The biology and economic importance of rice aphids (Hemiptera: Aphididae): a review.

Abstract

The biology and economic status of aphids attacking rice throughout the world is reviewed, as is the literature concerning other aphids found in or near irrigated rice fields but not usually infesting rice. Altogether, 37 species of aphids belonging to 17 genera are considered. The aphids are dealt with in two similar-sized groups according to their feeding sites, namely root-feeding and leaf-, stem- and ear-feeding species. Aphis craccivora Koch and Myzus persicae (Sulz.) are regarded as 'occasional rice aphids' as they are found on rice occasionally but do not regularly infest rice plants. A. gossypii Glov. is included as are data on 18 000 aphids trapped in yellow pan traps in Japan and on natural enemies reared from them.
