Establishment of Waterhyacinth Weevil Populations in Louisiana
Manning JH. 1979. Establishment of Waterhyacinth Weevil Populations in Louisiana. Journal of Aquatic Plant Management. 17:39-41
Two species of waterhyacinth weevils were introduced into Louisiana in 1974. Several field nursery areas were established for use as collection sites for distribution of waterhyacinth weevils on a statewide basis. During a four year period, 158,026 Neochetina eichhorniae Warner were realeased at 492 locations and 5,652 Neochetina bruchi Hustache at 10 locations. Waterhyacinth weevil populations in South Louisiana are expanding and appear to be stressing waterhyacinth populations in several locations.
