Susceptibility of apple clearwing moth larvae, Synanthedon myopaeformis (Lepidoptera: Sesiidae) to Beauveria bassiana and Metarhizium brunneum
Biocontrol Science and Technology 20 (7), 703-707
Abstract: Apple clearwing moth larvae, Synanthedon myopaeformis (Lepidoptera: Sesiidae) were found to be susceptible to infection by two entomopathogenic fungi: an indigenous fungus isolated from S. myopaeformis cadavers and identified as Metarhizium brunneum (Petch); and Beauveria bassiana isolate GHA. In laboratory bioassays, larvae exhibited dose related mortality after exposure to both the M. brunneum and Beauveria bassiana with 7 day LC50's of 2.9 x 105 and 3.4 x 105 spores/mL, respectively. Larval mortalities caused by the two isolates at 1 x 106 spores/mL were not significantly different and 73% of the M. brunneum-treated, and 76% of the B. bassiana-treated larvae were dead 7 days post treatment, with LT50's of 5.5 and 5.1 days, respectively.
