The document discusses updates to the Peanut Integrated Pest Management (IPM) program for 2010, focusing on pest detection and monitoring, including the efficacy of pheromone traps and the impact of weather on insect populations. It highlights significant insect outbreaks in 2009, such as armyworms and lesser cornstalk borers, while detailing research results and educational efforts to improve early detection systems for growers. Additionally, it covers new biological control strategies for thrips and other pests, alongside communication resources for pest management in Alabama.

3. Program objectivesResearch components:Efficacy of pheromone traps as a early detection tool (short-term)Impact of weather on insect abundance/activity (medium-term)Develop site-specific forecasting system (long-term)Educational components (based on needs assessment):Early warning system for growers/consultants/Agents (short-term)Increase adoption of pheromone traps (medium-term)Thrust to vegetable/peanut IPM via IPM-CORE (long-term)Funding (2009): Extension IPM Initiative, SPRI/NPB2010: Specialty Crops Block Grant, SPRI/NPB?, Ext IPM?

4. Insect monitoring project(new in 2009)Use traps for early detection of pests

5. What does trap catch tell you?Catch = pop. density x activity Trap network (operated by REAs): N-S: vegetable fields E-W: peanut fields Commercial traps/lures used

6. Trapping period: June-October

7. Trapping interval (2009): 14 daysWhy use pheromone traps?Generate information that you can use WITHIN SEASONKnow what to scout for & when to scout INTENSIVELYAutomatic identification of closely related speciesPrediction models will be avail.Stink bug trapWing trapPherocon trapBucket trap

8. Trap catches in 2009Insect catches (June-Oct.):Total = 8,586HighLesser cornstalk borer (LCB) = 3,586Fall armyworm (FAW) = 1,386Beet armyworm (BAW) = 1,377Corn earworm (CEW) = 589Southern armyworm (SAW) = 393Tobacco budworm (TBW) = 342Soybean looper (SL) = 230Cabbage looper (CL) = 223Corn rootworm (CRW): Southern = 253; Western = 13Black cutworm (BCW) = 125Stink bugs (SB, Euschistus) = 0*Low* Trap damaged at many locations** Traps added late (July-Oct.)
