Abstract
Afield study was carried out at the experimental farm of Sakha Agricultural Research station , Kafr El-Sheikh, Egypt during two seasons 2015/2016 and 2016/2017. The highest peak of abundance ofL. huidobrensis total larvae on Pisum sativum plants recorded in the third week of December 2015 and represented by 62 larvae /100 leaflets. The highest peak for healthy larvae found in the third week of March 2016 and represented by 51 larvae. While the highest peak of abundance for the parasitized L. huidobrensis larvae by D. isaea found in the second week of January 2016 and represented by16 larvae. and unknown larval mortality recorded in the fourth week of December 2015 and represented by 11 larvae. The average number of the total larvae, healthy larvae, parasitized larvae by D. iseae and unknown larval mortality were recorded with an average of 27.3 ±1.7, 30.4 ±1.7, 4.1 ±0.11 and 3.5 ±0.6 larvae, respectively. The average percentage of the healthy larvae recorded 73.3% and the average percentage of parasitism caused by D. isaea was 14.5% while, the percentage of unknown larval mortality recorded 9.6% during the first season 2015/16. The highest peak of abundance ofL. huidobrensis total larvae on Pisum sativum plants recorded in the second week of January 2017 and represented by 70 larvae /100 leaflets. The highest peak for healthy larvae found in the third week of December 2016 and represented by 41 larvae. While the highest peak of abundance for the parasitized L. huidobrensis larvae by D. isaea found in the second week of January and represented by 16 larvae. and unknown larval mortality recorded in the second week of January 2017 and represented by 21 larvae. The monthly average number of the total larvae, healthy larvae, parasitized larvae by D. iseae un known larval mortality were recorded with an average 28, 18.4, 2.9 and 6.6, respectively. The average percentage of the healthy larvae recorded 76.2% and the average percentage of parasitism caused by D. isaea was 6.6% while, the percentage of unknown larval mortality recorded 17.3% during the second season 2016/17.
