Abstract

A survey of the parasites of the small white butterfly, Artogeia rapae (L.) in China.

Abstract

A survey was conducted in China in 1978-82 on the parasites of the crucifer pest Artogeia rapae (L.). The parasites were reared from over 193 000 eggs, larvae and pupae collected in 21 provinces, municipalities and autonomous regions. A total of 12 species of primary parasites was found; these were Trichogramma evanescens Westw., T. chilonis Ishii (confusum Viggiani), Apanteles glomeratus (L.), A. rubecula Marshall, Hyposoter sp., Pteromalus puparum (L.), Brachymeria lasus (Wlk.), B. femorata (Panz.), Pimpla disparis Vier. (Coccygomimus disparis), Exorista sorbillans (Wied.), E. amoena Mesnil and Phryxe vulgaris (Fall.). Percentage parasitism of eggs, larvae and pupae was 0-1.7, 0-64.5 and 0-97.0, respectively. The protection and utilisation of some of the parasites in different parts of China are discussed.
