| 基于同时防治水稻二化螟及稻纵卷叶螟的杀虫药剂较少的现状, 2014年采用田间小区试验探索了有机磷类、沙蚕毒素类、酰肼类、多杀菌素类、取代苯基吡唑类、缩氨基脲类、噁二嗪类、大环内酯抗生素类及双酰胺类等9类16种杀虫剂对二化螟和稻纵卷叶螟的防治效果。结果表明, 200 g/L氯虫苯甲酰胺SC和10%阿维?氟酰胺SC能有效控制二化螟和稻纵卷叶螟危害, 且速效作用好、持效期长达28 d, 药后7~28 d对二化螟和稻纵卷叶螟的防治效果分别为84.85%~93.37%和80.40%~86.16%。60 g/L乙基多杀菌素SC、1.8%阿维菌素EC、20%氟苯虫酰胺WG、40%氯虫?噻虫嗪WG、6%阿维?氯苯酰SC和10%四氯虫酰胺SC对二化螟的防治效果好而对稻纵卷叶螟有一定的兼治作用, 药后7~28 d防治效果分别为81.13%~97.17%和62.17%~85.26%。240 g/L氰氟虫腙SC对稻纵卷叶螟的防治效果好而对二化螟有较好的兼治效果, 药后7~28 d防治效果分别为76.98%~92.16%和76.37%~80.98%。1%甲氨基阿维菌素苯甲酸盐ME对二化螟及稻纵卷叶螟的防治效果较好, 速效性好且持效期较长, 药后7~28 d防治效果分别为69.29%~83.61%和68.84%~82.95%。此外, 5%丁虫腈EC和30%茚虫威WG分别对二化螟和稻纵卷叶螟高效, 而20%三唑磷EC、40%水胺硫磷EC、29%杀虫双AS和240 g/L甲氧虫酰肼SC难以有效控制二化螟和稻纵卷叶螟危害。在水稻生产实践中, 建议轮换使用双酰胺类和大环内酯抗生素类杀虫剂、乙基多杀菌素和氰氟虫腙防治二化螟和稻纵卷叶螟。 |

| Based on the scarcity of insecticides for controlling the striped stem borer, Chilo suppressalis, and rice leaf-roller, Cnaphalocrocis medinalis, field plot experiments were conducted to investigate control efficacy of 16 insecticides from 9 series, including organic phosphorus, nereistoxin, acylhydrazines, spinosads, substituted phenyl pyrazoles, semicarbazone, oxadiazine, macrolides antibiotics, diamides and etc, against the two pests in 2014. The results showed that excellent and quick control effect of 200 g/L chlorantraniliprole SC and 10% abamectin?flubendiamide SC on C. suppressalis and C.medinalis could be achieved within 28 days after treatment, with the control efficacies of 84.85%-93.37% and 80.40%-86.16%, respectively, 7-28 days after treatment. C.suppressalis was effectively controlled by 60 g/L spinetoram SC, 1.8% abamectin EC, 20% flubendiamide WG, 40% chlorantraniliprole?thiamethoxam WG, 6% abamectin?chlorantraniliprole SC and 10% SYP-9080 SC, and C.medinalis was also controlled to some extent, with the control efficacies of 81.13%-97.17% and 62.17%-85.26%, respectively, 7-28 days after treatment. C.medinalis and C.suppressalis were obviously controlled by 240 g/L metaflumizone SC and 1% emamectin benzoate ME, and the control efficacies were 76.98%-92.16% and 76.37%-80.98%, 69.29%-83.61% and 68.84%-82.95%, 7-28 d after treatment. Additionally, C. suppressalis and C.medinalis were effectively controlled by 5% flufiprole EC and 30% indoxacarb WG, respectively, but not by 20% triazophos EC, 40% isocarbophos EC, 29% bisultap AC and 240 g/L methoxyfenozide SC. These results suggested that the rational applications of diamides, macrolides antibiotics, spinetoram and metaflumizone could be recommended for controlling C. suppressalis and C.medinalis in rice production. |
