Des diffuseurs à phéromones sexuelles de synthèse ont été installés en 1992 et 1993 dans trois vergers de pommiers (Malus pumila) du Québec, à raison de 1000 diffuseurs ha lors d'un essai de régie des populations de carpocapse de la pomme, Cydia pomonella [Lepidoptera : Tortricidae]. De 1991 à 1992, soit après un an d'essai, les dégâts de carpocapse à la récolte sont passés de 54 % à 32 %, de 11 % à 2 %, et se sont maintenus à 0 % dans les vergers à forte, moyenne et faible pressions de carpocapse, respectivement. Après deux ans d'essai, les dégâts sont demeurés au même niveau ou ont été diminués davantage selon le type de programme de répression utilisé contre les autres ravageurs. En 1993, une baisse de 75-100 % des captures a aussi été observée dans les pièges à phéromones par rapport aux captures observées en 1991.

Mating disruption of codling moth using codlemone pheromoneemitting twist-ties or cards has become a standard practice in many orchards. This study was initiated to determine the effectiveness of NoMate CM EC, a spray formulation of codlemone pheromone. Treatments were applied 20–21 Apr. 1995 to plots measuring 99 × 244 m of 15-year-old `Golden Delicious' apple trees on seedling rootstock. Trees were spaced 3.7 × 5.5 m and treatments were made in a randomized complete block design replicated three times. Whole trees were sprayed to run-off using a handgun. Treatments were 20.2 g a.i. NoMate CM EC/h and a watered sprayed control. Two pheromonebaited, sticky traps were placed in each replicate to monitor codling moth activity. Moth counts were made 3 days after treatment and continued twice weekly for 4 weeks. Results indicated very little moth activity for the first 14 days of the study in plots treated with NoMate CM EC when compared to the control. However, after the first two weeks differences between treatments were not significant.

Codling moth, Cydia pomonella (Lepidoptera: Tortricidae), is a phytosanitary pest of New Zealand’s export apples. The sterile insect technique supplements other controls in an eradication attempt at an isolated group of orchards in Hawke’s Bay, New Zealand. There has been no attempt in New Zealand to characterize potential sources of uncontrolled peri-urban populations, which we predicted to be larger than in managed orchards. We installed 200 pheromone traps across Hastings city, which averaged 0.32 moths/trap/week. We also mapped host trees around the pilot eradication orchards and installed 28 traps in rural Ongaonga, which averaged 0.59 moths/trap/week. In Hastings, traps in host trees caught significantly more males than traps in non-host trees, and spatial interpolation showed evidence of spatial clustering. Traps in orchards operating the most stringent codling moth management averaged half the catch rate of Hastings peri-urban traps. Orchards with less rigorous moth control had a 5-fold higher trap catch rate. We conclude that peri-urban populations are significant and ubiquitous, and that special measures to reduce pest prevalence are needed to achieve area-wide suppression and reduce the risk of immigration into export orchards. Because the location of all host trees in Hastings is not known, it could be more cost-effectively assumed that hosts are ubiquitous across the city and the area treated accordingly.
