兰象属(Orchidophilus Buchanan)目前世界已知6种,寄主均为兰科(Orchidaceae)植物,其中以突胫兰象(Orchidophilus aterrimus)发生最为普遍,对兰花种植业危害最大。突胫兰象的卵、幼虫、蛹和成虫均可随寄主植物的调运而远距离传播,我国尚无发生记录。本文对该虫的形态特征、分布、寄主、生物学特点和防治方法进行了简要介绍,并对其入侵我国的可能性进行了讨论,进而提出相应的预防建议。
Orchidophilus Buchanan There are 6 kinds of Orchidophilus Buchanan currently known in the world. All Orchidophilus hosts are Orchidaceae plants, of which Orchidophilus aterrimus is the most common and most harmful to orchid cultivation. The eggs, larvae, pupae and adults of the tibia can be transported long distances with the host plants, and no records have been recorded in our country. In this paper, the morphological characteristics, distribution, hosts, biological characteristics and control methods of this pest were introduced briefly. The possibility of invasion into our country was also discussed, and then the corresponding prevention suggestions were put forward.
