摘要
【目的】比较分析大豆-玉米带状复合种植模式及大豆、玉米纯作模式下主要害虫的发生规律,为科学制定害虫防治策略提供参考依据。【方法】2022年7-9月在山东省邹平市,采用性诱方法对大豆-玉米带状复合种植模式和大豆、玉米纯作模式下棉铃虫Helicoverpa armigera、甜菜夜蛾Spodoptera exigua、斜纹夜蛾Spodoptera litura、亚洲玉米螟Ostrinia furnacalis和点蜂缘蝽Riptortus pedestris等主要害虫发生情况进行调查与统计分析。【结果】大豆-玉米带状复合种植区棉铃虫和亚洲玉米螟发生数量显著高于纯作区(P<0.05),点蜂缘蝽数量也高于纯作区,但差异不显著(P>0.05),说明大豆-玉米带状复合种植可促进这3种害虫的发生。斜纹夜蛾在复合种植区的诱集数量低于纯作区,甜菜夜蛾数量低于玉米纯作区而高于大豆纯作区,但差异均不显著(P>0.05)。复合种植区和纯作区棉铃虫、斜纹夜蛾、亚洲玉米螟和点蜂缘蝽的发生趋势与高峰基本相似,但复合种植延后了甜菜夜蛾发生的第2个高峰1-2周。【结论】大豆-玉米带状复合种植较纯作可促进棉铃虫、亚洲玉米螟和点蜂缘蝽的发生,降低斜纹夜蛾的发生,本文结果可用于害虫的预测预报,并为当地实施有效的害虫防控措施提供科学依据。
[Aim]To compare the occurrence of the main pests in intercropped soybean and maize fields to that in soybean or maize monocultures in order to improve pest control strategies.[Methods]Five attractants and traps were set up for five main pest species(Helicoverpa armigera,Spodoptera exigua,Spodoptera litura,Ostrinia furnacalis and Riptortus pedestris)in mixed soybean-maize crops and in soy and maize monocultures.[Results]The number of H.armigera and O.furnacalis trapped in intercropped areas was significantly higher than in monocultures(P<0.05).The number of R.pedestris trapped in intercropped areas was also higher than in monocultures(P>0.05),but not significantly so,which suggests that intercropping soy and maize may promote the occurrence of these three pest species.Fewer S.litura were,however,trapped in intercropped areas than in monocultures.Fewer S.exigua were trapped in maize monocultures than in soybean monocultures,but this difference was not significant(F=0.51,P>0.05).There was no significant difference in the occurrence and peak abundance of H.armigera,S.litura,O.furnacalis and R.pedestris between intercropped areas and monocultures.However,the second occurrence peak of S.exigua occurred 1-2 weeks later in intercropped areas than in monocultures.[Conclusion]Not all pests are effectively controlled by intercropping soybean and maize.These results can be used to predict the occurrence of the next generation of pest larvae,which is useful for the implementation of local prevention and control technology.
