Development of aphids Hyadaphis coriandri (Das), its natural enemies and pollinators on coriander (Coriandrum sativum L.)

Abstract

Coriander (Coriandrum sativum L.) is an important seed spice crops belong to family Apiaceae. Rajasthan state cover maximum area and production of coriander in India. An experiment was conducted at NRC on Seed Spices on variety Ajmer Coriander-1 to study development of aphids, predators/parasitoides and pollinators complex at field level over the period of two year. Development of aphids, Hyadaphis coriandri (Das) population were recorded on crop form second week of December to March. Maximum population build up of aphids noticed during March month with highest average population (169.2 aphids umbel-1) of both year was observed in 11th standard week.Among natural enemies complex predator Coccinella and aphid parasitoides Aphidius spp. was most prominent. There were five species of Coccinella found predating on aphids. Other predators were shryphid fly and chrysoperla carnea but their population was noticed at very low numbers. Aphidius species was important aphids parasitoides recorded on the crop. Honey bee species, Aphis florea constitute major pollinator of coriander crops.
