1982—1983年在新晃县调查了油桐尺蠖越冬蛹X(39块样地),卵块(30块样地)及小幼虫(30块样地)的分布型资料,用聚集度指标法及频次分布法进行检验。结果表明,除少数低密度的蛹样地符合泊松(随机)分布外,其余皆符合聚集分布。根据有蛹(卵块)株率与百株蛹(卵块)量的关系,导出了根据有蛹(卵株率查百株蛹(卵块)数的公式,可在实践中试用。对蛹期防治指标亦作了讨论。 油桐尺蠖(Buzura suppressaria Guenee)是油桐、油茶及茶叶的重要害虫。1982—1983年作者在湖南新晃县波洲公社红岩油桐林场及大湾罗公社毛溪大队(两地相距50多公里)研究了1982年越冬蛹,1983年第一代卵、2—3龄幼虫的空间分布型。
In 1982-1983, the distribution data of overwintering pupae X (39 plots), egg blocks (30 plots) and small larvae (30 plots) were investigated in Xinhuang County. Frequency distribution method for testing. The results showed that, except for a few low-density pupae, the distribution was consistent with Poisson (random) distribution. According to the relationship between the rate of pupae (eggblock) and the quantity of one hundred pupae (eggblock), the formula of pupae (eggblock) Also discussed. Buzura suppressaria Guenee is an important pest of tung tree, camellia and tea. 1982-1983 author in the county of Hunan Xinguang Po Hong Hongtongtong forest farm and the Grand Bay Luo commune Mao stream unit (More than 50 km apart) studied the spatial distribution pattern of overwintering pupae in 1982, the first generation eggs in 1983, and the second instar larvae.
