Non Technical Summary
The lesser mealworm, litter or darkling beetle, Alphitobius diaperinus (Panzer) (Coleoptera: Tenebrionidae), is a major pest in Arkansas and other poultry producing states. Producers rely primarily on insecticides to manage populations of this pest. Outcome from this project may result in the addition of a new chemistry to use in litter beetle management.

Goals / Objectives
To evaluate the efficacy of candidate insecticide formulations against infestations of larval and adults darkling beetles (Alphitobius diaperinus) in the litter of commercial broiler houses.
Project Methods
Larval and adult litter beetle populations will be estimated to determine the pest population and evaluate insecticide efficacy. Sampling will consist of collecting 13 core litter samples in each broiler houses. Litter samples will be taken immediately following bird removal, and at 7, 21, 35, 49 and 56 days after a new flock is placed into the houses. Immediately following litter collections, samples with be taken to the lab and sorted. Numbers of adult and larval litter beetles will be recorded and statistically analyzed to determine efficacy and significant differences between treatments. Candidate insecticide(s) will be applied to empty houses seven days prior to placement of the new flock. Applications will be made similar to guidelines used for other insecticides.

Outputs
OUTPUTS: Studies initiated in 2007 to evaluate potential alternative insecticides to manage the darkling beetle, Alphitobius diaperinus were expanded upon and completed in 2010. Results identified one insecticide alternative at the proposed label rate and method of application as effective in managing adult and larval Alphitobius diaperinus. Subsequently, this product received labeling and approval from EPA for management of this pest. Efficacy studies in 2010 identified an additional EPA registered product. This registered product demonstrated efficacy was added to the Poultry Control Section of the "2011 Insecticide Recommendations for Arkansas". This publication (or MP 144) is made available from the University of Arkansas Cooperative Extension Service through a web site and hard copy through various units of the University of Arkansas. PARTICIPANTS: Producers, Integrator TARGET AUDIENCES: Poultry Producers, Intergrators PROJECT MODIFICATIONS: Nothing significant to report during this reporting period.

Impacts
Results from a 2008 study in Arkansas and other cooperating states demonstrated efficacy of an imidacloprid product. Combined efficacy data resulted in EPA labeling of this product. Studies initiated in 2010 identified an additional registered insecticide and an experimental insecticide combination that could prove useful in darkling beetle management. Results indicated that these products were equal in efficacy to insecticides currently used by Arkansas poultry producers. Results from 2010 Alphitobius diaperinus management studies and review of current literature provided data to support use of an additional insecticides for management of darkling beetles and revision of the "2011 Insecticide Recommendations for Arkansas" to include additional insecticides. The "Insecticide Recommendations for Arkansas" (MP 144) positively impacts poultry integrators and producers by disseminating information on the most recent advances in insecticides and options available for Alphitobius diaperinus management. Arkansas has approximately 7,000 poultry producers and ranks number 2 in the U.S. for broiler production. Poultry accounts for almost 40% of Arkansas agriculture. Darkling beetle (adults and larvae) are potential reservoirs of poultry pathogens, their larvae destroy insulation in poultry houses, and adults are a nuisance as they migrate to nearby residential housing during litter clean-out. Because of these issues darkling beetles are a major pest in Arkansas production. New management options provide additional tools to Arkansas poultry producers for effective darkling beetle management.

Outputs
OUTPUTS: Studies initiated in 2007 to evaluate potential alternative insecticides to manage the darkling beetle, Alphitobius diaperinus were completed in 2008. Results identified one insecticide alternative at the proposed label rate and method of application as effective in managing adult and larval Alphitobius diaperinus. Subsequently, this product received labeling and approval from EPA for management of this pest. Following EPA approval, the insecticide was approved by the Arkansas State Plant Board for use in Arkansas poultry production. Review of efficacy data and insecticide labels of products available to manage Alphitobius diaperinus in poultry facilities were used to make several revisions to the Poultry Control Section of the 2009 "Insecticide Recommendations for Arkansas".

PROJECT MODIFICATIONS: Nothing significant to report during this reporting period.

Progress 01/01/07 to 12/31/07

Outputs
Studies were initiated in 2007 to evaluate potential alternative insecticides to manage the darkling beetle, Alphitobius diaperinus. Results identified alternatives that may provide benefit to the poultry industry. Additional studies will be conducted in 2008 and beyond to further evaluate these alternatives and their application rates and methods. Efficacy data and insecticide labeling of currently labeled products available to manage darkling beetles in poultry houses were reviewed and used to update the 2008 Insecticide Recommendations for Arkansas. Insecticide Recommendations for Arkansas are made available from the University of Arkansas Cooperative Extension Service through a web site and via a hard copy through various units of the University of Arkansas.

Impacts
Results from 2007 Alphitobius diaperinus management studies are too preliminary to positively impact poultry integrators or producers. However, the 2008 Insecticide Recommendations for Arkansas can positively impact poultry integrators and producers by disseminating information on the most recent advances in insecticides and management options available for Alphitobius diaperinus.
