Some plant volatiles act synergistically with aggregation pheromones. Aggregation of the American palm weevil, Rhynchophorus palmarum, on host plants is mediated by host-plant volatiles and a male pheromone (rhynchophorol).60 Acetoin, one of the major volatile components of the host plants Cocos nucifera, Saccharum officinarum, Jacaratia spp., and Elaeis spp., plays an important role in the aggregation of weevils on these plants. Although the pheromone alone is weakly attractive, its attraction is enhanced by acetoin.

CgHi O, Mr 128.21, oil, bp. 36-37°C (400Pa), (5)-enantiomer [a]n -11.0° (CHCI3). Aggregation pheromone produced by males of the African palm beetle Rhynchophorus palmarum that causes serious economic damage. First tests of R. as a pesticide in integrated plant protection were very promising see also weevils, pheromones. 

Lipase A (Amano, from Aspergillus sp.) was employed for the asymmetric hydrolysis of ( )-34 to give (S)-35, which was converted to the pheromone of the American palm weevil, Rhynchophorus palmarum (Figure 24.18) [21].
