| 中文摘要 |
| 本文通过使用罩笼接虫、林中置木招引、模拟酸雨试验小区置木招引的研究方法,对马尾松次期性害虫进行了招引试验.结果表明,受酸雨危害和用酸水处理的试材与对照试材相比,均易遭小蠹、天牛、象虫等次期性害虫的入侵危害.试材平均每100cm2表面积虫孔数分别高2.2—3,0.5—1.6,0.8—1.0个. |
| 英文摘要 |
| An Attempt has been made in this research that how mas-son pines get withered in the presence of acid rain in Southwest China and that what relations exist among the pine withering, insect pests and acid rain. Tow experimental areas were selected at Nanshan forestry station, nearby Chongqing City and at Huitong ' Forest Ecological Station of Hunan Province.Different test materials (of masson pines) that had been treated with pH 2, pH 3 and pH 4.5 respectively were bound together on the trees in these areas on purpose to attract the periodic insect pests. The results showed that the materials affected by acid rain or treated with acid water were susceptible to invasion of some pests such as the weevils, cerambycids and small insects. |
