Honeybee populations have locally and temporally declined in the last few years because of both biotic and abiotic factors. Among the latter, one of the most important reasons is infection by the microsporidia , which is the etiological agent of type C nosemosis. This species was first described in Asian honeybees (). Nowadays, domestic honeybees () worldwide are also becoming infected due to globalization. Type C nosemosis can be asymptomatic or can cause important damage to bees, such as changes in temporal polyethism, energy and oxidative stress, immunity loss, and decreased average life expectancy. It causes drastic reductions in workers, numbers of broods, and honey production, finally leading to colony loss. Common treatment is based on fumagillin, an antibiotic with side effects and relatively poor efficiency, which is banned in the European Union. Natural products, probiotics, food supplements, nutraceuticals, and other veterinary drugs are currently under study and might represent alternative treatments. Prophylaxis and management of affected colonies are essential to control the disease. While is one potential cause of bee losses in a colony, other factors must also be considered, especially synergies between microsporidia and the use of insecticides.

A cross-sectional study design was conducted in different agroecological zones of southwest Ethiopia from October 2019 to October 2021. The study aimed to determine the prevalence and associated risk factors for honeybee diseases and pests, as well as the impact of these issues on honeybee colonies and their products. To identify potential risk factors for honeybee disease and pests, a multivariate random effects logistic regression analysis was used.

Declines in honeybee abundance have been observed worldwide during last decades. This is partly due to plant protection agents used in intensive farming, landscaping and infrastructure maintenance. Another type of factors negatively affecting honeybees is the spread of diseases caused by different pathogens and pests.

Nosemosis type C is a dangerous and widespread disease of the adult European honey bee and is caused by the spore-forming intracellular parasite . The search for new ways of therapy for this disease is complicated due to the seasonal availability of -infected insects as well as the lack of a developed system for the pathogen's cultivation. By carrying out trials which used different infectious dosages of the parasite, spore storage protocols, host age, and incubation temperatures, we present a simple, safe, and efficient method of propagation in artificially infected worker bees in the laboratory.
