| 摘 要： | 为评价矿物油乳剂(petroleum-based horticultural mineral oils,HMOs)对柑橘木虱Diaphorina citri Kuwayama (Hemiptera: Liviidae)的防治效果,在封闭空间的柑橘苗上分别设计喷施清水及0.25%、0.5%、1%、2% 4个体积分数的HMOs,调查柑橘木虱成虫在柑橘植株上的定殖率,以同样的药剂设计进行田间柑橘木虱若虫防治效果试验。结果显示,喷施1次HMOs后移入柑橘木虱,1~2 d柑橘木虱在柑橘植株上的定殖显著(P<0.05)降低,在9 d内显著(P<0.05)降低柑橘木虱在柑橘叶片上的产卵量,但在后期失去控制效果;喷施2次HMOs持续控制柑橘木虱在柑橘苗上的定殖效果优于喷施1次HMOs;喷2次HMOs后移入柑橘木虱22 d,2% HMOs处理柑橘木虱定殖比为0.15。在喷施2次HMOs后移入柑橘木虱、在移入柑橘木虱前后喷施2次HMOs和移入柑橘木虱后喷施2次HMOs的方案中,以移入柑橘木虱后喷施2次HMOs的方案最佳。田间试验表明,喷施1%和2% HMOs后2~14 d对柑橘木虱若虫防效均保持在100%,0.5% HMOs处理的防效在87.15%~90.81%,而0.25% HMOs处理防效在25.81%~34.73%,0.5%~2% HMOs处理对柑橘木虱若虫均有较高的防治效果。在柑橘黄龙病发生区,柑橘木虱发生高峰期时,采用0.5%~1% HMOs 2次以上,隔1周喷施1次,可有效控制柑橘木虱。

| Abstract: | In order to evaluate the control efficacy of petroleum-based horticultural mineral oils(HMOs)against Diaphorina citri Kuwayama (Hemiptera: Liviidae), the colonization rate of the adult Diaphorina citri on the citrus plants were investigated with four volumn fractions of HMOs in 0.25%, 0.5%, 1% , 2% and water control sprayed on the citrus seedlings in the closed space. Meanwhile, the control efficiency of HMOs on Diaphorina citri nymph were evaluated with the same experimental design. It was showed that when the adult Diaphorina citri were released after spraying HMOs on the citrus seedlings once, the number of adults/plant within 1 to 2 days and eggs/plant in 9 days significantly reduced (P<0.05); however, the control effect was not obvious in the later stage. The numbers of the adult Diaphorina citri per plant after spraying HMOs on the citrus seedlings twice was fewer than spraying once. When the adult Diaphorina citri were released after spraying 2% HMOs on the citrus seedlings twice, the colonization ratio of the adult Diaphorina citri was 0.15 after 22 days. Among the treatments that adult Diaphorina citri released after spraying HMOs on the citrus seedlings twice, spraying HMOs on the citrus seedlings before and after the release of adult Diaphorina citri, and the adult Diaphorina citri released before spraying HMOs on the citrus seedlings twice, the best treatment was the adult Diaphorina citri released before spraying HMOs on the citrus seedlings twice. The result of field trial showed that the control efficacy of spraying 1% and 2% HMOs on the Diaphorina citri nymph remained 100% within 2-14 days, the control efficacy of 0.5% HMOs treatment was between 87.15%-90.81%, the control efficacy of 0.25% HMOs treatment was between 25.81%-34.73%. 0.5%-2% HMOs provided excellent control efficacy on the Diaphorina citri nymph consequently. It was suggested that Diaphorina citri could be well controlled by spraying 0.5%-1% HMOs twice or more every other week in the peak occurrence at the area of Huanglongbing disease. |
