The field experiment was conducted at BTC College of Agriculture and Research Station, Bilaspur, Chhattisgarh, during 2016-17. Study about seasonal incidence of predominant lepidopteran insect-pests in soybean crop the soybean leaf folder (Omiodes indicata Fab.), tobacco caterpillar (Spodoptera litura Fab.), green semilooper (Chrysodexis acuta Walker), leaf webber (Anarsia ephippias Mullar) and pod borer (Helicoverpa armigera Hub.) were major defoliator insect causing damage at various growth stages of the soybean crop. The peak activity of Omiodes indicata Fab. (1.67 larvae/mrl) and Spodoptera litura Fab. (1.47 larvae/mrl) were observed during third week of September. Whereas, Chrysodeixis acuta (1.0 larvae/mrl), Anarsia ephippias (0.6 larvae/mrl) and Helicoverpa armigera (0.67 larvae/mrl) were recorded during first week of September, third week of August and fourth week of August, respectively.

... [1] Among this pests, leaf eating caterpillar, S. litura is major defoliator causing damage at various growth stages of soybean crop. [2] S. litura causes 26.06 to 52.01 per cent yield loss in soybean. [3] Considering the economic impact of this insect, this study was conducted to evaluate the effectiveness of chemical insecticides against S. litura in soybean crop. ...

... A correlation study shows that the population of the leaf miner positively correlated with the minimum temperature and sunshine hours and negatively correlated with the rest of the factors. However, according to Singh et al. (2018), the presence of the tomato leaf miner began on January 16 th , with 1.05 live miners per leaf. The pest's activity peaked during the fruiting stage, with 31.25 mines per leaf. ...

... Among the natural enemies of various insect pests in tomato crops, Chrysoperla zastrowii is notably effective. Green lacewings, primarily species of Chrysoperla, are fragile, bright green to greenish-brown insects that are prevalent in tomato crops from mid-October to early April [36]. The population dynamics of Chrysoperla carnea on tomato crops during the Rabi season of 2007-08 showed a gradual increase, starting at 0.22 individuals per plant in early February and peaking at 1.52 individuals per plant on March 19. ...
