摘　　要：为有效诱捕柑橘大实蝇Bactrocera minax成虫,首先调查5个不同橘园中柑橘大实蝇成虫发生量和落果数量,计算落果率,对诱捕时间和诱捕成虫百分比进行Logistic方程拟合分析,然后调查全田、橘园、交界带、杂树林、橘园中心5个生境下柑橘大实蝇觅食高峰期成虫发生量,并对各生境下柑橘大实蝇成虫发生量和各橘园中落果率进行相关性分析及回归分析。结果表明,觅食高峰期柑橘大实蝇的最佳诱捕时间为5月31日—6月27日。除杂树林外,觅食高峰期全田、橘园、交界带和橘园中心柑橘大实蝇成虫发生量和落果率之间均呈显著正相关。通过比较5个生境拟合回归方程的判定系数和均方根误差确定在交界带生境中柑橘大实蝇成虫发生量与落果率的二次三项式模型拟合效果最好,因此,交界带为柑橘大实蝇成虫的最佳诱捕地点。In order to effectively trap Chinese citrus fruit fly Bactrocera minax adults,the occurrence of adults and the number of fallen fruits were investigated in five different citrus orchards;the fruitdropping rate was calculated,and the trapping time and trapping percentage of adults were fitted using the logistic equation.The occurrence of B.minax adults was next investigated during the peak foraging period in the entire field,citrus orchards,junction zones,hybrid woods and the center of citrus orchards,and correlation analysis and regression analysis were carried out between the occurrence of adults and fruit-dropping rate in the five habitats.The results showed that the optimal time for trapping B.minax during the peak foraging period was from May 31 to June 27.In addition,except in the hybrid woods,there was a significant positive correlation between the occurrence of adults and the fruit-dropping rate in the entire field,citrus orchards,junction zones and the center of citrus orchards.However,by comparing the coefficient of determination and root mean square error of regression equations in five different habitats,the quadratic trinomial model of adult occurrence and fruit-dropping rate had the best fit in junction zones,indicating that it was the optimal location for trapping B.minax adults during the peak foraging period.
