紫胶虫以吸取优良寄主树上的营养和水分,维持它的生命活动。雄成虫交配后马上死亡,雌成虫泌胶和繁殖后代。该幼虫迁移传播能力很差,只靠涌散期爬行到它所适合的寄主二至三年生枝条上,成群固定下来就不动了。.若让其自然繁殖,紫胶虫本身世代混乱,难于摸索泌胶规律,不好掌握生产程序,同时紫胶幼虫在寄主树上固定过少,不能挖掘寄主树的生产潜力;固虫过多,不仅难以获得高产稳产,而且会导致寄主树整株死亡。人工放养可以创造胶虫所需的环境条件、充分利用紫胶良种、合理利用寄主和适当控制固虫量,实行分片、分株、分枝及分别夏、冬代三年轮流放养(每年利用寄主树上的有效枝条一次),做到永续作业,高产稳产。
Lac bug absorbs nutrients and moisture from the excellent host tree and maintains its life activity. Male males die immediately after mating, and female adults excrete and secrete offspring. The larvae migrate very poorly, and only crawl to the second to third-year-old branches of the host to which it is suitable for the eruptive period. The larvae do not move in fixed groups. If it is allowed to breed naturally, the lacunas themselves are confused from generation to generation, it is difficult to explore the law of secretions and the production procedures are not well controlled. At the same time, lac larvae are too immobilized on the host tree and can not excavate the productive potential of the host tree. , Not only difficult to obtain high and stable yield, but also lead to death of the entire host tree. Artificial stocking can create the necessary environmental conditions for insects and insects, make full use of shelled seed, rational use of host and the appropriate control of the amount of insects, the implementation of fragmentation, ramets, branches and the summer and winter turnaround three years The host tree effective branches once), so that sustainable operation, high and stable yield.
