Non Technical Summary
Black cherry is the most valuable northern hardwood. Peach bark beetle has the potential to cause significant degrade in cherry lumber and veneer. The basic purpose of this project is to develop pest/forest management recommendations to minimize the economic impact of peach bark beetle on black cherry lumber and veneer.

Goals / Objectives
Investigate the bionomics of peach bark beetle, including its life history, natural enemies, reproductive potential and life system requirements. These data will be compared to that from studies done in commercial peach orchards. Ultimately our purpose is to describe susceptible site and stand conditions and this information, in turn, will be used to make forest management recommendations.

Project Methods
1. The distribution and abundance of peach bark beetle will be determined by examining 100 plus stands randomly selected across NY State and data from a similar number of stands in PA. Gum spot counts on standing trees will serve as a surrogate for beetle density. Density will be related to a range of site and stand conditions. Black cherry will be felled and dissected to determine the relation between number of gum spots and actual beetle numbers. 2. Black cherry slash will be examined weekly throughout the season to determine the seasonal occurrence of all life stages, number of generations per year and natural enemies. Seasonal development will be examined in the context of temperature as recorded in each of two stands with Hobo data recorders. The intent here is to develop a degree day model for emergence and seasonal development. 3. Seasonal activity of adults will be studied using Lingren funnel traps baited with ethanol lures at a release rate of 1000mg/day using Hercon Vapotape II as a killing agent. Traps are emptied twice a each week from May through September. 4. Fresh slash will be created monthly in each of two stands to provide breeding material and to determine the suitability of cherry slash created during different months.

Outputs
OUTPUTS: The information obtained from this project has been shared with the PA DCNR, NY DEC and forest owners in NY. This was accomplished through field visits with state forestry personnel, articles in a publication of the NY Forest Owners Association and posters presented at SAF annual meetings for NY and New England. Finally, it was presented in a talk given to the annual meeting (training session)of PA DCNR foresters, forest protection specialists, and representatives of forest industry. PARTICIPANTS: Douglas C. Allen, Distinguished Professor, College of Environ. Sci. and Forestry, 1 Forestry Drive, Syacuse, NY 13210 Joshua Bogart (MS student) Collaborated with foresters in the NY DEC and PA DCNR provided training for annual meeting of PA DCNR Forestrers and Forest Health specialists. TARGET AUDIENCES: Forest Owners in NY, State and consulting foresters in NY and PA

Impacts
Resources provided by this grant supported a graduate student (MS), provided travel funds for research and information dissemination. It also provided travel opportunities to work with PA foresters in their infested stands. Results described the biology of PBB (e.g.,. fecundity, number of generations/year, number and temporal occurrence of larval instars, adult flight activity) in northern NY and PA, which differs from that reported in OH and WV. The life cycle is described in detail and, combined with results from a project dealing with the temporal occurrence of cutting in black cherry stands (in progress), will help to define a "siviclutural window" when cherry can be cut (and slash or breeding material is created) and damage to standing cherry by overwintering beetles will be minimized.

Progress 10/01/03 to 09/30/04

Outputs
The life history and general biology of peach bark beetle has been studied in black cherry as a component of northern hardwood and allegheny hardwood stands in NY State. In general,its biology under these conditions appears to be similar to peach bark beetle in commerical cherry and peach orchards. This work is still in progress, however, and detailed results will not be available until spring 2005.

Impacts
A better understanding of the interaction between this bark beetle and black cherry is a first step in defining silvicultural recommendations for control or for minimizing damage.
