Identification and field evaluation of the sex pheromone of a Brazilian population of Spodoptera cosmioides

摘要: The objective of this work was to identify the sex pheromone Spodoptera cosmioides and evaluate whether there is cross‑attraction in sp. (Lepidoptera: Noctuidae). gland extracts were analyzed by GC‑FID GC‑MS. Wind tunnel electrophysiology experiments conducted role compounds. In field, different traps tested: S. frugiperda commercial lure; (9Z)‑9‑tetradecenyl acetate (Z9‑14:OAc) (9Z,12E)‑9,12‑tetradecadienyl (Z9,E12‑14:OAc) trap; two females hexane control trap. Four acetates identified female as Z9‑14:OAc, Z9,E12‑14:OAc, (11Z)‑11‑hexadecenyl (Z11‑16:OAc) hexadecyl (16:OAc), but only first induced electrophysiological responses from male antennae. wind experiments, males responded more strongly conspecific blends; however, some cross‑attraction, 47% 25% heterospecific blends. field showed same response pattern observed bioassays. summary, components are Z9‑14:OAc Z9,E12‑14OAc; they important for conferring species specificity, pheromone-mediated cross attraction between .
