宜兴县地处江苏南部,境内多丘陵低山,气候温暖湿润,树种、植被比较丰富,为多种昆虫提供了良好的生活环境条件.这里白蚁种类较多、种群密度较大,就初步调查有土白蚁属(Odontotermes)、大白蚁属(Macrotermes)及散白蚁属(Reticulitermes)多种白蚁危害林木.特别是营造大片人工林后,白蚁的危害亦日趋严重.据我场杉木林136块标准地,13618株标准株危害情况调查,平均被害株率为58%,最高达98%.因此,防治白蚁已成为我场森保工作的重要内容.
Yixing County is located in southern Jiangsu Province, the territory of more hills and hills, warm and humid climate, species rich vegetation, for a variety of insects provides a good living environment conditions .There are more termite species, population density, the preliminary investigation Odontotermes species, Macrotermes species and Reticulitermes species are harmful to forests, especially after the large-scale planted forests are constructed, the damage of termites is becoming increasingly serious.According to the standard of 136 Chinese fir forests , 13618 strains of standard strains of the investigation, the average victim strain rate of 58%, up to 98% .Therefore, the prevention and treatment of termites has become an important part of our field of forest protection work.
