我们研究了雌性螳螂的配偶吸引力，Tenodera aridifolia sinensis，测试诚实的信号与欺骗性的信号，以吸引男性的性食人。我们通过实验改变女性的饮食和交配历史，并测量了一个野生种群的男性笼中女性的吸引力。诚实信号理论预测，处女雌性会以最大的速度吸引雄性，而欺骗性信号理论预测饥饿的雌性（更有可能吃掉雄性）会吸引更多的雄性，特别是在非处女雌性中。我们的研究结果表明，饥饿的女性并没有吸引更多的男性比营养良好的女性。事实上，情况正好相反：饥饿的雌性吸引的雄性要少得多。此外，饥饿的女性并不比营养良好的女性更有可能吸引男性交配后，和交配的女性吸引男性在一个较低的利率比处女女性。我们还观察了雌性T. aridifolia sinensis和雄螳螂religiosa到达笼中的女性，我们讨论了这些观察的意义。这一结果反驳了欺骗性信号的假说，并表明雌性T。aridifolia sinensis是雌性配偶可用性的诚实指标，并且性食同类的风险较低。
We studied mate attraction by females of the praying mantid, Tenodera aridifolia sinensis, testing honest signaling of mate availability versus deceptive signaling to attract males for sexual cannibalism. We experimentally varied female diet and mating history and measured the rate of attraction of a wild population of males to caged females. Honest signaling theory predicts that virgin females will attract males at the greatest rate whereas deceptive signaling predicts that hungry females ( which are more likely to cannibalize males) will attract more males, particularly among non-virgin females. Our results show that hungry females did not attract more males than well-fed females. Indeed, the opposite was true: hungry females attracted significantly fewer males. Moreover, hungry females were no more likely than well-fed females to attract males subsequent to mating, and mated females attracted males at a lower rate than did virgin females. We also observed female T. aridifolia sinensis and male Mantis religiosa arriving at the caged females and we discuss the significance of these observations. The results refute the hypothesis of deceptive signaling and show that mate attraction signals of female T. aridifolia sinensis are honest indicators of female mate availability and a lower risk of sexual cannibalism.
