Abstract: | AbstractIn this study, Metarhizium anisopliae TR 106 and Beauveria bassiana TR 217 was tested against fourth instar larvae of Thaumetopoea pityocampa. The LT50 and LT90 of 1?×?106 concentration of M. anisopliae against T. pityocampa were 3.60 and 4.11 for direct application, while these were 2.87 and 3.60?days, respectively in leaves application. The LT50 and LT90 of the 1?×?108 concentration of the same isolate were 2.50 and 2.95?days for direct application, and 2.98 and 3.74?days for leaves application. The LT50 of insect and leaves application for 1?×?106 of B. bassiana were 3.75 and 3.49?days, respectively. The LT90 of same concentration for insect application was 4.48?days, while LT90 for leaves application was 4.63?days. Similarly, LT50 of insect and leaves application for 1?×?108 of B. bassiana were 3.03 and 3.31?days, while LT90 were 3.68 and 4.29?days, respectively. Approximate 100% mycosis was observed in all treatments. |
