Genetic Allee Effects for Controlling Invasive Populations

Molecular Ecology, Volume 35, Issue 1, January 2026.
ABSTRACT Invasive pests threaten food security and devastate ecosystems. A universal problem in their management is that small populations can easily evade detection. This makes identifying new incursions challenging and complicates efforts to eradicate or contain established populations.

Characterization of Prophenoloxidase in Resisting Adverse Stresses in Apis cerana cerana [PDF]

Journal of Environmental Analytical Chemistry, 2015
Insect prophenoloxidases (PPOs) are a group of important innate immunity proteins and play an important role in melanin synthesis, defending the intruding microorganisms and parasites, healing wound and cuticle pigmentation. However, there is little study about immune-related defense mechanisms in Apis cerana cerana. Here we isolated a PPO gene from A.

Fending for Thyself: Honey Bees From Ethiopia Inflict Physical Damage on Varroa destructor

Ecology and Evolution, Volume 15, Issue 12, December 2025.
This study assessed grooming and hygienic behaviors of Apis mellifera simensis in Ethiopia's Amhara region across landscapes and seasons. Despite Varroa mite levels occasionally exceeding economic thresholds, bees maintained low infestations through strong social immunity traits, suggesting natural tolerance rather than resistance.

Ecotoxicological effects of common fungicides on the eastern honeybee Apis cerana cerana (Hymenoptera)

Science of The Total Environment, 2023
The widespread use of fungicides for plant protection has increased the potential for pollinator exposure. This study therefore aimed at assessing the acute and chronic effects of fungicides on pollinators. For this purpose, the acute oral toxicity of the common fungicides azoxystrobin, pyraclostrobin, and boscalid to Eastern honeybee Apis cerana ...

Study on Floral Syndrome and Breeding System of an Endangered Species Rhododendron nymphaeoides

Ecology and Evolution, Volume 15, Issue 12, December 2025.
This study divided the flowering process of Rhododendron nymphaeoides into five periods and systematically investigated the floral traits, pollen morphology and viability, optimal solid media for in vitro pollen germination, storage temperature screening, pollen–ovule ratio and hybridization index, stigma receptivity, the effects of different ...

Toll receptor ligand Spätzle 4 responses to the highly pathogenic Enterococcus faecalis from Varroa mites in honeybees.

PLoS Pathogens, 2023
Honeybees play a major role in crop pollination, which supports the agricultural economy and international food supply. The colony health of honeybees is threatened by the parasitic mite Varroa destructor, which inflicts physical injury on the hosts and ...

Global variation in honey bee (Apis mellifera) mating flight times

New Zealand Journal of Zoology, Volume 52, Issue 5, Page 830-843, December 2025.
ABSTRACT During the mating season, male (drone) honey bees (Apis mellifera L.) make daily flights to drone congregation areas (DCAs) for the purpose of mating with a virgin queen. The timing of these flights (drone flight period) varies between geographic regions. However, the spatial scale over which variation occurs and the mechanisms contributing to
