白蜡虫泌蜡研究 Ⅱ.不同寄主植物上的泌蜡比较

Studies on Secreting Wax of Chinese White Wax ScaleⅡ. The Comparison of Secreting Wax on Different Host Plants

本文报道了在昆明地区女贞、白蜡树和小叶女贞三种不同寄主植物上白蜡虫的泌蜡状况。试验结果表明，通过在三种寄主树上放养昆明种虫和昭通种虫，不同寄主的雄虫个体平均泌蜡量，单头种虫产蜡量因种虫和寄主不同而不同；白蜡虫在不同寄主上泌蜡存在高峰期，泌蜡高峰期因寄主和种虫不同而异；白蜡虫历时基本上不受寄主的影响，在３种寄主上大致相同。用白蜡虫雄虫个体平均泌蜡量、单头种虫产蜡量和泌蜡历时等指标衡量，在昆明地区，女贞是白蜡虫的优良寄主。

Chinese white wax scale have different adaptability to different host plants,and the state of secreting wax are not the same.It is reported in this paper that the secreting wax state of the insect on hosts of Ligustrum lucidum,Fraxinus chinensis and Ligustrum quiboni in Kunming area.The research results have shown that the average secreting wax amount of each male insect and each female scale and the secreting wax peaks are not the same depending on different female scales and hosts.The secreting wax period of the insect is not affected by the hosts on the whole.A comprehensive judging from the average secreting wax amount of each male insect and each female scale and the secreting wax period,L.lucidum is the best host of Ericerus pela in Kunming area.
