(Lepidoptera: Geometridae) under laboratory conditions. Reared larvae were sprayed with the fungal suspension at a concentration of 1 × 10~8 conidia mL~(-1). All three fungi species tested increased mortality of larvae as compared to control (distilled water spray). The highest (100%) mortality was caused by B. bassiana within 12 days, followed by M. anisopliae: 18 days were needed to reach the same mortality level. The lowest mortality was caused by I.farinosa: even double spray resulted only in 56.67 ± 6.6% mortality. The most effective entomopathogene was B. bassiana. 收起
