Bactrocera yang menyerang jambu air yaitu Bactrocera ablistrigta, Bactrocera carambolae menyerang belimbing dan jambu biji, Bactrocera mcgregori menyerang melinjo dan Bactrocera papayae menyerang mangga. Kelimpahan Bactrocera albistrigata sebesar 112 individu/kg jambu air, Bactrocera carambolae pada belimbing sebesar 368 individu/kg belimbing, Bactrocera carambolae pada jambu biji sebesar 86 individu/kg jambu biji, Bactrocera papayae sebesar 48/kg mangga dan Bactrocera mcgregogi sebesar 668 individu/kg melinjo. Kelimpahan tertinggi terdapat pada Bactrocera mcgregogi yaitu 668 individu/kg melinjo.
