本试验通过2011和2012两年的田间调查,初步研究了棉盲蝽对12个不同棉花品种的选择偏好性及其种群总体发生动态。调查发现,华北地区棉田主要盲蝽种类为中黑盲蝽Adelphocoris suturalis(Jakovlev),2011年中黑盲蝽比较偏好喜食的棉花品种是海7124,而不偏好的品种是N73DeltapineFO,2012年中黑盲蝽比较偏好喜食的棉花品种是苏联棉,而不偏好的品种是荆7516-1。分析中黑盲蝽的种群发生动态发现,中黑盲蝽于每年的6月底7月初开始在棉田出现,7月中下旬在棉田的种群发生数量达到高峰,并于8月底、9月上旬在棉田的种群发生数量达到最低。
In this study, two field surveys in 2011 and 2012 were conducted to study the preference of cotton lacewaters on 12 different cotton cultivars and their population dynamics. The survey found that the main species of Lygus in cotton fields in North China is Adelphocoris suturalis (Jakovlev). In 2011, Nymphalidae prefer to eat the sea is 7121, while the non-preferred varieties are N73DeltapineFO, Lygus preferred to eat cotton varieties are the Soviet Union cotton, but not the preferred species is Jing 7516-1. In the analysis, the population of Apodemus agrarius was found to be dynamic. The Apolygus lucorum began to appear in the cotton field at the end of June and early July each year. The number of the population in the cotton field reached a peak in the middle and late July. At the end of August and early September, The population of the population to a minimum.
