Hey kiddo, have you ever heard of insects? Well, sometimes there are insects that can cause a lot of damage to crops and plants. That's where biological insecticides come in.
Biological insecticides are like medicine for plants that are sick with insect problems. Instead of using chemicals like traditional insecticides, they use tiny organisms, like bacteria or fungi, that can help to get rid of the bugs that are harming the plants.
These tiny organisms act in a special way to help control the pests. For example, some bacteria produce toxins that are harmful to insects, while others can infect them and cause them to stop eating, which weakens them and makes them easier to control.
The great thing about these biological insecticides is that they are usually safe for people and the environment. They break down quickly and are often specific to the pests that they control, meaning that they won't harm other helpful insects like bees or ladybugs.
So, in summary, biological insecticides are a special kind of medicine for plants that use tiny organisms to control pests in a safe and effective way.
