Abstract

The seasonal abundance and population density of emerged moths of Synanthedon myopaeformis Borkh. (Lepidoptera : Sesiidae) from infested apple trees at Berket El Saba district, Menoufia governorate during 2015 and 2016 years exhibited that the emerged moths continued all year round where, nine emergence peaks were recorded throughout year months. The highest number of emerged moths was observed during the summer months (40.96% and 41.26% at 2015 and 2016 seasons, respectively) and the highest monthly percentage of emerged moths was recorded in August. The highest number of emerged moths were recorded at the basic stem region 0-50cm above the ground surface, while the least number of emerged moths was found at the height 150-200cm and there was significant positive correlation between minimum & maximum temperatures and number of emerged moths, while the correlation was negative between RH% and number of emerged moths. The obtained results indicated that the minimum & maximum temperatures and RH% were responsible for 71.67% and 73.71% of changes population during the successive periods at 2015 and 2016, respectively.
