Biocontrol agents

Save Palm Trees from Weevil Devils

April 29th, 2008 Posted in Biological Control

In nature there are some predators like earwigs which feed on the loose eggs. However, there are no biocontrol agents capable of reducing the pest population. Several laboratories have tested and tried to introduce biocontrol agents like entomopathogenic nematodes, fungal pathogens etc., but with very little success.
