Última Effect of temperature on the development and thermal requirements of Wolbachia-infected and antibiotically cured Trichogramma kaykai Pinto and Stouthamer (Hymenoptera: Trichogrammatidae) Anais da SEB Hohmann,Celso L.; Luck,Robert F.. The development times and the thermal requirements of Wolbachia-infected and antibiotically cured Trichogramma kaykai Pinto and Stouthamer (Hymenoptera: Trichogrammatidae), using Trichoplusia ni Hübner (Lepidoptera: Noctuidae) eggs, were assessed at four constant temperatures (15, 20, 25, and 30°C), 70 ± 5% RH, photophase 14 h. The knowledge of temperature effects are very important in helping understand the dynamics of desert organisms like T. kaykai that face extreme temperatures during the season. Cured wasps developed faster at higher temperatures (20, 25, and 30°C) than infected wasps. However, infected wasps developed faster at the lowest temperature (15°C) than cured wasps. Developmental times of cured and infected wasps increased from 7.0 and 7.1... Tipo: Info:eu-repo/semantics/article Palavras-chave: Insecta; Parasitoids; Temperature; Parthenogenetic induced bacteria.

Experiments were conducted to determine whether Trichogramma platneri Nagarkatti manifested a somatic-gametic trade-off and whether it was affected by host availability and host size. Large wasps produced on Trichoplusia ni Hübner and limited to five or 15 T. ni eggs daily, produced a similar number of progeny as wasps offered hosts from emergence. Similar results were obtained when they were deprived of T. ni eggs for one, three, five, or ten days and then provided with unlimited hosts daily until death. In contrast, small wasps produced from Sitotroga cerealella (Olivier) and deprived of T. ni eggs for one to three days suffered a significant reduction in progeny production. Regardless of size, the egg load of non-ovipositing wasps increased... Tipo: Info:eu-repo/semantics/article Palavras-chave: Biological control; Somatic-gametic trade-off; Reproductive success.
