How an Invasive Species Spreads: The Case of Aedes notoscriptus in Southern California
First arriving in California in 2014, the mosquito species Aedes notoscriptus, native to Australia and the southwest Pacific, has since established and spread to 44 cities in three counties. A new study examines the public health implications of this species and documents its likely arrival and expansion routes.
The Promise—and Limits—of Bt Maize to Manage Fall Armyworm in Africa
As fall armyworm continues to threaten food security in Africa, the use of Bt maize offers significant potential to manage the pest. But it will be critical to manage resistance via multi-toxin crop varieties and appropriate use of refuge planting—all in forms accessible to the smallholder farmers that grow nearly all of Africa's maize.
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.
Need to Feed Mosquitoes? Head for the Freezer Aisle
In search of a simple, cost-effective way to maintain laboratory mosquito colonies, biologists at a mosquito control district in Florida have turned to food-grade frozen animal blood found at specialty grocery stores. They share the success of their new method for other cash-strapped mosquito-management operations in the open-access Journal of Insect Science.
