The Vulnerability of New Zealand Forage Plants to Incursions by New Pests, Pathogens and Weeds, and the Case for Greater Protection

New Zealand Journal of Agricultural Research, Volume 69, Issue 1, February 2026.
We outline the diversity of pests, weeds and plant pathogens absent from New Zealand that threaten forage production, examine their potential import pathways, and outline the challenges of managing them should they arrive. The number and diversity of threats and pathways indicates ongoing incursions are inevitable.

So near and yet so far: Harmonic radar reveals reduced homing ability of nosema infected honeybees [PDF]

, 2014
Pathogens may gain a fitness advantage through manipulation of the behaviour of their hosts. Likewise, host behavioural changes can be a defence mechanism, counteracting the impact of pathogens on host fitness.

Pathogenesis, Epidemiology and Variants of Melissococcus plutonius (Ex White), the Causal Agent of European Foulbrood

Journal of Apicultural Science, 2020
The bacterium Melissococcus plutonius is the etiologic agent of the European foulbrood (EFB), one of the most harmful bacterial diseases that causes the larvae of bees to have an intestinal infection.

Short Communication: Efficacy of Two Commercial Disinfectants on Paenibacillus larvae Spores

Frontiers in Veterinary Science, 2022
Paenibacillus larvae is a spore-forming bacterium causing American foulbrood (AFB) in honey bee larvae. The remains of a diseased larva contains billions of extremely resilient P. larvae spores viable for decades.

Paenibacillus larvae Chitin-Degrading Protein PlCBP49 Is a Key Virulence Factor in American Foulbrood of Honey Bees [PDF]

, 2014
Paenibacillus larvae, the etiological agent of the globally occurring epizootic American Foulbrood (AFB) of honey bees, causes intestinal infections in honey bee larvae which develop into systemic infections inevitably leading to larval death.

Honey Bee Colony Health in Thiamethoxam‐Treated Sugar Beet Fields: A Field‐Based Case Study

Ecology and Evolution, Volume 15, Issue 12, December 2025.
Using multi‐site field trials during Germany's 2021 emergency authorization of thiamethoxam‐treated sugar beet, we combined colony demography and residue analyses with complementary worker survival assays to characterize honey bee exposure under realistic conditions.

The Honeybee Disease American Foulbrood — An African Perspective [PDF]

African Entomology, 2011
Sustaining apiculture worldwide has been threatened by bee diseases and unexplained colony losses. African honeybee populations seem healthier and no major losses have been reported despite the presence of all the major pests and diseases. The scattered colonies in the large wild population of the continent might ensure slow pathogen spread and thus ...

The Foster method: Rapid and non-invasive detection of clinically significant American Foulbrood disease levels using eDNA sampling and a dual-target qPCR assay, with its potential for other hive pathogens

bioRxiv, 2021
Clinical signs of American Foulbrood (AFB) can be difficult to diagnose and thus disease is often missed and leads to further spread. Diagnosis is centred on the beekeeper’s skill in recognising clinical symptoms – a highly subjective and time-consuming ...
