摘要:

目的: 研究水杉、枫香、构树、毛白杨、木瓜、鹅掌楸、白蜡等7种非悬铃木方翅网蝽的寄主植物叶片挥发物对其成虫具有显著引诱作用而未成为其寄主的原因,为配置非寄主植物或利用非寄主植物提取物防控悬铃木方翅网蝽提供依据。方法: 研磨、过滤获取这7种非寄主植物叶片的粗提物,以粗提物饲喂悬铃木方翅网蝽成虫,测定对其存活的影响。以粗提物原液和不同体积分数的稀释液涂抹悬铃木叶片,测定对悬铃木方翅网蝽成虫的忌避活性。结果: 7种非寄主植物叶片粗提物原液饲喂的悬铃木方翅网蝽成虫的生存状况显著低于对照(清水)(P<0.05),其半致死时间、99%致死时间和平均存活时间均极显著短于对照(P<0.01),其中木瓜尤为明显。7种非寄主植物叶片的粗提物原液对悬铃木方翅网蝽成虫均具有忌避效果,忌避率最高的为构树(74.84%),其次是白蜡(70.74%)、枫香(53.90%)、木瓜(53.33%)、水杉(51.66%)、毛白杨(49.47%)、鹅掌楸(43.19%)。粗提物稀释后,忌避效果降低,但忌避效果并非随体积分数降低呈单向递减。结论: 嗅觉上有吸引作用的水杉、枫香、构树、毛白杨、木瓜、鹅掌楸、白蜡等7种植物叶片粗提物中含有对悬铃木方翅网蝽成虫有毒杀作用或(和)忌避作用的物质,可能是这些植物未能被悬铃木方翅网蝽利用的原因之一。7种植物中,构树提取物对悬铃木方翅网蝽的忌避作用最强,木瓜提取物对网蝽的毒杀作用最大, 可进一步研究二者在悬铃木方翅网蝽防控中的可能应用。

Abstract:

Objective: The main purpose of this paper is to study the reasons that seven plants, including Metasequoia glyptostroboides, Liquidambar formosana, Broussonetia papyrifera, Populus tomentosa, Chaenomeles sinensis, Liriodendron chinense and Fraxinus chinensis do not become the hosts of Corythucha ciliata although the volatiles from the leaves of these seven plants have a significant attracting effect on C. ciliata adults, soas to provide a basis information for the use of non-host plants by tree species arrangement or their extracts to prevent and control C. ciliate. Method: The crude extracts from the leaves of the seven non host plants were obtained by grinding and filtration. The crude extracts were fed to the adults of C. ciliata to determine the impact on their survival. The crude extracts and dilutions of different volume fraction were applied to the leaves of Platanus acerifolia to determine the repellent activity against the adults of C. ciliata. Result: The survival status of C. ciliata adults fed with crude leaf extracts of 7 non-host plants was significantly lower than the control (water), and the median lethal time, 99% lethal time and average survival time were extremely significant shorter than those of C.ciliata adults treated with water, especially C. sinensis. The crude extracts from the leaves of the seven non-host plants all have repellent effects on C. ciliata adults. The highest repellent rate was B. papyrifera (74.84%), followed by F. chinensis (70.74%), L. formosana (53.90%), C. sinensis (53.33%), M. glyptostroboides (51.66%), P. tomentosa (49.47%) and L. chinense (43.19%). When the crude extracts were diluted, the repellent effects decreased, but the effects did not decrease unidirectionally with the decrease in volume fraction. Conclusion: That the crude extracts of these seven non-plant which have an attractive olfactory effect, contain substances that are toxic or and repellent to the adults of C. ciliata, may be one of the reasons why these plants are not used by C. ciliata. Among the seven plants, the extracts of B. papyrifera had the strongest repelling effect and the extracts of C. sinensis have the greatest toxicity to C. ciliata. The possible applications of the two plants in the control of C. ciliata can be studied further.
