Chemical identification, electrophysiological and behavioral activities of the pheromone of Metamasius hemipterus (Coleoptera: Curculionidae).
Five hydroxylated aliphatic molecules were identified as the pheromone produced by male West Indian Sugarcane Borer (WISB): 4-methyl-5-nonanol (1), 2-methyl-4-heptanol (2), 2-methyl-4-octanol (3), 5-nonanol (4) and 3-hydroxy-4-methyl-5-nonanone (5). Electroantennographic recordings revealed antennal responses to compounds 1, 2, 3 and 4. Significant EAGs were also recorded in response to pheromone compounds of weevils belonging to the same subfamily and structurally related to the WISB pheromone. The natural pheromone elicited aggregation behavior on WISB adults in laboratory bioassays.
