Notes on the Ovipositional Behavior of Trichogramma fuentesi (Hymenoptera: Trichogrammatidae), an Egg Parasitoid of Cactoblastis cactorum (Lepidoptera: Pyralidae)

Our study characterized host searching and oviposition ability of T. fuentesi. In general, female wasps walked to a C. cactorum egg, drummed over the surface, drilled into the chorion, and deposited an egg. Grooming and resting behaviors were observed infrequently and host feeding was never recorded...

Description
Summary:Our study characterized host searching and oviposition ability of T. fuentesi. In general, female wasps walked to a C. cactorum egg, drummed over the surface, drilled into the chorion, and deposited an egg. Grooming and resting behaviors were observed infrequently and host feeding was never recorded. In a typical observation period of 60 min with eggs of the exotic C. cactorum, female parasitoids spent 16% of their time drumming, 4% drilling, and 8% egg laying into the selected host. Most of the oviposition behaviors happened in the first hour.
