Commonly Used Acaricides Found Effective on Invasive Tick

The Asian longhorned tick (Haemaphysalis longicornis), an invasive species in the U.S., is a threat to cattle and other livestock. A new study finds several pesticides used to manage other tick species are equally effective against the new arrival.

Inducing Mosquitoes to Lay Eggs Aids in Insecticide Resistance Testing

Testing field-caught mosquitoes for insecticide resistance is a critical effort in the fight against malaria and other vector-borne diseases. Researchers in Thailand say a "forced oviposition" method has proven successful in inducing field-caught Anopheles mosquitoes to lay eggs and spawn lab populations big enough for insecticide-resistance testing.

Crowdsourced Photos Show Expanding Ranges for Ticks

Analysis of tick photos submitted to the TickSpotters program finds three tick species that transmit Lyme and other human diseases are present in hundreds of U.S. counties where previous surveillance had not yet documented them.

How Florida Mosquito Control Could Trim Disease in Northern States

Researchers in Florida have pinpointed the local overwintering habitats of mosquitoes that host eastern equine encephalitis virus. They hope targeted control efforts can cull those mosquitoes before they transmit the virus to birds that carry it north to other parts of the country.
