Pest Control Technician Practice Exam Prep, Study Guide & Practice Test

Fungal pathogens primarily affect insect pests by infecting and ultimately killing them. These pathogens enter the insect's body, often through the cuticle or natural openings, and begin to grow and reproduce inside the host. As the fungus proliferates, it consumes the tissues of the insect, leading to ultimately lethal outcomes. Some well-known examples of such fungal pathogens include the genera Beauveria and Metarhizium, which have been studied for their effectiveness in biological pest control.

The interaction between fungi and insects can significantly impact pest populations, as it reduces their ability to feed and reproduce, thus managing infestations in a natural and environmentally friendly way. Understanding this relationship is crucial for pest control technicians, as they can utilize fungal pathogens as a biocontrol measure against certain insect pests.
