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.

Famous quotes containing the word control:
“If someone does something we disapprove of, we regard him as bad if we believe we can deter him from persisting in his conduct, but we regard him as mad if we believe we cannot. In either case, the crucial issue is our control of the other: the more we lose control over him, and the more he assumes control over himself, the more, in case of conflict, we are likely to consider him mad rather than just bad.”
—Thomas Szasz (b. 1920)
“The human mind is indeed a cave swarming with strange forms of life, most of them unconscious and unilluminated. Unless we can understand something as to how the motives that issue from this obscurity are generated, we can hardly hope to foresee or control them.”
—Charles Horton Cooley (1864–1929)
“America is not so much a nightmare as a non-dream. The American non-dream is precisely a move to wipe the dream out of existence. The dream is a spontaneous happening and therefore dangerous to a control system set up by the non-dreamers.”
—William Burroughs (b. 1914)
