Research on the rate at which mosquitoes land on people in field tests and lab tests finds that common arm-in-cage test results differ significantly from those found in large-room or field tests. The findings point the way toward making tests of mosquito repellents more aligned with real-world conditions.
A new study digs into the pros and cons of two different methods for testing potential bed bug repellents: a harborage test and a barrier test. Repellency results can differ when bed bugs are searching for shelter versus when they are searching for a bloodmeal.
Researchers discovered a potential repellent for walnut twig beetles when they ran out of one adhesive for sticky traps and switched to another, and suddenly the beetles were no longer attracted to the traps.
New research from the U.S. Centers for Disease Control and Prevention shows that DEET and other repellents approved by the EPA for use against native ticks are also effective against the invasive Asian longhorned tick (Haemaphysalis longicornis).
A study on the durability of permethrin-treated clothing found that, after 16 cycles of wearing and washing the clothes, their repellent effect on ticks was indeed reduced, but it was still better than untreated clothing.
