不同菌株绿僵菌对粒肩天牛幼虫的致病力及林间防治效果
Control efficiency and pathogenicity in different strains of Metarhizium anisopliae on Apriona germari Hope larvae
摘要
Abstract
Apriona germari Hope is a main insect pest of poplar in Fujian province. In order to screen high virulence strains from Metarhizium anisopliae against A. germari larvae, bioassays from seven strains of M. anisopliae were carried out through dipping in spore suspension. The results showed that the cumulative corrected mortality of A. germari larvae inoculated with Mal291 -2 and Mal775 strains reached to 89. 47% and 88. 92% after 14 d treatment. While LT50v alue of the two strains were 5. 62 d and 5. 82 d, and LC50 value were 1. 70 × 10~4spore/mL and 6. 16 × 10~4spore/mL, respectively. It could be concluded that Mal291 -2 and Mal775 had higher virulence than the other strains,with rapid growth and high sporulation. A separate field bioassay suggested that Mal291 - 2 and Mal775 could be used to control A. germari larvae, with 1. 5 × 10~8 spore/mL.关键词
