The Diversity of Fruit Fly (Diptera: Tephritidae) on Combination of Attractant and Different Trap Height in Cucumber Field (Cucumis sativus L.)

The main pest in the Cucurbitaceae family is the fruit fly. The common effort to control fruit flies is using a trap with methyl eugenol (ME) and cue lure (CUE) as an insect attractant. The trap height installation is also affecting the fruit fly population. The fruit fly population in the field has an important effect on the damage intensity in the commodity. This research objective was to study the distribution and diversity of fruit fly on the cucumber field with trap height installation and attractant combination. The used research method was Factorial Group Randomized Design (RAKF). The first factor was attractant combination of Metil Eugenol (ME) and Cue Lure (CUE) consisted of 6 treatment levels were K1 : 5 mL ME, K2: 5 mL ME + 1 mL CUE, K3: 5 mL ME + 3 mL CUE, K4: 5 mL ME + 5 mL CUE, K5: 5 mL ME + 7 mL CUE and K6 : 5 mL CUE. While the second factor was the high tramp installation consisted of 3 treatment levels were T1: 50 cm, T2: 100 cm, and T3: 150 cm. The treatment consisted of 3 replication on three different cucumber fields. The result showed discovered fruit fly species were eight species, B. dorsalis (Hendel), B. carambolae Drew & Hancock, B. occipitalis (Bezzi), Z. caudata (Fabricius), B. umbrosa (Fabricius), B. neocognata Drew & Hancock, Z. cucurbitae (Fabricius) and B. albistrigata (de meijere). The dominant fruit fly in each treatment in fruit fly fields was B. dorsalis (Hendel). The best treatment in trapping fruit fly was K1 (5 mL ME) with trap height installation T1 (50 cm). The diversity and species richness of fruit fly in the cucumber field was considered low and uneven.
