| Abstract: | In this paper,the population density investigation on larvea of Masso,pine caterpillar by using the method of long handle pruner bag-trap is introduced.The sampling technique of themethod is studied and the spatial distribution patterns of the injurous insect are analyzed. Themathematical models of probabilistic statistics are also analyzed and deduced.And the conversionbetween the pest density units and other problems are discussed.The method can overcome thedefects of the traditional method and its precision is higher than that of the traditional one and ithas certain practical value. |
