Coccinellids of Some Cropping Fields of Eastern Uttar Pradesh, India

Abstract

Several intensives surveys were made to explore the diversity of Coccinellid fauna from Rice (Oryza sativa L.); Wheat + Mustard (Triticum aestivum .+ Brassica compestris L.) and  sole Mustard (Brassica compestris L.) cropping field of the eastern Uttar Pradesh, India during 2018-2020. Different Diversity indices like, Shannon diversity index (H); Simpson index (D); Simpson diversity index (1-D); Evenness (E) were used for studying diversity and abundance of coccinellid beetles. The results revealed that 2627 predator and phytophagous coccinellids were recorded belonging to 12 species under 10 genera from three tribes of the family Coccinellidae. The Coccinella transversalis Fab. (22.00%) was more common species whereas, Anegleis cardoni (Weise) (1.0%) as least common species was recorded during the whole observation in the all-cropped field. The all indices showed very good diversity and richness of the coccinellid fauna in all the cropping fields during the investigation. The comparison of the indices, richness and evenness among the different cropping field, T. aestivum +B. compestris field showed that more coccinellid fauna diversity followed by the B. compestris field perhaps, more availability of prey and pollens.
