Diversity, abundance and trap efficacy for class insecta at the lowland forest of Gunung Datuk, Negeri Sembilan / NurFatin Solehah Mohd Bustaman

A study on the abundance and diversity of nocturnal and diurnal insects was conducted at the lowland area of Gunung Datuk, Negeri Sembilan. This study also evaluates the effectiveness of different sampling traps Samples were collected from November 2014 to March 2015 using four different types of traps namely malaise, yellow-pan, pitfall and light traps A total number of 25 insects’ orders were recorded with the total individual of 4483. The most common order of insects found in this study was Hymenoptera (1479 individuals), Diptera (1279 individuals), Lepidoptera (210 individuals) and Coleoptera (159 individuals). The highest individual collected for malaise traps were Diptera (1028 individuals). Meanwhile, Hymenoptera recorded the highest individual for yellow-pan traps and pitfall traps with 307 and 963 individuals respectively. Light traps recorded Diptera as the highest individuals with 390. A total of21% of nocturnal insects and 79% of diurnal insects have been collected in this study. There is no significant interaction (P>0.05) on total individual collected and trap used in ‘his study. The highest diversity index is from light trap (H’=l.87) followed by yellow-pan trap (H‘= 1.86), malaise trap (H‘=1.29) and pitfall trap (H’=0.61). The H’ values are significant only for yellow-pan (P< 005) but not for other traps. Two-way ANOVA showed a significant difference (P<0.05) between all traps, Yellow-pan trap was found to be the most efficient for this study compared to the other traps.
