An endangered species of aquatic beetle, known as the Comal Springs riffle beetle, inhabits just two spring systems in Texas and is at the center of ongoing protection efforts. A new study offers important insight into how to rear the species in captivity for conservation.
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.
