摘  要：
为了有效防治林木上的星天牛,2010—2012年用4种新烟碱类似物杀虫剂对美国红枫苗圃中植株进行了星天牛的防治试验。结果表明,用20%丁诺特呋喃涂干对星天牛成虫羽化出孔有一定抑制作用;50%噻虫胺、25%噻虫嗪和20%丁诺特呋喃根施虽对星天牛幼虫有一定的毒杀作用,但达不到在苗圃中阻止星天牛传播的目的。各处理中,75%吡虫啉根施对星天牛防治效果最好,2种剂量下(单位胸径有效成分用量0.22 g/cm、0.12 g/cm)施药后1 a防治效果均达100%,连续2 a根施吡虫啉后,第3年在未施药的情况下星天牛成虫的死亡率仍在80%以上,说明利用吡虫啉根施可以有效控制美国红枫苗圃中的星天牛。

摘  要：
To effectively control Anoplophora chinensis on forest plants,four neonicotine derivatives were applied to control A. chinensis in the Acer rubrum nursery from 2010 to 2012. Results showed that coating stem with 20% dinotefuran SG had a certain inhibition effect on A. chinensis eclosion. Root application of50% clothianidin WDG,25% thiamethoxam WG and 20% dinotefuran SG had a certain toxicity effect on A. chinensis larva,but could not reach the target of preventing the spread of A. chinensis in the nursery.Among the several treatments,root application of 75% imidacloprid WP had the best control effect. The control effect of two dosages( active ingredient amount of a DBH unit: 0. 22 g / cm and 0. 12 g / cm) after one year could reach 100%. Inoculation experiment showed that after two consecutive years of root application of imidacloprid,the mortality rate of A. chinensis adult was still over 80% without applying imidacloprid in the third year. It showed that root application of imidacloprid could fully control A.chinensis in the A. rubrum nursery.
