Twenty-four insect pests were identified causing damage to pomegranate at various growth stages in pest succession studies. On the pomegranate environment, five sucking pests (aphid, thrips, whitefly, mealy bug, and mites), one fruit borer (anar butterfly), and three leaf defoliators (castor semi-looper, tussock moth caterpillar, and hairy caterpillar) predominated. Thrips, Scirtothrips sp., and fruit borer, Deudorix sp. were identified as important pomegranate insect pests. Based on the pooled mean, Neem Seed Kernel Extract (NSKE) @ 5% outperformed other botanical insecticides in terms of thrips and fruit borer infestation, with 2.11 thrips/5 cm shoot and 4.96 percent, respectively.","PeriodicalId":15705,"journal":{"name":"Journal of Entomology and Zoology Studies","volume":"41 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87098106","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}

Any food crop's yield is influenced by pest incidence in addition to soil properties. In multiple investigations, the polyphagous Omiodes indicata (Fabricius) (Lepidoptera: Pyralidae) was identified as a potential pest to various crops. During 2016 and 2017, early-maturing black gram ( Vigna mungo L.) was grown in fallow rice fields in Hajo revenue circle (26.3303 0 N, 91.5148 0 E) in the Kamrup District of Assam. Larvae of Omiodes indicata were counted visually at the experimentation site. This species was discovered in all three plots of the experimental agricultural area. It fed on the green parts of the leaves reducing the chlorophyll content. During the vegetative stage, the population level indicated an increase in its size. Omiodes indicata (larva) was first discovered in the 36 th standard week with a mean population of 0.8/plant and reached its peak in the 39 th standard week with a population of 1.53/plant in 2016. With a mean population of 0.2/plant, the first appearance in 2017 happened during the 37 th standard week. In the same year this pest reached its peak during the 40 th standard week, with a mean population of 1.46 per plant. These findings are significant for both the crop and the local farmers, necessitating managerial attention in order to achieve the projected level of yield.","PeriodicalId":15705,"journal":{"name":"Journal of Entomology and Zoology Studies","volume":"86 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89370285","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}

Among vegetable plant species, brinjal (Solanum melongena L.), tomato (Solanum lycopersicum L.), okra (Abelmoschus esculentus) etc., are severely damaged. Present studies were carried out to investigate the impact of these three host plant species on the life history of the mealybug in the laboratory. Age, stage specific and female fertility table data were used for this analysis. Okra has been found most suitable host among the tested plant species. Shortest development period (52 days), longest fertility period (21 days) and natality (163 eggs/female) were recorded on okra. In addition, highest values of intrinsic rate of increase (rm) (0.09569±0.002 day−1), the finite rate of increase (λ) (1.10±0.002 day−1), and net reproductive rates (R0) (38.60±2.35 offspring per individual) were also recorded on okra. On the other hand, the longest mean generation time (T) (48.95±2.88 days) and doubling time (DT) (11.55±1.25 days) were observed when P. solenopsis was reared on tomato. The tomato was the least preferred host for P. solenopsis. This variation in host preference can be utilized in predicting the dynamics of the P. solenopsis, and in determining the timing of pesticide application as well as release timing for natural enemies to achieve better control of this pest. Further, okra can be used as trap crop to facilitate effective management of this pest.","PeriodicalId":15705,"journal":{"name":"Journal of Entomology and Zoology Studies","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135736482","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}

This research work was carried out to analyze the monthly length-weight relationships (LWR) with the construction of generalized relationships of body weight to standard length measurements and the condition of H. limbatus for males and females separately. A total of 524 specimens (228 males and 296 females) used in this study were sampled from the Kangsha River in Netrokona, Bangladesh over a year from September 2020 to August 2021. The results revealed that length-weight relationships were highly correlated (r>0.730) in H. limbatus. The parameters of the equation W=aLb describing the relationships between body weight and standard length for male and female varied monthly. The generalized LWR was fitted with the pooled data of all monthly samples for male and female separately. In case of male, the parameters of equations (a) varied monthly from 3.30 to 7.24 and the slope of equations (b) varied from 2.02 to 3.68. In case of female, the coefficient of equations (a) varied monthly and it ranged from 4.2905 to 9.504 and the slope of equations (b) varied from 2.18 to 3.92. The higher value of regression co-efficient (b) was found either due to maturation of gonad or due to favorable feeding environment. In case of males, fish growth was both positive and negative allometric. In case of females, fish growth was negative allometric except in September, December, June and July. Monthly relative condition factors based on CFBW values ranged from 1.0187 to 1.2070 for male, the lowest condition factor appeared on October 2020 and the highest was on May 2021. In case of female the relative condition factors based on CFBW ranged from 1.1117 to 1.4281, the lowest condition factor appeared on February 2021 and the highest condition factor appeared on April 2021 for female.
