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.
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.
When fly larvae are collected from a corpse at a crime scene, they still need to eat so they can be raised to adulthood and identified to species. A new study says a simple can of tuna could be an easy and cost-effective solution for keeping the larvae alive until a forensic entomologist can conduct analysis.
The Kamehameha butterfly, once widespread across its native Hawai'i, has been displaced by human incursion to its habitat. The Hawai'i Invertebrate Program is on a mission to bring the butterfly and its host plants back to their former glory.
The mosquito species Toxorhynchites rutilus is harmless to humans but is a voracious predator of other mosquitoes. Researchers in Houston, Texas, are hoping the "mosquito assassin" could be put into action as a tool for controlling mosquitoes that carry human pathogens—if they can find an efficient way to raise the predator mosquitoes in the lab.
