2011 m. Nr. 1 Pine defoliator Bupalus piniaria (L.) (Lepidoptera:
Geometridae) and its entomopathogenic fungi.
2. Pathogenicity of Beauveria bassiana, Metarhizium anisopliae and Isaria farinosa
Fungi Beauveria bassiana, Metarhizium anisopliae and Isaria farinosa (local strains), were tested on 3rd and 4th instar larvae of pine defoliator Bordered White moth (Pine Looper), Bupalus piniaria (L.) (Lepidoptera: Geometridae) under laboratory conditions. Reared larvae were sprayed with the fungal suspension at a concentration of 1 × 108 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.
