Diversity of Bactrocera spp. on some mango varieties at Kecamatan Talun, Kabupaten Cirebon

Abstract

Fruit fly (Bactrocera spp.) is a major pest of horticultural crops, especially fruits. Fruit fly larvae feed on the flesh of fruit, and cause the decrease of both quantity and quality of the production. Fruit fly species on certain fruit in an area is important to be identified to make a right decision in choosing the control methods. The objectives of this study were to identify the fruit fly species, and determine the dominant species and diversity index of fruit flies on mangoes Gedong Gincu, Cengkir, and Arumanis at Kecamatan Talun, Kabupaten Cirebon, Indonesia. The survey was carried out by collecting samples of mango fruit attacked by fruit flies from field, wholesaler, and retailer at Kecamatan Talun. The results showed that there were four species that attack mangoes Gedong Gincu, Cengkir, and Arumanis at Kecamatan Talun, namely B. dorsalis; B. carambolae; interspesific hybrids of B. carambolae and B. dorsalis; and B. albistrigata. The dominant species was B. dorsalis. Diversity index (H') of fruit fly species was 0,05 ≤ H' ≤ 0,48 (H' < 1,5), so that the diversity was considered low.
