防虫网对豇豆上美洲斑潜蝇及豇豆荚螟的控制效果在95％以上。通过7－9月网内外气象资料系统观察表明，在夏秋高温季节防虫网可明显改善小气候环境，提高豇豆的产量，网内豇豆叶片叶绿素含量比同外高5．66％－34．60％；平均叶面积比网外高77．37％；根系活力比网外高12．96％；百株产量比网外高5．95％；单荚重比同外高20．65％。
Insect net on the cowpea on the American leafminers and cowpea pod borer control effect in more than 95%. Observations by meteorological data system from July to September show that the insect net can significantly improve the microclimate environment and increase the yield of cowpea during summer and autumn high temperature season. The content of chlorophyll in the net cowpea leaves is 5.66% -34.60% higher than that of the outer. The average leaf area was 77.37% higher than that of the net. The root vigor was 12.96% higher than that of the net. The yield of one plant was 5.95% higher than that of the net. The weight of single pod was 20.65% higher than that of the net.
