Abstract:

The population dynamics of sucking pests Bt cotton along with their correlation with weather factors were studied during 2008-2013 in five talukas of Buldana district, Maharashtra. According to five year average data the maximum aphid population (43.56 per cent) was recorded in 33rd meteorological week whereas jassid population were reached maximum of 4.42 jassid in 37th meteorological week. The population of thrips was more abundant (6.96 thrips/3 leaves/plant) on the crop in 36th meteorological week. In case of white fly, maximum population of 6.57 whiteflies per 3 leaves per plant was recorded in 37th meteorological week whereas, minimum of 0.82 whiteflies recorded in 31st meteorological week. Among the weather parameters maximum temperature showed positive correlation with A. bigutulla bigutulla, T. tabaci and B. tabaci except whitefly whereas, minimum temperature showed positive correlation with all above mentioned sucking pests. The rainfall favored the activity of all sucking pests with positive correlation except whitefly.
