Seasonal Variation of Major Insect Pests of Mungbean in Grid Region, Madhya Pradesh, India

During kharif 2022, the experiment was conducted at RVSKVV, College of Agriculture Gwalior, Madhya Pradesh, India, to investigate the seasonal incidence of the main mung bean insect pests. Three sucking insect pests were found to be present from the vegetative stage to the maturity stage: the aphid, Aphis craccivora, the leafhopper, Empoasca kerri, and the whitefly, Bemisia tabaci. We observed two lepidopterans from the reproductive stage to maturity: Spodoptera litura and Lampides boeticus. We saw two lepidopterans from the reproductive stage to maturity: Spodoptera litura and Lampides boeticus. The 39th SMW had the highest prevalence of A. craccivora and B. tabaci, with populations of 1.45 aphids per plant and 7.55 whiteflies per plant, respectively. On the 40th SMW, E. kerri's population peaked at 4.95 adults per plant. The 38th SMW saw a high of 0.52 larvae per plant for S. litura and 0.21 larvae per plant for L. boeticus. According to correlation studies, the maximum temperature was significantly correlated negatively with A. craccivora, B. tabaci, and L. boeticus (r = -0.667, -0.679, and -0.680). A substantial negative connection (-0.697) was observed between S. litura and maximum temperature, whereas a strong positive association (r = 0.704) was seen with evening relative humidity.
