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