Determination of Seasonal Activity of the Sweetpotato Whitefly (Homoptera: Aleyrodidae) and Leafhoppers (Homoptera: Cicadellidae) by Plastic Cup Traps on the Cukurova Plain, Turkey

摘要

The flight activities of adult sweetpotato whitefly, Bemisia tabaci, and leafhoppers were monitored by plastic cup traps at Bogah, Tasci, Haciali, Dogankent and Balcah in the Cukurova Plain, Turkey, in 2001 and 2003. Activity of B tahací, expressed as numbers of adults caught in traps, was low from May to early July in both years. Numbers of B. tabaci caught at Tasci were higher than at Bogah from 10 July and 21 August in 2001. Its numbers were also higher at Dogankent than at Haciali and Balcah during August of 2003. The numbers of leafhopper adults caught fluctuated greatly in both years. Numbers remained low until late June, followed by gradual increases in July and August at Bogah and Tasci in 2001. In contrast, numbers of adults caught were higher at Haciali, Dogankent and Balcah from May through July in 2003, followed by lower catches during the remainder of the season. Daily minimum temperatures in July and August were positively correlated with higher trap catches of both B. tabaci and leafhoppers.
