Monitoring adult populations of Ceratitis capitata (Wied.), Rhagoletis cerasi (L.) (Diptera: Tephritidae), Drosophila suzukii (Matsumura), and Zaprionus Indians Gupta (Diptera: Drosophilidae) at different altitudes in fruit orchards of Adana Province in Türkiye

In recent years, fruit flies (Diptera: Drosophilidae and Tephritidae) have become an increasingly severe problem in fruit production in Turkey. Ceratitis capitata (Wied.), Rhagoletis cerasi (L.) (Diptera: Tephritidae), Drosophila suzukii (Matsumura), and Zaprionus indianus Gupta (Diptera: Drosophilidae) are the leading pests that cause worms in fruits. Using adult trapping, the population dynamics of these four pests were investigated in the orchards of Adana at different altitudes in 2019 and 2020. Rhagoletis cerasi adults emerged after the second week of May, and with the end of the harvest, the last adult emergence was seen in the first week of July. Adult population density was found at low levels. Drosophila suzukii adults appeared at 113 m (Balcal & imath;) in April, and their emergence times were observed to be a little later as the altitude increased. It was determined that they continued their existence in nature until the end of December. It has the highest populations in late June- mid-July and late October- November. The occurrence of C. capitata and Z. indianus adults in nature in both years was after cherry fruits were harvested. It has been observed that different orchards appear in direct proportion as the altitude increases (from 113 m to 1510 m), the earliest in a low altitude place and the longer their duration in nature.
