陕北东亚钳蝎体重和性别与产毒量的相关性

Correlation Between Body Weight, Gender and Venom Yield of Wild Scorpion Buthus martensi Karsch in Northern Shaanxi

为探明陕北东亚钳蝎体重和性别与产毒量的相关性,本实验采用电刺激法提取陕北野生东亚钳蝎毒液,比较了蝎子体重和性别与产毒量的关系。结果表明,蝎产毒量与体重呈正相关,体重越大的蝎子,其产毒量也越多。300~1400 mg的雌蝎,产毒量为(5.72±1.64)^(16.68±3.55)mm;300~900 mg的雄蝎,产毒量为(5.68±1.54)^(16.17±3.36)mm。500~900 mg的同体重雌雄蝎,雄蝎产毒量明显高于雌蝎,暗示雄蝎与雌蝎在运动、采食量等方面存在较大差异。该研究结果为陕北野生蝎蝎毒的功能研究奠定了一定的实验基础。

In order to investigate the correlation between body weight, gender and venom yield of wild scorpion Buthus martensi Karsch in Northern Shaanxi, venom yield of scorpion was analyzed. Electrical stimulationmethod was adopted to extract scorpion venom. The results showed that venom yield ranged from（5.72±1.64） to（16.68±3.55） mm in the female scorpion（300~1400 mg）, and from（5.68±1.54） to（16.17±3.36） mm in the malescorpion（300~900 mg）. Thus it indicated that scorpion body weight had a significantly positive correlation withvenom yield. Moreover, venom yield of male scorpions（500~900 mg） was much more than that of female ones,which indicated that scorpion had gender differences in mobility and food consumption. These results may laya foundation for developing rich wild scorpion resources in Northern Shaanxi.
