不同採蜜法對蜜蜂白堊病發病及蜂蜜產量之影響

THE EFFECT OF HONEY HARVESTING METHODS TO THE OUTBREAK OF CHALKBROOD AND YIELD OF HONEY

摘要


1986年流蜜期以換王、關王、一般採蜜、及不採蜜等不同方式處理蜂羣。結果發現流蜜期無幼蟲罹病、流蜜期結束後,一般採蜜處理者,其白堊病發病率明顯高於換王與關王處理者及對照組。且換王與關王處理者,產蜜量較一般採蜜為高。一般採蜜法不限制蜂王產卵,以致流蜜期結束後,幼蟲數遠高於前二處理者。故產蜜量減少可能因幼蟲數多,消耗蜂蜜量亦多所致。流蜜期結束,白堊病爆發,其原因可能與一般處理組有大量幼蟲,外界環境食物不足,造成幼蟲營養壓力有關。

Bee colonies were treated with four treatments, i. e. queen-removed, queen-caged, general harvest and without harvest, during the nectar flow period in 1986. The results showed that the chalkbrood were more serious and honey production were less in general harvest colonies. Queens were not restricted from laying eggs during the nectar flow, so the number of larvae were much more in general harvest colonies than queen-removed and queen-caged treatments at the end of the period. According to the results obtained the infection rates of chalkbrood in bee colonies are related to the supply of food.
