| 摘 要： | 通过调查分析,明确了龙眼长跗萤叶甲(Monolepta occifuvis Gressitt et Kimoto)成虫在龙眼园的空间分布型为聚集分布,在田间调查龙眼长跗萤叶甲成虫种群数量时可采用棋盘式、直线跳跃式或五点式抽样,其中以棋盘式较好。通过Iwao—Kuno理论抽样数学模型确定了在一定水平下的理论抽样数。

| Abstract: | The spatial distribution pattern of adult Monoleptu occifuvis Gressitt et Kimoto was the aggregation pattern. "Five-point-pattern" or " chessboard-pattern" or "straight-leap-pattern" were a-dopted when investigating the density of adult in longan field. It was found that the best method was "chessboard-pattern". The sample size requirements at particular level were determined using Iwao-Kuno's theoretical sampling mathematic model. |
