Artificial Bee Beds for the Propagation of the Alkali Bee, Nomia melander
- W. Stephen
- 1 December 1960
The construction of artificial beds for the propagation of the alkali bee ( Nomia melanderi Ckll.) was achieved by duplicating the texture, moisture, and alkalinity of the native soils in which the… Expand
Time related decay in prey antigens ingested by the predator Podisus maculiventris (Hemiptera, Pentatomidae) as detected by ELISA
SummaryIndividual nymphs of the predaceous pentatomid Podisus maculiventris Say were each fed a single first instar Douglas Fir tussock moth larva, Orgyia pseudotsugata McDunnough, and held without… Expand
Effect of temperature on development and survival in post-diapausing alfalfa leafcutting bee prepupae and pupae (Megachile rotundata (F.): Hymenoptera: Megachilidae). I. High temperatures.
Pupae and prepupae of developing leafcutting bees, Megachile rotundata (F.) were exposed to 45? and 50?C for periods of 15 minutes to 3 hours. The 50?C treatments caused total mor tality regardless… Expand
Biological notes on the leaf-cutter bee, Megachile (Eutricharaea) rotundata (Fabricius)
The Effect of Sublethal Doses of Parathion on Honeybee Behaviour. I. Oral Administration and the Communication Dance
SummaryThe oral sublethal dose of parathion in honeybees was determined as less than 0–03 μg per bee. Sublethal doses of parathion prevented bees from communicating the direction of a food source to… Expand
Effects of Bee Species and Isolation Distance on Possible Varietal Contamination in Alf 1
The Effect of Sublethal Doses of Parathion. II. Site of Parathion Activity, and Signal Integration
SummaryComparison of dance angles of parathion-treated bees on vertical and on horizontal comb revealed that poison-induced deviations were minimal or absent on the horizontal plane. Marked… Expand
Effect of temperature on development and survival in post-diapausing leafcutting bee pupae (Megachile rotundata (F.)). II. Low temperature.
At the time of the first male emergence leafcutting bee cells were exposed to temperatures of 4.4?, 15.6?, 18.3?, 21.1? and 23.9?C for one to 16 consecutive days; to a diurnal cycle of 15.6? and… Expand
