马尾松毛虫Bt高毒力菌株筛选研究

Screening of High-virulent Bt Strains to Masson Pine Caterpillar

摘要:

为了研究开发马尾松毛虫专用Bt新剂型，本试验对7个Bt菌株进行了杀虫效果的水平筛选，并对高效菌株进行了杀虫浓度梯度的测定。

Abstract:

In order to study and develop specially-used new Bt formulation, this test has carried on parallel screening to insecticidal effect from seven Bt strains and carried out measurement on gradient of insecticide concentration for high effective strains.
