白蜡虫泌蜡研究 Ⅰ.不同地理种源泌蜡比较

Studies on Wax Secretion of Chinese White Wax Scale ( Ericerus pela Chavannes) Ⅰ:The Comparison on Wax Secretion of Different Geographic Varieties

本文对云南昆明、昭通和四川金口河三个不同地理种源白蜡虫的泌蜡状况进行了研究。结果表明，昆明虫泌蜡历时最长，泌蜡量最高，昭通虫泌蜡历时和泌蜡量次之，金口河虫泌蜡历时短，泌蜡量低。在泌蜡周期中，白蜡虫泌蜡有高峰期，昆明虫泌蜡高峰期在泌蜡后５０ｄ，昭通虫在泌蜡后３０ｄ，金口河虫在泌蜡后２０ｄ。酯酶同工酶和过氧化物酶同工酶测定结果表明，三个不同地理种源的白蜡虫种群已产生了分化，昆明种虫与昭通种虫分化较小，昆明种虫和昭通种虫与金口河种虫的分化较大。

It is reported in this paper that the wax secretion state of three geographic varieties of Chinese white wax scale. The research results have shown that Kunming variation has the longest wax secretion period and the largest wax secretion amount,Zhaotong variation has shorter period and less amount than Kunming variation,Jinkouhe variation has the shortest wax secretion period and the least wax secretion amount among the three varieties. There is a wax secretion peak in whole wax secretion period. Kunming variation peaks on the 50th day after the beginning of wax secretion, Zhaotong variation peaks on the 30th day,Jinkouhe variation peaks on the 20th day. The experimental results of esterase and peroxidase isozymes have demonstrated that there are some degree of differentiation among the three geographic varieties. There is small differentiation between Kunming and Zhaotong variations,but they differ obviously from Jinkouhe variation.
