Abstract: A survey of insect pests of Mangifera indica plantation was conducted between July 2006 and March 2007 in Chuping, Perlis, Malaysia. Day sampling and night observations (with light traps) was carried out to observe the presence of insects on leaves, flowers, fruits and branches of the mango tree. Nine orders of insects belonging to 45 families were observed and this includes Coleoptera, Demaptera, Diptera, Hemiptera, Homoptera, Hymenoptera, Lepidoptera, Odonata and Orthoptera. Coleoptera was the most abundant (Margalef index: 4.446) of which 680 belonging to 30 species and 12 families were collected throughout the period of study. Diptera was the most specious (Simpson Diversity index, 0.89). The result of field study showed that during the non-fruiting season 165 individuals of Monolepta bifasciata was recorded probably due to the presence of many young mango shoots during the season. Six adults of R. simulans were also observed in fruiting season including a mating pair. The implications of these results are discussed in relation to the management of insect pests of mango plantation in Malaysia.
