| 摘 要： | 为了掌握在番茄反季节栽培条件下棉铃虫的发生危害规律,制定无公害防治措施,2004~2005年在贵州大方县达溪镇对番茄棉铃虫发生危害进行了调查及无公害农药防治效果试验。结果表明:棉铃虫幼虫在番茄上危害花、果为8月中下旬和9月下旬~10月中上旬,造成果实虫孔盛期在8月中旬~9月下旬,虫孔高峰9月中旬。选择5种无公害农药做田间防效试验,筛选出3种防效较高的农药,在施药后5 d和10 d,防效分别为93.84%~92.35%、90.86%~84.95%和89.40%~85.20%,可应用于生产。

| Abstract: | The occurrence and damage situation of tomato Helicoverpa armigera and control effects of the pesticide with pollution-free were conducted in Daxi township, Dafang county during 2004 - 2005.. The results show that the flowers and fruits of tomato are damaged by the larvae of Helicoverpa armigera on middle and last ten-day period of August, last ten-day period of September, first and middle ten-day period of October, the full period of insect hole on fruits is from middle ten-day period of August to last ten-day period of September and the peak period of insect hole on fruits is on middle ten-day period of September. Three pesticides with pollution-free and higher control efficiency were selected by the field experiment and their control efficiency were 93.84 % - 92. 35 %, 90. 86% - 84. 95 % and 89.40 % - 85. 20 % respectively, which can be used in tomato production. |
