摘要
为了安全、有效地控制银杏大蚕蛾(Dictyploca japonica Moore)幼虫对核桃楸的危害,尽量避免防治时污染、破坏生态环境、杀伤天敌、影响人畜健康,采用低毒、无污染、残留低,对人畜安全的生物药剂天然有毒植物提取液等对核桃楸食叶害虫进行室内、外胃毒及触杀防治。白头翁、走马芹10、20、40倍液的校正死亡率分别为95.00%、87.50%、85.00%和100%、93.75%、85.00%;蝙蝠葛10、20倍液和天南星10、20、40倍液的校正死亡率分别为91.25%、82.25%和93.75%、85.00%、80.00%;而豚草、兴安藜芦10、20、40倍液的校正死亡率分别为73.75%、70.00%、57.50%和75.00%、70.00%、65.00%。
Extracts from toxic plants were used as botanical pesticides,with less residue,pollution-free,and low toxicity to people and livestock,to control the leaf-eating pest（Dictyoploca japonica Moore）on Juglans mandshurica both in laboratory and field,aimed to safely and effectively prevent the damage to J.mandshurica.Stomach poisoning and contact toxicity of the pesticides were determined.Results showed that,the corrected mortality rates of the botanical pesticides extracted from Pulsatilla chinensis and Cicuta virosa diluted to 10,20,40 times reached 95.00%,87.50%,85.00% and 100%,93.75%,85.00%;those of botanical pesticides extracted from Menispermum dauricum diluted to 10,20 times and from Arisaema amurense diluted to 10,20,40 times were 91.25%,82.25% and 93.75%,85.00%,80.00%;those of extracts from Ambrosia artemisiifolia and Veratrum dahuricum diluted to 10,20,40 times were 73.75%,70.00%,57.50% and 75.00%,70.00%,65.00%,respectively.
