摘要
柿广翅蜡蝉为杂食性害虫,可危害多种农林作物。该虫以产卵刻痕的危害方式对茶树造成危害,为了解其在茶树上的产卵习性,采用室内饲养和茶园实地调查的方法,研究了柿广翅蜡蝉的发生与产卵特性。结果表明：柿广翅蜡蝉在苏州地区茶树上1年只发生1代,10月初开始产卵,中下旬是产卵高峰期,持续至12月底。成虫喜产卵于直径为0.3 cm左右2年生枝条表皮光滑处,刻痕长度0.5-2.5 cm,每刻痕内有卵粒6-38粒。卵孵时刻痕表面的白色蜡丝逐渐消失,呈现出灰褐色。该结果可为苏州地区茶树上蜡蝉的发生规律及防治时间提供参考。
Ricania sublimbata Gacodi belongs to omnivorous pest and harms a variety of crops, their oyiposition and niduses harm to tea. To understand its spawning habit on tea, we carried out field investigation and laboratory feeding to study its occurrence and ovipositing characters. The results showed that R. sublimbata Gacodi only possessed one generation during one year on tea in Suzhou. Their oviposition started in early October, ended at the end of December, and the peak was from llth to 30th October. The adults deposited eggs on the smooth epidermis of 2 years old branches which diameter was about 0.3 cm. The length of nidus was 0.5-2.5 cm, and each nidus existeded 6-38 grains of eggs. The white wax filaments on the surface of nidus disappeared gradually and turned to gray-brown when the eggs hatched. These results provide the gui- dance for reseaching on occurrence regularity and control time of Ricania sublimbata Gacodi on tea in Suzhou.
