根据对2011年至2012年三亚市冬季瓜菜豇豆上蓟马的发生为害调查与分析,采取类推法预测,明确了豇豆种植全生育期均可受到蓟马的为害。蓟马发生为害高峰期在豇豆种植后的当年12月至翌年3月初。若遇高温、干旱气候蓟马发生程度将偏重,而遇多雨季节则较轻。可利用五点取样挂蓝板(每点挂5片,规格为25 cm×30 cm)进行监测。当蓝板上诱导的蓟马数量平均达到10头/片时即为田间豇豆蓟马的防治适期,并根据蓟马发生规律总结出豇豆不同生育期绿色防控措施。
According to the investigation and analysis on the occurrence of winter cowpea thrips in winter in Sanya City from 2011 to 2012, the analogy was used to predict the damage of thrips in the whole growth period of cowpea. The incidence of thrips peaked in the cowpea after planting in December the following year to early March the following year. In case of high temperatures, the degree of dry climate thrips will be more emphasis, and in case of rainy season is lighter. Five-point sampling can be used to hang the blue board (each point hanging 5, size 25 cm × 30 cm) for monitoring. When the number of induced thrips on the blue plate reached an average of 10 per tablet, the field control of the cowpea thrips was appropriate. Based on the occurrence of thrips, the green control measures of cowpea at different growth stages were summarized.
