Population dynamics of Helicoverpa armigera (Hubner) and its parasitization by Campoletis chlorideae uchida in chickpea

Experiments were conducted on three dates of sowing i.e., 20^th October, 15^th November and 1^st December during 2018-19 and 2019-20 at Banda to assess the population dynamics of gram pod borer Helicoverpa armigera (Hubner) and % larval parasitization in chickpea. The incidence of H. armigera was noticed from 49^th to 12^th Standard Meteorological Week (SMW). Its incidence was increased at vegetative stage from 50^th to 1^st SMW in first date of sown crop and at reproductive stage from 10^th to 12^th SMW in 3^rd date of sown crop. The highest and lowest parasitization of larvae by Campoletis chlorideae were recorded as 58.67 and 55.00% (49^th SMW) and 10.67% (12^th SMW) and 7.30% (13^th SMW) during 2018-19 and 2019- 20, respectively. Maximum and minimum temperature showed a negatively by significant correlation with larval parasitization whereas, relative humidity and rainfall had a positively non-significant correlation.
