Resumo: The cotton boll weevil, Anthonomus grandis Boheman, 1843 (Coleoptera: Curculionidae) is the main insect-plague in the cotton crop. The use of pheromones in the fight against insects has been won every time the space is biodegradable, it is not allowed to accumulate in the environment, besides the specificity to the target insect. These compounds are two (+)-cis-2-isopropenyl-1-methylcyclobutane-ethanol and (Z) -3,3-dimethylcyclohexylidene-ethanol alcohols, and two aldehydes, (E) -3,3-dimethylcyclohexylidene- acetaldehyde and (Z) -3,3-dimethylcyclohexylidene acetaldehyde which were subsequently named grandlure I, II, III and IV. For grandlure I, intermediates 1, 2, 3 and 11, key precursors for their synthesis, were obtained. Grandlures II, III and IV were successfully obtained with reproducibility and quantitative yields. Chitosan beads have efficiently released molecules with different chemical functions like pheromones and drugs. The pheromones of Rynchophorus palmarum and Metamasius hemipterus when incorporated into reticulated chitosan beads had a slow and controlled release with efficient kinetics. The field time of the traps containing the pheromones incorporated into the chitosan beads to capture these pest insects was higher than the pheromones currently in use.
