Abstract
The larvae of the rib miner,Scrobipalpa ocellatella Boyd feed on the sugar beet leaves and roots causing huge damage in such a way that the root rot and thus it caused a reduction in the yield of roots and the sugar content in the roots. Parasitoids are the most effective natural enemies for insect biological control. In nature, several parasitoids were observed to be potential bio-agents of serious crop pests. The future of "insecticide-less" pest management will be driven by a bouquet of parasitoids and predators complimented by entomopathogens. The reduction in insecticide residues in food - sugar beet is a food crop - is desirable for public health. The present study was carried out at the experimental farm of Sakha Agricultural Research Station, Kafr El-Sheikh Governorate-Egypt throughout two successive seasons 2018/2019 and 2019/2020. New parasitoid was recorded from the rib miner pupae. It was identified as Diadegma aegyptiator on S.ocellatella for the first time in Egypt. The Overall of parasitism were 24.52 and 31.03% in the two seasons, respectively. As well as, statistical analysis proved that a highly positive significant correlation coefficient values between S.ocellatella and its parasitoid in two seasons, respectively.These results elucidate that this parasitoid is a promising tool in reducing S.ocellatella populations.
