北方茶园绿盲蝽年种群动态规律研究

Study on the Annual Population Dynamics of Apolygus lucorum in the Tea Plantation in Northern China

针对绿盲蝽严重为害北方茶园的问题,通过目测法、性诱法、剥查法,研究确定绿盲蝽在茶园的年种群动态及越冬产卵规律。结果表明:绿盲蝽成虫在茶园每年发生5代,从第三代出现世代重叠;九月下旬到十月上旬,以第四代成虫为主体的绿盲蝽大量回迁茶园。绿盲蝽若虫数量在茶园每年有春季和秋季2个高峰。绿盲蝽越冬卵主要散产于茶树枝条当年剪口的髓部海绵状组织内,卵数占总量的70.74%,其次为茶树花托上,卵数占总量的20.63%。生产上,可以于9月下旬到10月上旬,在茶园采用化学药物驱避或物理阻隔,阻止绿盲蝽成虫回迁茶园,以减少越冬卵数量。

Focusing on the serious damage of Apolygus lucorum on the tea plantation in Northern China,the annual population dynamics of A. lucorum was investigated by visualizing, sexual trap and bark stripping methods. The results showed that A. lucorum occurred five generations in the whole year in tea plantation. Generation overlapping appeared from the third generation. The adult of A. lucorum returned to the tea plantation from the late September to early October, in which the fourth generation of adults was the main group. The number of nymphs of A. lucorum had two peaks each year in spring and autumn. The overwintering eggs of A. lucorum mainly scattered in the spongy tissue of the pith of the tea branch with a proportion of 70.74% of the total number, followed by the tea tree receptacles with a proportion of 20.63%. We can be in late September to early October, the usage of chemical drugs in the tea garden ward off or physical barrier, prevent blind green bugs adult returned tea garden, to reduce the number of overwintering eggs.
