Egg Parasitoid of Small Brown Planthopper, Laodelphax striatellus FALLÉN (Hemiptera: Delphacidae) in Hokkaido, Japan

Abstract

Anagrus flaveolus, a mymarid egg parasitoid of the small brown planthopper was found in paddy fields in Hokkaido, Japan. The percent parasitism measured by the “trap method” was high (66%-96%) in all the paddy fields from late June to early August, and the egg parasitoid seemed to be an important natural enemy of the planthopper.
