通过1986~1989年室内外饲养观察,该虫在广州1年发生6代,以雌成虫在被害枝叶上越冬。1月下旬越冬成虫开始产卵。田间若虫于2月上中旬、4月下旬、6月中旬、8月上旬、10月上旬出现5次高峰。该虫的捕食性优势种天敌主要有中华草岭、尼氏钝绥螨。寄生性优势种天敌主要为跳小蜂科的一种小峰(学名待定),对雌成虫的寄生率高达63%~76%。加强观赏植物管理,保护和利用自然天敌,适时施用40%氧乐果、25%喹硫磷、40%速扑杀乳油或60%柴油乳剂,能很好地控制该虫的发生。
Through the observation of indoor and outdoor feeding from 1986 to 1989, the pest occurred in Guangzhou for 6 generations in one year, and the female adult overwintered on the victim foliage. Late-winter adults begin to spawn in late January. Field nymphs in mid-February, late April, mid-June, early August, early October 5 peak. The insects predatory predominant species of natural enemies of Chinese grass Ling, Nius Amblyseius mites. The predominant parasitic dominant species is mainly a small peak of the hopping family Diptera (to be determined), with a parasitic rate of 63% to 76% for female adults. Strengthen the management of ornamental plants, protect and use natural enemies, and timely administration of 40% of omethoate, 25% of quetiapine, 40% cucurbit or 60% diesel emulsion can well control the occurrence of the pest.
