Population dynamics studies on sucking insect pests viz., whitefly (Bemisia tabaci), jassid (Empoasca kerri) and thrips (Caliothrips indicus) of mungbean [Vigna radiata (L.) Wilczek] were carried out at Genetics and Plant Breeding Research Farm of Acharya Narendra Deva University of Agriculture & Technology, Kumarganj, Ayodhya (UP), India during Kharif 2017. The weekly observation of sucking insect pests of mungbean recorded from 20 days after sowing till harvest. Population of whitefly and jassid were observed from 36 th SW and continued up to 42 nd SW. The maximum and minimum population of whitefly was recorded in 41 st SW (4.9 whitefly/cage) and 36 th SW (3.6 whitefly/cage), respectively. The overall population of jassid ranged from 3.6 (42 nd SW) to 4.7 (39 th SW) jassid/cage. The thrips population recorded from 38 th SW to 42 nd SW and had highest population of 1.2 thrips/5 plants during 41 st SW. Lowest population of thrips was recorded in 38 th SW (1.1 thrips/5 plants).
Evaluation of Mungbean Genotypes Against Major Insect Pests
Indian Journal of Entomology
Field experiment was conducted to screen thirteen genotypes of mungbean against major sucking and lepidopteran pests. The incidence of pests was assessed at 15 DAS (Days after sowing) and continued till maturity at weekly intervals. The results revealed that least mean whitefly Bemisia tabaci (Genn.) incidence/plant was observed in genotype Virat (5.17), TM-37 (5.31) and Shikha (5.40). Similarly, the least aphid Aphis craccivora Koch incidence was on Virat (2.73), Shikha (2.77), TM-37 (2.89) and PDM-139 (2.91). The genotypes, Virat (1.26), Shikha (1.26), PDM-139 (1.30) and TM-37 (1.31) were with lowest leaf hopper Empoasca kerri Pruthi counts; and the least larval counts of tobacco caterpillar Spodoptera litura (F.) was in Shikha (0.22), Virat (0.24), PDM-139 (0.25), TM-37 (0.28) and TJM-196 (0.31). Similarly, least incidence of blue butterfly Lampides boeticus L., larva was observed on Virat (0.21), Shikha (0.23) and PDM-139 (0.26) genotypes. Thus, the genotypes viz., Virat, TM-37,...

Mung bean, Vigna radiata (Linn.)Wilczek (Family: Leguminosae, Subfamily: Papilionaceae) is the third most important pulse crop after chick pea and red gram in India (Ved et al.,2008). In India, mungbean is grown in 2.92 million ha, with a 1.42 million tonnes production with a productivity of 486 kg per ha (Dixit, 2005). Mungbean yields are greatly depressed by a complex of biotic and abiotic factors of which insect pests are the most important. The major constraint responsible for poor yields is the wide array of insect pests, which attack the plants from seedling to maturity. About 65 species of insects (Siddappaji et al., 1979) has been recorded on mungbean. About half a dozen insect species are of major importance (Vyas, 1978). In India, quantitative avoidable losses (7-35%) caused by insect pest complex, both in mung bean and urd bean vary with different agro-climatic conditions (Hamad and Dubey,1983) . The annual yield loss due to the insect pests has been estimated at about 30...

The present investigation were carried out of field studies for two consecutive seasons, winter and summer seasons of 2015 to 2016, at the instructional farm of Uttar Banga Krishi Viswavidyalaya, Pundibari, Cooch Behar, West Bengal. Five cultivars of cowpea and nine cultivars of mungbean were used and the experiment was laid down in a randomized block design and replicated thrice. Population of insect pests was recorded at weekly interval throughout the crop growing period starting from 1st appearance of the pests. The activity of major insect pests on cowpea initiated after one month of seed germination. Crop stage of one and half month age found to be most vulnerable to pests. On both the season a peak aphid population was found during flowering stage of the crop. Highest population of predator was found during 50th standard week on cowpea (0.5 plant-1) and mungbean (0.8 plant-1). Population of insect visitors was recorded from all the varieties of cowpea during winter and summer ...

This study was conducted to examine the resistance in eight advance mungbean genotypes in comparison with two check varieties against sucking insect pests under natural field conditions at Nuclear Institute for Agriculture and Biology (NIAB), Faisalabad. Findings of the trial showed that none of the tested genotypes have complete resistance against sucking pests i.e., whiteflies, thrips and jassids. Comparison of resistance among the tested genotypes against whitefly showed that the lowest number of whiteflies per leaf (3.7±1.20) was observed in MH 3153, lower than those of both checks, whereas, the highest (11±1.53) was observed in MH 34143. Number of thrips per leaf was observed the lowest (4±1.00) and the highest (12.3±0.67) in cultivar MH 3153 and MH 34143, respectively. Similar population trend of jassid was observed with per leaf population of 1.2 and 3.3, the highest and the lowest in MH 3153 and AZRI 2006, respectively. Among all the tested cultivars, MH 3153 gave the highes...

A field study was conducted to evaluate one combination of seed treatment with imidacloprid (Confidor 70 WS) and spray with detergent and for insecticide sprays: imidacloprid (Confidor 20% SL), acetamiprid (Acelan 20% SL), thiomethoxam (Actara 25 WG) and acephate (Commando 75 SP), against sucking insect pests on mungbean, Vigna radiata (L.) at Arid Zone Research Institute (AZRI), Bhakkar during 2012. All the treatments showed a significant difference with one another, regarding their effectiveness. The application of insecticide sprays immediately enhanced the mortality of the pests, whereas, the effect of seed-treatment and detergent did not show distinctive effect on the pests' population. Imidacloprid and thiomethoxam resulted in a maximum mortality of the jassid, followed by acetamiprid. While in case of whitefly, imidacloprid was the most effective and resulted in a minimum population followed by acetamiprid. Acephate resulted in the maximum control of thrips and was found the most effective insecticide, followed by acetamiprid.
Varietal Screening of Mungbean against Whitefly and Aphid
Journal of Bioscience and Agriculture Research, 2018
The experiment was conducted for varietal screening of mungbean against sucking insect pest whitefly (Bemisia tabaci) and aphid (Aphis gossypii). Different mungbean varieties i.e. BARI Mung-1, BARI Mung-2, BARI Mung-3, BARI Mung-4, BARI Mung-5 and BARI Mung-6 were used as treatment for this study. The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. Data on different parameter were recorded and statistically significant variation was observed for different varieties. Among the varieties, BARI Mung-6 showed the least whitefly and aphid population and highest resistance against whitefly and aphid infestations at different stages than all other varieties. The highest seed yield (1.82 t ha-1) was recorded from BARI Mung-6, while the lowest (1.30 t ha-1) was recorded from BARI Mung-4. It means that BARI Mung-6 were superior to other varieties in terms of lowest whitefly and aphid infestation and maximum yield.
