摘要
于2016年3月对云南铜壁关国家级自然保护区内萼翅藤(Calycopteris floribunda(Roxb.)Lam.)的访花昆虫的种类、访花频率、停留时间等进行了观测。结果表明:萼翅藤访花昆虫仅有9种,分属于鳞翅目、膜翅目、双翅目、缺翅目;大多数昆虫的访花频率均小于5朵次,且停留时间均不超过80 s;温度高于25.5℃或低于18℃,几乎会使访花昆虫停止活动。访花昆虫种类少、访花频率低、停留时间短是导致萼翅藤濒危的主要因素。
The species, visiting frequency and resident time of flower-visiting insects on Calycopteris floribunda(Roxb.) Lam.(C. floribunda) in Yunnan Tongbiguan national nature reserve were observed in March 2016. The results showed that there were 9 species of flower-visiting insects on C. floribunda, which belonged to Lepidoptera, Hymenoptera, Diptera and Zoraptera. The visiting frequency of most visiting insects was below 5 times and the resident time was less than 80 seconds. The insects almost stopped visiting when the temperature was higher than 25.5 ℃ or lower than 18 ℃. The limited species, low visiting frequency and short resident time of the flower-visiting insects were the prime reasons causing the endangerment of C. floribunda.
