杭白菊绿盲蝽生物学习性及其在不同品种菊花上分布差异
摘 要：为探讨绿盲蝽在杭白菊上生物学习性、比较其对于3个主栽品种菊花的嗜好性，遂将其各个虫态养于菊苗上，逐日观察，描述了各个虫态形态特征，记述了若虫各龄历期、成虫历期天数。盛花期的田间调查发现：晚小洋菊花上绿盲蝽个数最多（21.5±3.6头/330cm2），早小洋菊花上的个数略次之（19.1±4.5头/330cm2），异种大白菊花上的最少（7.5±1.5头/330cm2），前2个品种与后1个品种虫数差异皆显著。连续4日，每块黄板、绿板和白板上累积诱捕绿盲蝽平均数分别为9.5±1.6头、8.1±1.7头和4.9±1.2头，前2个品种与后1个品种差异分别达显著水平。认为菊花香气和黄色可引诱绿盲蝽。

Abstract：In order to discuss the biology habit of Apolygus lucorum on Chrysanthemum Cultivar ‘Hangbaiju’，and compare its preference to the flowers of three elite cultivars，its various developmental stages were reared on the flowers and observed every day. The morphological characters of each developmental stages were described，and the duration of every instar nymph and adult was recorded. The investigation results in the full-bloom stage showed that density of the bug on cultivar ‘Wanxiaoyangju’ was the highest （21.5±3.6/330 cm2），and the density on cultivar ‘Zhaoxiaoyangju’ was the slightly lower （19.1±4.5/330 cm2），and that on cultivar ‘Yizhongdabaiju’ was the lowest （7.5±1.5/330 cm2）. The difference between anyone of the former two cultivars and the last one reached the significant level. The average of the...
