摘要
浙江北部竹林面积很大,仅湖州市所辖的安吉、长兴、德清县和市郊就有8.67万ha,其中毛竹(Phyllostachys pubescens Mazel ex H.de Lehaie)7.33万ha。自70年代中期以来,连续遭受多种害虫危害,由于纯林居多,害虫一旦发生,便很快成灾。如1977年发生的竹螟危害面积达2.67万ha,当年枯死毛竹420多万株。1984年发生卵圆蝽(Hippota dorsalis(Stal))危害,面积也有1.2万ha。同时,近年一字竹象(Otidognathus dovidis Fair)、毛竹黑叶蜂(Eutomostathus nigritus Xiao sp.nev(Ms)和竹广肩小蜂(Aiolomorphus rhopaloides Walker)等害虫,也分别在安吉。
North of Zhejiang Province is a main bamboo-producing district. The bamboo forest is not only in large areas, but also has a concentrated distribution. In recent years, as many bamboo suffer damage by Algedonia coclesalis, Circobotys aurealis, Eumorphobotys obscuralis, Demobotys pervulgalis, Crocidophora evenoralis, Hippota dorsalis, Eutomostethus nigritus, Aiolomophus rhopaliodes, Otidognathus davidis etc. A large part of bamboo stands have withered and become chloratic, some bamboos even died. This cause farmer's enormous economic losses. After testing for many years, it is clear that injecting Tamaron into bamboo carity to control the vatious bamboo insect pests reached a mortality of over 95％. The residue of Tamaron in the bamboo shoots of current year contains some residual Tamaron with the highest amount on the tenth day after injection and gradually decreasing day by day. The residue of Tamaron could not been found in the bamboo shoots coming out next year. Even the highest amount of the residue of Tamaron on the tenth day after injection is only 23.8—47.5％, which is lower than the standard for edible vegetable.
