“…Lipid levels are naturally extremely low in adult bees at emergence, even in those which are not parasitised. Czoppelt & Rembold (1970) and Hepburn et al (1979) both found lipid levels to decline by 20-30% during metamorphosis. Therefore, although the mites may have caused a reduction in lipid levels (selective uptake of haemolymph devoid of lipid is untenable), this would be masked by the naturally low levels coupled with the insensitivity of the technique to detect differences at these amounts.…”

Wet weight, dry weight and water contents of emerging honeybees (Apis mellifera L. [Hymenoptera: Apidae]) infested with the ectoparasitic mite Varroa destructor (Anderson) (Acari: Varroidae) were all negatively correlated with increasing numbers of mites. It was estimated that for every female mite present during the bees' development, the host would lose three percent of its body water. Parasitised bees also emerged with lower head and abdomen concentrations of protein and with lower abdominal carbohydrate concentrations. Lipid concentrations were not detectably affected by V. destructor infestation. The losses of metabolic reserves were not, however, judged to be serious enough to be directly responsible for the high bee mortality and ultimate colony collapse that are associated with the arrival of Varroa in a hive. Some 8.5% of the emerging bees exhibited morphological deformities and deformity was positively correlated with increasing numbers of mites in brood cells. Deformed bees were, however, found in all categories of parasitosis, suggesting that other factors, such as infectious agents, may be involved. Mites that fed on either live or dead U14C‐ labelled bees acquired the label within 24 h and it was calculated that an adult female mite consumes 0.67 μl haemolymph 24 h−1. It was also demonstrated that 14C was transmitted to a previously non‐radio‐labelled bee when a mite that had been feeding on a labelled bee changed hosts. The level of transfer was above that which could have arisen through contamination of the mites' mouthparts and supports the suggestion that Varroa is an important vector of pathogens such as viruses.

Thirteen sugars were fed in 0.125, 0.5, and 2 M solutions in water and in 0.5 M sucrose: L‐arabinose, D‐xylose, D‐fructose, D‐glucose, D‐galactose, D‐mannose, lactose, maltose, melibiose, sucrose, trehalose, melezitose, and raffinose. Survival, water consumption, and sugar consumption were measured. No sugar equaled sucrose in acceptance or sustenance. Reduced survival seemed to be associated with aldoses that contain axial hydroxyl groups at C2 or C4 in a C1 pyran ring (mannose, galactose, or arabinose) even if they were in a sucrose solution that ensures feeding. Acceptance was correlated with survival, but whether low acceptance is a consequence or a cause of mortality was not established. When 0.5 M sucrose was supplied separately, bees showed a strong preference for the sucrose solution and were not harmed by small quantities of the other sugars.

Arizona 8571 9 (cooperuting w i t h the University of Arizona) ABSTRACTTwelve sugars in 0.5 fir solution in water and also in 0.5 M solution in 0.5 M sucrose were fed to newly emerged. caged honey bee workcr5. After 11 to 27 hours, the sugars of ice water extracts of degutted tlioraccs were promptly analyzed by thin-layer chromatography.Unlikc published values for sugars in the hemolymph from healthy bees, trehalose was the predominant sugar in the thorax. Lcsser amounts of glucose and only traces of fructose were found. Trisaccharides were found in the thorax after they were fed to bees.Progress was made toward determining which nonsustentative sugars are toxic and which are not accepted. Galactosides seem toxic per se and not to be progenitors of toxic galactose. Galactosides and inannose gave no buildup of a particular sugar to indicate metabolic blockage. Starved bees and moribund bees with empty crops contained glucose but no trehalose. Analysis of thoracic sugars has potential value in diagnosis of bee poisoning.
