近年来,东北鼢鼠(Myospalax psilurus)严重危害林场樟子松(Pinus sylvestris var.mon-golica)人工林,啃食根部,被害樟子松轻则生长衰弱,重则死亡。如黑龙江省泰来县东方红林场1987年受害面积11,500亩,受害率6.5％,死亡率4.1％。碾子山区华安林场8—10年的樟子松人工林1987年受害面积5,000亩,受害率最高地块达31％,死亡率达12.5％。为此,我们于1988年3—5月用有机磷毒剂——毒鼠磷(Phosacetim)防治东北鼢鼠。现将室内药效观察、选择摄食性以及现场灭鼠效果等报道如下:
In recent years, the Myospalax psilurus severely endangered Pinus sylvestris var. Mon-golica plantation and eaten the root, while the Pinus sylvestris var. For example, the Dongfanghong Forest Farm in Tailai County, Heilongjiang Province, suffered an area of 11,500 mu in 1987 with a victimization rate of 6.5% and a mortality rate of 4.1%. The 8-10 year Pinus sylvestris plantation in Huaan Forest Farm of Nianzishan Mountain suffered from an area of 5,000 mu in 1987 with the highest damage rate reaching 31% and the death rate reaching 12.5%. To this end, we used the organophosphate poisons, Phosacetim, to control Northeast zokor from March to May 1988. Indoor efficacy now observation, the choice of feeding and on-site deratization effects reported as follows:
