Abstract:
The field experiment was conducted at the agricultural research farm of Uttar Banga Krishi Vishwavidhyalaya, Pundibari, Cooch Behar, and West Bengal, India in 2019 to 2021 to study the influence of weather parameters on predatory spider population in rice ecosystem of terrain region of West Bengal. Sampling was done at different rice growth stages i.e. nursery, vegetative, reproductive and maturity stages during Kharif and Rabi seasons. Total of 16 species of predatory spider fauna belonging to 6 families of order Araneida were found. In the study it was found that climatic factors also influence the population of predatory spiders to some extent. It was observed that rainfall had direct impact on the population of spiders. The population of spiders was inversely proportional to rainfall during Kharif season while directly proportional to rainfall during Rabi season. During Kharif season spider’s population were mostly negatively correlated with almost all the weather parameters while in Rabi seasons it was positively correlated.
