| Abstract: | In 2015-2017, the densities and dynamics of lacewings on 17 common weeds around cotton fields were systematically investigated using a sweeping method in the northern Xinjiang cotton-growing region. The results indicated there were six lacewing species in weed strips of northern Xinjiang, with the dominant species of Chrysopa carnea (64.8%) and Chrysopa phyllochroma (25.8%). The density of lacewings varied significantly on different weeds. Medicago sativa and Cannabis sativa harbored significantly higher lacewing densities among all weed species in 2015 and 2016, respectively. Higher densities of lacewings were found on Glycyrrhiza uralensis, Apocynum venetum, Sophora alopecuroides in 2017. Besides, obvious seasonal fluctuation of lacewing density was also observed. The density of lacewings during flowering and boll-opening stages of cotton (July-September) was significantly higher than that in cotton seedling and bud stages (May-June). This study clarified population composition, densities, and dynamics of lacewings on various weeds adjacent to cotton fields in northern Xinjiang. M. sativa, C. sativa, G. uralensis, A. venetum, and S. alopecuroides were proved to have the potential as functional plants for lacewing conservation. These results provide a scientific basis to promote the conservation and biological control service of predatory lacewings. |
