| 摘 要： | 1990年在网室试验研究证实，用硝酸铷2000-4000ppm喷洒寄主标记棉盲蝽，方法简便、结果可靠。1991年分别在河南太康县和南阳市用2000ppm的硫酸铷喷洒棉盲蝽集中越冬区域（200m#+2）大量标记棉盲蝽。结果表明，从铷处理区扩散到棉田的铷标成虫占80%以上，其扩散高峰在5月下旬。对野生寄主区在成虫羽化前进行耕翻处理，附近棉田受害率仅6.8%，未处理区的棉花受害率达33.9%-36%，处理效果为80%左右，该研究结果为棉盲蝽的预测预报和综合治理提供了依据。

| Abstract: | Preliminary test proved that Adelphocoris Saturalis and A. lineolatus could be marked with rubidium (2,000-4,000ppm) in screen house in 1990. Based on the results, rubidium sulphate (Rb_2SO_4) aqueous solution (2,000ppm) was sprayed to weed hosts and cotton plant bugs for the investigation of emigration of cotton plant bugs in Taikang and Nanyang counties, Henan province in the out-cotton-fields in 1991. The results showed that more than 80 percent of the captured adults from weeds to cotton fields were marked with rubidium. The peak of dispersal took place in the late May. Treated weed hosts near cotton fields which had been ploughed up before the emergence of adults, the damage rate of cotton plants were 6.8 percent, where untreated area were 33.9-36 percent. The treating effect was about 80 percent. The results provided bases for forecasting and integrative pest management of cotton plant bugs. |
