吐伦球坚蚧Rhodococcus turanicus Archangelskaja是林果业重要害虫之一。2009-2012年,本试验通过田间调查与室内观察相结合的方法对吐伦球坚蚧的生物学特性进行了系统的研究。结果表明:吐伦球坚蚧在新疆轮台县1年发生1代,以2龄若虫群集固着于杏树1年~6年生枝条上越冬,该害虫的发育与杏树物候及当地气温关系密切。吐伦球坚蚧在田间的消长以若虫发生量最大,时期最长。单雌最大产卵量为3500粒,体重与产卵量的预测模型为:^Y=80790 X2+11.874。卵的发育起点温度(C)9.15±0.1593℃;有效积温(K)290.17±4.876DD。若虫的平均孵化率为91.3%,初孵若虫可向光源爬行至3~4 m,主要选择在叶片背面固定取食,杏树落叶期若虫由叶片向枝条转移,多选择在3年~4年生枝条背面越冬。成虫雌雄性比约为1∶2,营两性生殖。
Tuodosporium Rhodococcus turanicus Archangelskaja is one of the major pests in the fruit industry. From 2009 to 2012, we conducted a systematic study of the biological characteristics of Chironidae from the field investigation and indoor observation. The results showed that Tuodosporidium kuehne had one generation per year in Luntai County of Xinjiang Autonomous Region. The 2nd instar nymphs were colonized by 1-year-old 6-year-old branches of apricot trees. The development of pests was closely related to the phenology of apricot and local temperature . Tuoling ball scale insects in the field of growth and decline to the largest number of nymphs, the longest period. The maximum fecundity of a single female was 3500 grains, and the prediction model of body weight and fecundity was: Y = 80790 X2 + 11.874. Egg development starting temperature (C) 9.15 ± 0.1593 ℃; effective accumulated temperature (K) 290.17 ± 4.876DD. Nymphs average hatching rate of 91.3%, the first nymphs can crawl to the light source to 3 ~ 4 m, the main choice of fixed feeding on the back of the leaves, apricot deciduous nymphs from the leaves to the branches, and more choice in 3 years to 4 years The back of the branches wintering. Adult male and female ratio of about 1: 2, Camp amphibious.
