Abstract
The current study was conducted in Qaleen city Kafr El Sheikh governorate during 2022/23 and 2023/24 seasons. The larval population density of the leaf miner, Liriomyza huidobrensis (Blanchard) was affected by parasitoids and other abiotic. The highest peaks of healthy larvae were recorded in the third week of December 2022 and in the second week of January 2024 with 47and 66 larvae/100 leaflets during the first and second seasons respectively. Meanwhile, the parasitoid , Diglyphus isaea (Walker) activity increased and recorded the highest peaks in the 1st weeks of February 2023 and March 2024 with 39 and 40 individual during the first and the second seasons, respectively. The unknown dead larvae recorded the highest peak in 2nd week of February 2023 and 4th week of January 2024with 36 and 42 individual respectively. The highest peaks of total larvae were recorded in the 2nd week of February 2023 with 70 larvae/100leaflets during season 2022-2023 and in the 2nd and 4th weeks in January 2024 with103 larvae/100 leaflets during season 2023-2024. The rate of parasitism recorded the highest average in January by 53.7% in the first season and 50.67% in March in the second season. While the highest unknown dead larvae percentages were 37.45% and 44% in February for the first and season respectively.
