Useful tips to check red palm weevil in coconut
Red palm weevil is the most destructive pest of coconut. The adult weevil is reddish brown in colour with a life span of 70-130 days. The female weevil lays its eggs in soft tissues of young palms and in the wounds present on the stem or leaf stalk. The larval period ranges from 36-78 days. Stem infestation The wounds in the stem region attract the weevil for egg laying. The grubs on hatching enter through the wounds and damage the trunk by tunnelling inside. Brownish black viscous fluid oozes out from the damage spot on the trunk.
