Abstract
Experiments were conducted at the apiaries of Nelamangala taluk
of Banglore district. Use of artificially made 9 mm diameter queen cell
cups resulted in maximum acceptance of grafted larvae (66.67 per cent),
emergence of queens (60.42 per cent). Virgin queens were of superior
quality with respect to body weight (134.15 ± 0.07 mg), body length
(14.97 ± 0.01 mm) and other morphometric characters. Cups smeared
with royal jelly showed highest acceptance of grafted larvae (72.50 per
cent), emergence of queens (65.00 per cent) and also, the morphometric
characters of the virgin queens in addition to body weight (133.79 ± 0.20
mg) and body length (14.91 ± 0.03 mm) were found best.
Grafting one day old larva was found ideal as it resulted in higher
acceptance of grafted larvae (71.43 per cent) and emergence of queens
(64.28 per cent) and the quality of the virgin queens with respect to body
weight (134.47 ± 0.26 mg), body length (14.99 ± 0.03 mm) and other
morphometric characters were found superior. Double grafting method of
larva for queen rearing was found the best as it resulted in superior
quality queens with good body weight (143.39 ± 0.47 mg), body length
(15.91 ± 0.08 mm) and other morphometric characters and highest
acceptance of grafted larvae (74.28 per cent) and emergence of queens
(66.43 per cent).
