It is a pheromone insect lure used to attract target insects.
It is a lure extracted by the males.
It attracts both males and females from the surrounding and are trapped
One lure per trap has to be used and 1 trap has to be installed for 10 trees.
Lures have to be changed once in every 6 months.
Technology:
Insect Sex Pheromone Technology: It is the process of attraction, and trapping the insect those damages to crops.
Per Acre Use:Â Bucket trap with RPW Lure minimum 3-4/acre for controlling.
Description:
Host Crop: Coconut palm, Date palm, Oil Palm & Arecanut palm
Adult weevils are reddish brown, about 35 mm long and 10 mm wide and are
Characterized by a long curved rostrum (snout). Dark spots are visible on the upper side
of the middle part of the body. The head and rostrum comprise about one-third of the total length. In the
male, the dorsal apical half of the snout is covered by a patch of short brownish hairs, the snout is bare in the female, more slender, curved and a little longer than the male.
Damage:
Red Palm Weevil is widely considered to be the most damaging insect pest of palms in the world. In young plantations crown, trunk and bole are the natural sites of damage.In older plantations only crowns are infested. Many a time the insect completes several generations inside the crown or trunk feeding on the inner tissues until the trunk or crown becomes hollow and tree gets killed. After the death of the palm adult weevils come out and seek fresh trees to attack. The legless larvae are yellowish, stout and make galleries inside the tree for about 2-4 months. The adult weevils live for 3-4 months. The females are known to be attracted strongly to the fermenting sap oozing out of wounds in the trunk or the leaf bases.
Life Cycle:
The Red Palm Weevil, like other beetles, develops through complete metamorphosis, with larvae and pupae developing within the trunk and apical growth tissues of the palm meristem. Larvae are legless grubs with the body color uniformly pale yellow with a brown head. Larvae may attain lengths greater than 50 mm (2 inches). Larvae feed within the soft tissues of the meristem or leaf bases creating frass filled mines,
enlarging and penetrating deep within the upper trunk areas as the larvae mature.Mature larvae construct a pupal chamber or cocoon made up of coarse palm fibers in which they pupate and occupy for approximately three to four weeks. The cocoons are located within the damaged tissue of the palm.
