Nicotiana insecticida is a wild tobacco plant that traps and kills insects. It is a newly discovered species found in a Western Australian highway. The sticky hair on the plant?s surface enables it to trap insects like flies, gnats and aphids. Despite its predatory features, it is not an insectivorous plant as it does not dissolve the insects and soak their nutrients. Rather, the sticky hair prevents the plants from being the prey of the trapped insects.
The defensive feature of Nicotiana insecticida can enable it to act as natural insecticide, as it can protect other plants growing close by. It can minimise the use of chemical-based pesticide and insecticide, which harms the environment and health.
