Bioinsecticide products cover insecticidal microorganisms or natural toxins to achieve the insect-control target. By contact and parasitism, the insects will be killed naturally. These microbes usually exist widely in nature, have been considered as low-toxic insecticides.
Bioinsecticide Mode of Action
1. Contact Killing
Some bioinsecticides’ spores germinate and infect the body after they come in contact with the pests. This bacterium will be in the body of the pests throughout its life cycle, kill the pests by nutrient intake, secreting toxins, destroying the body structure.
2. Affect Feeding
Some bioinsecticides can make pests lose their appetite. Pests are malnourished by suppressing their eating habits and eventually killing them.
3. Affect Growth
Many pests have stage changes during growth, manifested in molting and pupae. Some bioinsecticides can interfere with the process of molting to prevent pests from completing their life cycle and prevent their reproduction.
4. Interfere Multiply
Some bioinsecticides can use pheromones to stop or slow down insect reproduction. A pheromone is a compound that confuses pests that are looking for a partner. If males and females cannot find each other, they cannot reproduce the next generation of pests. Pheromones can significantly reduce the number of offspring produced by pests.
