insecticides (single or mixtures) i.e. Dinotefuran + Spirotetramat (T1), Dinotefuran + Spirotetramat (T2), Pyriproxyfen+ Spirotetramat (T3), Pyriproxyfen+ Spirotetramat (T4), Spirotetramat (T5), Spirotetramat (T6), Pyrifluquinazon (T7), Pyrifluquinazon (T8), Flonicamid (T9), Flonicamid + Abamectin (T10) were applied twice in a field experiment on two varieties of cotton (MNH-90 and BS-18) using randomized complete block design. Water (T0) served as control. There were three replications of each treatment. Data for population of whitefly (nymphs and adults), natural enemies and boll weight were recorded 3, 7, 10 and 14 days after treatment of insecticides. Pyrifluquinazon @ 48.7 g/acre (T8) caused the maximum mortality (83%) of adults of whitefly while the maximum nymphal mortality (78.4 %) was observed in T8 (Pyrifluquinazon @ 48.7 g/acre). The maximum increase in boll weight (133%) was observed in T8 (Pyrifluquinazon @ 48.7 g/acre) followed by T10 (Flonicamid+Abamectin) which gave 110% increase over control. The application of Pyrifluquinazon @ 40 g/acre was found to be safer as compared with other tested insecticides with the minimum reduction of 31% in the population of natural enemies. It is therefore concluded that Spirotetramat and Pyrifluquinazon can be successfully included in IPM programs against Bemisia tabaci.","PeriodicalId":8506,"journal":{"name":"Asian Journal of Agriculture and Biology","volume":null,"pages":null},"PeriodicalIF":2.2,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48944585","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 objective of the study was to explore the relationship amongst morphological traits and body weight (BW) of Ross 308 chicken breed. Morphological traits were recorded on one hundred Ross 308 chicken (male = 50, female = 50) at Broiler Production division of Potchefstroom College of Agriculture, South Africa. The data was analysed using stepwise regression, Pearson’s correlation and Principal Component Analysis (PCA). Correlation findings in females ranged from -0.16 to 0.51 while ranged from -0.07 to 0.56 in males. PCA results extracted only three and two components in males and females chicken, respectively, which contributed remarkable 67.78% and 57.15% of variation. The specified principal components extracted contributed excellently to describe overall structuring. Regression results revealed that use of components was more appropriate than the use of correlated morphological traits in predicting BW. The SC might be used as a key morphological trait in the selection criteria to advance BW of male chickens while SL might be used as a key trait in the case of female Ross 308 chickens.","PeriodicalId":8506,"journal":{"name":"Asian Journal of Agriculture and Biology","volume":null,"pages":null},"PeriodicalIF":2.2,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69848158","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}

It arises a concern on livestock cultivation, their production, and maintaining the supply chain to sustain the existing economy worldwide. The prediction of potential consequences on livestock production and food security is unexpected. Numerous cases among workers in animal farms and product processing plants are evolved during the panic situation, leading to a negative impact on livestock management, and the distribution of products to human doors simultaneously. One of the significant contributions to the drastic decline in livestock operation is the high cost of animal feed. Social distance also slows down all regular activities in livestock farms, resulting in a considerable upset on outcomes. Not only that shutting down transportation flexibility leads to be a burden for farmers in case of high production costs. In the context of consumers, the sublime price of meat, milk, and eggs has addressed the exacerbating risk to worldwide nutrition security. Hence, the world is experiencing an outbreak challenge in resilient, fair, and flexible animal production systems and ensuring food safety globally.","PeriodicalId":8506,"journal":{"name":"Asian Journal of Agriculture and Biology","volume":null,"pages":null},"PeriodicalIF":2.2,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69848307","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}

Snail slime was collected from forty-five snails comprising the three species of snails from the southwestern region of Nigeria. The antibacterial potential and bacteria growth rate (in hours) of the mucus mucin were determined using agar well diffusion method and liquid broth. Acetic acid (acid), ammonium bicarbonate (alkaline), and water (aqueous) were each used to extract the slime. The result showed that mucus secretions from the three snail species differed in color, degree of the sliminess, and volume. Snail mucus extract had antimicrobial effects on gram-positive and gram-negative bacteria. The inhibitory effects of mucus extracts differed depending on the treatment method and storage time, with acid extracts having a higher inhibitory capacity regardless of snail species or storage time. A. marginata's mucus secretions had a stronger antibacterial activity against Bacillus subtilis when compared to mucus from A. achatina and A. fulica. The zone of inhibition of the mucus mucin in solid agar ranged between 24.0–19.5mm for A. marginata and ranged between 21.0-17.5mm and 21.0–15.0mm for A. achatina and A. fulica , within 2-72 storage hours).

The objective of this study was to assess a recently collected cowpea germplasm from Togo for resistance to C. maculatus . A total of 200 cowpea accessions from the five regions of Togo and five checks were screened for resistance to C. maculatus using a no-choice assay. The experiment was laid out in a completely randomized design (CRD) with three replications. Data were collected on average number of eggs laid (ANEL), average number of adult emergence (ANAE), number of holes per seed (NHPS), initial and final seed weight (ISW and FSW), median development period (MDP), percentage adult emergence (PAE), and percentage weight loss (PWL), and two indices of resistance computed viz. insect growth index (G.I.) and Dobie’s susceptibility index (DSI). Data collected were subjected to analysis of variance, Pearson’s correlation and stepwise multiple regression analysis. A total of 51 accessions were moderately resistant, among which RS009 and RP218 had the least DSI score. The remaining accessions (149) were susceptible. DSI was significantly correlated with ANAE, PWL and NHPS, and had a significant and negative correlation with MDP. The results of the stepwise multiple regression showed ANAE, PWL and MDP were the better predictors of cowpea bruchid resistance and accounted for 87.7% of the observed variation in DSI scores.","PeriodicalId":8506,"journal":{"name":"Asian Journal of Agriculture and Biology","volume":null,"pages":null},"PeriodicalIF":2.2,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69848628","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}

DPPH, ABTS, RP and TAC were applied to assess their potential in vitro antioxidant activity. Drosophila melanogaster flies were experimental objects used to evaluate in vivo antioxidant activity. Based on the data analyzed, extract of the plant Momordica charantia L. was resulting in the greatest phenolic content at 64.63 ± 1.51 mg GAE/g extract and flavonoid content at 196.52 ± 5.76 mg QE/g extract. The analyzed result of antioxidant activity through ABTS, RP, and TAC methods also displayed the highest IC 50 values of this plant extract, which was 60.02 ± 2.51 µg/mL, 69.64 ± 2.74 µg/mL, and 110.95 ± 1.65 µg/mL, respectively. Meanwhile, a maximum IC 50 value of 168.30 ± 6.97 μg/mL, which was collected through the scavenging activity by DPPH, was introduced in the extract of Morus acidosa Griff. However, this value was insignificantly different as compared with the IC 50 values of Morinda citrifolia L. extract at 172.30 ± 5.23 μg/mL and Momordica charantia L. extract at 188.20 ± 7.52 μg/mL. Under paraquat and H 2 O 2 -induced oxidative stress conditions, the adult fly, which was fed on extracts, had increased parameters of mean lifespan, 50% survival time, and maximum lifespan. These findings showed that Momordica charantia L. extract had the highest in vivo antioxidant activity among the investigated plant extracts.
