一、两种菌生长发育需要的温度及其杀虫途径(一)白僵菌:白僵菌是一种虫生性的杀虫真菌,它能产生一种分生孢子,在一定的营养条件下,遇到适宜的温、湿度,分生孢子萌发形成芽管,继续生长成菌丝,最后菌丝又产生分生孢子。完成一个繁殖过程需要七天左右。而细菌靠分裂繁殖,繁殖一代仅需要一天左右的时间,所以,白僵菌不如细菌杀虫剂速效。白僵菌生长发育所需温、湿度:
First, the growth and development of two kinds of bacteria need temperature and insecticidal pathways (a) Beauveria bassiana: Beauveria bassiana is a wormy insecticidal fungus, it can produce a conidia, under certain nutritional conditions , Met the appropriate temperature and humidity, conidia germination germination tube, continue to grow into mycelium, and finally hyphae produce conidia. It takes about seven days to complete a breeding process. Bacteria rely on fission and multiplication, breeding a generation only takes about one day, so Beauveria bassiana is not as effective as bacterial pesticides. Beauveria bassiana growth and development of the required temperature and humidity:
