水分是一切生物体不可缺少的基本生活物质,正常的生理活动要有一定范围的含水量才能保证。任何生物体丧失了水分或者水分过多,都会影响其生命活动,昆虫也是这样。昆虫对湿度的要求同温度一样严格,在适宜的湿度范围内,昆虫生长发育较快,繁殖力强,寿命也长。一般来说,大部分昆虫的最适宜湿度范围大约在相对湿度70%至90%之间。但各种害虫对湿度的要求不一样,如棉蚜虫和很多红蜘蛛适宜生活在湿度比较低的环境里(相对湿
Moisture is an indispensable basic living material for all living organisms. Normal physiological activity requires a certain range of water content to be guaranteed. Anything that loses its body of water or has too much moisture affects the life of any organism, as do insects. Insects on the humidity requirements as stringent temperature, in the appropriate humidity range, rapid growth and development of insects, fertility and long life expectancy. In general, most insects have an optimum humidity range of about 70% to 90% relative humidity. However, the requirements of various pests on the humidity is not the same, such as cotton aphids and many spider mites suitable for living in relatively low humidity environment (relative humidity
