IntroductionThe lesser mealworm Alphitobius diaperinus (Panzer) (Coleoptera: Tenebrionidae) is a ubiquitous and significant insect pest in commercial poultry house litter. The young chicks ingest larval and adult of the lesser mealworms, which negatively affects their performance and behavior, and causes gastrointestinal lesions (Despins & Axtel, 1995; Japp, 2008). The insect plays a potential...

Can the alternative use of biological control restore the activity of chemical molecules?

The fungus has direct impact in the lesser mealworm population reduction. It acts on both resistant and non-insecticide resistant insects. So, it is an alternative to restore the activity of chemical molecules.

We believe it is a great tool for the management of insecticide resistance in the population of the lesser mealworm.

It was reported by the authors that the use of B. bassiana poses no risk to birds or humans. Today there is a big concern and global discussion regarding the harmful action of insecticides on pollinating bees. What is the risk of using Bb for other insects on nature, including bees?

I have been working with entomopathogenic fungi since 1988. I have never see negative results with this microrganisms. According to Zimmermann (2007): “Based on the present knowledge it is concluded that Beauveria species are considered to be safe.”

ZIMMERMANN, G.. Review on safety of the entomopathogenic fungi Beauveria bassiana and Beauveria brongniartii. Biocontrol Science and Technology, 2007; 17(5/6): 553-596

In addition, the risk inherent in the entomopathogenic fungus use is considerably lower than that from the use of chemical insecticides.
