d-柠檬烯混合油剂对红火蚁的毒力及灭巢效果

d-柠檬烯是从芸香科植物中提取出的一种具有杀虫活性的天然单萜烯类化合物。以d-柠檬烯为有效成分并配以食品级植物油制成的80%、85%和90%d-柠檬烯混合油剂对红火蚁有翅繁殖蚁、工蚁、卵和蛹均具有良好的毒杀作用,其中90%d-柠檬烯混合油剂的效果最理想。各浓度d-柠檬烯混合油剂对红火蚁工蚁的作用时间均远小于有翅繁殖蚁。以单蚁巢处理的方式施用90%d-柠檬烯混合油剂,每蚁巢投放吸收了10m L混合油剂的海绵,药后7d灭巢率达97.44%（±2.56）%,与对照药剂0.1%氟虫腈粉剂灭巢率97.22%（±2.78）%差异不显著。以该方法施用90%d-柠檬烯混合油剂灭杀红火蚁巢效果显著,而且比传统的...

Bibliography:D-limonene is a Rutacea plant-derived monoterpene with pesticide properties. A formulation containing d-limonene（as active ingredient） and edible plant oil was assessed on its efficacy on red imported fire ant（Solenopsis invicta Buren）. The toxicity of mixtures containing 80%,85% and 90% d-limonene on fire ants was evaluated in laboratory. All mixtures demonstrated excellent insecticidal effects on reproductive alates,workers,eggs and pupae of fire ants,and the effect of the mixture containing 90% d-limonene was the best. The time of all mixtures for killing workers was much shorter than that for killing alates. The effect of the mixture containing 90% d-limonene as an individual mound treatment was then evaluated. The mixture was applied by a unique method,that a sponge soaking up 10 m L mixture was immediately put into the core of ant mound after rapidly poking a Φ 3 cm hole intothe mound with an iron bar. 97.44（±2.56）% ant mounds on average were dead after application for 7 d,which was not statistically di
