Host Deprivation Effect on Reproduction and Survival of Wolbachia-Infected and Uninfected Trichogramma kaykai Pinto & Stouthamer (Hymenoptera: Trichogrammatidae) Neotropical Entomology
HOHMANN,CELSO L.; LUCK,ROBERT F.; STOUTHAMER,RICHARD.
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...
