Developmental zero and effective accumulated temperature of larvae of bisexual and parthenogenetic Haemaphysalis longicornis
Objective To determine the developmental zero and accumulated temperature of bisexual and parthenogenetic Haemaphysalis longicornis.Methods The engorged larval ticks of bisexual H.longicornis and parthenogenetic H.longicornis were cultured under different temperatures.The developmental duration and the accumulated temperature were studied.The developmental zero was obtained by using an estimation mode and the effective accumulated temperature was obtained by effective accumulated mode.Results The developmental zero of bisexual and parthenogenetic H.longicornis was 14.89 ℃ and 14.95 ℃,the average accumulated temperatures of bisexual and parthenogenetic H.longicornis were (265.08±99.37)(degree day,DD) and (306.90±176.24) DD respectively,and the effective accumulated temperatures were (101.44±147.66) DD and (116.51 ±116.79) DD respectively.Conclusion The developmental duration of Haemaphysalis longicornis shortened with the temperature increased,and the bisexual H.longicornis developed quicker than the parthenogenetic.The results can be considered as the basic biological parameters of the Haemaphysalislongicornis.
