Species Diversity of Coccinellids in agricultural and horticulture crops ecosystems of Pusa, Bihar, India

The current research paper coveys the species diversity, abundance, evenness and distribution of various species of coccinellid beetles in agriculture and horticulture crop ecosystems. The study was conducted in the farm fields of Dr. Rajendra Prasad Central Agricultural University, Pusa, Bihar, from July-2022 to March 2023. The recognition of these coccinellid beetles reveals that a total of 11 different species affiliated to four sub families viz.,Coccinellinae, Chilocorinae, Epilachninae and Scymninae. Out of four subfamilies, Coccinellinae (63.63%) represented the highest of the total species followed by Chilocorinae (18.18%). Among the species, Coccinella septempunctata Linnaeus was active in both crop systems indicating a wide adaptability representing 24.55% of the total species collected, which was followed by Micrapsis yasumatsui (19.25%) diversity status of coccinellids in both crop systems by computing evenness, Simpson index and Shannon index values concluded that coccinellidae was the most diverse in both crop ecosystem.
