摘要: 棕榈蓟马在茄子上的种群增长,用种群增长模型来分析,露地栽培的成虫、若虫种群增长率r分别为0.0630和0.0801,设施栽培分别为0.0983和0.1036.设施栽培的逻辑斯蒂曲线的K值为33.90,明显大于露地栽培的K值23.50.棕榈蓟马种群在茄子上空间分布调查结果,成、若虫的M*-M回归式分别为M*=0.6011+1.468M和M*=7.2515+2.0640M.成虫+若虫的M*-M回归式为M*=7.5138+1.9119M.在每抽样单元平均密度在10~100头时,所需样本数量为78~44.

Abstract: Population growth of Thrips palmi Karny on eggplant (Solanum melongena L.) were analyzed by mathematical models.The rate of population increase (r) of the adults and immature (instars 1~2) T.palmi were estimated to be 0.0630 and 0.0801 respectively in the open fields, and 0.0983 and 0.1036 respectively in the greenhouse. K value of logistic curve of T.palmi was estimated to be 33.90 in the greenhouse, and 23.50 in the open fields. The relationship between mean crowding (M*) and mean density (M) of T.palmi per eggplant leaf were estimated by Iwao's M*-M regression.The regression equation of adult and immature T.palmi on eggplant were:M*=0.6011+1.468M and M*=7.2515+2.064M respectively. The regression equation of the number of adult and immature was M*=7.5138+1.9119M.When the population density of the adults and immature T.palmi per eggplant leaf were 10 to 100, the number of sampling should be 78 to 44.
