利用生命表的方法和干扰作用控制指数评价了非嗜食植物次生化合物对荔枝蒂蛀虫 (ConopomorphasinensisBradley)的控制作用 ,结果表明 :在室内 ,供试的 2 4种植物乙醇提取物中对荔枝蒂蛀虫成虫产卵驱避作用较好的有白花非洲山毛豆 (Tephrosiavogelli)、飞机草 (Eupatoriumodoratum)和大叶桉 (Eucalyptusrobusta)的乙醇提取物 ,其干扰作用控制指数分别为 0 10 9、0 112、0 12 7,即它们的驱避作用效果在 80 %～ 90 %之间 ;在田间 ,白花非洲山毛豆、飞机草和大叶桉的乙醇提取物以及 φ =10 %高效灭百可乳油 (30 0 0× )和 φ =90 %敌百虫结晶 (5 0 0× )处理区中 ,荔枝蒂蛀虫的种群趋势指数分别为 2 817、3 2 0 6、3 86 3、7 95和 11 84 ,表明荔枝蒂蛀虫下一代的种群数量将分别为当代的 2 817、3 2 0 6、3 86 3、7 95 0和 11 84 0倍 .各处理区的干扰作用控制指数分别为 0 2 0 9、0 2 38、0 2 86、0 5 89和 0 877,表明非洲山毛豆、飞机草和大叶桉的乙醇提取物处理区对荔枝蒂蛀虫的防治效果可达 70 %以上 ,而高效灭百可乳油和敌百虫结晶的防治效果均低于 4 0 % .
The method of life table and the control index of disturbance were used to evaluate the control effect of non-viable plant secondary compounds on Conopomorphas sinensis Bradley. The results showed that in the 24 ethanol extracts of plants tested, The adults with good repellent effect of oviposition had ethanol extract of Tephrosia vogelli, Eupatorium odoratum and Eucalyptus robusta with the control index of interference of 0 10 9,0 112,0 12 7, that is, the effect of their repellent effect was between 80% and 90%. In the field, the ethanol extracts of white soybean, soybean grass and Eucalyptus globulus, as well as 10% 0 ×) and φ = 90% of the trichlorfon (500 ×) treatment zone, the trend indices of litchi stem borers were 2 817, 3 2 0 6, 3 86 3, 7 95 and 11 84 respectively The population of the next generation of Lychee dorsalis will be respectively 2 817,3 2 0 6,3 86 3,7 95 0 and 1 84 0 times the current generation.The control indexes of disturbance in each treatment area are 0 2 0 9,0 2 38,0 2 86,0 5 89 and 0 877, table Africa Tephrosia, odorata and Dayean ethanol extract treatment zone to control effects of C. sinensis up to 70%, while FASTAC EC and trichlorfon crystal can control effects were lower than 40%.
