Abstract
Insect communities were documented across six (6) commercial Balsa plantations in East New Britain Province of Papua New Guinea. Gilalum recorded mostly Coleopterans (50%) while very few Hymenopterans (16.7%), Lepidopterans (16.7%), Orthopterans (16.7%) and Odonata (16.7%). Lepidopterans were common in Kaingaski (55.6%) when compared to other taxa. There were more lepidopterans (58.8%) in Klinwata plantation than other taxa while 23.5% consisted of Orthopterans. Laup plantation had 35.7% lepidopterans, 21.4% hymenopterans, 21.4% odonatans, 14.3% coleopterans and 7.1% orthopterans. Putput had a good representation of lepidopterans (56.2%) followed by coleopterans (28.1%) and orthopterans (9.4%). Putput plantation was the most diverse site having a total of 32 species which were uniformly distributed (H=2.66, E=0.77). Tanao had the second highest diversity with species richness of 19 which were evenly distributed within the site (H=2.37, E=0.81). Laup plantation had the third highest diversity of 14 species with uniform distribution (H=1.93, E=0.73). Klinwata followed with total of 17 species that were less uniform in their distribution within the plantation (H=1.72, E=0.61). Gilalum recorded 6 species that were not uniformly distributed within the plantation (H=0.93, E=0.52). Kaingaski plantation had the lowest diversity with 9 species that were poorly distributed within the study site (H=0.79, E=0.36). From the aforementioned results, we concluded that a plantation with vegetation heterogeneity, complex undergrowth, low anthropogenic disturbances, long-standing trees, strict conservation guidelines and effective monitoring is paramount to enhance species richness of insects
