烟蓟马Thrips tabaci Lindeman在我国各棉区均有分布,尤以黄河流域和内陆棉区危害较重。五十年代往往猖獗,造成棉花缺苗和大量“破头”、烂叶,导致晚熟减产。人民公社化以来,由于垦除了杂草丛生的大量地畔,消除了虫源并推广了3911处理棉种技术,棉苗早期受害才相应减轻。只是在5-7真叶期仍有较重的发生,还应密切注意。现将陕西、山西省的有关资料整理成文,提供防治上参考。
Thrips tabaci Lindeman is distributed in every cotton area in China, especially in the Yellow River and inland cotton areas. Fifties are often rampant, resulting in a large number of cotton seedlings and “broken head”, rotten leaves, resulting in late maturing production. Since the people’s communes, due to the removal of a large number of weeds to the ground, eliminating the source of insects and promote the 3911 treatment of cotton seedling, cotton seedlings suffered the corresponding reduction in the early victims. Only in the true leaf stage of 5-7 is still heavier, but should pay close attention. Shaanxi and Shanxi Province now organize the relevant information into a text, provide a reference for prevention and treatment.
