NEW TECHNOLOGY IN HAND-APPLIED PHEROMONE DISPENSERS FOR ORIENTAL FRUIT MOTH DISRUPTION
 

Summary: NEW TECHNOLOGY IN HAND-APPLIED PHEROMONE DISPENSERS
FOR ORIENTAL FRUIT MOTH DISRUPTION
2004

This trial was conducted in mixed plantings of fresh and processing apples on six commercial
farms in Wayne and Ontario Counties, NY. A low-density pheromone "bag" dispenser was
compared against two types of "twist-tie" dispensers for efficacy in suppressing pheromone trap
catches of oriental fruit moth (OFM), Grapholita molesta, when applied against the 2nd and 3rd
generations of this pest. Apple varieties included Gala, R.I. Greening, Golden Delicious, Red
Delicious, Monroe, Ida Red, Empire, and McIntosh.
Materials & Methods
The pheromone bag treatment, termed "MSTRS" technology (Metered Semiochemical
Timed Release System, AgBio Inc., Westminster, CO) consisted of food-grade plastic enclosing
a 6.4 x 6.4 cm natural fiber pad containing 65.8 g of OFM pheromone (85.4 : 5.5 : 0.9% of
Z:E8-12:OAc : Z8-12:OH), which was deployed in a grid pattern at a spacing of 22.9 m (75 ft)
between dispensers, resulting in densities between 1120 per ha (5.28.0 per acre). A pole+hoop
applicator was used to position the dispensers in the top one-third of the tree canopy; deployment
took place from 913 July.
