休眠卵萌发实验表明 ,影响蒙古裸腹氵蚤休眠卵萌发的因子有暗反应阶段的因子和光反应阶段的因子。暗反应阶段因子有休眠卵的保存时间和保存处理方式。在 - 4℃下保存 0～ 62d内休眠卵的萌发率随保存时间增加而增加 ,保存 62～ 1 80d内休眠卵的萌发率有略微下降的趋势。保存时间在 62d内 ,保存处理方式以 - 4℃冷冻效果最好 ,萌发率为2 2 0 % ,干燥和干湿循环组次之 ,萌发率分别为 6 0 %和 8 5%。光反应阶段因子有光照、盐度、温度 ,其中光照是休眠卵萌发的首要条件 ,盐度的作用仅次于光照 ,盐度和温度对休眠卵萌发没有交互作用。盐度极显著影响萌发率和萌发速率 ,1～ 1 0为萌发最适盐度 ,1 0盐度组萌发率最高 ;1盐度组萌发速率最快 ,2 0盐度组次之 ,30盐度组最慢。温度只影响萌发速率 ( 30℃温度组萌发速率最快 ,2 5℃温度组次之 ,2 0℃温度组最慢 ) ,但并不影响萌发率。蒙古裸腹氵蚤的生物学零度约为 1 1℃。
The dormant egg germination experiments showed that the factors that affect the dormancy ovipositing dormancy eggs of M. mongolica were dark reaction stage and photoreaction stage. Dark reaction stage factors have dormant eggs to save time and save the way. The germination rate of dormant eggs from 0 to 62 days stored at -4 ℃ increased with the increase of preservation time, and the germination rate of resting eggs decreased slightly from 62 to 180 days. The storage time was within 62d, the preservation treatment was the best at -4 ℃, the germination rate was 220%, followed by the dry and wet-dry cycles, the germination rates were 60% and 85% respectively. There were light, salinity and temperature in the photoreaction stage, of which light was the most important condition for dormancy eggs to germinate, and salinity was second only to light. Salinity and temperature had no interaction on dormant eggs. The salinity significantly affected the germination rate and germination rate. The optimum salinity was 1 ~ 10 and the highest salinity was found in 10 salinity group. The fastest salinity was observed in 1 salinity group, followed by 30 salinity group and 30 salinity group Degree of the slowest group. Temperature affected germination rate only (30 ℃ temperature group germination rate fastest, 25 ℃ temperature group followed, 20 ℃ temperature group slowest), but does not affect the germination rate. The biological abundance of the Mongolian mumpty sucker flea is about 1 1 ℃.
