通过两年对斑啄木鸟啄食桑天牛越冬幼虫的系统观察表明,在斑啄木鸟种群密度约为0.37~0.55只/hm2时,其平均啄食率可达24.71%,啄食高峰期在1月份。用栽植构树饵树诱杀桑天牛成虫的方法,两年后使试验林有虫株率下降了51.3%~84.8%,取得了良好的效果
The systematic observation of overwintering larvae pecking on the spotted woodpeckers by spotted woodpecker for two years showed that when the density of spotted woodpecker population was about 0.37-0.55 / hm2, the average pecking rate was 24.71% Peak food in January. With the planted tree bait tree trapping and killing Morus alba adult method, two years later the experimental forest worm rate decreased by 51.3% to 84.8%, and achieved good results
