Abstract
These experiments were carried out in Lakana and Sharnub villages, El-Beheira Governorate, during the 2017, 2018, and 2019 seasons to study the crop type, regional and seasonal effects on male adults of S. littoralis caught by YWPT. The average numbers of moth, for sugarbeet, clovers and wheat were 7.57, 9.00, and 5.64 respectively, at Lakana village, and were 11.19, 10.70, and 8.77 respectively, at Sharnub village in winter crop fields during the 2017/2018 season. While during the 2018/2019 winter season, the average numbers of moth, were 13.95, 10.65, and 8.05 respectively, at Lakana village, and were 15.33, 10.38, and 13.18 respectively, at Sharnub village. Comparing moth numbers catches significant differences were noticed between the crops, where the average moth for sugarbeet higher than clovers and wheat.
The average numbers of moths, for soybean, maize and cotton were 61.00, 15.27, and 70.50 respectively, at Lakana village, where it was 74.23, 23.80, and 87.80 respectively, at Sharnub village in the 2018 summer season. During the 2019 summer season, the average numbers of moths, were 63.05, 24.40, and 75.10 respectively, at Lakana village, and were 71.29, 28.13, and 103.40 respectively, at Sharnub village. However, moth numbers catch significant differences were noticed between the crops, where the average moth for cotton and soybean higher than maize.
