Bacterial Agents for Biocontrol of American Foulbrood (AFB) of Larvae Honey Bee

Microbiology Research
Bee colonies are constantly threatened by a bacterial larvae disease called American foulbrood, caused by the Gram-positive bacterium Paenibacillus larvae. This is a highly specialized pathogen with only one established host, the honey bee larvae.

Potential Use of Buddleja Thyrsoides for the Control and Prevention of American Foulbrood Disease in Honey Bees

Journal of Apicultural Science, 2014
Paenibacillus larvae is the causative agent of American Foulbrood (AFB ), a severe disease that affects the larvae of the honeybees. The use of plant extracts are considered to be an alternative way of controlling the disease. In this study, the in vitro

Transcriptional response of honey bee larvae infected with the bacterial pathogen Paenibacillus larvae. [PDF]

PLoS ONE, 2013
American foulbrood disease of honey bees is caused by the bacterium Paenibacillus larvae. Infection occurs per os in larvae and systemic infection requires a breaching of the host peritrophic matrix and midgut epithelium.

Bacteriomes, cryptic forms and evolution of a common wireworm pest species, Hypnoidus bicolor

Insect Molecular Biology, EarlyView.
Wireworms are important agricultural pests, including Hypnoidus bicolor in the Canadian Prairies. Parthenogenetic and sexual populations of H. bicolor appear associated with different molecular clades. Bacterial community composition and structure were influenced by developmental stage, sampling location and host genetics.

Alcoholic extracts of Russian sage (Salvia yangii) contain bioactive terpenoids with inhibitory activity against grapevine downy mildew (Plasmopara viticola)

Pest Management Science, Volume 82, Issue 9, Page 8159-8170, September 2026.
Alcoholic extracts from flowers, leaves, and shoots of Russian sage decreased downy mildew severity on grapevine leaf disks. Fractionation followed by metabolomic analysis revealed putative terpenoids as the main components of the active fractions. Specifically, 7‐methylrosmanol, 12‐O‐methylcarnosic acid, carnosic acid, and carnosol were identified as ...
