Black thrips(THRIPS PARVISPINUS) have become a major insect pest in recent days for chili and capsicum crops. These thrips are also called western trips/flower thrips. These can spread to tomato, brinjal, potato, and other vegetable crops.

The black thrips were only found on the crops like some citrus species plants and most of the time they were more serious on flower crops viz. Gerbera, rose and others.

Symptoms Of Black Thrips Attack:
