Management of Forest : The Effect of Global Warming Towards Insect Fauna on Forest Area

Abstract

Study of insect fauna on forest area was conducted from July to August 2019 to determine the diversity and abundance of beetle fauna at Burni Geureudong Forest, Takengon, Central Aceh. The study was conducted at two sites namely trail I and trail II. The beetles were sampled using 2 light traps, 2 malaise traps and 20 pitfall traps. Total of 219 beetle specimens comprising of 67 species from 24 families were collected. Light trap collected the most number of beetles (N=117) and Margalef index showed that the most abundant beetle was collected by light trap (Margalef index, 27.551). Shannon-Weiner index shows that the most specious beetle was caught by light traps (4.399). The most abundant family caught was Staphylinidae (Margalef index : 2.667) and specious beetle family caught was the Chrysomelida (Shannon Weiner : 1.846) followed by the ground beetle family Scarabaeidae (Shannon Weiver:1.828). Result of this findings showed that Burni Geureudong Forest is an undisturbed forests and has been preserved well.
