摘要
在室内用绿僵菌液喷洒3种金龟子幼虫,黄闪丽金龟、棕色鳃金龟和直蜉金龟子的感病率分别为90.2%、50.0%和83.3%。用黄闪丽金龟子幼虫作试验,在室内观察不同施用菌剂的方法对该虫的防效,结果土壤中施用菌剂,在菌土比为1:1250时,防效为86.2%;用菌剂拌麦种(菌剂麦种比为1:10)防效为62.5%;在小麦出苗后分3次施用菌液,防治效果为64.8%。
aboratory atomization of three speies of Chafer grubs by
Metarhizium-anisopliae spore suspension showed: The morbidity of Mimela testaco
viridis,Holotrichiaparallela and Aphodius rectus were respectively 90.2%, 50.0% and
83.3%.Different ways of applying the fungus showed aifferent conthel effect rate (CER) to
Mimela testaco viridis.When fungus spore to aoil ratio 1:1250,CRE was 86.2%; when fungus
sporeswas mixed up with wheat(seed at a rate of 1:10),CER was 62.5%; when the spore
suspension were sprayed three times at wheat seedling stage, CER was 64.8%.
