1984年以来,我们在云台山南麓云台乡虎窝果林场进行錪钨灯远距离照射,配合黑光灯诱杀赤松毛虫(Dendrolimus speetabilis Butler)成虫的试验。当笔者在黑光灯下统计诱蛾量时,发现家犬(Canis amiliaris)捕食赤松毛虫成虫,迄今未见报道,现特作简报如下: 7月中旬云台山区气温较高,时正赤松毛虫羽化盛期,在这段时间里,我们每晚20:30开灯诱杀赤松毛虫成虫,见家犬四处活动觅食,并三五成群聚集在架设诱蛾灯的谷场和林缘平缓地处,争相捕食被架设6米高的碘钨灯(1000W)远距离诱来后,又被设置距地面50厘
Since 1984, we have conducted long-distance irradiation of tungsten lamp in Huwo Fruit Farm of Yuntai Township at the south of Yuntai Mountain to cope with adults of Dendrolimus speetabilis Butler with black light. When the author statistics the quantity of moth in black light, we found that Canis amiliaris preyed on adult of C. Dendrolimi. Up to now, it has been reported as follows: In mid-July, the temperature in Yuntai Mountain was high, During this period of time, at 20:30 every night, we turned on the lights to trap the adults of Dendrolimus punctatus. We saw the activities of the dogs in their foraging places and the gathering of three or five flocks at the valley and the edge of the forest where the lure lamp was installed. , Competing for prey was erected 6-meter-high iodine tungsten lamp (1000W) after long-range lure, and was set 50% from the ground
