柑桔绵蚧[Chloropulvinaria aurantii(Ckll.)]是柑桔园昆虫相中的一个种,经常处在自然控制之下,在历史上从未有造成为害。但自五十年代末,由于有机磷农药的大量使用,破坏了生态平衡,在不少地区,如浙江黄岩、温州、衢县和江苏吴县均有为害的报导。此后时起时伏,一直延续至八十年代,对柑桔生产常构成威胁。检索过去有关文献,仅有简短叙述,作者通过观察与实践,澄清了一些问题。现作一简报。 发生规律 一、柑桔绵蚧的生活史 柑桔绵蚧在浙江黄岩一年发生一代,以2龄若虫在枝叶上越冬。雄虫于3月下旬至4月下旬化蛹,4月中旬为化蛹盛期。4月 Chloropulvinaria aurantii (Ckll.) Is a species found in citrus orchards and is often under natural control and has never been harmed in history.

Since then, the volt has been extended to the eighties, often posing a threat to citrus production. Retrieve the past literature, only a brief description, the author through the observation and practice, to clarify some of the issues. Let me give you a briefing now.
