Abstract:

The study had been carried out in the semi-arid region of India at Agronomy farm, S.K.N. College of Agriculture, Jobner (Rajasthan) during Kharif 2018. The insect pests, aphid (Aphis craccivora Koch) and leafhopper (Empoasca kerri Pruthi) were observed as major sucking insect pests infesting on groundnut crop. The aphid and leafhopper population commenced in the last week of July and reached to its peak in the second week of September, when the maximum temperature, minimum temperature, relative humidity and rainfall were 30.0 oC, 21.0 oC, 78% and 1.6 mm, respectively. The population of aphid and leafhopper showed significant negative correlation with maximum temperature and significant positive correlation with relative humidity. The population of predators and maggot of Syrphid fly were appeared in the first week of August and reached to maximum in the third week of September. The populations of both the predators were significant positively correlated with aphid and leafhopper populations. Both predators had non-significant correlation with weather parameters except Lady bird beetle which showed significant positive correlation with relative humidity.
