Presence of insects in the field may or may not be an indication of a problem.  In any case, it would be important to recognise the insect and mite pests that harm the crop, on one hand, and those that are beneficial to the crop, on the other. As we hope to reduce the population of the pests to a level that will not result to significant damage to the crop, we also wish to preserve or increase the population of the beneficials to help us prevent or control the damage caused by the pests.  

If you have seen any of these insects in the field  please click on the underlined name to get to each fact sheet and learn more about them. If you want to  get a bigger and better view of the image just click on the image itself.
