摘要
室内用叶片药膜法测定了9种杀虫剂对双斑萤叶甲成虫的毒力。结果表明,氟虫腈、噻虫嗪、硫丹、啶虫脒、吡虫啉、棉铃虫核型多角体病毒6种杀虫剂对该虫有较高的毒性,LC50分别为0.3593、1.9896、3.3681、7.4012、8.906mg/L和1.31×108PIB/L。田间试验表明,制剂用量5%氟虫腈SC112.5g/hm2、25%噻虫嗪WG225.0g/hm2及生物制剂棉铃虫核型多角体病毒450.0g/hm2都具有很好的防治效果,且前两种药剂持效期长,药后7d防效在90%以上。
The toxicity of nine pesticides to adult of Monolepta hieroglyphica were determined in room by leaf-dip method. The results showed that fipronil, thiamethoxam, endosulfan, acetamiprid, imidacloprid and NPV had higher activities, their LC50 were 0.3593, 1.9896, 3.3681, 7.4012, 8.906 mg/L and 1.31 × 10^8 PIB/L, respectively. The results of field trial showed that 5% fipronil SC 112.5 g/ha, 25% thiamethoxam WG 225.0 g/ha and NPV 450.0 g/ha had better control effects, and 5% fipronil SC, 25% thiamethoxam WG had longer persistence against the insect, their controlling efficiency exceeded 90% after 7 days.
