Susceptibility of Artipus floridanus to Different Isolates of Beauveria bassiana

Literature on the entomopathogens of adult and larval root weevils is reviewed. A quantitative study to determine the pathogenicity and sporulation on larvae of 34 isolates of Beauveria bassiana to neonatal larvae of Artipus floridanus is reported. Six isolates were determined as potentially superior for microbial control of citrus root weevils. Difference in pathogenicity between fungal types was more pronounced at the lower conidial concentration. Sporulation per cadaver increased with an increase in virulence. No consistent differences in pathogenicity to neonatal larvae of A. floridanus could be detected between exotic and indigenous isolates, insect host, or location.
