| Abstract | ||||
| The highest average number of the total number of the sugar beet moth, Scrobipalpa ocellatella larvae and the highest average number of the healthy larvae were recorded in October plantation and presented by 20.1±1.75 and 14.4±1.68 individuals On the other hand, the average number of the parasitized larvae caused by Agathis sp. was ranged between 0.3±0.33 individuals in September plantation and 0.8±0.24 individuals in November plantation during the first season, 2018/19. while in the second season 2019/20, the highest average number of the total S. ocellatella larvae and the highest average number of the healthy larvae were recorded in August plantation and presented by 14.4±2.01 and 9.4±2.29 individuals On the other hand, the average number of the parasitized larvae caused by Agathis sp. was ranged between 1.0±0.58 individuals in September plantation and 1.6±0.40 indiv.in August plantation. The percentage of parasitism caused by the larval parasitoid, Agathis sp. was the highest in August plantation during the first season and in October plantation during the second season and presented by 7.5 and 17.7%, respectively. The highest average number of the total S. ocellatella pupae and the highest average number of emerged moth were recorded in October plantation and represented by 17.3±1.72 and 14.4±1.68 individuals Furthermore, the average number of parasitized pupae caused by Diadegma sp. was ranged between 0.6±0.24 individuals in August plantation and 2.5±0.42 individuals in October plantation in the first season. While in the second season, the highest average number of the total S. ocellatella pupae and the highest average number of emerged moth were recorded in August plantation and represented by 11.2±1.93 and 9.4±2.29 individuals | ||||
