Regulatory mechanisms of reproduction in locusts and grasshoppers
New Plant Protection, EarlyView.Regulatory networks composed of numerous coding and noncoding genes play crucial roles in the reproduction of locusts and grasshoppers. This review integrates mechanistic advances in reproductive regulation, highlighting environmentally adaptive pathways and providing prospective targets for eco‐friendly pesticides.

New Plant Protection, EarlyView.Flight in female beet webworms (Loxostege sticticalis) promotes an increase in feeding, thereby enhancing abdominal energy reserves. Following flight, the flight muscles undergo accelerated histolysis, and the energy substances undergoing histolysis are redirected to the ovaries. These two processes collectively promote ovarian development.

Clinical and experimental obstetrics & gynecology, 1993 Several methods of facilitating the work schedule for in vitro fertilization programs have been proposed. LH-RH agonists offer the possibility of manipulating the day of hCG injection and consequently the day of ovum pick-up. Moreover, after desensitization, follicles are contemporarily stimulated and a higher number of mature oocytes are retrieved ...

Pest Management Science, EarlyView.Varroa destructor mites exposed to dsRNA specific in sequence to a V. destructor calmodulin gene significantly effected gene expression of adult female mites sampled 5 days after entering a honey bee brood cell to reproduce. Significantly down‐regulated genes included Calmodulin and were associated with calcium ion binding and embryo developmental ...
