中文摘要:
在室内选择上海地区的19科27种园林植物对悬铃木方翅网蝽Corythucha ciliata(Say)进行寄主专一性测定。非选择性试验结果表明:悬铃木方翅网蝽对一球悬铃木(Platanus occidentalis)、二球悬铃木(Platanus acerifolia)、三球悬铃木(Platanus orientalis)、红叶李(Prunus cerasifera)、构树(Broussonetia papyrifera)和红花槭(Acer rubrum)6种植物有取食现象,其中若虫在前5种植物上取食量较大,而对红花槭只表现为轻微取食;成虫在前4种植物上的取食量较大,而对构树和红花槭只有少量取食。在所有植物中,悬铃木方翅网蝽只能在一球悬铃木、二球悬铃木、三球悬铃木上完成完整的发育世代。选择性试验表明:成虫嗜食一球悬铃木、二球悬铃木、三球悬铃木,部分取食红叶李,而不取食红花槭和构树。成虫产卵显著偏爱于一球悬铃木、二球悬铃木、三球悬铃木,而不在其它植物上产卵。因此,悬铃木方翅网蝽的寄主范围较为单一,只有悬铃木属植物是其寄主。
英文摘要: The host preferences of Corythucha ciliata (Say) were tested with 27 plant species from 19 families in a laboratory in Shanghai. A non-choice trial showed that although nymphs could feed on Platanus occidentalis, Platanus acerifolia, Platanus orientalis, Prunus cerasifera, Broussonetia papyrifera and Acer rubrum, they ate more of P. occidentalis, P. acerifolia, P. orientalis, P. cerasifera and B. papyrifera. Adults could also feed on all of the above 6 plants but preferred P. occidentalis, P. acerifolia, P. orientalis and P. cerasifera. C. ciliata could only complete its life history on P. occidentalis, P. acerifolia and P. orientalis. A choice test confirmed that adults preferred P. occidentalis, P. acerifolia and P. orientalis; although some could eat P. cerasifera none fed on A. rubrum and B. papyrifera. Adults only laid eggs on P. occidentalis, P. acerifolia and P. orientalis. Thus, the host range of C. ciliata is essentially restricted to plants of the genus Platanus.
