“…In Maharashtra, a comprehensive list of 25 pests has been documented to cause damage at various stages of growth (Manjunath, 2004) [12] . Among these, major sucking pests including Aphids, Jassids, Whiteflies, and Thrips are consistently cited as significant threats, posing substantial challenges to cotton cultivation across different regions (Bhamare and Wadnerkar, 2018) [2] . Environmental factors such as temperature, humidity and precipitation play a pivotal role in shaping the behaviour of these pests in cotton fields (Deshmukh et al, 2023) [7] .…”

A field experiment conducted over Kharif seasons of 2020 and 2021 at All India Coordinated Cotton Improvement Project, MPKV, Rahuri, examined the impact of weather factors on sucking pest populations in Bt cotton. The data reveal that aphids were predominant, ranging from 4.60 to 120.86/3 leaves in 2020 and 0.64 to 63.60/3 leaves in 2021. Jassids ranged from 2.04 to 11.46/3 leaves in 2020 and 0.52 to 5.76/3 leaves in 2021. Thrips ranged from 0.26 to 13.78/3 leaves in 2020 and 0.18 to 57.46/3 leaves in 2021. Whiteflies varied from 0.24 to 8.32/3 leaves in 2020 and 0.04 to 5.82/3 leaves in 2021 with peak activity recorded in the 42 nd SMW of 2020 and the 46 th SMW of 2021. Natural predators like lady bird beetles, green lace wings and predatory spiders were observed throughout the cropping season, showing peak activity in specific weeks.
