Variability of Nocturnal Insects In Sant Gadge Baba Amravati University Campus, Amravati

Abstract

The insects are known to be the most successful and diverse animals on earth. Variability of nocturnal insects in Sant Gadge Baba Amravati University campus was recorded by using the light trap method for collection of insect. This trap consists of the light source and a big white sheet. The sheet was hung on the pillars. Insects were attracted to the light source settled on the sheet. The second sheet was also spread on the ground to catch the insect that fall. Collected insect in the killing bottle by beating tray aspirator, and forceps. Lightning hours were set for seven hours. During this study, total 6 orders of species of insects are found are Coleoptera, Lepidoptera, Orthoptera, Hemiptera, Diptera, and Hymenoptera, insects belonging to different families was collected in university campus by using light trapping methods respectively and moderate species diversity were observed. The abundance of species of most night insect in the study area maybe due to the loss of their natural habitat. This may be the virtue of anthropogenic activity such as fragmentation of habitat, replacement of the habitat for humane purpose or may be other due reasons that eventually lead to the decline of species diversity.
