Onion is a most important culinary commodity grown in India. Full yield potential of the crop is not realized due to number of constraints. Among them pest and diseases are the major constraints in onion production. Pest management is crucial for obtaining good quality marketable bulb. Major insect pests of onion with their symptoms are given below:
1 Onion thrips, Thrips tabaci Lindeman (Thysanoptera: Thripidae) : Onion thrips is a key insect pest in most onion and garlic production regions of the world. They are cosmopolitan in nature and can feed on broad host range. Some of the important alternate hosts are cabbage, cauliflower, cotton, melons and many flowering plants. Both Immature and adult thrips feed by piercing surface tissues and suck the exuded plant juices. They cause direct damage to leaves and bulbs and also act as vector for viral diseases.
2 Head Borer, Helicoverpa armigera Hubner (Noctuidae: Lepidoptera) : This is sporadic pest and attack onion grown for seed purpose.
Larvae feed inside the stem and move upwards to reach the base of the umbel at early stages of flowering. Subsequently, it invades the umbel and feeds on seeds. As a result, complete drying of flowers and complete loss of seed occurs. The larva of this insect cuts the pedicel of the flower and feeds on the stalk. Single larva damages many flower stalks. The fully-grown larva is greenish with dark brown grey lines along the side of body and measures about 35-45 mm in length.
3 Cutworms, Spodoptera litura Fabricius (Noctuidae: Lepidoptera) : The larvae of this insect are seen in nursery beds and newly transplanted onion fields. The tender plants are found damped at ground level during the night young larvae feed gregariously on foliage but later segregate and enter into soil. Young larvae are yellowish grey and later on become brown, greasy to touch and coil when disturbed. They cut the seedlings at ground level during night and hide during day.
