Soybean Insects Occurring at Podding Stage in Taichung

A survey of insect pests infesting soybean at the podding stage was carried out at Wufeng in Taichung in 1979. 7 orders, 16 families and 33 species of insect pests were found attacking this crop. Among them, 10 species, viz, Halticus tibialis, Cletus trigonus, Riptortus clavatus, Cletus punctiger, Nezara viridula, Piezodorus hybneri, Eysarcoris guttiger, Aphis glycines, Etiella zinckenella, Spodoptera litura, attacked the pods. Nezara viridula and Etiella zinckenella are recognized as the most serious pests. The damage and the economic importance of other soybean insect pests are also discussed in this paper. Research on soybean insect pests in Taiwan has always been focused on leaf-mining insects, such as Ophiomyia phaseoli, Melanagromyza sojae(3,5,7,8,9), or pests ’ chemical control(1,2,4,10,11,12)?but surveys on insect pests species are rare, and related information or data is serious lacking. In fact, soybeans can be attacked by many species of insect pests from the young seedling to mature stages, and the species of insect pests involved are quite complex. At the same time, the long soybean podding stage, which takes about a half of the whole growing period of soybeans, make it possible for insects to harm pods directly or influence pod development by attacking other parts of soybean plants. This paper introduces results from a preliminary survey on the species of soybean insect pests found during the podding stage, with the purpose of assisting pest control by clarifying insect species. Due to the relatively short time of the survey, the insect pests collected in this paper are just a portion of all soybean insect pests involved.Originating text in Chinese.Citation: Wang, Chin-Ling.
