American palm weevil Rhynchphorus

Some esters of long-chain saturated fatty acids are aggregation pheromone beetles. The ethanol-ester of 4-methyloctanoic acid is, for instance, a commercialized aggregation pheromone (Oryctalure ) used to control the coconut rhinoceros beetle (Oryctes rhinoceros) (Morin et al., 1996). American palm weevil (Rhynchphorus palmarum) is attracted by the aggregation pheromone 6-methyl-2-hepten-4-ol. The pheromone has been tried for control of the weevil and is sold under the names Rhyncopherol and Rhynkolure .
