不同颜色粘虫板对棉田绿盲蝽、中黑盲蝽和赤须盲蝽的诱集效果

为掌握不同颜色粘虫板对绿盲蝽、中黑盲蝽和赤须盲蝽的诱集效果,于2010和2011年的6—10月,用青色、绿色、蓝色、黄色、白色5种颜色粘虫板在山东省棉田内进行诱集试验。结果表明,各粘虫板全年监测中都是6月诱集棉盲蝽数量最多,10月最少,且绿盲蝽的种群数量显著高于中黑盲蝽和赤须盲蝽。不同年份、月份、田块,不同颜色粘虫板的诱集效果不一致,2010年田块1中的绿色、青色和绿色粘虫板诱集的绿盲蝽、中黑盲蝽和赤须盲蝽最多,分别为91.0、2.6、5.8头/板,2011年田块2中的黄色、青色粘虫板诱集的绿盲蝽、中黑盲蝽最多,分别为263.0、3.2头/板,田块1中的白色粘虫板诱集赤须盲蝽最多,为12.4头/板。多因素方差分析结果显示,年份、月份、田块、粘虫板颜色对绿盲蝽和赤须盲蝽的诱集量有显著影响,月份和粘虫板颜色对中黑盲蝽的诱集量有显著影响。通过对2年5块棉田的诱捕效果综合排序,黄色粘虫板诱集绿盲蝽效果相对最好;绿色粘虫板诱集赤须盲蝽效果相对最好;5种颜色粘虫板诱集中黑盲蝽的效果差异不显著。

Trapping effects of different colored sticky cards to mirids Apolygus lucorum, Adelphocoris suturalis and Trigonotylus ruficonis in cotton fields

Cyan, green, blue, yellow and white sticky cards were set in cotton fields in Shandong Province to trap cotton mirids, Apolygus lucorum, Adelphocoris suturalis and Trigonotylus ruficonis from June to October in 2010-2011, which aimed to compare the trapping effects of different colored sticky cards on cotton. The most cotton mirids were trapped in June every year, and the population density of A. lucorum was significantly higher than those of A. suturalis and T. ruficonis. Different colored cards had different trapping effects in different years, months and fields. In 2010, green, cyan and green cards trapped the most of A. lucorum, A. suturalis and T. ruficonis in field 1, with 91.0, 2.6 and 5.8 mirids per card, respectively. In 2011, yellow, cyan cards trapped the most of A. lucorum and A. suturalis in field 2, with 263.0 and 3.2 mirids per card, respectively. White cards trapped the most of T. ruficonis (12.4 per card) in field 1. Multi-way ANOVA analysis showed that trapped numbers of A. lucorum and T. ruficonis were significantly influenced by the year, month, field and card color, while month and card color significantly affected the trapped number of A. suturalis. The ranking analysis based on the trapping results from five cotton fields in two years showed that yellow cards had the best trapping effect on A. lucorum, and green cards exhibited the best trapping effect on T. ruficonis, while there were no significant difference in trapping effects among the five colored sticky cards to A. suturalis.
