“…However, in this study, no differences were found between males and females. These results differ to those reported by Tafoya et al. (2004), where males were found to be more susceptible than females to isolates of B. bassiana .…”

“…The results showed infection was greater when inoculated with isolates of B. bassiana compared with isolates of M. anisopliae . Although B. bassiana has been previously reported as infecting M. spinolae (Tafoya et al. 2004), this is the first report of M. anisopliae infecting this pest.…”

“…2009; Dembilio et al. 2010), there is only one report of virulence against M. spinolae , in which the susceptibility of adults to Beauveria bassiana (Balsamo) (Vuillemin) (Ascomycota: Hypocreales) was assessed (Tafoya et al. 2004).…”

Aims: To evaluate different entomopathogenic fungal isolates against the cactus weevil Metamasius spinolae under laboratory and field conditions, and select an isolate to be used as a tool in the management of this insect pest. Methods and Results: Four experiments were carried out. The effect of temperature on the in vitro growth of eight isolates of entomopathogenic fungi (two Metarhizium anisopliae and six Beauveria bassiana) was assessed. The susceptibility of adult M. spinolae to the same isolates was evaluated. Using three selected isolates, the interaction between susceptibility and sex of the insect was studied. Finally, a field experiment was carried out to evaluate infection of adult M. spinolae by the same three isolates under natural abiotic conditions. Overall, growth rate was greatest at 25°C for all the isolates. In vitro growth of M. anisopliae was greater than B. bassiana. Mortality of adult M. spinolae was greater when inoculated with B. bassiana compared with isolates of M. anisopliae. Susceptibility had no interaction with the sex of the insect. The proportion of insects succumbing to infection was smaller when incubated under field conditions than when incubated under laboratory conditions. Conclusions: The experiments described here showed a complex interaction between entomopathogenic fungi and M. spinolae, and these data allows us to select isolate Bb107 as a first step towards its use in the management of this pest insect. Significance and Impact of the Study: Our results showed that entomopathogenic fungi can be used for the control of M. spinolae, which may help reduce the use of chemical insecticides and, therefore, the exposure of Opuntia ficus‐indica producers to pesticides.

“…It has been reported that mortality (M) and LT 50 in insects infected by B. bassiana depends upon species, nutrition state, and developmental stage of the insect (Cherry et al, 2005;Tafoya et al, 2004), as well as infection techniques and environmental conditions used in bioassays (Posada and Vega, 2005;Safavi et al, 2007). These variables could account for differences in M and LT 50 found in our work.…”

“…The potential of entomopathogenic fungi as biocontrol agents, particularly of B. bassiana and M. anisopliae, has been evaluated against several weevils species as Callosobruchus maculatus (Murad et al, 2006), Conotrachelus nenuphar (Alston et al, 2005), Metamasius spinolae (Tafoya et al, 2004), Rhynchophorus ferrugineus (Dembilio et al, 2010), Sitophilus zeamais (Adane et al, 1996). Furthermore, these fungi are able to cause death in the boll weevil, both in the laboratory (Domingues da Silva, 2001;Giometti et al, 2010;Wright and Chandler, 1991) and in the field (Wright, 1993;Wright and Chandler, 1992).…”
