Goals / Objectives
Determine the effectiveness of 2 rates of ammonia hydroxide released from dry and wet traps. Determine the effectiveness of sugar-derived baits alone and in combination with ammonia baits in dry traps. Determine populations of apple maggots among 3 regions and habitat types in western Washington by using these dry and wet traps. Relate trap captures to food abundance in the environment over the season. Determine reproductive status of trapped flies over the season.
Project Methods
Ten types of traps will be used i nthe study. Four will be design to test the effects of low and high ammonium hydroxide release rates on attracting flies. Two will be yellow rectangle sticky traps (dry traps) baited with the 2 rates of AH. AH will be released from dispensers placed next to the traps. Flies attracted to the trap encounter the sticky adhesive placed on the trap and are captured. The other 2 traps will be similar to the McPhail trap. Two rates of AH will be released from the water in the bottom of the trap. Flies attracted to the trap fall and drown. Trap-AH treatments will thus be (1) rectangle low AH, (2) rectangle high AH, (3) wet trap low AH, and (4) wet trap-high AH. Traps will be checked once a week, flies and adhesive removed, and trap materials replaced at these times. Documents Trust with WTFRC. Log 19018. Formerly 5352-22000-013-24T, 03/03.

Outputs
4. What were the most significant accomplishments this past year? This report serves to document research conducted under a Trust agreement between ARS and Washington Tree Fruit Research Commission. Additional details of research can be found in the report for the parent project, 5352-22000-015-00D, Research/Management of Insects and Tree Fruit. We determined that apple maggots are more attracted to ammonia than fruit volatile lures, as long as the ammonia release rate is 1-5 mg/h. This helps growers by identifying a strong trapping system that can be used to detect flies and prevent the establishment of lies near apple growing areas.
