| Résumé : | Synthetic sex pheromone of the pea moth Cydia nigricana, (E,E)-8,10- dodecadien-1-yl acetate (E8,E10-12:Ac), was applied in polyethylene dispensers at a rate of 30 g/ha and 600 dispensers/ha in a 0.6-ha pea field. The release rate of E8,E10-12:Ac was 140 mg/ha/day after six days, and 82 mg/ha/day after 20 days. Aerial concentrations of E8,E10- 12:Ac, as measured by a portable EAG apparatus, ranged from 2 +ou-2 to 7 +ou-3 ng/m**(3). The antennal signal was high and rather constant within pea canopy, but was lower and fluctuated strongly above canopy. Initially, >99% isomerically pure E8,E10-12:Ac was released, and male moths were attracted to dispensers |
