Regulation of hemolymph osmolality in feral and domestic honeybees, Apis mellifera L. (Hymenoptera: Apidae)

Autor: Allen Carson Cohen, Anita H. Atmowidjojo, Diana E. Wheeler, Eric H. Erickson

Publikováno v: Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology. 122:227-233

Experiments were conducted to compare the ability of unmanaged feral and managed domestic honeybees in the arid Southwest to regulate hemolymph solutes, osmolality, and uric acid. Honeybees from feral and domestic colonies were desiccated (at 30°C a

Territoriality and the Africanized honey bee

Autor: Eric H. Erickson

Publikováno v: Bee World. 80:119-123

Unlike domesticated European honey bees, Africanized honey bee (AHB) colonies can be extremely defensive. Extremely defensive colonies appear to practice territorial defence wherein members of the colony aggressively patrol and defend territories tha

A comparison of two assays to test the defensive behaviour of honey bees ((Apis mellifera)

Autor: Robert E. Page, Ernesto Guzman-Novoa, Hayward G. Spangler, Eric H. Erickson

Publikováno v: Journal of Apicultural Research. 38:205-209

SUMMARYThe reliability of a traditional leather-patch assay to measure the stinging behaviour of honey bees was compared with that of a temper detection apparatus developed to electronically measure and record defensiveness. Colonies were tested with

Temperature tolerance and water balance in feral and domestic honey bees, Apis mellifera L

Autor: Anita H. Atmowidjojo, Eric H. Erickson, Allen C. Cohen, Diana E. Wheeler

Publikováno v: Comparative Biochemistry and Physiology Part A: Physiology. 118:1399-1403

Feral and domestic honey bees were compared to determine relative levels of adaptation to the Arizona desert. Feral honey bees were more tolerant to high temperatures than domestic honey bees. Monthly critical thermal maxima (CTMs) of feral bees were

Tyrosine Nodules in the Gasters of Adult Honeybees

Autor: Eric H. Erickson, William Lusby, Brett Cameron, Donald L. Brummett, Allen C. Cohen

Publikováno v: Journal of Invertebrate Pathology. 70:27-32

Opaque white nodules were discovered in the gasters of worker honeybees taken from hives infested with Varroa jacobsoni and stored in alcohol for 3 to 5 days. Dissection revealed that these nodules are most often attached to the inner cuticle or midg

Effects of selected insecticide formulations, phased application and colony management strategies on honey bee mortality in processing sweetcorn

Autor: J L Wedberg, P K Flottum, J A Wyman, Eric H. Erickson, Robert E. Page, B H Erickson

Publikováno v: Journal of Apicultural Research. 36:3-13

SUMMARYThese studies were undertaken to evaluate different strategies for reducing losses of honey bees (Apis mellifera) due to the use of insecticides in commercial sweetcorn (Zea mays) production fields. The strategies were: (1), insecticide applic

BEEAMATE: A honeybee colony genetics models

Autor: Gloria DeGrandi-Hoffman, Stephan A. Roth, Gerald M. Loper, Eric H. Erickson

Publikováno v: Ecological Modelling. 51:299-314

BEEAMATE is a computer model that simulates the genetic composition of a honeybee (Apis mellifera L.) colony, and determines the number of individuals carrying particular combinations of alleles at any time (t). Determination of a colony's genetic co

Extractable hydrocarbons and kin recognition in honeybee (Apis mellifera L.)

Autor: R. A. Metcalf, Richard L. Lampman, Robert E. Page, Robert L. Metcalf, Eric H. Erickson

Publikováno v: Journal of chemical ecology. 17(4)

Hydrocarbons of worker honeybees of known pedigree were extracted and analyzed using gas chromatography and mass spectrometry. Variability in hydrocarbon extracts of individual workers is determined at least in part genetically. Correlations in hydro
