A laboratory experiment was conducted to determine the conidial discharge of Batkoa amrascae Keller & Villacarlos, an entomopathogenic fungus found infecting the cotton leafhopper on okra. Field and laboratoy-infected leafhopper cadavers were tested for the effect of light. The fungus from field-infected cadavers kept in the dark during sporulation produced and average of 26,372 conidia (29 hr. mean time conidial production), whereas those exposed to light had 5,290 conidia (33 hr. mean time conidial production). On the other hand, laboratory-infected cadavers exposed to light attained an average of 4,447 conidia while that of cadavers kept in the dark had 3,373 conidia, both had 28 hr mean time conidial production.

The entomopathogenic fungus Metarhizium anisopliae (Ascomycota Hypocreales) has recently been found capable of producing compact hyphal aggregates (microsclerotia) under specific culture conditions that become pigmented during growth The microsclerotia can be formulated and are stable when dried for storage Upon rehydration hyphae grow from the microsclerotes develop into a fungal pellet and produce large quantities of conidia In this study microsclerotia were produced using New Zealand USA and Mexican strains of M anisopliae and characterised for production requirements stability and conidial production Microsclerotia were produced in shake flasks and fermenter vessels and differences were observed in growth and production according to strain and CN ratio The potential of microsclerotia formulations for biocontrol of redheaded cockchafer (Adoryphorus couloni Coleoptera Scarabaeidae) is currently under evaluation

AbstractThe eucalyptus snout beetle (ESB), Gonipterus platensis, is endemic to Australia but has become a major invasive, destructive pest of Brazilian eucalyptus plantations. Efforts to develop insecticides based on entomopathogenic fungi against ESB are limited by the lack of known virulent strains. We therefore explored the virulence of indigenous Brazilian strains of major entomopathogenic fungi—Beauveria spp. and Metarhizium anisopliae—against ESB adults. We found widely varying virulence and later capacities for conidial production on infected adult cadavers. Two strains stood out, B. bassiana IBCB-240 and M. anisopliae IBCB-364, as especially lethal for ESB adults under laboratory conditions, sporulated abundantly on infected insects, and also outperformed comparable strains used in commercial mycoinsecticides. Notably, B. bassiana IBCB-240 exhibited lower LT50 values at low inoculum levels (≤ 107 conidia mL−1) and smaller LC50 values than M. anisopliae IBCB-364. Taken together, this study emphasizes natural variation in virulence among indigenous Beauveria and Metarhizium strains against ESB adults and identifies fungal strains with superior lethality to existing commercialized strains for managing this eucalyptus pest in Brazil.
