Sitophilus granarius is a serious stored-grain insect that can destroy the whole grain of cereal crops. The present research demonstrated that two species of entomopathogenic fungi (EPF), Beauveria bassiana and Metarhizium anisoplidae, killed the treated adults of S. granarius when applied via oral ingestion. Mortality of S. granarius was shown by growth and development of the ingested conidia in the insect gut causing death of infected insects. During bioassays, the fungus conidia were mixed with wheat flour then provided to the insects for feeding on the mixture for 24 h. The insects were surface-treated with a contact fungicide (Merpan®) to kill the external conidia that could penetrate the cuticle and develop to kill the infected insects. Results indicated that the most effective ratio of mixing fungus conidia with the wheat flour was 0.1:2.0 (g/g) where this ratio should contain 2.75 × 10 8 conidia/g of M. anisopliae mixture or 2.6 × 10 8 conidia/g of B. bassiana mixture. Ingested conidia of each fungus caused a first mortality of S. granarius adults after 10 and 12 days of B. bassiana and M. anisopliae treatments, respectively. They also caused 50% mortality after 2.787 and 3.047 weeks of treatments for the same fungi, respectively. The novelty of this research is in adjusting and applying a technique of disinfection of insect cuticle with a fungicide and then verifying the presence of applied fungi in the infected insects. The practical application of this method was discussed.

“…The genus Lecanicillium is known for its entomopathogenic properties and infects a wide range of insects [ 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 ]. Strains of Lecanicillium ( Verticillium ) lecanii Zimmermann are not only commercially available to control severe agricultural pests [ 36 ], but have also been shown to be effective against storage pests such as S. oryzae [ 37 ], S. zeamais [ 38 ], and the red flour beetle Tribolium castaneum Herbst (Coleoptera: Tenebrionidae) [ 39 ]. Extracts containing secondary metabolites from L. attenuatum exhibited the highest insecticidal activity against the Asian tiger mosquito Aedes albopictus (Skuse) (Diptera: Culicidae) and the diamondback moth Plutella xylostella (Lepidoptera: Plutellidae) [ 40 ].…”

There is ample evidence that entomopathogenic fungi can be used as alternative biological control agents for the management of insect pests in storage facilities. As the market demands more environmentally friendly methods and chemical insecticides become increasingly obsolete, more studies are being conducted to evaluate new strains of entomopathogenic fungi for their efficacy in storage facilities. In this context, we tested ten species of fungi isolated from soil, belonging to the genera Cladosporium, Condenascus, Lecanicillium, and Penicillium, for their long-term effects on economically important beetle species. Whole wheat was directly sprayed with a conidial suspension of 108 spores/Ml of each of the tested fungi and then adults of Sitophilus granarius, S. oryzae, S. zeamais, Rhyzopertha dominica, and Trogoderma granarium were placed on the sprayed medium to study the mortality effects. Significantly higher mortality than the control was observed in all treatments. The lowest LT50 (9.164 days) was observed in T. granarium infected with Penicillium goetzii. The isolate with the strongest results was L. dimorphum, which recorded remarkably low LT50 values in S. oryzae (~11 days), R. dominica (~12 days), T. granarium (~10 days), and S. granarius (~13 days). However, for S. zeamais, it was more than 16 days. Our results confirm the existing literature on the efficacy of EPF on storage beetles, suggest the possible virulence of wild untested strains, and also highlight the importance of EPF specificity.
