摘要
研究表明：一年之中，桃瘤头蚜发生１２～１４代。各代平均发育期：干母１７天，干雌１２天，春季迁移蚜１５天，性母２２天，性蚜２７天。秋季从夏寄主迁返桃树的有翅蚜即为性母，在桃树上产雌雄性蚜，支配产卵越冬。桃瘤头蚜最适温度范围为１５～２３℃。营养条件是影响桃瘤头蚜田间数量及分化的关键因素。在防治方法方面，测定了６种药剂治蚜的药效，以氧化乐果和甲甲磷为好；防治桃瘤头蚜应采用综合措施，控制桃瘤头蚜于卷叶之前。
This work was carried out during 1993-1995. The results show that in the annual cycle Tuberocephallus momonis has 12-14 generations. The periods of gundaliix fundatrigenia,pexupara and sexuales equally are 17、12、15、22、27 days respectively. The winged migrants, migranting from summer host to peach tree, are the sexsuaparae which produce the sexuales. The favourable range of temperature for development of the aphid is 15-23℃. Nutritive condition is the key factor to influence population and differentiation of the aphid. Six insecticides were tested and only Omethoate and Cyolane showed very well in controlling the aphid. Chemical control should be done before the aphid rolling up the peach leaves. The integrated control of the aphid is also discussed in the paper.
