Abundance and Diversity of Fruit Flies Species (Diptera: Tephritidae) in Bogor and Depok District

Abstract

Fruit flies (Diptera: Tephritidae) are important pests of horticultural crops. This study investigates the abundance and species richness of Bogor and Depok District as a center area horticulture commodity based on Cue Lure Trap. Each Cue Lure Trap was observed to record the abundance and species richness of fruit flies at seven days intervals from June until August 2021 in Bogor District (Babakan, Mekarsari and Parigi Mekar) and Depok District (Bedahan and Pancoran Mas), West Java, Indonesia. A total of 1,025 individuals were collected and consist of nine species of fruit fly i.e., Bactrocera albistrigata, B. carambolae, B. neocognata, B. verbascifoliae, Dacus conopsoides, D. longicornis, Zeugodacus calumniata, Z. caudatus, and Z. cucurbitae. The number of individuals of fruit flies was highest in the Bedahan, Depok District (F = 5.454, P = 0.002). Zeugodacus cucurbitae was the most abundant species (792 individuals), representing 77.27% of the specimens collected during the sampling period. The highest Shannon–Wiener diversity index of all fruit flies captured in this study was in Bedahan, Depok (1.11) and the lowest in Parigi Mekar, Bogor (0.23). A Bray–Curtis analysis showed that the species compositions of fruit flies on Bedahan and Parigi Mekar had a similarity of 70.1%.

STRUKTUR KOMUNITAS LALAT BUAH (DIPTERA: TEPHRITIDAE) DAN TINGKAT SERANGAN PADA TANAMAN TOMAT (Solanum lycopersicum)

“…Menurut Tarno et al (2016), ketika nilai indeks diantara 0.5 dan 0.75, maka indeks dominansi lalat buah tergolong sedang. Nilai indeks dominansi lalat buah dari penelitian sebelumnya sebesar 70.1 sama dengan hasil penelitin ini (Octavia et al, 2021). Beberapa hal yang memengaruhi perbedaan keanekaragaman antara lain keanekaragaman inang, musim, keseimbangan lingkungan, distribusi spasial, kompetisi dan faktor kompleks lainnya (Gizachew, 2022) 2012), ada beberapa faktor yang dapat memengaruhi efektivitas insektisida dalam menyebabkan kematian serangga yang menjadi target.…”

Species composition of Bactrocera fruit flies (Diptera: Tephritidae) and their parasitoids on horticultural commodities in Batu City and Malang District, East Java, Indonesia

“…This insect group is a polyphagous pest on various fruits and vegetables. Many fruit commodities in Indonesia have been attacked by Bactrocera fruit flies, such as mango, citrus, papaya, guava, and chili (Abdullah et al 2021;Octavia et al 2021;Susanto et al 2022;Tarno et al 2022). Each species of Bactrocera fruit fly has a wide and different host plant.…”
