DD—136是我国于1979年从国外引进的一种虫生带菌新线虫(Neoaplectanacarpocapsae)的优良品系。我所自1980年以来利用它进行了防治粘虫的试验研究,并取得一些初步结果,现初报如下。 一、培养技术的改进 对设计的19种DD—136线虫培养繁殖方案进行初步筛选,结果以越冬红铃虫幼虫体加麦麸培养繁殖方法较好,具体做法是:以3:3:1的比例,将虫体、麦麸、谷壳混合,加水拌匀呈半干半湿,装瓶。装入量
DD-136 is an excellent strain of neoaplectanacarpocapsae introduced from abroad in 1979 in our country. I have been using it since 1980 to test and control mythimna separata, and achieved some preliminary results, the first report is as follows. First, the improvement of training technology The design of 19 DD-136 nematode breeding program preliminary screening, the results of the overwintering Red Bellisia larvae plus wheat bran culture and propagation method is better, the specific approach is to: 3: 3: 1 Proportion, the parasites, wheat bran, chaff mixed, add water and mix was semi-dry, bottling.
