The sugarcane hairy borer, Hyponeuma taltula (Schaus, 1904), attacks the base of sugarcane and causes the death of the apical bud, a symptom known as "dead heart." In recent years, there has been significant infestation in Brazilian sugarcane crops. With the purpose of finding methods for controlling and/or monitoring the pest for the sustainable cultivation of sugarcane, we characterized the mating behavior of H. taltula and confirmed the release of a sex pheromone by this insect. Sexual activity was observed between the second and ninth hour of scotophase, during which female calling caused the onset of male courtship behaviors and increased their frequency. An ethogram was built showing that males perform seven observable steps: (1) wing flapping, (2) walking with wing flapping, (3) flying, (4) flying towards the female, (5) landing near the female and walking around her, (6) attempting copulation, and (7) copulation (mating). Female sex gland extracts also triggered attraction and male courtship behaviors. These results thus confirm that the female abdominal gland produces a sex pheromone and that the presence of this pheromone in the air is needed to initiate the male courtship sequence. The sexual behavior of H. taltula is compatible with control and/or monitoring methods using female sex pheromones.

甘蔗毛Bor虫，性Hy鱼（鳞翅目：Erebidae）的性行为：女性释放的性信息素的证据。

甘蔗毛bore虫Hyponeuma taltula（Schaus，1904）袭击甘蔗的根部并导致顶端芽死亡，这种症状被称为“死心”。近年来，巴西甘蔗作物大量侵染。为了找到控制和/或监测有害生物以进行甘蔗可持续栽培的方法，我们表征了H.taltula的交配行为并确认了该昆虫释放了性信息素。在禁闭期的第二个小时到第九个小时之间观察到性活动，在此期间，女性打电话引起男性求偶行为的发作并增加了他们的频率。建立了一个心电图，表明雄鸟执行了七个可观察到的步骤：（1）拍打翅膀，（2）随拍打翅膀行走，（3）飞行，（4）朝雌鸟飞行，（5）降落在雌性附近并在雌性周围走动；（6）尝试交配；（7）交配（交配）。女性性腺提取物还引发了吸引力和男性求偶行为。因此，这些结果证实了雌性腹腺产生性信息素，并且需要这种信息素在空气中存在以启动雄性求爱序列。tal。H.taltula的性行为与使用女性性信息素的控制和/或监测方法兼容。
