Virulence potential of Metarhizium anisopliae s.l. isolates on Rhipicephalus (Boophilus) microplus larvae
چکیده انگلیسی

The use of entomopathogenic fungi to control arthropods has been reported worldwide for decades. The aim of the present study was to evaluate the virulence of 30 Metarhizium anisopliae s.l. Brazilian isolates from different geographical regions, hosts or substrates on the larvae of Rhipicephalus (Boophilus) microplus ticks under in vitro conditions to the selection of virulent isolates in order to be further used in biological control programs. The current study confirmed the lethal action of M. anisopliae s.l. isolates on R. (B.) microplus larvae with different mortality levels, usually directly proportional to the conidia concentration. No relationship was found between the origin of the isolate and its virulence potential or between the virulence potential and conidia production. Three isolates (CG 37, CG 384 and IBCB 481) caused a high percentage of larval mortality, reaching LC50 at 106 conidia ml−1, thus requiring a lower conidia concentration to cause an approximately 100% larval mortality. The results of this study suggest that these three isolates are the most promising for use in programs aimed at microbial control in the field.
