The small hive beetle was first discovered in the United States in 1996 and has now spread to 27 U.S. states, including Hawaii. An infestation by small hive beetle was triggered in 2015 in British Columbia which led to a temporary quarantine. [11] In Mexico, the small hive beetle has become established in at least eight states.
The lifecycle of this beetle includes pupation in the ground outside of the hive. Controls to prevent ants from climbing into the hive are believed to also be effective against the hive beetle. Several beekeepers are experimenting with the use of diatomaceous earth around the hive as a way to disrupt the beetle's lifecycle. The diatoms abrade ...
African small hive beetle [ edit ] In a 2007 study by Megan Halcroft, A. australis successfully demonstrated its capability to defend against invasive African small hive beetles ( Aethina tumida ) that were intentionally introduced into the nest. [ 11 ]
The alarm pheromone has shown to be attractive to the small hive beetle. Therefore, there is a tradeoff between recruiting guards bees to defend the invaders and attract more beetles. The small hive beetle has a lower sensing threshold for the honeybee pheromone, which exacerbates the damage to honeybee hive. [39]
Deformed wing virus (DWV) is a positive-strand [1] RNA virus, one of 22 known viruses affecting honey bees.While most commonly infecting the honey bee, Apis mellifera, it has also been documented in other bee species, like Bombus terrestris, [2] thus, indicating it may have a wider host specificity than previously anticipated.

The brood of Western honey bees develops within a bee hive. In man-made, removable frame hives, such as Langstroth hives, each frame which is mainly occupied by brood is called a brood frame. Brood frames usually have some pollen and nectar or honey in the upper corners of the frame. The rest of the brood frame cells may be empty or occupied by ...
The world’s oldest known wild bird has sparked “special joy” among scientists after she laid an egg – her first in four years – at the age of 74.
