Can Fungus Control Insects

Understanding Entomopathogenic Fungi 

Fungus, a type of microorganism, plays a crucial role in our ecosystem. While most people associate fungi with mushrooms and molds, they also have the remarkable ability to control insects. This natural phenomenon is known as entomopathogenic fungi, which refers to fungi that can infect and kill insects.

The Intricate Relationship Between Fungi and Insects

Entomopathogenic fungi have evolved to specifically target insects, making them an effective and environmentally friendly alternative to chemical insecticides. These fungi belong to different families, including Beauveria, Metarhizium, and Cordyceps, each with its own unique characteristics and target insects.


The Invasion and Takeover

When a fungus comes into contact with an insect, it attaches to the insect’s cuticle (outer covering) and starts to invade its body. The fungus then grows inside the insect, eventually causing its death. This process is facilitated by the secretion of enzymes that break down the insect’s tissues, allowing the fungus to absorb nutrients and reproduce.


Beauveria bassiana: A Versatile Insect Assassin

One of the most well-known examples of entomopathogenic fungi is the species Beauveria bassiana. This fungus has a broad host range and can infect various insects, including aphids, whiteflies, beetles, and caterpillars. Beauveria bassiana can be applied as a biopesticide, either in the form of a spray or as a dust, to control insect populations in agricultural and horticultural settings.


Metarhizium anisopliae: Subduing Soil-Dwelling Pests

Metarhizium anisopliae is another commonly used entomopathogenic fungus. It primarily targets soil-dwelling insects, such as termites and certain species of beetles. Due to its effectiveness and specificity, Metarhizium anisopliae has been extensively studied for its potential use in integrated pest management strategies.


Cordyceps: The Mind-Controlling Fungus

Cordyceps, a genus of fungi, is known for its peculiar and fascinating behavior. Certain species of Cordyceps have developed the ability to manipulate the behavior of their insect hosts. For example, Cordyceps unilateralis infects ants and compels them to climb to high locations before killing them. The fungus then sprouts from the ant’s body and releases spores to infect other ants.


Indirect Benefits for Pest Control

In addition to their direct effects on insects, entomopathogenic fungi can also have indirect benefits for pest control. These fungi can reduce the reproductive capacity of insects, disrupt their feeding behavior, and impair their ability to transmit diseases. Furthermore, entomopathogenic fungi are generally safe for humans, other animals, and the environment, making them a desirable alternative to chemical pesticides.


Factors Affecting Effectiveness

However, it is important to note that the effectiveness of entomopathogenic fungi can vary depending on various factors, including environmental conditions, insect species, and the specific strain of fungus used. Additionally, their mode of action may take longer to achieve control compared to traditional chemical insecticides. Therefore, proper monitoring and application techniques are essential for successful implementation.


Promising Alternative for Sustainable Pest Control

In conclusion, entomopathogenic fungi have demonstrated their ability to control insects effectively. These fungi offer a natural and environmentally friendly approach to pest management, with the potential to reduce reliance on chemical pesticides. As research and understanding of these fungi continue to grow, they hold great promise for sustainable pest control strategies in various fields, from agriculture to public health. So, to answer the question “Can fungus control insects?” – Yes, it can, and it offers a promising alternative for insect control.

We thought we had bedbugs but could find no evidence apart from what we thought were bites. I called Bon Accord and Gabriel was there within a couple of hours. He told us we had carpet beetle. Finding the evidence and showing us photos of the skin reaction which was exactly what we had. He advised and returned at a time to suit us to spray which was done thoroughly and efficiently. No sign of the little critters returning. Thank you Gabriel.

Top-notched pest control service!! Went above and beyond to eradicate the rats from our property. Gabriel even offered to further investigate the infestation issues for our neighbours. We found him to be extremely professional and easy to work with. We highly recommend Gabriel to anyone in need of pest control.

Gabriel was absolutely wonderful, a real life saver when I found a mouse by my bed at 10pm. He came in less than an hour and was able to catch the mouse and put my mind at rest so I could go to sleep! Highly recommend, fab service and lovely people.

Gabriel turned up with an hours notice one evening and immediately identified the issued. He works efficiently and professionally throughout with timely follow-ups to ensure the problem was resolved. Once completed he was kind enough to continue to check in to see that the issue had gone. Having had Rentokil previously that spent two years doing very little this was a complete breathe of fresh air and solved the problem in less than two weeks. We are grateful and would highly recommend his services.

We were lucky to have found Bon Accord, they responded very fast to our request and Gabriel was very helpful and informative. He made several visits and did his absolute best until the mice problem we had was gone. Highly recommended.
