Control
The main control method is through the application of a systemic insecticide. Insecticide is usually applied through a funnel about 5 cm above the infested area of the trunk. The red palm weevil can be monitored using pheromone lures bucket or pitfall traps, and alternative forms of control use field sanitation and mass trapping with traps baited with pheromone and plant derived semiochemicals. New alternative technologies using semiochemicals and bio insecticides are being developed to more effectively control this devastating pest of palm trees. One of them is a new formulation with insecticide and pheromone called SPLAT RPW that attracts the weevils to a point source and kills them. Another ecofriendly management technique is to drench the base of palm fronds with the entomopathogenic fungus Metarhizium anisopliae, or Beauveria bassiana. An Italian company has developed a microwave collar that can be used to sterilize individual trees.

We hang on to him, begging him to teach us how to do whatever is masculine, to throw balls or be in the woods or go see where he works. . . . We want our fathers to protect us from coming too completely under the control of our mothers. . . . We want to be seen with Dad, hanging out with men and doing men things.”
—Frank Pittman (20th century)
“The basic tool for the manipulation of reality is the manipulation of words. If you can control the meaning of words, you can control the people who must use the words.”
