Traces of Zika Found in Asian Tiger Mosquito in Brazil

aedes albopictus

In a recent test of Asian tiger mosquitoes (Aedes albopictus) collected in Brazil, researchers found fragments of Zika virus RNA, raising concerns that it may be carried by species other than Zika’s known primary vector, the yellow fever mosquito (Aedes aegypti). The research does not conclude that the Asian tiger mosquito can transmit Zika to […]

Mosquito Egg Hunt: Many Culex Species Prefer Alternatives to Standing Water

melanoconion mosquitoes eggs

The conventional wisdom about where many Culex mosquitoes lay their eggs—in standing water—is not always wise. Research into the diverse subgenus Melanoconion shows that many, if not most, mosquito species in the subgenus regularly lay their eggs on a variety of surfaces, and in a surprising location: above nearby water. The findings run counter to […]

Cimex latipennis

A cave in southern Oregon that is the site of some the oldest preserved evidence of human activity in North America was also once home to not-too-distant cousins of the common bed bug. In research published this week in the Journal of Medical Entomology, a pair of archaeologists describe remains found in caves near Paisley, […]

House Fly Death by Artificial Sweetener: Starvation, Not Toxicity

While recent headlines have noted the potential insecticidal properties of common artificial sweeteners, don’t go sprinkling Truvia around your home just yet. A new study on house flies suggests they likely aren’t poisoned by sweeteners—they just die of malnutrition. A team of researchers at North Carolina State University tested survival rates of house flies (Musca […]

Fossilized Tick Carrying Pathogens in Mammalian Blood Cells Discovered in 15-Million-Year-Old Amber

fossilized tick

Ticks have been pathogen-carrying parasites for a very, very long time. A new discovery in a specimen of fossilized amber, roughly 15 million to 20 million years old, reveals a tick encased adjacent to mammalian blood cells infected with microbes resembling those in the order Piroplasmida. Today, related pathogens are known to cause Babesiosis and […]
