SUMMARY:

Growing food efficiently and sustainably is a matter of great relevance and enormous
repercussion in society. A current crop pest control strategy is using synthetic pheromones based on a safe
environmental management approach. The present work consists of the synthesis of sex pheromones and
candidate molecules for pheromones of the main insect pests of soybean (Chrysodeixis includens), cashew
(Anacampsis phytomiella), apple (Bonagota salubricola), coffee (Leucoptera coffeella) and açaí (Ozopherus
muricatus). Economic and promising synthesis methodologies are proposed to obtain these pheromones.
The (Z)-7-dodecenyl acetate (C. includens) and 5,9-dimethylpentadecane (L. coffeella) were obtained with
overall yields of 54% and 15%, respectively. In the synthesis of (3E,5Z)-dodecadienyl acetate (B.
salubricola) the key intermediate, (Z)-5-dodecen-3-yn-1-ol, was obtained in 53% overall yield. Studies
related to the identification of semiochemicals from A. phytomiella and O. muricatus were carried out by the
research group, LPqRN, indicating candidate molecules for pheromones from these pests, the (Z)-7,9-
decadienyl and (Z)-9,11-dodecadienyl acetates, indicated for A. phytomiella were synthesized with yields of
39% and 42%. For O. muricatus the suggested molecules, 3-nonanone and 3-methylheptane, were obtained
with yields of 79% and 59%, respectively.
