Summary — One-hundred and forty-eight molds were isolated from the following samples of almond, Prunus dulcis, pollen : floral pollen collected by hand; corbicular pollen from pollen traps placed on colonies of honey bees, Apis mellifera, in the almond orchard; and bee bread stored in comb cells for one, three, and six weeks. The majority of molds identified were Penicillia (32%), Mucorales (21%), and Aspergilli (17%). In general, the number of isolates decreased in pollen as it was collected and stored by the bees. Each type of pollen sample appeared to differ in regard to mold flora and dominant species. Aureobasidium

“…Generally, yeast number was raised after exposure of honeybees to stressful factors: even keeping honeybees in cages, without a bee queen or the possibility of flying, increased the number of yeast CFUs (18)(19)(20)(21)(22). Therefore, data which indicated decrease in yeast CFUs number after feeding honeybees with commercial probiotics could be misunderstood as beneficial; but when comparing these data with the nosemosis development (Fig.…”

“…Some intestinal yeasts common among higher animals have a trophic effect because of providing a source of B vitamins, proteins, trace minerals and essential amino acids, and therefore can be treated as probiotic microorganisms for mammals. But healthy free flying honeybees have only few yeasts if any; moreover some studies suggest that yeast can be considered as honeybees' stress indicators (7,(16)(17)(18)(19)(20)(21)(22). Furthermore, the addition of yeast to honeybees' diet leads to damage of the midgut epithelial layer (28).…”

The natural intestine microbiota of honeybees is dominated by Gram-negative bacteria from such families as: Enterobacteriaceae, Alcaligenaceae and Pseudomonadaceae, less numerous are Gram-positive bacteria, yeasts and other fungi. Our research was focused on the impact of commercial vertebrae probiotics, on honeybees’ intestine yeast number, hemolymph lysozyme activity and nosemosis development. The diet of honeybees was supplemented with two vertebrate probiotics recommended in beekeeping management. The former consisted of Lactobacillus casei, L. plantarum, Saccharomyces cerevisiae, and Rhodopseudomonas palustris. The latter consisted of L. acidophilus, L. delbrueckii, and Bifidobacterium bifidum. Yeasts isolated from honeybees’ intestine and detected in our research belonged to two genera: Candida and Saccharomyces. The average number of yeast Colony Forming Units (CFUs) in uninfected honeybees fed only sugar syrup was 3850 (±400.33) and after Nosema spp. infection the number rose to 19500 (±1644.40) per one honeybee. The addition of a probiotic decreased the number of detected yeast CFUs in both groups of infected and uninfected honeybees. Nosema infection did not affect lysozyme activity; therefore it was the administration of probiotics that had the main impact on the rise of lysozyme level. Most likely very vivid probiotic bacteria were treated as invaders by honeybees’ immune defense, which resulted in almost 40% rise observed in lysozyme activity. Furthermore, probiotic supplementation accelerated the nosemosis development even twofold. Probably, increased acidity of the honeybees’ intestine, which is a consequence of the uncontrolled growth of lactic acid bacteria, created conditions favorable to faster nosemosis development. Therefore, every administration of diet supplements with live microorganisms whose impact on honeybees biology and physiology is not well studied should be carried out with the greatest caution.

“…The association with a microbial flora in the digestive tracts of several insect groups, such as Lepidoptera, Coleoptera, Isoptera, among others, is widely exemplified by studies of insect-fungus interactions (15,16,17,36). Furthermore, a wide variety of bloodsucking arthropods, among these the triatomines (11,28), have been reported to contain symbiotic microorganisms.…”

This paper reports a study on the mycobiota in the digestive tract of four important species of triatomines: Rhodnius prolixus, R. neglectus, Diptelanogaster maximus and Panstrongylus megistus. The digestive tracts of 90 adults and 425 nymphs of these four triatomine species were studied and 365 fungal strains were isolated. The genera with the greatest number of species were Aspergillus, Penicillium (14 species in each genus), Acremonium and Cladosporium (three species in each genus), and the most frequent species, in decreasing order, were Aspergillus awamori, Penicillium corylophilum, Cladosporium herbarum and Aspergillus niger. It was concluded that, among the isolated fungi, Aspergillus niger and Penicillium corylophilum might be part of the natural flora of the digestive tract of triatomines.
