| Abstract | ||||
| For increasing and enhancing role of parasitoids as one of major elements in bio-controlling sugar beet insect pests. This trial was performed at Sakha, Agric. Res., Station and laboratory of Sugar Crops Res., Depart., Sakha- Kafr El-Sheikh Governorate. Results yielded that the parasitism efficiency for Opius nitidulator (Nees) (Hymenoptera: Braconidae) on Pegomyia mixta Vill. were 36.14% and 43.06% over the two successive seasons, 2022/23 and 2023/24, respectively. Meanwhile, the parasitism efficiency for Diadegma spp. Förster (Hymenoptera : Ichneumonidae) on Scrobipalpa ocellatella Boyd. were 46.43% and 62.50% during the two seasons, respectively. While, the parasitism efficiency for Microterys spp. Thomson (Hymenoptera : Encyrtidae) on Phenacoccus solenopsis Tinsley were 86.89% and 46.77% during two seasons, respectively. Moreover, Statistical analysis proved that high significant- positive correlation among previous insect pests and their associated parasitoids through the two seasons. Based on these findings, these parasitoids play an essential role for restraining insect pests. | ||||
