Abstract:
A field experiment conducted at Research Farm, Rajmata Vijyaraje Scindia Krishi Vishwa Vidyalaya, Gwalior, Madhya Pradesh during kharif, season 2019-20.To study the seasonal incidence of insect pests on clusterbean during kharif 2019, incidence of insect pests were observed on kharif clusterbean, namely flea beetle, phyllotetra vittula, thrips, Megleurothrips distalis (karny), Jassid, Empoasca kerri (Pruthi) aphid, Aphis craccivora (Koch),whiteflies, Acaudaleyrodes rachipora (Singh) and mite, Polyphgotarsonemus latus (Banks). Peak population of Jassid, whitefly and mite were observed during 37th SMW (1st week of September) (5.66, 5.67 and 3.68 individuals/plant, respectively); while peak population of thrips were observed during 38th SMW (2nd week of September) (4.75 individuals/plant respectively), aphid peak population was observed 36th SMW (5th week of August) (4.61 leaves/plant) and flea beetle were observed during 39th SMW (3 rd week of September) (5.20%). Population of thrips, Jassid, and flea beetle showed strong positive significant correlation with rainfall (r= 0.701**), (r= 0.519*), and (0.583*) respectively. Population of jassid and showed highly significant positive correlation with maximum temperature, morning & evening RH (r= 0.795**), (r= 0.802**) and (r= 0.803**) respectively. Population of jassid showed significant negative correlation with minimum temperature (r= -0.643**). Aphid population morning and evening RH showed positive and significant value of correlation coefficient (0.531*), (0.550*). Whitefly population evening RH and rainfall was found only significant (0.596*), (0.636*).population of flea beetle morning RH and rainfall (0.867**), (0.583*) significant to highly significant while strong negative correlated (-0.710**).
