Effect of some phytopathogenic fungi and their metabolites on growth of Heliothis virescens (F.) and its host plants



Effect of some phytopathogenic fungi and their metabolites on growth of Heliothis virescens (F.) and its host plants



Biocontrol Science and Technology 4(1): 77-87



Eleven fungal isolates and their secondary metabolites incorporated into artificial diet were tested for oral toxicity to Heliothis virescens by examining larval weight, efficiency of conversion of ingested food to body tissue (ECI), pupal weight, days to pupation, and mortality. Two isolates of Alternaria alternata, 2 isolates of Fusarium moniliforme, 3 isolates of F. oxysporum and an isolate of F. solani reduced larval weight by 90-99% after 7 days and inhibited pupation.
