Haplogonatopus hernandezae (Hymenoptera: Dryinidae) parasitizing the rice planthopper Tagosodes orizicolus (Hemiptera: Delphacidae) in Central-Western Brazil

Haplogonatopus hernandezae Olmi (Hymenoptera: Dryinidae) was detected in an experimental rice plantation area. This is the first record of parasitism by H. hernandezae of the rice planthopper, Tagosodes orizicolus Müir (Hemiptera: Delphacidae), in Brazil. The average duration of the pupal stage was 10.6 ± 0.15 days. Adults kept in test tubes and fed with honey and vitamin E had the greatest longevity. In a second experiment, adults kept on rice plants and fed with honey had the greatest longevity. Adults kept on rice plants lived longer than adults kept in test tubes when fed on honey alone. This record represents an important finding for Brazilian rice agriculture because it directs research for the application of H. hernandezae as a biological control agent.
