捕食性盲蝽（Cyrtorhinus lividipennis罗伊特）以沉积在稻田周围的水稻和禾本科植物上的褐飞虱（BPH）卵为食。对C.青翅目昆虫取食禾本科植物的褐飞虱卵会抑制其生长，但这种现象的基本调控机制尚不清楚。在本研究中，HPLC-MS/MS分析表明，6种氨基酸（氨基酸：丙氨酸，精氨酸，丝氨酸，赖氨酸，苏氨酸，和Pro）的浓度显着高于在水稻比5禾本科物种。当C.在黑翅目昆虫中，雷帕霉素（TOR）途径靶基因Rheb、TOR和S6 K的表达量显著低于取食褐飞虱卵的水稻植株的黑翅目昆虫。治疗C.使用雷帕霉素、dsRheb、dsTOR或dsS 6 K的青翅目雌性导致Rheb、TOR和S6 K表达减少，而保幼激素（JH）类似物甲氧普林部分缓解了这些效应。饮食dsTOR治疗显着影响了一些生理参数，并导致受损的捕食能力，繁殖力和人口增长。本研究表明，这六种氨基酸在介导的TOR通路中起重要作用，而TOR通路反过来又调节卵黄原蛋白（Vg）的合成、繁殖和种群增长。青翅类
The predatory mirid bug, Cyrtorhinus lividipennis Reuter, feeds on brown planthopper (BPH) eggs that are deposited on rice and gramineous plants surrounding rice fields. The development and reproduction of C. lividipennis are inhibited by feeding on BPH eggs from gramineous species, and the underlining regulatory mechanism for this phenomenon is unclear. In the present study, HPLC-MS/MS analysis revealed that the concentrations of six amino acids (AAs:Ala, Arg, Ser, Lys, Thr, and Pro) were significantly higher in rice than in five gramineous species. When C. lividipennis fed on gramineous plants with BPH eggs, expression of several genes in the target of rapamycin (TOR) pathway (Rheb, TOR, and S6K) were significantly lower than that in the insects fed on rice plants with BPH eggs. Treatment of C. lividipennis females with rapamycin, dsRheb, dsTOR, or dsS6K caused a decrease in Rheb, TOR, and S6K expression, and these effects were partially rescued by the juvenile hormone (JH) analog, methoprene. Dietary dsTOR treatment significantly influenced a number of physiological parameters and resulted in impaired predatory capacity, fecundity, and population growth. This study indicates that these six AAs play an important role in the mediated-TOR pathway, which in turn regulates vitellogenin (Vg) synthesis, reproduction, and population growth in C. lividipennis.
