“…The total number of haemocytes increased, as did the proportion of older haemocytes which may be nutrient cells, while there were fewer young haemocytes as described by other authors as plasmatocytes or prohaemocytes (Wienands et al, 1987;Wienands and Madel, 1988;van Steenkiste, 1988;Papadopoulou-Karabela et al, 1993). Our results are in agreement with those of previous studies that found that plasmatocytes are the most numerous cells in haemolymph of young honeybee from free-flying colonies (Jędruszuk, 1998a(Jędruszuk, ,1998b(Jędruszuk, , 1998c.…”

-The influence of different diets on the haemolymph of adult honeybee workers was examined. The laboratory experiments took place in early summer. There were three experimental groups fed with one of the following diets: pollen with sugar, pollen substitute alone, or sugar. A sample of haemolymph was taken from 7-8 day old bees and numbers of haemocytes of each type (plasmatocytes, granular haemocytes, and other types of haemocytes pooled together) were recorded and the metabolic activity of haemocytes was observed. A lack of protein caused a significant increase in the percentage of granular haemocytes, a significant decrease of other types and a lower metabolic activity. The examined pollen substitute caused a decrease of total haemocyte count. The decrease in the metabolic activity of haemocytes was lower than without protein.Apis mellifera / diet / haemocyte / adult worker

“…Generally, it could be concluded that during the first period of the one hour of the microbial injection an elongation and minor abnormalities were occurred in some Paenibacillus larvae spore's effects on the blood cells of immature and mature honey bee workers were detected by Zakaria (2007). Papadopoulou et al, (2003) reported that blood cells of the honey bees artificially infected with Pseudomonas aeruginosa cause septicemia showed not significantly effect on the total and differential haemocyte counts. Also, deficient nutrition can impair immune function and increase the susceptibility of individuals to disease as suggested by Alaux et al,…”

his work aimed to study the pathogenic effect of the Paenibacillus larvae spores on adult honey bee workers to explain the death many of them in the communities affected by American foul brood disease. This work was done through two methods; first injected the microbial suspension in the intersegmental membrane of the back lymph cavity of adult bee workers. The blood films were done after 1, 2, 4&12 hrs. beginning of the injection method, while with the feeding method it carried out after one, two and three months. During the first period of the microbial injection one hour later an elongation and minor abnormalities were occurred in some blood cells. The second stage began after 2 hrs. is characterized by loss of the blood cells dye strength. After 4 hrs. the third stage is characterized by increase atrophies of some blood cells. The fourth and final stage after 24 hrs. abnormalities in most blood cells with sharp decline in their numbers clearly. This stage considers beginning end of the blood cells alive and the rapid death of most of bee workers was detected. This experiment affirms that adult bee workers can be affected by the Paenibacillus larvae spores. That may be one reason of death bee workers in infected bee colonies by the American foul brood disease.
