Amoeba disease in the queen honeybee National Institute of Agronomic Research
Örösi-Pal, Z..
Queen honeybee have hitherto been found resistant to Malpighamoeba mellificae. For example 516 queens were examined by the author in1954-61, and none was infected. He has now found amoeba cysts in 3 out of 7 dead queens wintered in cages with attendant workers (instead of in a colony). Reasons for this difference between queens free in colonies and caged in incubators are discussed.

Diet effects on honeybee immunocompetence Inra
ALAUX, C.; Ducloz, F.; Crauser, D.; Le Conte, Y..
The maintenance of the immune system can be costly, and a lack of dietary protein can increase the susceptibility of organisms to disease. However, few studies have investigated the relationship between protein nutrition and immunity in insects. Here, we tested in honeybees (Apis mellifera) whether dietary protein quantity (monofloral pollen) and diet diversity (polyfloral pollen) can shape baseline immunocompetence (IC) by measuring parameters of individual immunity (haemocyte concentration, fat body content and phenoloxidase activity) and glucose oxidase (GOX) activity, which enables bees to sterilize colony and brood food, as a parameter of social immunity. Protein feeding modified both individual and social IC but increases in dietary protein quantity...

Distribution of parasitic fungal species richness: influence of climate versus host species diversity Inra
Vacher, C.; Vile, D.; Helion, E.; Piou, D.; Desprez Loustau, M.L..
One major challenge in parasitology and epidemiology is determining whether the richness of parasitic and infectious diseases simply tracks host diversity or is largely determined by exogenous factors, such as climate-forced variables. We addressed this issue by analysing a 30-year survey of fungal diseases in French forests. We first combined generalized linear models and stepwise analyses to select the habitat descriptors that may account for variations in parasitic fungal species richness. Our results suggest that host species diversity is not a major determinant of parasite richness. Temperature seasonality, host abundance, and the composition of host species assemblages may play a greater role. Then we used structural equation modelling to investigate...

Rapid in planta detection of Chalara fraxinea by a real-time PCR assay using a dual-labelled probe Inra
Ioos, R.; Kowalski, T.; Husson, C.; Holdenrieder, O..
Chalara fraxinea is a fungus currently threatening ash trees (Fraxinus excelsior) in several European countries. This emerging pathogen was assigned to the EPPO’s alert list and therefore accurate detection and identification tools are needed. Because of its slow growth rate on agar media and the frequent presence of fast-growing saprotrophic fungi within the host tissue, classical isolation techniques are timeconsuming and sometimes inefficient. In this study, we used species-specific polymorphisms observed within the internal transcribed spacer region to design a primer pair and a dual-labelled probe to be used in a real-time PCR assay for the detection of C. fraxinea. The test proved to be specific, based on in silico and in vitro assessments, and could...

The effect of the intensity of nosema inoculum on queen supersedure in the honey bee, Apis mellifera Linnaeus National Institute of Agronomic Research
Furgala, B..
Queen honey bees (Apis mellifera Linnaeus) were inoculated with known numbers of Nosema apis Zander spores and introduced into frame nuclei. Inoculations with as few as 1000 spores resulted in supersedure. All superseded quees recovered were found infected. The degree of infection, and the time wich elapsed before supersedure resulted, varied within a given dosage level. Some inoculated queens survived and were found free of spores, suggesting that selection for resistance to nosema disease is possible.

The epidemiology and control of nosema disease of the honey-bee National Institute of Agronomic Research
Bailey, L..
The proportion of honey-bees infected with Nosema apis (Zander) declines in summer as the old infected bees die, for they cease to transmit their infection to the newly emerged individuals during the flying season. N. apis spores survive the summer on combs contaminated with infected faeces during the preceding winter. Although bees clean the combs during the summer, all infected material is not removed, and even well-used brood comb, which has been repeatedly cleaned by bees, can carry infection. Only a few bees may contract infection in the autumn from these faeces, but they join the winter cluster and initiate the next outbreak of the disease. Transferring a colony on to clean comb early in the spring or summer removes the source of the disease, and it...

The transmission of nosema disease National Institute of Agronomic Research
Bailey, L..
Results obtained during investigations on Nosema apis at Rothamsted indicated that transmission of the disease from diseased bees to healthy bees virtually ceases during the flying season, and that the primary means of transmission of the disease from year to year is comb which has been soiled by excreta during the winter.

The virulence-transmission trade-off in vector-borne plant viruses: a review of (non-)existing studies Inra
Froissart, R.; Doumayrou, J.; Vuillaume, F.; Alizon, S.; Michalakis, Y..
The adaptive hypothesis invoked to explain why parasites harm their hosts is known as the trade-off hypothesis, which states that increased parasite transmission comes at the cost of shorter infection duration. This correlation arises because both transmission and disease-induced mortality (i.e. virulence) are increasing functions of parasite within-host density. There is, however, a glaring lack of empirical data to support this hypothesis. Here, we review empirical investigations reporting to what extent within-host viral accumulation determines the transmission rate and the virulence of vector-borne plant viruses. Studies suggest that the correlation between within-plant viral accumulation and transmission rate of natural isolates is positive....
