TACAIN, Jimena et al. Synthesis and Field Evaluation of the Sex Pheromone of Plutella xylostella (L.) (Lepidoptera: Plutellidae) in Canola (Brassica napus L.). Agrociencia Uruguay [online]. 2016, vol.20, n.2, pp.61-67. ISSN 1510-0839.

The diamondback moth Plutella xylostella (L.) is known to cause economic damage to rapeseed, cabbage, and other cruciferous crops worldwide. Sex pheromone components of P. xylostella, including (Z)-11-hexadecenal, (Z)-11-hexadecenol, and (Z)-11-hexadecenyl acetate, were synthesized in a concise and divergent fashion in yields appropriate to develop field tests. Two blends were prepared from these three components (8:18:100 and 10:1:90), and they were used to evaluate the number of P. xylostella adult male captures in commercial canola fields. Our results indicate that both blends were effective at attracting the microlepidoptera. Furthermore, they show that this type of pest-specific method could lead to the development of sustainable management strategies to rationalize the use of pesticides.
