近日,有市民在长春公园发现,一处灯杆上挂着新物件,从远处看很像路灯,可它不是普通路灯,而是捕虫“法宝”,可以保护园内的绿植免受虫害。
5日上午,长春晚报记者来到长春公园,在一处绿化带附近,找到了市民所说的这件捕虫“法宝”。原来它是一台太阳能风吸式杀虫灯,在装置的顶部有一块太阳能接收板,其下方连着一处节能灯和一个铁箱子,装置处于待机状态。记者走近,透过铁皮箱子上的铁丝网,看到其内吸入了不少昆虫,其中很多已经死亡。市民曹先生也注意到了这个装置,他说:“我家住在附近的小区,经常到公园里来散步,听说这个捕虫器用的是太阳能,节能又环保。”
该装置是怎么捕虫的?它的捕虫效果如何?长春公园技术科付科长表示,这个装置是他们最近新引的,目前园内只安装这一台,正处于试验中。该装置白天储存太阳能,等到夜晚,装置上的节能灯就会亮起来,飞虫被光源吸引,这时感应装置启动,装置上的风扇就会加速运转起来,将节能灯附近的飞虫吸入铁皮箱内。通过试验,他们发现这个装置的捕虫效果良好,今后将在公园内进行推广,预计安装10台左右。
同时,为了保护园内绿植,该园还在树上悬挂了引诱捕虫装置,内有胶状物,可以诱捕美国白蛾等昆虫。
