مطالعه میدانی اثر پاشش طعمه مسموم بر میزان جمعیت مگس میوه مدیترانه ای در باغی مخلوط در شهرستان تفت (استان یزد)

The Mediterranean fruit fly Ceratitis capitata is the most important species among Tephritidae family flies. The emergence of this pest in Yazd province after years then the expansion and increase of damage to garden products of the province, increased the necessity to control of it. Mass trapping is one of the most commonly used methods to control fruit fly. Protein hydrolysate is one of the oldest baits to tracking and mass trapping of Mediterranean fruit fly. In this study a mixed garden including armenian plum, common plum, cherry plum, cherries, figs and pomegranates were selected in a 40 days-period in the summer of 2017 in the central part of Taft city in Yazd. To estimate the population of the fly were used, the food attracting (CeraTrap) in the McPhail trap and male-attracting pheromone (Trimedlure) on Delta Trap in specified rows. Daily hunting information was recorded. After 10 days’ bait spray poisoning including protein hydrolyzate 3% and malathion .0.2% was carried out on sample trees in the garden. Immediately collected infected fruits on the trees and poured into the garden floor. The trap hunting results at the end of the 30-day period after the Bait spray was shown that the trap hunting rate in the garden decreased by 86.77%. This reduction in gardens without spraying and garden healthcare (Control garden) was 38.1%. The results of this study showed that the amount of Trimedlure Pheromone trap hunting was 63.17% higher than CeraTrap feed trap. Also, the non-specific hunting rate (non-target insects) in the pheromone trap containing Trimedlure 93.94% was lower than that of the CeraTrap food source. According to the results of this study, timely traceability, bait spray and garden healthcare can play important role in controlling and reducing the damage of Mediterranean fruit fly.
