Abstract

The present study was designed to identify the peach fruit flies of genus Bactrocera species and to find out their percentage of abundance, relative humidity (%) and temperature (°c) in a district Dir lower of KPK, Pakistan. The data were collected by using sex pheromones traps i.e. Me-methyl eugenol and cl-cue lure to attract the flies in june, july and august, 2021. With the help of sex pheromones traps, specimens of flies were collected from 7-localities of Dir lower district including Adenzai, Balambat, Khall, Lal qilla, Munda, Samar bagh and Timergara on weekly basis. From the collected specimens, total six peach fruit flies were reported in Dir lower with the help of drew and romig, 2013 literature and their taxonomic keys by comparing with already identified specimens named as B. Zonata, B. Invadens, B. Cucurbitae, B. Dorsalis complex, B. Tau and B. Scutellaris in the Agriculture research institute Mingora Swat. Temperature (°c) and relative humidity (%) were also recorded on weekly basis to check their relation with the Bactrocera species abundance. In treatment #1 group of me-methyl eugenol traps, total number of Bactrocera species were identified is 18374 in 14 weeks study duration. In total number of Bactrocera species, the percentages and numbers were 10552 (57.428%) of B. Zonata, 5550 (30.205%) of B. Invadens, 95 (0.517%) of B. Cucurbitae, 5550(30.205%) of B. Invadens, 95(0.517%) of B. Cucurbitae, 2176(11.842%) of B. Dorsalis complex, 1(0.005%) of Bactrocera tau and Bactrocera scutellaris identified. In me-methyl eugenol traps, B. Zonata were reported maximum (57.428%) and B. Tau were minimum (0.005%). In treatment # 2 group of cl-cue lure traps, the total number of bactrocera species were identified is 1667 in 14 weeks study duration; in which the percentages and numbers were different such as 561 (33.653%) of B. Zonata, 205(12.297%) of B. Invadens, 793(47.570%) of B. Cucurbitae, 66(3.959%) of B. Dorsalis complex, 34(2.039%) of B. Tau and 2(0.01%) of B. Scutellaris. In cl-cue lure traps, B. cucurbitae were maximum (47.570%) and B. Tau were minimum (2.039%). The maximum number of species was reported at 23.1◦c with 80% humidity and minimum numbers were recorded at 37.8◦c with 32% humidity in me-methyl eugenol trap groups. In both trap groups, maximum number of species was reported at 23.1◦c with 80% humidity and minimum numbers were recorded at 37.8◦c with 32% humidity. This study proves that the efficacy of sex pheromone me-methyl eugenol is more than the cl-cue lure.
