Abstract: Study on seasonal incidence of Campoletis chloridae Uchida, a larval parasitoid of Helicoverpa armigera (Hubner), in chickpea crop was conducted at Kanpur during rabi 2007-08. The parasitoid made its first appearing during 3rd standard meteorological week of the year in different date of sowing and verities varied between 4.4 to 93.3 %. The verity Udai sown at November 11-2007 D1 and D2 November 28 was Mean ± SD 44.75 ± 31.93 and 42.61 ± 27.65, verity Avarodhi date of sown of October 21 2007 D1 and November 17 2007 D2 was Mean ± SD 32.43 ±29.22 and 36.36 ± 29.22 and verity Pragati date of sowing November 17 2007 D1 was Mean ± SD 31.47 ± 31.47 ± 26.79 during December, January, February and March respectively. The per cent parasitization of C. chloridae showed a negative correlation with means temperature, sunshine hours and relative humidity. Where a significant positive correlation was found between per cent parasitization rainfall and wind velocity.
