1.本文就鸡新勋恙螨幼虫在不同温湿度,不同温度的水,及低温等不同环境中的生活力作一初步研究。 2.鸡新勋恙螨幼虫在18±1℃,相对湿度73％;26—29℃,相对湿度50—52％;34±1℃,相对湿度50％;40±1℃,相对湿度45％;45±1℃,相对湿度37％;50±1℃,相对湿度34％;56±1℃;相对湿度30％;61±1℃,相对湿度28.5％时分别可活26小时20分;12小时;9小时;5 1/2小时;2小时40分;100分;40分;10分。说明幼虫有相对的抗旱性能。 3.鸡新勋恙螨幼虫在28±1℃;34±1℃;40±1℃;50±1℃,56±1℃;61±1℃;65±1℃的水中,未饱食的幼虫分别可活77天;29天;26天;10小时;40分;40分;20分钟。幼虫虽然在上列的温度中或经过該温度处理后尚能具有发育为稚虫的能力,尤以40±1℃以下为显见,由此可知幼虫对高湿度适应的性能。 4.鸡新勋恙螨幼虫在0℃;-5℃;-10±1℃时分别可活32天;23天;3天。也说明了它的御寒能力。 5.基于上述的秸果,鸡新勋恙螨幼虫都是在室温中迅速转变为高温或低温的情况下就产生这样快的适应力,故就它在鸡螨痘病的流行、发生及防治等方面加以分析和探讨。
1. In this paper, Chixinxun chigger larvae in a different temperature and humidity, water at different temperatures, and low temperature in different environments for a preliminary study of the viability. 2. Chick Xun Chigger larvae at 18 ± 1 ℃, relative humidity 73%; 26-29 ℃, relative humidity 50-52%; 34 ± 1 ℃, relative humidity 50%; 40 ± 1 ℃, relative humidity 45% 45 ± 1 ℃, relative humidity 37%; 50 ± 1 ℃, relative humidity 34%; 56 ± 1 ℃; relative humidity 30%; 61 ± 1 ℃, relative humidity 28.5% Hours; 9 hours; 5 1/2 hours; 2 hours 40 minutes; 100 minutes; 40 minutes; 10 minutes. Shows larvae have a relative drought resistance. 3. Chicken Newton chigger larvae at 28 ± 1 ℃; 34 ± 1 ℃; 40 ± 1 ℃; 50 ± 1 ℃, 56 ± 1 ℃; 61 ± 1 ℃; 65 ± 1 ℃ in water, Larvae can live 77 days; 29 days; 26 days; 10 hours; 40 minutes; 40 minutes; 20 minutes. Although the larvae still have the ability to develop into larvae at or above the temperature listed above, especially below 40 ± 1 ° C, the larvae can adapt to high humidity performance. Chicken Newton chigger larvae at 0 ℃; -5 ℃; -10 ± 1 ℃, respectively, can live 32 days; 23 days; 3 days. Also shows its ability to keep warm. 5. Based on the above results, chick moth chickens mite larvae are rapidly adapting to high temperatures or low temperatures at room temperature, so it has been shown to be prevalent, occurring and preventing Etc. to be analyzed and discussed.
