Visual Diagnosis of the Varroa Destructor Parasitic Mite in Honeybees Using Object Detector Techniques

Sensors, 2021
The Varroa destructor mite is one of the most dangerous Honey Bee (Apis mellifera) parasites worldwide and the bee colonies have to be regularly monitored in order to control its spread. In this paper we present an object detector based method for health

Rapid hormonal rise in honey bees due to heat‐shock is mitigated by a primer pheromone

Insect Science, EarlyView.
We show that honey bee foragers increased juvenile hormone (JH) titers significantly after heat‐shocked for 1 h at 40 °C, but this increase is dependent on social conditions. Increase of JH titers only happened when bees were isolated (one worker bee per vial) but not in groups.

Nationwide Tracking of A‐Lineage Spread in Western Honey Bees Using Haplotype Sharing, Local Ancestry Mapping, and Migration Inference

Ecology and Evolution, Volume 16, Issue 11, November 2026.
This study investigates the spatial spread and genetic impact of A‐lineage (Africanized) ancestry in U.S. honey bee populations using a large, community‐science genomic dataset. By applying RFMix and TreeMix, we reveal strong northward gene flow originating from southern states such as Texas, Arizona, and Florida into northern regions, with high ...

Examining the factors influencing Varroa destructor host selection of Apis mellifera larvae [PDF]

, 2018
The European honey bee, Apis mellifera, is a vital species for agriculture, providing pollination for crops all around the world. Recent declines in honey bee health have been concerning, and the spread of the ectoparasitic mite Varroa destructor is ...

Environmental DNA Methods for Detection of Varroa destructor in Honey Bee (Apis mellifera) Hives

Environmental DNA
The parasitic mite, Varroa destructor, is a worldwide problem for honey bees (Apis mellifera). The recent spread of this pest to Australia, which was one of the few varroa‐free honey bee populations remaining, highlights the importance of effective ...

Honey bee populations surviving Varroa destructor parasitism in Latin America and their mechanisms of resistance

Frontiers in Ecology and Evolution
The honey bee (Apis mellifera) parasitic mite, Varroa destructor, is considered one of the main causes of colony losses in European honey bee (EHB) populations around the world.

Stable Reference Genes for RT‐qPCR in House Dust Mite Dermatophagoides farinae (Acari: Pyroglyphidae) at Different Developmental Stages

Ecology and Evolution, Volume 16, Issue 11, November 2026.
First systematic evaluation of reference genes across different developmental stages of Dermatophagoides farinae. RPL18 and RPS28 are identified as the two stable reference genes. Cytochrome P450 3A8 gene validates that these stable reference genes provide robust and consistent expression patterns.

The Future of Native Bees in Australia Under Environmental and Anthropogenic Change

Ecology and Evolution, Volume 16, Issue 10, October 2026.
Bees are considered one of the most important and abundant pollinators across the globe, yet they are under threat from anthropogenic activities such as land‐clearing, urbanisation, agricultural activities, pesticide use, non‐native flora and fauna introductions, disruption of natural fire regimes, pollution and climate change, among others.

An amino acid substitution (L925V) associated with resistance to pyrethroids in Varroa destructor. [PDF]

, 2013
The Varroa mite, Varroa destructor, is an important pest of honeybees and has played a prominent role in the decline in bee colony numbers over recent years.
