摘　　要：分析了锐丹、锐劲特、辛硫磷 3种杀虫剂对茄二十八星瓢虫的防治效果。结果表明 ,锐丹对该虫幼虫、成虫均有良好的防治效果 ,击倒性强且持效期长 ,药后 3d对幼虫、成虫防效高达 71 .79%～ 1 0 0 % ,药后 1 4d对幼虫防效仍为 1 0 0 %。锐劲特对幼虫有较好的防治效果 ,药后 1 4d防效达 86.44%～ 94.0 3 % ,对成虫防效偏低。辛硫磷对幼虫、成虫防效低且持效期短。 3种杀虫剂对茄子生长均无不良影响。Three insecticides, Redan, Regent and Phoxim, were tested on their control efficacy on eggplants Henosepilachna vigintioctopunctata (Fabricius) larva and adult. The results showed that Redan not only had fast and high control efficacy (85.46%～97.98%) 3 days after the treatment on larva and adult but also had long-lasting efficacy on larva(the control efficacy was still 100% 14 days after the treatment); Regent had better control efficacy (86.44%～94.03%) on larva but lower control efficacy on adult 14 days after the treatment. Phoxim had poor control efficacy both on larva and adult and lasted a shorter period. All the three insecticides had no negative influence on the growth of eggplants.
