Negative effects on the development of Chrysodeixis includens and Spodoptera cosmioides fed by peanut plants inoculated with entomopathogenic fungi

Recent studies have shown that entomopathogenic fungi, as endophytes, can beneficial effects on plants, protecting them from defoliating insects. The potential of endophytic association by fungi with the peanut crop has been little explored. In our study, we conducted experiments inoculation seeds through a soil drench method nine strains/species genera Metarhizium , Beauveria and Cordyceps subsequently these plants were consumed two larval pests, Chrysodeixis includens Spodoptera cosmioides . parameters growth rates, mortality, foliar consumption period observed during development larvae. addition, capacity in their persistence investigated. replicate greenhouse trials for each larva, inoculated soil-drench method. We evaluated performance C. S. feeding starting at 2nd instar. pupal weights significantly different among fungal treatment groups, where insects control exhibited higher than treated plants. differences showed Control larvae pupated faster fed fungal-inoculated treatments had 3 to 5 days more control. mortality rates survival all was compared other only B. bassiana IBCB215 emerged phyllosphere Although fungus presented worst treatments. Overall, results demonstrate negative best recorded strains IBCB215.
