中文摘要：
【目的】 网蝽科Tingidae
害虫严重危害我国农林经济作物，盲蝽科Miridae昆虫作为该虫的主要天敌类群之一，对网蝽害虫的绿色防控具重要意义。为明确军配盲蝽Stethoconus
japonicus（Schumacher）雌、雄成虫对5种重要网蝽害虫的控害潜能，评价其生防潜力。【方法】 在恒定条件（温度（26±1）℃，相对湿度70%±5%，L︰D=14︰10）下研究了军配盲蝽雌、雄成虫对茶网蝽Stephanitis chinensis（Drake）、梨网蝽S. nashi（Esaki
et Takeya）、桂花网蝽Eteoneus sigillatus（Drake et Poor）、入侵害虫菊方翅网蝽Corythucha marmorata（Uhler）和悬铃木方翅网蝽C. ciliate（Say）成虫的捕食选择性及捕食作用。【结果】 军配盲蝽雌、雄虫对5种网蝽捕食选择率大小依次为茶网蝽>悬铃木方翅网蝽>梨网蝽>菊方翅网蝽>桂花网蝽，且雌虫比雄虫选择偏好性更强；军配盲蝽对5种网蝽的平均捕食量存在显著性差异，雌虫较雄虫平均捕食量大；军配盲蝽雌、雄虫对5种网蝽的捕食功能反应均符合Holling Ⅱ型，对茶网蝽捕食效能a¢/Th最高，最大日捕食量1/Th，分别为36.2和28.6头，其次为悬铃木方翅网蝽，而对桂花网蝽捕食效能最低，最大日捕食25.4和18.7头。【结论】 军配盲蝽成虫对5种网蝽均具有较好的控害潜能，对茶网蝽和入侵害虫悬铃木方翅网蝽有较强的选择偏好性和捕食效能，研究为准确评价军配盲蝽捕食网蝽的生防潜能提供了理论依据。
英文摘要：
[Objectives] To evaluate the potential for male and female Stethoconus japonicus Schumacher (Miridae) to be used as a biological control for 5 species of Tingidae, which are important pests of commercial agricultural and forestry crops in China. The Miridae are natural predators of the Tingidae that could potentially play an important role in the environmentally-friendly control of the pests.【Methods】 The prey preferences and predatory function of adult S. japonicaswith respect to Stephanitis chinensis, S. nashi, Corythucha ciliata and C. marmorata were measured under constant environmental conditions (26±1)℃, 70%±5% RH.【Results】 The relative preference of female and male S. japonicas for the five Tingid species was, S. chinensis>C. ciliate>S. nashi>C. Marmorata. Females had stronger prey preferences than males. There was a significant difference in the average number of each of the 5 species of Tingidae preyed on by S. japonicas. The average number of prey consumed by females was greater than that consumed by males. Predation by S. japonicas on the five Tingid species approximated a Type II Holling functional response. The predatory efficiency (a¢/Th) of S. japonicas was highest when preying on S. chinensis, followed by C. ciliate. The maximum daily predation rate (1/Th) of females and males on S. chinensis was 36.23 and 28.57 individuals, respectively. The lowest predatory efficiency was on E. sigillatus for which the maximum daily predation by females and males was 25.38 and 18.66 individuals, respectively.【Conclusion】 Adult S. japonicus have the potential to be an effective biological control for all five Tingid species tested but are most effective at controlling S. chinensis and C. ciliata. The results of this study provide a theoretical basis for the evaluating the potential of S. chinensis as a biological control for the Tingidae.
