中文摘要：【目的】探究扶桑绵粉蚧Phenacoccus solenopsis性信息素引诱雄虫的化学通讯规律，为开发其性诱剂产品、实现绿色防控提供科学依据。【方法】采用室内活性测定和室外诱捕实验，分别测试不同剂量性信息素对扶桑绵粉蚧雄虫的引诱效果，并比较田间不同诱芯剂量下的诱捕数量。【结果】室内活性测定显示，性信息素剂量为20和40 µg时对雄虫具有极显著的引诱作用（P<0.01）；田间诱捕实验进一步表明，当诱芯剂量为40 µg时，雄虫诱捕量最大。【结论】本研究明确了扶桑绵粉蚧性信息素的有效引诱剂量，为其性诱剂的开发与田间应用提供了重要依据。
英文摘要：[Aim] To investigate the chemical communication mechanism by which the sex pheromones of Phenacoccus solenopsis Tinsley attract males, and thereby provide a scientific basis for developing sex attractants for the environmentally-friendly control of this pest. [Methods] Laboratory bioassays and field trapping experiments were conducted to evaluate the attractiveness of different doses of sex pheromone to male P. solenopsis. The efficacy of various lure doses was also compared under field conditions. [Results] Laboratory bioassays showed that doses of 20 µg and 40 µg were highly attractive to males (P<0.01). Field trapping experiments further demonstrated that most males were captured with a dose of 40 µg. [Conclusion] These results identify the most effective dose of female sex pheromone for trapping male P. solenopsis, thereby providing important evidence for the development and application of sex attractants for this pest.
