Summary: The study aimed to enhance biological control measures for the serious pest Bagrada hilaris on brassica crops. By studying the egg parasitoid of B. hilaris found in Pakistan, it was found that the best combination of host egg and parasitoid age could be 0-1 day old host eggs with 3-10 day old parasitoids.

Summary: This study investigated the impact of parasitism by Cotesia vestalis on the gut microbiota of the host Plutella xylostella. The results revealed changes in the diversity and structure of the host-gut microbiota post-parasitization, with significant differences observed on the third day post parasitization. The study highlights the interaction between a parasitic wasp and gut bacteria in the host insect during parasitization.

Summary: The study found that extracts from the squash bug eggs significantly affected the host searching behavior of Gryon pennsylvanicum, leading to increased parasitism rates. Future research may lead to the development of synthetic lures to enhance parasitism by G. pennsylvanicum in squash fields, improving the efficacy of biological control.

Summary: This study investigates the impact of parasitism on host development and the regulation of insulin signaling pathway by parasitic wasps. The parasitization by Microplitis manilae drastically reduces the body weight, body length, and food consumption of the host, Spodoptera frugiperda. The gene expression analysis suggests that the parasitism leads to a significant decrease in insulin signaling pathway genes in the larvae of S. frugiperda.

Summary: This study examined the impact of extrinsic competition on host utilization and coexistence between two parasitoid species. The results showed that egg mass size was an important predictor of extrinsic competition, and reproductive traits of the parasitoid species contributed to their competitive advantage in different-sized egg masses. This study highlights the importance of considering extrinsic competitive interactions between parasitoid species in biological pest control.

Summary: Ooencyrtus mirus tends to oviposit on eggs of its primary host, Bagrada hilaris, regardless of the host species it was reared on. The preference for B. hilaris eggs is consistent among different parasitoid populations. Additionally, female wasps that emerge from B. hilaris eggs are smaller in size compared to those from T. pallidovirens and N. viridula eggs.

Summary: Parasitoid wasps, such as Leptopilina boulardi, manipulate nutrient amounts of their hosts through metabolic pathways like starch and sucrose metabolism, along with increased expression levels of carbohydrate and protein digestion genes in the host midgut post-parasitization. Additionally, immune genes related to Toll and Imd pathways also show high expression levels in parasitized hosts, indicating a complex interaction between parasitoid infection and host nutrient components.

Summary: We investigated the utility of cold-stored eggs of Glaucias subpunctatus for a field survey of Trissolcus japonicus. The results showed that the parasitism rate significantly decreased for 4 and 5 day-old host eggs. The storage temperature and period affected the parasitism rate, and adequate rates were confirmed in the field survey.

Summary: Despite the important implications for epidemiology, host age at parasites’ exposure is often neglected in studies on host-parasite interactions. In this study, we compared the impact of parasitic mite Varroa destructor and associated pathogenic virus DWV on different life stages of their host, the western honey bee Apis mellifera. The results showed that the pre-imaginal stages of honey bees are more susceptible to mite parasitization and viral infection than adults.

Summary: This study examines the dispersal distance and parasitism of the parasitoid O. agrili shortly after release, as well as the impact of host's food plants. The results show that there is no significant difference in observed parasitism by distance or tree species, but significantly more EAB eggs were parasitized in the longer deployment. These findings suggest that sentinel EAB eggs may be deployed on ash or white fringe trees to effectively monitor the establishment and spread of O. agrili.

Summary: This study looked into the effects of cold storage methods and host deprivation on the egg parasitoid Gryon gonikopalense, aiming to optimize its rearing process. It was found that storing bagrada bug eggs at 5 degrees Celsius resulted in higher parasitism rates and better progeny emergence, while different storage treatments did not affect the longevity and body lengths of male and female progeny. Additionally, host deprivation after 60 days caused a significant reduction in fecundity for the parasitoid.

Summary: Current entomological approaches for assessing host parasitization are either fast but destructive, or time-consuming. This study introduces the use of ultra-high frequency ultrasound technology as a non-invasive and effective method to evaluate the ability of parasitoids to parasitize soft-bodied hosts.
