United We Stand Meeting is a Success!  

Last week, 75 business owners from North Carolina and surrounding states attended the United We Stand, United We Grow Meeting at the Grandover Resort in Greensboro, NC. This meeting was facilitated by pest management experts from across the country discussing ways to improve their businesses for the new year. Thank you to our sponsors, speakers, and attendees for making this a successful event!

Penn Study Shows Bed Bugs Can Transmit Parasite that Causes Chagas Disease 

The bed bug may be just as dangerous as its sinister cousin, the triatomine, or "kissing" bug. A new study from Penn Medicine researchers in the Center for Clinical Epidemiology and Biostatistics demonstrated that bed bugs, like the triatomines, can transmit Trypanosoma cruzi, the parasite that causes Chagas disease, one of the most prevalent and deadly diseases in the Americas.

Evaluation of Fungal Spores Against Bed Bugs

Over the last decade there has been a growing interest in the use of biological control agents against structural insect pests. A group of scientists from University of Maryland-College Park and USDA, led by Kevin Ulrich, recently evaluated the use of fungal spores, Metarhizium anisopliae, against the bed bugs, Cimex lectularius, in the lab. The entomopathogenic spores, which have been effective against other true bugs, were introduced to the pyrethroid-susceptible bed bugs in a variety of ways, including feeding, contact, and by aerosol spray. Unless humidity levels were exceptionally high (98%), the only delivery method that effectively caused mortality was ingestion, when spores were mixed with a blood product and fed to bed bugs. Ambient humidities in structures are typically much lower than that so the authors of the study concluded that M. anisopliae is not an effective control strategy, at least not in the ways tested in these experiments. However, previous studies have shown another fungus (Beauveria bassiana) to be effective against bed bugs.

This research was published in the most recent volume of the Journal of Economic Entomology under the title, "Exposure of Bed Bugs to Metarhizium anisopliae at Different Humidities".

Evaluating Ant Treatment Protocols  

A new collaborative study between entomologists at the University of California - Riverside and two pest management firms evaluated two treatment protocols for their efficacy against Argentine ants (Linepithema humile) and their subsequent environmental impact. The authors of this study, led by Dr. Les Greenberg, developed two protocols, one bimonthly and the other monthly, that both began with a foundation treatment with a fipronil spray, though they were differentiated with additional treatments. The first protocol (bimonthly) supplemented fipronil with bifenthrin granules applied away from impervious surfaces and spot treatments with a cyfluthrin spray. The second protocol (monthly) also included spot treatments with cyfluthrin but also made prominent use of a botanical insecticide. Ant numbers around the test structures were recorded and no significant differences were found between the two protocols.

This paper was published in a recent volume of the Journal of Economic Entomology under the title, "Practical Pest Management Strategies to Reduce Pesticide Runoff for Argentine Ant (Hymenoptera: Formicidae) Control".
