“…Their contact mode of action and ability to secrete insecticidal compounds put them at the vanguard of the global development of alternative control strategies . Among them, it is worth mentioning the genus Metarhizium , which comprehends several species of a great efficacy as biocontrol agents, such as Metarhizium anisopliae (Metsch) (Hypocreales: Clavicipitaceae) and Metarhizium brunneum Petch (Hypocreales: Clavicipitaceae) . As generalist entomopathogenic fungi, Metarhizium spp.…”

BACKGROUND The cotton leafworm, Spodoptera littoralis, is one of the most destructive pests in the Mediterranean basin, being predominantly controlled using synthetic chemical pesticides. Strain EAMa 01/58‐Su of the fungus Metarhizium brunneum and the parasitoid Hyposoter didymator are promising biological control agents for this pest. In this study, we assessed the compatibility between these two agents to control S. littoralis under joint attack scenarios. RESULTS Firstly, the direct and indirect effects of the fungus towards parasitoid adults were studied. The fungus significantly decreased life expectancy of the parasitoid (mortality = 62.5%; mean lethal concentration = 1.85 × 106 conidia ml−1; average survival time = 92.2 h) when applied at high concentrations (108 conidia ml−1), whereas it did not affect the reproductive potential of the parasitoid females during the 3 days after treatment. Secondly, the combinations between the two agents to control S. littoralis under different simultaneous use scenarios (inoculation of S. littoralis larvae with the fungus before being exposed to parasitoid females and vice versa) were investigated, with additive effect in all cases. A significant effect on fitness (preimaginal development time and reproductive potential) of the F1 parasitoid generation were detected. Moreover, parasitization significantly reduced the total hemocytes in S. littoralis hemolymph compared with the control, promoting fungal infection. Finally, parasitoids showed a significant preference for non‐inoculated S. littoralis larvae. CONCLUSIONS We demonstrated compatibility (additive effect) between fungus and parasitoid under different joint attack scenarios to control S. littoralis in laboratory conditions. However, this will be supported by our ongoing greenhouse and field studies. © 2019 Society of Chemical Industry

“…Occurrence of these two species in the agroecosystem could be attributed to the specific geographic distribution of the fungus. Species of M. anisopliae vary across different regions (Brunner‐Mendoza et al ), and predominance of M. pingshaense in rhizosphere of wild plants was observed in Japan (Nishi and Sato ). In the present study, M. anisopliae isolates were partitioned into three phylogenetic species, further reinforced by allelic differences in maximum‐likelihood analysis of multiple microsatellite loci.…”

Aims To assess phylogenetic and genotypic diversity of Metarhizium anisopliae lineage within diverse agroecosystems in the Karnataka State of India and to compare their chitinase activity and pathogenicity against insect pest of field crops subterranean termite, Odontotermes obesus. Methods and Results Three phylogenetic and 27 microsatellite markers were used to assess the genetic diversity of M. anisopliae lineage within multiple agroecosystems. Multilocus phylogeny of the Metarhizium isolates identified two species: Metarhizium pingshaense and Metarhizium guizhouense. Multilocus phylogeny and microsatellite markers resolved two phylogenetic species of M. pingshaense, Mp_1 and Mp_2, and one phylogenetic species of M. guizhouense, Mg_1. Phylogenetic species, Mp_2 and Mg_1, were detected with one genotype each and Mp_1 with eleven genotypes. Metarhizium pingshaense GKVK 02_16 isolate caused significantly high mortality of O. obesus in bioassays and detected with high chitinase activity. Conclusions The study revealed phylogenetic and genotypic diversity of M. anisopliae lineage in agroecosystems of Karnataka State. Findings of pathogenicity and chitinase activity suggest that M. pingshaense GKVK 02_16 isolate provides effective control of O. obesus. Significance and Impact of the Study The investigation provided an understanding of the genetic diversity and biocontrol efficiency of M. anisopliae lineage in agroecosystem. These data will serve as a resource in the future pest management strategies at a regional scale.

“…The sterilized dead adults were then kept individually in Petri dishes on a damp filter paper until mycelia appeared. Sitophilus cadavers showing external mycelia growth were examined using a microscope ZEISS Primo Star (Carl Zeiss Microscopy GmbH, Jena, Germany) at a 400x magnification, and fungi were determined based on the shape and size of hyphal growth [36][37][38][39].…”

The insecticidal virulence of various entomopathogenic fungal isolates retrieved from soil samples was tested on adults of the granary weevil Sitophilus granarius (L.) (Coleoptera: Curculionidae). Bioassays were carried out in the laboratory where experimental adults were sprayed with 1 mL of conidial suspension (108 conidia/mL) from each isolate. Mortality was recorded at 7, 14, and 21 days after exposure. Mean mortality, mean lethal time, survival, and hazard effect were estimated for each isolate. Two isolates of Beauveria bassiana (Balsamo) Vuillemin (Hypocreales: Cordycipitaceae), one isolate of Aspergillus insuetus (Bainier) Thom & Church (Eurotiales: Trichocomaceae) and Metarhizium anisopliae (Metschinkoff) Sorokin (Hypocreales: Clavicipitaceae) resulted in the highest mortality (97–100%). The isolates with both the highest hazard effect and the lowest survival rate were Aspergillus sp. and M. anisopliae. Our results indicate that entomopathogenic fungi have the potential to become a very useful tool in reducing chemical applications in storage facilities.
