Abstract

This study was carried out to determine the persistency and safety of emulsifiable concentrate (EC) and wettable powder (WP) formulations of Tephrosia vogelii and Piper aduncum (1:5) against natural enemies and broccoli leaves (phytotoxic effects) as well as to assess their effectiveness against Crocidolomia pavonana in field. EC and WP formulations were safe to parasitoid Eriborus argenteopilosus and did not cause any phytotoxic effects on broccoli leaves. Persistency of EC and WP formulations were lower than bio-insecticide Bacillus thuringiensis (BT) and sythetic pesticide with active ingredient deltametrin. The mortality of C. pavonana treated with EC and WP formulations reached 100%, while BT and deltametrin only reached 73.33% and 88.33% respectively, at the first day treatment. The effectiveness of extracts were declined sharply at one day after treatment indicating low persistence of formulation. In field, EC and WP formulations suppressed the population of C. pavonana more than 80% compared to control. Both formulations showed better activity compared to synthetic insecticide deltametrin.

混合植物提取物配方在田间条件下防治卷心菜害虫的安全性和有效性

本研究旨在测定五倍子（Tephrosia vogelii）和胡椒（Piper aduncum）乳油（EC）和可湿性粉剂（WP）配方（1:5）对天敌和西兰花叶片的持久性和安全性（植物毒性效应），并评估其在田间对帕沃纳Crocidolomia pavonana的有效性。EC和WP制剂对拟寄生物银毛埃里博尔是安全的，对西兰花叶片没有任何植物毒性作用。EC和WP制剂的持久性低于生物杀虫剂苏云金芽孢杆菌（BT）和含有活性成分溴氰菊素的合成农药。EC和WP制剂处理帕沃纳C.pavonana的死亡率达到100%，而BT和deltametrin在第一天处理时分别仅达到73.33%和88.33%。提取物的有效性在处理后一天急剧下降，表明制剂的持久性低。在田间，与对照相比，EC和WP制剂对帕沃纳C.pavonana种群的抑制率超过80%。与合成杀虫剂溴氰菊素相比，这两种制剂都显示出更好的活性。
