Plutella xylostella


Host crop

Description

This small moth is colored gray and brown. It can potentially identified by a cream-colored band that may be present in the shape of a diamond on its back. The diamondback moth has a wingspan of about 15 mm and a body length of 6 mm. The forewings are narrow, brownish gray and lighter along the anterior margin, with fine, dark speckles. A creamy-colored stripe with a wavy edge on the posterior margin is sometimes constricted to form one or more light-colored diamond shapes, which is the basis for the common name of this moth. The hind wings are narrow, pointed toward the apex, and light gray, with a wide fringe. The tips of the wings can be seen to turn upward slightly when viewed from the side.

Life cycle

Diamondback moth has four life stages: egg, larva, pupa and adult. Crop damage is caused by the larval stage. Normally, the diamondback moth takes about 32 days to develop from egg to adult. The adult moth is approximately 8 to 9 mm (1/3 inch) long with a wing span of 12 to 15 mm (½ inch). Adult females lay an average of 160 eggs during their life span of about 16 days. Eggs are oval, yellowish white and tiny. They are glued to the upper and lower leaf surfaces singly or in groups of two or three. Eggs hatch in about five or six days. Immediately after hatching from the egg, larvae burrow into the leaf and begin mining the leaf tissue internally. After feeding within the leaf for about a week, the larvae exit from the underside of the leaf and begin feeding externally. during the larval stage which lasts about ten to 21 days, depending upon temperature and the availability of food. At maturity the larvae are about 12 mm (½ inch) long. the pupae are light green but as they mature, they become brown as the adult moth becomes visible through the cocoon. The pupal stage lasts from five to 15 days, depending on environmental conditions.

Pest Identification

The adult is a small, slender, grayish-brown moth with pronounced antennae. It is about 6 mm long, and marked with a broad cream or light brown band along the back. The band is sometimes constricted to form one or more light-colored diamonds on the back, which is the basis for the common name of this insect. When viewed from the side, the tips of the wings can be seen to turn upward slightly. Adult males and females live about 12 and 16 days, respectively, and females deposit eggs for about 10 days. The moths are weak fliers, usually flying within 2 m of the ground, and not flying long distances. However, they are readily carried by the wind.

Plant damage is caused by larval feeding. Although the larvae are very small, they can be quite numerous, resulting in complete removal of foliar tissue except for the leaf veins. This is particularly damaging to seedlings, and may disrupt head formation in cabbage and cauliflower.

Insect Sex Pheromone Technology: It is the process of attraction, and trapping the insect those damages to crops.
