| 本文在3个类型生境中使用同一剂量茚虫威饵剂处理3个密度红火蚁区域，评价了该饵剂对红火蚁活蚁巢、工蚁的防治效果。结果显示，不同生境中随着处理时间的延长，茚虫威饵剂对低密度、中等密度、高密度红火蚁的防效总体变化动态趋势相近，均为由低到高，并趋于稳定；生境植被越茂盛，该饵剂对红火蚁的防效越低，由低到高以依次为浅草草坪、深草草坪、荒草地；蚁巢密度越大，同一剂量饵剂对蚁巢防效越低，由高到低依次为1-3个/100 m2、4-7个/100 m2、>8个/100 m2。研究结果表明,生境植被、红火蚁密度会对毒饵剂的防效产生明显影响。 |
| 英文摘要: |
| The same dose of indoxacarb bait was used to treat the area with 3 densities of red imported fire ant Solenopsis invicta Buren in 3 habitat types, and the controlling efficacy of the bait on the fire ant live nests and workers was determined in this paper. The results showed that, with the time after treatment prolonged, the dynamic trends of controlling efficacy of indoxacarb bait to the low density, medium and high densities of the fire ants were overall similar in different habitats, and that was from low to high first, and then tended to be stable. The more lush the vegetation, the lower the controlling efficacy of the bait to the fire ants was, and these were from low to high in order of wild grassland, high grass lawn and short grass lawn. As the nest density rose, the controlling efficacy of same dose of the bait to the fire ant nests decreased, and these from high to low were 1-3 nests/100 m2, 4-7 nests/100 m2, and >8 nests/100 m2. The above results revealed that the vegetation and the fire ants density would have a significant impact on the controlling efficacy of poison bait. |
