The objective of this study is to analyze composition of insect visitors in canopy of apple trees in correlation with environmental factors in Poncokusomo (Malang) and in Bumiaji (Batu), East Java. This research was conducted on July to October 2011. The insects were observed by visual observation conducted on 5 apple trees. Those observation efforts were repeated four times in flowering season and fruiting season of the apple respectively. Overall, 2258 individuals were observed visually in Malang and 485 individuals were found in Batu. Pompilidae, Dolichopodidae, and Culicidae were dominant in the samples from Poncokusumo, Malang composing about 44% individual in flowering season, and 55% in fruiting season. Whereas, Drosophilidae, Ichneumonidae and Syrphidae were dominant in Bumiaji samples composing about 63% individual in flowering season and 88% in fruiting season. This study indicates the abundance and diversity of insect visitors to apple canopy in Malang were higher than those in Batu. The composition of insect visitors in apple crop is affected by study site and seasonal flowering phenology. The abundance and diversity of insect visitors were greater in flowering season in both locations. The peak of insect visitor abundance occurred in the morning, mostly during second period (09.00-10.15).
