Abstract
Changes in dimensions of artificial queen cups containing transplanted worker honeybee larvae (Apis mellifera) were followed statistically as the cups were drawn by nurse bees for 7-26 h, and percentage acceptance of larvae was correlated 'vith cup size (6 rnrn or 12 rnrn) and form ('undrawn' or 'drawn'). Dimensions of empty 6-mm cups of 5'97 ± 0'029 mm internal length, 8'07 ± 0'025 mm opening diameter and 3'00 ± 0'018 rnrn maximum base-wall thickness were altered by queenless workers over a 24-h period to 3'71 ± 0'025 rnrn length, 5'47 ± 0'055 rnrn opening diameter, and 5'75 ± 0'054 rnrn base-wall thickness. Empty 12-mm cups of 11'97 ± 0'029 mm length, 8'87 ± 0'027 rnrn opening diameter and 3'10 ± 0'031 mm base-wall thickness were similarly modified to produce corresponding dimensions of 8'89 ± 0'033 mm, 5'34 ± 0'057 rnrn and 5'28 ± 0'059 mm. Percentage acceptance of transplanted worker larvae 24 h old for 4 types of cups was: 6-mm undrawn, 10'9%; 6-rnrn drawn, 48'6%; 12-mm undrawn, 63'9%; 12-rnrn drawn, 78'6%. Percentage acceptance for larvae transplanted into 12-mm cells drawn for different periods was: 7 h, 50%; 14 h, 70%; 21 h, 75%; 26 h, 87'5%. It was concluded that the drawing procedure significantly improved the acceptability of artificial cups, and that any special property acquired from the cups being drawn was less effective in  promoting acceptance than an increase in cell length of 8 rnrn but more effective than an increase of 3 rnrn.
