Abstract
A field survey was carried out in West Bugwe Central Forest Reserve with the aim of determining the diversity and abundance of insect pollinators found in this forest reserve with comparison to those ones found at the forest edges. Sampling was done after two days for a period of one month viii using sweep nets, scan sampling and pan traps. Insects pollinators collected were sprayed with insecticides to immobilize them before pinning and dried in the cage. Representative specimen was taken to the biology laboratory for pinning and analyzing A total of 706 insect pollinators belonging to 11 families and 5 orders were recorded. The largest number of insect pollinators were recorded from order Lepidoptera (415), followed with order Hymenoptera (211), then order Diptera (35) followed by order Hemiptera (28) and lastly Coleoptera had the least number recorded with a total of 17 insect pollinators. Among these orders, only two orders were analyzed to family level that is Lepidoptera and Hymenoptera, under Lepidoptera, the family Nymphalidae showed the highest abundance 265(64%), followed by Pieridae 75(18%), Papilionadae 32(6%), Hesperidae 26(3%) with Rhiodinadae having the least number 5(1%). Under order Hymenoptera, family Apidae had the most abundant number 147(82%) followed by Vespidae 17(9%) Megachilidae 5(3%), Colletidae 4(2%) and Halictidae (1%) recorded the lowest relative abundance. The highest species diversity was observed in the order Lepidoptera (H’ =1.1107), while orders Hemiptera and coleopteran had the least (H’=0). However, the habitat with the highest species evenness was the forest interior (0.5658). This information shows that West Bugwe Central Forest Reserve is an ecosystem hotspot for abundance and diversity of insect pollinators and therefore it should be conserved by the stakeholders and concerned bodies for the continued ecosystem health.
