Acta Entomologica Sinica 41 (1), 41-47
Abstract: This paper deals with the relative abundance, parasitization and preference of egg parasitoids of rice planthoppers in both rice and surrounding non-rice habitats. 4 species of egg parasitoids, Anagrus flaveolus, A. optabilis, Oligosita aesopi and O. naias are collected from rice and non-rice habitats, however, A. flaveolus is the dominant one. Egg parasitoids from various habitats have different characterisitics of parasitization and preference to host eggs. A. flaveolus could normally parasitize an alternate host within Delphacidae family, but usually needs 1~2 generations for host adaptation. O. aesopi is greatly affected by host eggs belonging to the family Delphacidae or Cicadellidae. A. flaveolus trapped from rice fields significantly prefer rice planthopper Nilaparvata lugens and Sogatella furcifera to non-rice planthopper, Togosodes pusanus. However, A. flaveolus trapped from grassy area choose T. pusanus eggs rather than rice phanthoppers. The non-rice habitats play an important role in conserving egg parasitoids of rice planthoppers.
