| 摘 要： | 为评价种衣剂防治玉米田双斑长跗萤叶甲的可行性，通过选用内吸性强、持效期长的种衣剂，设置常规剂量对玉米种子进行包衣处理，采取田间罩网小区试验，明确种衣剂对双斑长跗萤叶甲的防效及对玉米出苗、生长的安全性。结果表明，30%噻虫嗪FS、10%氟虫腈FSC、38%噻虫胺FSC、40%噻虫嗪·溴氰虫酰胺FS、30%噻虫嗪·氟虫腈FSC、30%噻虫胺·氟虫腈FSC、20%噻虫胺·氟啶虫酰胺FSC等7种种衣剂对玉米出苗、生长均安全；38%噻虫胺FSC有效成分用量7.6 g/kg种子处理对双斑长跗萤叶甲的防治效果为70.6%～78.5%,防效最好，显著高于除30%噻虫胺·氟虫腈FSC 7.5 g/kg处理外的其他种衣剂处理(P<0.05),并且可使双斑长跗萤叶甲成虫羽化出土始现期、出土高峰期推迟5～10 d,可以使成虫高峰期避开玉米吐丝期。玉米田双斑长跗萤叶甲防控前移推荐使用38%噻虫胺FSC,有效成分剂量为7.6 g/kg种子。

| Abstract: | In order to evaluate the feasibility of seed coating agents against Monolepta hieroglyphica in corn fields, several systematic insecticides with long lasting effect were selected to treat corn seeds at recommended dosages, and then the field experiments of covering plot with insect proof nets were used to clarified the control effect of seed coating agents against M.hieroglyphica and the safety of the seed coating agents to corn seedling and growth were also evaluated. The results showed that all seven seed coating agents, including thiamethoxam 30% FS, fipronil 10% FSC, clothianidin 38% FSC, thiamethoxam·cyantraniliprole 40% FS, thiamethoxam·fipronil 30% FSC, clothianidin·fipronil 30% FSC and clothianidin·flonicamid 20% FSC, were safe to the emergence and growth of corn seedlings. Clothianidin 38% FSC at the dosage of 7.6 g/kg seed provided the best control effect against M.hieroglyphica, with the efficacy ranged from 70.6% to 78.5%, followed by clothianidin·fipronil 30% FSC at 7.5 g/kg seed. Clothianidin 38% FS showed significantly better control effect against M.hieroglyphica than the other seed coatings except clothianidin·fipronil 30% FS (P<0.05), which can postpone the onset date and the peak date of M.hieroglyphica adults by 5-10 days. In this manner, the peak adult period of M. hieroglyphica would not overlap with the corn silking period. It is recommended to use clothianidin 38% FSC for seed treatment to control of M.hieroglyphica with the active ingredient dosage of 7.6 g/kg corn seeds in corn field. |
