The neem extract does not have the same effect on all insect species. Some pest groups can be easily controlled. The feeding behaviour of other groups may be influenced or their ability to reproduce impaired, but this does not prevent direct damage to the plants. Some insects react minimally or not at all to the extracts.

Given below you will find more detailed information on the reactions of pests of neem extracts. It is important to note, however, that this is not intended as a precise description of the effects of neem extracts but as a guide which gives the user advice as to which pests may be controlled by application of neem.
