The hepatotoxic alkaloids known to occur in tansy ragwort (Senecio jacobaea L.) are also present in honey produced from the nectar of this species. These alkaloids, which inclued senecionine, seneciphylline, jacoline, jaconine, jacobine, and jacozine, are potentially carcinogenic, mutagenic, and teratogenic and may pose health hazards to the human consumer.
An examination of a commercial honey-bee apiary for theAcarapis species complex revealed the following: queens were essentially free fromAcarapis parasitism colonies were more frequently infested withA. dorsalis andA. woodi thanA. externus; individual worker-bee hosts were rarely parasitized by more than oneAcarapis species. Observed sex ratios, for all(More)
Based on population dynamics, tracheal mite (Acarapis woodi) parasitism of colonies of honey bees (Apis mellifera) appears to be, potentially at least, regulatory and stable. Empirical and theoretical considerations suggest, however, that intracolony population dynamics of mite-honey bee worker seem to be unstable in managed situations where honey bee(More)
The airspace is becoming more and more complicated, and will continue to do so in the future with the integration of Unmanned Aerial Vehicles (UAVs), autonomy, spacecraft, other forms of aviation technology into the airspace. The new technology and complexity increases the importance and difficulty of safety assurance. Additionally, testing new technologies(More)
743 lipid as glycerol and cholesterol esters associated with sugar solutions containing glucose, fructose, and maltose. nic,vicanus were observed in z'izo to contain two clistinct liquid phases (Fig. 1). RESULTS AND DISCUSSION The single phase aqueous layers from both species proved to he typical dilute honey solutions. Silyl ethers of the sugars were(More)
