Biological insecticides are substances derived from natural sources that are used to control insect pests. They are considered to be an eco-friendly alternative to synthetic insecticides, which can be harmful to the environment and non-target organisms. Tiger beetle is one such natural source that is used as a biological insecticide.

Tiger beetle as a biological insecticide:

- Tiger beetles are predatory insects that feed on other insects, such as ants, grasshoppers, and beetles.
- They are known for their speed and agility and are able to catch their prey in mid-air.
- Some species of tiger beetles have been found to be effective in controlling agricultural pests, such as aphids and caterpillars.
- The larvae of some species of tiger beetles are also known to feed on the eggs and larvae of other insect pests.
- Tiger beetles are considered to be a safe and effective alternative to synthetic insecticides, as they do not harm non-target organisms and are biodegradable.

Benefits of using biological insecticides:

- They are eco-friendly and do not harm the environment.
- They do not leave harmful residues on crops.
- They are specific to the target pest and do not harm beneficial insects.
- They do not lead to the development of insect resistance, as they work through multiple modes of action.
- They are safe for humans and animals.

Conclusion:

Tiger beetles are one of the many natural sources that can be used as a biological insecticide. They are effective in controlling insect pests and are considered to be safe and eco-friendly. The use of biological insecticides is a sustainable approach to pest control and can help reduce the dependence on synthetic insecticides.

Tiger beetles are biological control agents in agro ecosystem which live on the soil where they capture and consume a wide assortment of soil dwelling insects ,including caterpillars, wire worms, maggots, ants ,aphids and slugs and thus used as a biological insecticide
