Life Cycle of the Soybean Aphid Aphis glycines Matsumura, in Japan

摘要: The soybean aphid Aphis glycines MATSUMURA is the main sap-sucking pest on soybeans Glycine max. In Japan, it distributed from Hokkaido to Kyushu (Sakai, 1949); abroad, found in Korea, China, Taiwan, Thailand, Malay (Paik, 1965), Phillipines (Takahashi, 1966), and India (Raychaudhuri et al., 1980). addition soybeans, wild species are known be a secondary host. Matsumura reported this (1917a) same year recorded that its eggs over-wintered plants belonging pea family (1917b). Shindo (1928, 1932) originally identified Kitsunenomago Justicia procumbens purplish amaranth Amaranthus blitum as primary hosts, but later retracted over-winter roots of Japanese chaff flower Acyranthes japonica (1941). However, Sakai (1949, 1950a, b) showed greenhouse studies does not flower, concluded was actually justiciae SHINJI which (1928) considered glycines. While controversy Japan about host remained unresolved, China by Wang al. (1962) Dahurian buckthorn Rhamnus davurica family. Zhang Zhong (1982) subsequently established several 15 genus were hosts. reports only body color number sensilla third antennal segment gynopara reported, no mention made morphs Since 1981, our field surveys have focused life cycle hosts Rhamnus, results here.
