Mosquito Diversity between Logged a nd Unlogged Forest Areas i n Kalabakan Forest Reserve , Sabah

Mosquitoes were sampledin an undisturbed area within the trail in the forest nearthe Maliau Basin Conservation Area (MBCA) and in a disturbed area within the LoggedForest Experimental (LFE) area near the SAFE Project camp site . A total of 48 day s ofsampling was done in both a reas in a bi monthly sampling starting June 2016 to April2017. The aims of this study were to investigate the species diversity and peak bitinghours of mosquitoes in both sites. A total of 807 individuals from 17 species werecaught using manual collection method of Human Landing Catch (HLC). 15 specieswere collecte d in MBCA while only 9 species were collected in LFE Based onGeneralized Linear Mixed Model (GLMM), there was a significant difference ofmosquito abundance between LFE and MBCA (p 0.05) and mosquito day biting time(p 0.05). Also, based on Independent T test analysis, there was a significancedifference in term s of mosquito diversity level and abundance (p 0.05) In this study,LFE had higher mosquito abundance with a total of 563 mosquito individuals caughtcompared to MBCA with 244 mosqu ito individuals. In both areas, more species wererecorded during day time samplings than night time samplings. Anophelesbalabacensis , Aedes albopictus , Heizmannia scintillans and Culex vishnui wereamong the predominant species collected in LFE while in MBCA species collectedwere Heizmannia scintillans , Anopheles umbrosus , Aedes albopictus and Armigeresjugraensis . LFE had peak biting hours around 2:00 p.m., 5:00 p.m., 7.00 p.m. and9:00 p.m. while for MBCA, the peak biting hours were between 2:00 3:00 p.m. and6.00 p.m.
