HOW DOES NEEM WORK, WHAT IS THE MODE OF ACTION AND HOW DOES IT AFFECT INSECTS?
Numerous insect species are repelled by active ingredients in the neem seed. As they find the taste and smell unpleasant they avoid the plants that have been treated with neem extracts. Other insects die some time after having eaten leaves or other parts of the plant treated with these substances. They alter the behaviour in some insects or reduce their ability to lay eggs. Other pest species are affected minimally or not at all by the neem substances, probably as a result of their hidden biology.
