摘要:

SummarySignificant variation with locality was observed in 18 characters of the fore- and hind wings of worker honeybees (Apis cerana indica) collected from the Himachal region, and in 14 characters of bees from the Kashmir region, in north-west India. A number of wing measurements were positively correlated with altitude. For Himachali bees these included length and breadth of both fore- and hind wings, proportions of several wing-vein cells, size of some cell angles, and number of hamuli. For Kashmir bees they included breadth of fore-wing, proportions of some wing-vein cells, size of some cell angles, and number of hamuli. Most wing parameters were significantly larger in the Kashmiri bees, but not number of hamuli, length of the apical portion of the radial vein, or certain wing-vein angles.

摘要:

SummarySeasonal honey production, worker pupal weight, length of worker adult life, and dimensions of worker corbiculae were determined for 19 colonies of honeybees (Apis mellifera) at one apiary. Honey production was correlated significantly with length (r= +0·551, P<0·0145) and area (r= +0·575, P<0·01) of corbicula. Area of corbicula was correlated significantly with length of life (r= +0·687, P<0·0012). Selection of honeybees for large corbicular area might increase honey production by permitting more pollen to be brought to the colony and consequently increasing the brood area and/or the length of life of the workers raised. Corbicular area was an important component of colony honey production throughout the year, and especially in weeks of good average colony weight gain.

摘要:

SummaryA sample of 90 haploid and 80 diploid males ofMelipona quadrifasciatawas studied for sexual maturity. Haploid males were found to have an average of 1 044 000±41 500 spermatozoa and diploid males an average of 546 500±23 200. Migration of spermatozoa from the testes to the seminal vesicles began on the seventh day in haploid males and on the ninth day in diploids.

摘要:

SummaryA simple aerial trap for collecting drones in congregation areas is described. Large numbers (>1000) of drones can be collected on days favourable for drone flight. When used with a population containing marked drones the trap permits the assessment of age, race and apiary of origin of the drones in the congregation area. This trap has several advantages over previous sampling methods.

摘要:

SummaryA plastic queen holder which can be used to obtain matings by drones in congregation areas is described. Copulating drones become stuck in the tube, and can be recovered and examined. When the device is used with a population containing marked drones, their age, race and apiary of origin can be determined.

摘要:

SummaryWorker honeybees (Apis mellifera) recovering from CO2narcotization emitted a distinctive‘quacking’sound consisting of a series of short notes, each possessing multiple harmonics and a fundamental frequency around 400 Hz. Quacking was usually accompanied by a distinctive‘shoving’behaviour. Paired bees‘quacked’more frequently than single bees. The similarity of worker quacking to certain variants of queen piping and worker piping is discussed.

摘要:

SummarySister queen honeybees (Apis mellifera), 59 instrumentally inseminated (IIS) and 59 naturally mated (NM), were produced in Baton Rouge, Louisiana, and put into field colonies at 3 locations in Alberta, Canada and at 1 location in Louisiana, USA. Survival of the IIS queens was lower than that of the NM queens; 37 IIS queens and 50 NM queens survived from August 1981 to May 1982, and 18 IIS and 34 NM queens survived until August 1982 (P<0·01). At all 4 locations, the colonies with NM queens had 21–73% more capped brood in May (February in Louisiana) than did colonies with IIS queens (P<0·01). Probably because of this difference in brood production, the colonies with NM queens produced more honey. Over a 12-month period, the mean loss of spermatozoa from IIS queens was 0·9 million (28% of the original number in the spermatheca), and the mean loss for NM queens was 1·5 million (27%).

摘要:

SummaryAryl hydrocarbon hydroxylase and glutathione S-transferase activity was determined in post-mitochondrial fractions of the miteVarroa jacobsoni(Oudemans) and the honeybee (Apis mellifera). Aryl hydrocarbon hydroxylase activity in the mite was about a third of that found in the honeybee, whereas the glutathione S-transferase activity was similar in the two. The results obtained may be relevant to the screening of acaricides to control the mite.

摘要:

SummaryCounts of sperm and tests for nosema disease were done in queen honeybees (Apis mellifera) over a 6-year period on their arrival in western Canada from the United States. During that period,Nosemawas found in 0·5–18% of the queens (mean 7·5%); 11% of the queens had fewer than 3 million sperm. In each year a high percentage (i.e., 45–64%) of the queens had over 5 million sperms. Sperm counts and nosema disease in queens were also examined in relation to the State of origin in USA and their date of arrival in Canada.
