禾谷缢管蚜(Rhopalosiphum padi L.)是我国许多小麦种植区的重要小麦害虫,严重影响小麦的正常生长,引起减产和品质下降;禾谷缢管蚜还会传播麦类黄萎病,使病株枯黄矮化,穗小粒少,常导致减产40％以上。作者根据防治工作的需要,对云南小麦禾谷缢管蚜部分生物学及特性以及不同小麦品种对禾谷缢管蚜生物学特性影响进行了研究,现将结果报导如下。 Rhopalosiphum padi L. is one of the most important wheat pests in many wheat growing areas in China, which seriously affects the normal growth of wheat and leads to the decrease of yield and quality. The cereal aphid also transmits wheat wilt, Withered yellow dwarf disease, spikelets less often lead to more than 40% reduction. Based on the need of prevention and control work, the author studied the biology and characteristics of some wheat aphids and the effects of different wheat varieties on the biological characteristics of Aphis gossypii in Yunnan wheat. The results are reported as follows.
