Responses of diamondback moth to diverse entomopathogenic fungi collected from non-agricultural habitats – Effects of dose, temperature and starvation
2022, Fungal BiologyCitation Excerpt :Of particular significance in our results is that inoculation temperature (and we used an exposure of 24 h) had more significant effects on their virulence (average LT50 = 5.2, 4.9, 3.7 and 3.1) than did the temperature to which larvae were subsequently exposed, when the fungi grew in the DBM haemocoel (average LT50 = 6.3, 5.3, 4.3, and 4.0 at 15, 20, 25 and 30 °C respectively) after all had been inoculated and held at 20 °C for 24 h. It is well established that this transition stage in the life cycle is sensitive to humidity (e.g. Doberski, 1981; Fargues et al., 1997) but the influence of inoculation temperature can also be critical. The microclimate within cuticular folds of insects has been suggested by many authors to provide sufficient humidity to ensure in vivo germination, infection and conidiogenesis of EPFs (Doberski, 1981; Fargues et al., 1997b; Wraight et al., 2000; Acheampong et al., 2020).

2020, Journal of Invertebrate PathologyCitation Excerpt :Therefore, a mycoinsecticide product from these isolates, particularly the fastest growers, G 11 3 L6 and FCM Ar 23 B3, is anticipated to be active within the optimal temperature ranges for survival of these pests. The microclimate within cuticular folds of insects has been suggested by many authors as sufficient to ensure in vitro germination and infection by fungal entomopathogens (Doberski, 1981; Fargues et al., 1997b; Inglis et al., 2001; Wraight et al., 2000). Likewise, RH in the boundary layer near the leaf surface, has been experimentally shown to be higher than ambient humidity, which facilitates insect infection by fungal entomopathogens (Boulard et al., 2002; Shipp et al., 2003; Vidal, et al., 2003; Wraight et al., 2000).
Effect of certain entomopathogenic fungi on oxidative stress and mortality of Periplaneta americana
2016, Pesticide Biochemistry and PhysiologyCitation Excerpt :The growth rate of these entomopathogenic fungi is within the optimal range (25–30 °C) but it appears that they are adapted to higher than average temperatures. Different fungal spores in our experiment are able to infect and kill insect hosts at low temperature (10 °C), but the percentage of virulence was low. [57]. Doberski (1981) also reported that isolates of B. bassiana and Isaria farinosa infect larvae of elm bark beetles Scolytusscolytus incubated at 2 and 6 °C.
Effect of Norwegian entomopathogenic fungal isolates against Otiorhynchus sulcatus larvae at low temperatures and persistence in strawberry rhizospheres
2015, Biological ControlCitation Excerpt :Few fungal isolates are able to infect and kill insect hosts at low temperatures. Doberski (1981) found isolates of B. bassiana and Isaria farinosa (syn. Paecilomyces farinosus) to infect larvae of elm bark beetles Scolytus scolytus at 2 and 6 °C while isolates of Metarhizium anisopliae sensu lato were ineffective at these temperatures.
