“…These results are agree with Bazazo and Ibrahim (2019) in Egypt, found new parasitoids of the sugar beet moth S. ocellatella in the Egyptian environment and evaluated its effectiveness in reducing the population of the pest during three successive seasons. In 2016/17, 2017/18 seasons, new parasitoid was recorded from the beet moth pupae.…”

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

“…They play an important role in reducing S. ocellatella .infestations. Bazazo and Ibrahim (2019) indicated that the mean of parasitism by D. oranginator were; 55.17, 60.46 and 68.91% at the three cultivations, respectively. In Britain sugar beet fields, Pitkin et al (2019) emphasized four species parasitoids on S. ocellatella; Copidosoma filicorne (Dalman) (Hymenoptera : Encyrtidae) , Agathis fuscipennis (zetlerstedt), Therophilus mediator (Nees), Orgilus pimpinellae Niezabitowski (Hymenoptera : Braconidae).…”

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.
