Quote: “Our results show that human transport of infested materials is a significant risk for spreading populations of invasive conehead termites,” Thorne says. “The operational application of this result is that, beginning immediately upon discovery of invasive coneheads (or any species in the genus Nasutitermes), alerts and precautions must be implemented to prevent movement of potentially infested materials to a new location.” Read full article here>>

The findings show that managing roadsides via selective herbicide use (SH) and annual fall mow (fall mow) can significantly increase floral diversity and bee abundance compared to a traditional frequent mowing (turf) regime. While differences between treatments – SH and fall mow – were detected, they were not significant. Bee diversity, which accounts for both abundance and the evenness of species in a given area, was mainly determined by site/surrounding landscape not treatment and was the sole significant factor. Given that floral abundance and diversity, as well as bee abundance, were increased under SH and fall mow compared to turf plots, both Integrated Roadside Vegetation Management (IRVM) practices have shown great potential in supporting pollinators.
The final report can be read here>>  Photo Credit: CMNS Congratulations to the vanEngelsdorp Lab for their work on the 13th Annual Honey Bee Loss Survey. The 13th Annual BIP Honey Bee Colony Loss Survey was released in June. The survey showed that U.S. beekeepers lost almost 40% of their bee colonies last winter, the largest loss recorded in 13 years. Researchers are using this data to establish best management practices that will help beekeepers improve the health of bees.

Their study tested the effectiveness of genetically modified fungus in controlling malaria-carrying mosquitoes outside a laboratory. Their tests demonstrated that the transgenic fungus caused mosquito populations to drop below viable levels within two generations.
