Abstract:

Auchenorrhyncha (Hemiptera) contain some of the economically important agricultural pests worldwide, including many invasive ones. The great diversity of some auchenorrhynchan families such as leafhoppers (Cicadellidae) and planthoppers (Delphacidae) corresponds to at least an equal, but often even greater diversity of their natural enemies, particularly egg parasitoids. Whereas during the past 100 years scientists were able to properly identify and study most of the major and some minor auchenorrhynchan pests, research on their egg parasitoids, which are mainly responsible for their natural control, either has been lagging behind significantly or outright nonexistent. Recent developments in the identification of egg parasitoids (Hymenoptera: Mymaridae and Trichogrammatidae) in the four economically important agroecosystems of rice, grapevines, okra, and tea in East Asia are reviewed, along with their host associations, many of which being either newly established, updated, or corrected.
