中文摘要:
      柑橘全爪螨是重要的柑橘害虫之一, 对多种化学农药已产生抗性。为合理选择防治药剂, 更好地防治该害虫, 本研究选择7种药剂采用改进浸叶法对柑橘全爪螨雌成螨进行了室内毒力测定, 并参照农药田间药效试验准则开展了田间药效试验。研究结果表明, 7种药剂对柑橘全爪螨的毒力从大到小依次为乙唑螨腈(0.818 mg/L)、丁氟螨酯(4.645 mg/L)、印楝素(4.878 mg/L)、氟啶胺(16.844 mg/L)、哒螨灵(21.167 mg/L)、乙螨唑(69.834 mg/L)、螺虫乙酯(417.089 mg/L)。乙唑螨腈和丁氟螨酯的速效性好且持效期长, 对柑橘全爪螨的防效显著高于其他供试药剂, 可作为防治的首选药剂。此外, 氟啶胺对柑橘全爪螨也有较高的毒力和防效, 作为一种广谱高效的保护性杀菌剂, 可在防治柑橘病害的同时防治害螨, 病虫兼治。
英文摘要:
      Citrus red mite Panonychus citri is an important pest of citrus, which has developed resistance to many chemical agents. The toxicities of seven acaricidal agents were measured in the laboratory and then field trials were surveyed against citrus red mites, according to the Guidelines for the field efficacy trials by using the method of whole plant spraying. The results showed that the LC50 values for of the tested insecticides were 0.818 mg/L (SYP-9625), 4.645 mg/L (cyflumetofen), 4.878 mg/L (azadirachtin), 16.844 mg/L (fluazinam), 21.167 mg/L (pyridaben), 69.834 mg/L (etoxazole) and 417.089 mg/L (spirotetramat). The field trials showed that 30% SYP-9625 30% SC and cyflumetofen 20% SC had better quick-acting and long-lasting effects on citrus red mites than others. Among all chemical agents, fluazinam, as a broad-spectrum efficient fungicide, can be used not only for the control of citrus red mite, but also for the prevention of citrus diseases.
