بررسی مقدماتی تاثیر سرکه ی چوب و دود مایع روی مگس جالیز، Dacus ciliatus Loew (Dip.: Tephritidae)

The cucurbite fly, Dacus ciliatus (Loew), are one of the most important pests in Iran and the world, which is being annually sprayed against it. The most commonly used pest control method in the country is chemical control. Farmers often spray their fields at different times with different types of pesticides, and in some cases dangerously dangerous pesticides, often without regard to the life cycle of the pest, the period of pesticide use, and the harvesting time of harvested products that are often consumed freshly. In the present study, with a view to studying repellent compounds, the application of liquid smoke (1, 5 & 10% concentration), typical wood vinegar (5000 & 10000 ppm) and distilled wood vinegar (1500 & 3000 ppm), dimethoate insecticide (1500 ppm) were tested in the melon farm of Kashmar region, during 2017. The research was conducted in a randomized complete block design with 9 treatments and 4 replications. Three times the application was carried out at intervals of 2 weeks and the infected fruits were counted during the season and at harvest time, and the infection rate and repellency of the treatments were calculated. Based on the field studies, The highest and the lowest infection rate were in control treatment and spraying with distilled wood vinegar treatment (3000 ppm), respectively. Also, the infection rate in spraying with distilled wood vinegar, typical wood vinegar and liquid smoke, dimethoate insecticide and control treatments were 19.4, 21.4, 52.7, 85.5 and 97.7%, respectively, and the repellency of pest in spraying with distilled wood vinegar, typical wood vinegar and liquid smoke and dimethoate insecticide treatments were 66.8, 58.4, 29.9 and 6.7%, respectively. Therefore, according to the results, wood vinegar can be effective for reducing cucurbit fly damage.
