Use of essential oils for controlling the Varroa destructor acarus in Apis mellifera

Pesquisa Agropecuária Tropical, 2012
The Varroa destructor (Acari: Varroidae) acarus is considered a major bee pest worldwide. The contamination risk of honey and wax, as well as the development of resistance by this pest, have led to the need of alternative ways for replacing conventional ...

ULTRASTRUCURAL STUDY OF BEE LOUSE VARROA DESTRUCTOR ANDERSON &TRUEMAN 2000 (ACARI: VARROIDAE) WITH RESISTANCE MODELS FROM APIS MELLIFERA L [PDF]

Journal of the Egyptian Society of Parasitology, 2015
The ectoparasitic mite Varroa destructor is the most dangerous pest of honeybee Egyptian race Apis mellifera L., as it causes many losses in apiculture worldwide. Adult female mites are flattened with a dome-shaped dorsal shield.

Gene‐specific double‐stranded RNAs induce mortality in the South African mealybug Delottococcus aberiae

Pest Management Science, Volume 82, Issue 6, Page 5184-5194, June 2026.
Gene‐specific double‐stranded RNAs effectively silence essential genes in the invasive citrus pest Delottococcus aberiae, leading to significant mortality through both microinjection and oral delivery. These results provide proof of concept for RNA interference‐based biopesticides as selective and sustainable tools for citrus integrated pest management.

Challenges for developing pathogen-based biopesticides against Varroa destructor (Mesostigmata: Varroidae)

Apidologie, 2012
Control of the major pest of apiculture, the ectoparasitic mite Varroa destructor using pathogen-based biopesticides would resolve many of the problems experienced with other forms of control, such as chemical control, hive manipulation, or selection of resistant honeybee strains.

Response of Amblyseius swirskii to deltamethrin

Pest Management Science, Volume 81, Issue 6, Page 2800-2811, June 2025.
The analysis of toxicological and molecular data reveals target‐site as well as metabolic modifications associated with the resistance to deltamethrin in Amblyseius swirskii colonies. However, semi‐field assays show increased run‐off behavior after treatments with the same pesticide.

An Insight Into the microRNA Profile of the Ectoparasitic Mite Varroa destructor (Acari: Varroidae), the Primary Vector of Honey Bee Deformed Wing Virus

Frontiers in Cellular and Infection Microbiology, 2022
The remarkably adaptive mite Varroa destructor is the most important honey bee ectoparasite. Varroa mites are competent vectors of deformed wing virus (DWV), and the Varroa-virus complex is a major determinant of annual honey bee colony mortality and ...

Deformed wing virus genotypes A and B do not elicit immunologically different responses in naïve honey bee hosts

Insect Molecular Biology, Volume 34, Issue 1, Page 33-51, February 2025.
We measured immune gene expression in DWV‐infected pupae in the absence of Varroa and found no evidence that DWV genotypes elicit a different immune response in honey bees. The antiviral siRNA response does not inhibit DWV from accumulating to high loads, with DWV siRNA response comparatively weaker than another honey bee virus, black queen cell virus (

Infestação do ácaro Varroa destructor em colônias de abelhas Apis mellifera L. em Teresina, Piauí. [PDF]

, 2023
O ácaro Varroa destructor (Anderson & Trueman) (Arachnida: Acari: Varroidae) é um ectoparasita que infesta abelhas Apis mellifera L. (Hymenoptera: Apidae) em todo o mundo, causa danos a crias e adultos e pode levar ao enfraquecimento e perda das colônias.
