A preliminary study of insect abundance on West Island, Aldabra Atoll, Indian Ocean


, : A preliminary study of insect abundance on West Island, Aldabra Atoll, Indian Ocean. Ecological Entomology 127(3): 209-225

1Heath and Rothamsted light traps and a Johnson-Taylor suction trap were used to sample flying insects on Aldabra Atoll.2The present study extended over two wet seasons. The pattern of relative monthly insect activity resembled the rainfall pattern. Catches were greatest during the months when there was a sudden marked increase in precipitation.3Lepidoptera dominated light trap catches and Diptera suction trap catches, the total monthly insect numbers therefore reflecting the abundance of these two orders. Hemiptera, Coleoptera and Hymenoptera were also common.4Predominant families were represented by only a few or even only one dominant species. These species were present throughout the study period although their monthly totals varied considerably, different species dominating the catches during different months.5The composition and size of catches in the three light traps was affected by the type of light source and surrounding vegetation.6A comprehensive list of families and selected common species is given with their relative monthly abundance in the light traps.7Suction trap catches were segregated on an hourly basis to give a broad indication of insect flight periodicity.
