1991—1993年在哈尔滨、牡丹江和阿城等地进行了应用斯氏线虫防治8种害虫的研究,其中鳞翅目5种:粘虫、甘蓝夜蛾、银纹夜蛾、向日葵螟、小菜蛾;鞘翅目3种:白星金龟子、马铃薯瓢虫和细胸金针虫。用3个种5个品系线虫测定的结果表明,除金针虫外,斯氏线虫对其它7种害虫均能侵染。室内试验表明,Beijing品系对粘虫、甘蓝夜蛾、向日葵螟和小菜蛾的致病力最强,害虫死亡率范围为79.3％—100.0％。田间试验表明,Beijing品系线虫对马铃薯二十八星瓢虫具有较好的防治效果。而NC32和Beijing品系在室内和田间对细胸金针虫均未表现出致病力。这些结果表明,斯氏线虫在本省具有广阔的应用前景。
1991 to 1993 in Harbin, Mudanjiang and Acheng and other places, the application of Silvicomone against 8 kinds of pests, Lepidoptera 5 species: armyworm, cabbage Langer, Spodoptera, sunflower borer, diamondback moth ; Coleoptera 3 species: white beetle, potato ladybug and fine-pin insects. The results of three species of five strains of nematodes showed that, except for the golden needleworm, the nematodes were able to infect the other seven pests. Laboratory tests showed that Beijing strains were the most virulent to armyworm, cabbage budworm, sunflower borer and diamondback moth. The mortality rate of pests ranged from 79.3% -100.0%. Field experiments showed that Beijing strains of nematodes on the potato twenty-eight Ladybug has a better control effect. However, NC32 and Beijing strains showed no pathogenicity to the fine-needle insects both in the field and in the field. These results show that the nematodes in the province has broad application prospects.
