Population Dynamics of Defoliator Pests of (Arachis hypogea L.) in Different Staggered Sowings

The present study was conducted to assess the incidence of defoliator pests of groundnut in three different staggered sowings. The experiment was laid with three treatments and seven replications which was carried out at RARS (Regional Agricultural Research Station), Palem, Nagarkurnool district, Telangana state which is having hot and dry climate. The data has been correlated with various weather parameters, including Maximum temperature, Maximum temperature, RH-I and RH-II. The variety K-6 was grown in three staggered sowings (D1: 1st Oct; D2: 15th Oct; D3: 1st Nov). There was a less population of leaf miner during D1 the correlation studies revealed that tobacco caterpillar showed a non-significant negative correlation with the Tmax ºC (r= -0.233) and a significant positive correlation with Tmin ºC (r= 0.370) and RH-? (r=0.640). whereas gram caterpillar showed a positive significant correlation to Tmax (r= 0.256) and Tmin (r= 0.097) and a negative significant correlation towards RH-? (r= -0.186) and RH-? (r= -0.501).
