西方蜜蜂产浆适龄幼虫及取浆时间

The Instar Best for Royal Jelly Production and the Time of Collecting Royal Jelly of

对西方（ＡｐｉｓｍｅｌｉｆｅｒａＬ．）采用１和２日龄工蜂幼虫产浆的王台接受率和不同时间取浆浆量进行研究，结果显示：（１）２日龄工蜂幼虫的王台接受率（８０．６７％）极显著高于１日龄（４９．３３％）（Ｐ＜０．０１）；（２）１和２日龄幼虫产浆的台平均产浆量最高峰分别在各自移虫后第８４ｈ和第７２ｈ，浆量较高时段分别在移虫后第７８—９０ｈ和第６８—７８ｈ．２个日龄幼虫产浆最高浆量之间及浆量较高时段的浆量均无显著差异，但采用２日龄幼虫产浆的比１日龄幼虫的提前１２ｈ达到台平均产浆量高峰和浆量较高时段．（３）采用２日龄幼虫产浆其总产浆量可比采用１日龄的增加５６％．通过试验认为，西方蜜蜂产浆采用２日龄幼虫。

This paper deals with the rate of cell reception and the average yield of royal jelly per cell in the different time after transfering with 1 day old instars and with 2 days old instars for royal jelly production of Apis mellifera. The results are as follows:(1)The rate of cell reception with 2 days old instars (80.67%) is remarkable highter than that with 1 dqy old instars(49.33%)(P<0.01);(2)The time when the average yield of royal jelly per cell with 2 days old instars reaches the highest peak is 12 hours earlier than that with 1 days old instars;(3)The total yield of royal jelly with 2 days old instars is 56% higher than that with 1 day old instars. According to the test, we suggested that the 2 days old instars and collecting royal jelly at between the 66th and 78th hour after transfering could be best for royal jelly production of A. mellifera.
