摘要
应用 9个绿僵菌品系对鞭角华扁叶蜂幼虫致病性测定 ,初选出的 2 0 60和 2 0 55菌株的致病率分别达 76.5%和 2 3 .5%。通过 7代毒力增效试验 ,两品系毒力分别增加了2 3 .5%和 2 8.5%。并用 2 0 60品系菌株在林间防治试验和人工模拟试验 ,其防治效果分别达61 .5%和 65.2 %。经与化学农药复配防治效果可达 96.2 %。
This paper reports the results of the tests in control of the Metarhizium anisopliae to Chinolyda flagelli Cornis.The results showed that Strain 2 0 60 and Strain2 0 55had the highest pathogenicity among the nine strains of M.anisopliae in laboratory and field.The corrected mortality of the larvae was from1 0 0 .0 %and52 .0 %.When the larvae of C.flagellicorniswas controlled by spray the powder in forests,the mortality of the larvae was61 .5%.The larvae of C.flagellicornis was controlled by spray powder of the mixed of the2 0 60 Strain spores with the alphamethrin in forest.The mortality of the larvae was96.2 %after72 hours.
