目的研究长角血蜱两性生殖株和孤雌生殖株幼蜱在不同温度下的发育零点和有效积温。方法将长角血蜱两性生殖株和孤雌生殖株饱血幼蜱置于不同温度的环境中,观察发育历期和积温,采用拟合模型方程求出两性株和孤雌株幼蜱发育的零点温度,计算幼蜱发育的有效积温。结果长角血蜱两性株和孤雌株的发育零点分别为14.89℃和14.95℃,平均积温分别为(265.08±99.37)日度和(306.90±176.24)日度,有效积温分别为(101.44±147.66)日度和(116.51±116.79)日度。结论长角血蜱饱血幼蜱的发育历期随温度升高而缩短,两性株比孤雌株发育快,研究结果可以作为长角血蜱生物学的基础理论参数之一。
Objective To study the developmental zero point and effective accumulated temperature of Larvae of Sexual Hormones and Parthenogenetic young ticks at different temperatures. Methods The larvae of T. sexurian and parthenogenetic full-larvae were placed in different temperature environments. The developmental duration and accumulated temperature were observed. The fit model equations were used to determine the development of juvenile ticks Zero temperature, calculate the effective cumulative temperature of young tick development. Results The developmental loci of L. sexta and L. gondii were 14.89 ℃ and 14.95 ℃, respectively. The average accumulated temperatures were (265.08 ± 99.37) days and (306.90 ± 176.24) days, respectively. The effective accumulated temperatures were (101.44 ± 147.66 ) Daily and (116.51 ± 116.79) days. Conclusion The developmental duration of T. chrysogenum short-blooded ticks is shortened with the increase of temperature, and the development of male and female strains is faster than that of parthenogenetic plants. Therefore, the results of this study can be used as one of the basic theoretical parameters in the biology of C. longicornis.
