AbstractOviposition and post-oviposition behavior of Telenomus fariai Costa Lima, when parasitizing the eggs of Triatoma phillosoma pallidipennis Stål, is described. Like other egg parasites T. fariai marks hosts by rubbing the ovipositor against the host and transferring a water soluble pheromone (chemical nature unknown) to its surface. Females that had never parasitized largely ignored the mark. Females that had parasitized generally did not oviposit on a marked host. The mark was fully effective for at least 3 days after being applied. The function of egg marking by T. fariai is discussed.

First Time

We report for the first time the parasitism of eggs of two triatomine Chagas disease vectors,Triatoma infestansandT. vitticeps, by the microhymenopterous parasitoidAprostocetus asthenogmus. We also describe the first identification of this parasitoid in South America.A. asthenogmuswere captured near unparasitized triatomine colonies in the municipality of Vitória, state of Espírito Santo, Brazil, and placed into pots with recently laid triatomine eggs. After 24 days, we observed wasps emerging fromT. infestansandT. vitticepseggs. Several characteristics of this parasitoid species suggest that it could be a potential biological control agent of triatomine species.
