abstract
The study was conducted at peach, plum and pear plantation mixed with cucurbits during 2013 at Agricultural Research Institute Swat. The three food attractants, Methyl eugenol (ME), Nu Lure® (NL) and Cue-lure (CL) each comprised of 85% lures, 10% sugar and 5% insecticide (Diptrax 80-SP®) were applied in a plastic trap alone (one trap on a tree) or in combination where two or three traps of these attractants were installed. When single trap used, a distance of 24 meter was maintained while in case of two or three traps on a single tree a distance of 3 or 2 meters was maintained respectively. Each treatment was replicated three times and data were collected on weekly basis. Among the seven treatments, ME & CL baited traps installed on a single tree resulted a significantly higher number of fly catch (61.88) during the six weeks period followed by ME and NL baited traps installed in a single tree with 51.66 mean flies. ME, NL & CL baited traps installed in a single tree recorded 3rd in effectiveness with 47.83 mean number of flies for the whole season. While NL & CL baited traps resulted a significantly lowest number of flies (10.72) catch. Methyl eugenol baited traps installed as a single trap with 24 m distance with other traps resulted in 34.94 flies followed by CL with 26.06 flies while NL was the least effective treatment with 2.06 flies as seasonal mean. A total of 4215 flies were captured in the seven treatments. Bactrocera zonata was the dominant species followed by B. cucurbitae, B.dorsalis, B. diversa and B. tau.
