Pseudogonatopus
Pseudogonatopus is a genus of dryinid wasps established by Perkins in 1905. Species in this genus are parasitoids of planthoppers (Hemiptera: Delphacidae), particularly Nilaparvata lugens (brown planthopper), a major rice pest in Asia. The genus exhibits sexual dimorphism: females are wingless with ant-like morphology, while males are winged. Members possess strong mandibles used for host feeding. The genus has been studied extensively for its role in biological control of rice planthoppers and for assessing non-target effects of transgenic Bt rice.
