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.
Ophiogomphus howei, the smallest dragonfly of its genus and known to inhabit ranges primarily in Appalachia and Wisconsin in the United States, has been discovered by Odonata enthusiasts in southern Michigan, in a setting that may prompt a rethink of the species' habitat preferences.
Entomologists studying ticks and the disease pathogens they carry must also become adept at handling the host animals that ticks feed on, such as mice. A new article in the open-access Journal of Insect Science offers a guide to do just that, part of a new special collection on protocols in medical and veterinary entomology.
A new study finds that reduced water availability—even if not quite drought conditions—lessens the quality of floral resources for honey bees and bumble bees, in turn negatively affecting their survival and reproduction rates.
A recent review in the open-access Journal of Insect Science shines a light on the diversity of host-symbiont relationships among holometabolous insects.
