Abstract:

Apophylia flavovirens (Fairmaire) is one new pest to Salvia miltiorrhiza Bunge．The spacial distribution pattern of the Adults of Apophylia flavovirens (Fairmaire) in salvia Fields and its sampling model were studied in this paper in order to know well its ecological characteristic and effective sampling model．The results showed that the spatial distribution pattern of Apophylia flavovirens (Fairmaire) conformed to the negative binomial distribution in field. It was also tested that the distribution pattern was aggregative distribution by aggregation indexes，which was caused by environmental heterology with lower density and by environmental heterology and their aggregative characteristic with their higher density. The result was further proved by the use of Toylar's and Iwao's methods, and the individual of Apophylia flavovirens (Fairmaire) adults excluded each other. The aggregative level increased along with the increasing of their population density. The models of theoretical sampling of Apophylia flavovirens (Fairmaire) adult in salvia Field had been set up.
