An eel donated to a natural history museum in 1873 had two ticks embedded in its skin, making it the first known instance of ticks parasitizing a fish. But it was only first documented this year, when a tick specialist identified the ticks and reported the case in the Journal of Medical Entomology.
Ticks on an Eel: Museum Specimen is a First of its Kind
Two ticks found on an 1873 electric eel specimen mark the first recorded case of ticks parasitizing a fish—but only documented just this year.

Rapid apple decline has afflicted orchards in several regions of the U.S. in recent years. A new study in North Carolina finds fungus-growing beetles are often associated with rapid apple decline, but they do not appear to be a primary culprit, and a variety of other factors are likely at play.
What Role, If Any, Do Ambrosia Beetles Play in Rapid Apple Decline?
A study in North Carolina finds fungus-growing beetles are often associated with rapid apple decline but do not appear to be a primary culprit driving the condition.

Since arriving in North America six years ago, the elm zigzag sawfly (Aproceros leucopoda) has spread across much of the northeastern U.S. and eastern Canada. A new study in the Journal of Integrated Pest Management documents its spread and reports a new host tree that the sawfly feeds on.

The small hive beetle is a pest of honey bees, but it can also be deployed in beneficial ways. New research shows small hive beetles can be reared on excess pollen in controlled settings, and their pupae and frass can be converted into animal feed and biomanure.
