Journal Title: International Journal of Life Science - Year 2018, Vol 6, Issue 4
Abstract
Western ghat is one of the centre of high biodiversity and renowned for its unique species including insects. The diversity of beetles is very wide ranging, they are found in almost all types of habitat. The present study focuses on the diversity of beetles in different agro ecosystem in Chikkamagaluru. The present survey was conducted for the period of five months from July to November 2015...Efforts were made to study the diversity of beetles in and around chikkamagaluru, in three different habitats such as coffee, Pepper and coconut plantations. During the present survey, total 18species of beetles belonging to 7 families Viz., Carabidae, Cerambycidae, Chrysomelidae, Coccinellidae, Curculionidae, Meloidae, and Scarabaeidae were recorded. The highest diversity was represented in the family Scarbaeidae with 8 species, followed by Chrysomelidae with 3 beetle species and family Carabidae and Meloidae with 2 species and family Cerambycidae, Coccinellidae and Curculionidae, representing one species each respectively. Myllocerus viridians are causing considerable defoliation of herbs, shrubs and trees. Holotrichia serrata causes a serious damage to the sugarcane and ground nut crops. Mylabris pustulata the young ones are beneficial to crops by suppressing other plant feeder which may serves as a biological control of other pest.
