摘要 资源的可用性对昆虫的战斗行为有重要影响，但资源影响的生理机制尚不清楚。一氧化氮 (NO) 是一种气态神经递质，能够直接扩散到细胞中并充当信使。多项研究表明，NO 可能参与调节昆虫的战斗行为。在本研究中，我们研究了不同资源对Velarifictorus aspersus Walker雄性蟋蟀（直翅目：蟋蟀科）战斗行为的影响，并测试了这种影响是否受到NO的调节。我们发现，当有洞穴或雌性可用时，与没有可用资源时相比，雄性蟋蟀的战斗水平和战斗持续时间明显更高，从而表明宝贵资源的存在促使雄性蟋蟀更加积极地战斗。在新的环境中，用NO合酶抑制剂NG-硝基-L-精氨酸甲酯（L-NAME）处理显着提高了雄性蟋蟀的战斗水平和战斗持续时间，并且用L-NAME处理的雄性蟋蟀在与用水处理的雄性蟋蟀的战斗中赢得了更多战斗。然而，当有洞穴或雌性可用时，用 L-NAME 处理不会影响雄性的战斗水平和战斗持续时间，并且用 L-NAME 处理的雄性在与用水处理的雄性相比中失败更多。这些结果表明，在不同的资源条件下，NO对于调节雄性V. aspersus蟋蟀的战斗行为可能有不同的影响。
Abstract The availability of resources can have important effects on the fighting behaviors of insects, but the physiological mechanism that might underlie the effect of resources is unclear. Nitric oxide (NO) is a gaseous neurotransmitter that is capable of directly diffusing into cells and acting as a messenger. Several studies have reported that NO may be involved in modulating the fighting behavior of insects. In the present study, we investigated the effect of different resources on the fighting behavior of Velarifictorus aspersus Walker male crickets (Orthoptera: Gryllidae), and tested whether this effect is regulated by NO. We found that when a burrow or female was available, the fighting level and fighting duration were significantly greater in males compared with those when no resources were available, thereby suggesting that the presence of a valuable resource motivated male crickets to fight more aggressively. In a novel environment, treatment with an NO synthase inhibitor NG-nitro-L-arginine methyl ester (L-NAME) significantly increased the fighting level and fighting duration in male crickets, and males treated with L-NAME won more fights against males treated with water. However, when a burrow or female was available, treatment with L-NAME did not affect the fighting level and fighting duration in males, and males treated with L-NAME lost more fights against males treated with water. These results suggest that NO may have different effects on modulating the fighting behavior of male V. aspersus crickets under different resource conditions.
