Última Effect of Wolbachia on the Survival and Reproduction of Trichogramma kaykai Pinto & Stouthamer (Hymenoptera: Trichogrammatidae) Neotropical Entomology HOHMANN,CELSO L.; LUCK,ROBERT F.; STOUTHAMER,RICHARD. Parthenogenetic inducing Wolbachia infections are particularly common in the genus Trichogramma, but the influence of the microrganism on parasitoids' fitness has received relatively little attention. The aim of this study was to determine the effects of the bacteria on the survival and reproduction of Trichogramma kaykai Pinto & Stouthamer, comparing an infected line (thelytokous) with an antibiotically cured (arrhenotokous) line, both reared on Trichoplusia ni Hübner eggs. Cured wasps produced significantly more progeny and more daughters than Wolbachia-infected wasps. Significantly more wasps emerged per host when parasitized by the arrhenotokous females than by the thelytokous females. Cured females, however, lived significantly less than...

The effect of temporary host deprivation on the reproduction and survival of Trichogramma kaykai Pinto & Stouthamer was determined by comparing a Wolbachia-infected (thelytokous) and an arrhenotokous line of T. kaykai when reared on Trichoplusia ni Hübner (Lepidoptera: Noctuidae) eggs. The progeny produced by both arrhenotokous and thelytokous females decreased with increasing periods of host deprivation, but arrhenotokous females produced significantly more progeny than thelytokous females regardless of the period of host deprivation (0 to 10 days). They also produced more daughters. Host deprivation did not affect brood size within arrhenotokous or thelytokous lines. However, fewer wasps emerged from hosts parasitized by Wolbachia-infected than...
