根据甜菜夜蛾成虫飞行的生物学行为,设计出了一种结构合理、使用方便的实用新型诱捕器。在田间进行诱蛾试验,结果表明,该种诱捕器诱虫效果(平均总诱蛾量为171.5头)高于常用的水盆诱捕器(平均总诱蛾量为108.5头)和美国的Unitrap诱捕器(平均总诱蛾量为140头)。在使用过程中,操作简单、在能保证诱芯的充分散发的同时,能避免阳光直射和雨水直接冲刷诱芯。该种诱捕器几乎不受田间环境的限制,可常年使用。
A new type of pheromone-baited traps was designed basically on the flying behavior of beet armyworm adults. The results for capturing beet armyworm male moths in fields showed that the trap was significantly more effective than water pan traps usually utilized in China and the Uni:raps from America. The traps could be applied simply in fields any time and pro- tected attractant lures from rain erode, point-blank sun rays and be sure to enable the lures to emanate odor outside adequately. The trap could be applied perennially and hardly be restricted in fields.
