| IPM Compatibility: |
Per Requester: Very Good Fit; Beauveria is non specific and dose dependent. No bee toxicity has been observed in preliminary hive treatments with high doses of Beuveria administered as a strip. No effect of hive health was observed with queens laying eggs and brood normal development. Commercial products are available with Beauveria for house fly and darkling beetle control in poultry houses. These products are used in the organic markets where insecticides are not allowed. For IPM programs, Beauveria can be used as a rotation product and due to being a biological, flexibility is use.

| Reasons for need: |
Varroa destructor, The varroa mite is an external parasite that attacks and feeds on honey bees adults and brood. Additionally, the mite carries diseases into the hives. A significant mite infestation results in the death of the hive. The economic threshold is considered to be around 3 to 5%, 3 to 5 mites per 100 bees.Resistance to chemical active ingredients leaves the beekeeper with few control options. Rotation to non chemical alternative provides the beekeeper with control options. Beauveria's mode of action of cuticle destruction allows for resistance to be difficult. Biological actives are also exempt from tolerance allowing flexibility is treatment:07/24; KY-Varroa resistance to other controls:06/25; NC-Varroa continues to be an economically important pest jeopardizing the honey bee industry. There are limited control options for this pest, which are showing resistance, and so more options are needed:06/25; CA:Beekeepers need additional tools to manage varroa mites. Use of biopesticides is encouraged minimize other potential negative effects from synthetic pesticides and minimizes possibility of resistance development:06/25;

| E/CS Research Comments: |
Performance and bee safety only, as A.I. is tolerance exempt. Efficacy data is needed to allow vetting via the IR-4 Biopesticide Regulatory Support program for regulatory support (Section 3 or label amendment for the an existing product balEnce, EPA Registration No. 70787-2). Beauveria bassiana Strain HF23, currently testing two formulations: one is a dust (applied via blower or over the top of bee frames) and one a liquid (which strips are dipped into to coat and placed in hives). Duration, method of application and reapplication interval to be finalized in 2025 field trials at OSU. PM 6/25
