摘要: 研究了温度、相对湿度和pH对蜜蜂球囊菌(Ascosphaera apis)孢子萌发3个阶段(活化、膨大、产生萌发管)的影响.结果表明,孢子活化和膨大在15~40和(25~40)±05℃范围内受温度的影响不明显(P>005);萌发管仅发生在25~37±05℃,最适温度位于(31~35)±05℃.相对湿度越大,越有利于孢子萌发,而相对湿度低于80%对孢子萌发极为不利.孢子萌发的3个阶段在pH为5~78时几乎不受pH变化的影响,而在pH值较低影响很大.可见,A.apis是一种高度专一的蜜蜂幼虫病原体.

Abstract: Studies on the effects of environmental temperature,relative humidity and pH value on the germination of Ascosphaera apis spore at the stages of activation,enlargement and germ tube production showed that the germination was found to be independent of temperature within the range of 15~40℃ was and 25~40℃,respectively at the stage of activation and enlargement,but closely correlated with the temperature within the range of 25~37℃ at the stage of germ tube production,with the optimum range of 31~35℃.Relative humidity below 80% inhibited spore germination.pH value within the range of 5~7.8 did not affect the spore germination significantly,but pH<5 reduced the enlargement and germ tube production drastically.The results indicated that A.apis is a highly specialized pathogen for the life in honeybee larvae.
