Copitarsia sp. (Hampson) (Lepidoptera: Noctuidae: Cuculliinae) is a quarantine pest in different countries and affects diverse crops of economic importance in South America. The development of ethological control strategies is an important issue that requires knowing the reproductive behavior of the species involved. Therefore, the aim of this study was to establish the reproductive behavior of Copitarsia uncilata (Burgos & Leiva) and to evaluate the attractiveness of synthetic pheromone compounds under laboratory conditions. Observations of nocturnal reproductive behavior of males and females were performed for 7 days in order to register the courtship, mating, and oviposition time. Once the period of the highest reproductive activity was identified, flight behavior and attraction of virgin males were evaluated in a wind tunnel towards synthetic compounds previously reported as commercial pheromones for Copitarsia species, namely (Z)-tetradec-9-enyl acetate (Z9-14Ac), (Z)-tetradec-9-enol (Z9-14OH), and their mixture (Z9-14Ac + Z9-14OH at 4:1 ratio), in comparison with virgin females and clean air flow. We observed that reproductive behavior occurs during the first third of the scotophase and begins on the second day after adult emergence. Highest proportion of courtship and mating occurs on days 2 and 3 after emergence, and oviposition starts the night immediately after the first mating. Wind tunnel assessments showed that males were highly attracted to calling females compared with the blend of synthetic pheromone compounds, with 89% and 12% of males landing at the source, respectively. Moreover, males also showed a low response to the isolated compounds (Z9-14Ac 14% and Z9-14OH 4%).

Copitarsia uncilata（鳞翅目：夜蛾科）的生殖行为。

Copitarsia sp。（Hampson）（鳞翅目：夜蛾科：Cuculliinae）是不同国家的检疫性有害生物，影响了南美具有重要经济意义的多种作物。制定人类行为控制策略是一个重要问题，需要了解所涉物种的生殖行为。因此，本研究的目的是建立Copitarsia uncilata的生殖行为。（Burgos＆Leiva）并评估合成信息素化合物在实验室条件下的吸引力。为了记录恋爱，交配和排卵时间，对男性和女性的夜间生殖行为进行了7天的观察。一旦确定了最高生殖活动的时期，就在风洞中评估了飞行行为和未成年雄性的吸引力，朝着先前报道为合成的木瓜属商品信息素的合成化合物，即（Z）-十四烷基-9-乙酸乙烯酯（Z 9 -14Ac），（Z）-十四烷基-9-烯醇（Z 9-14OH）及其混合物（Z 9-14Ac + Z与原始女性和干净的气流相比，比例为9：14OH（4：1）。我们观察到生殖行为发生在近视阶段的前三分之一，并在成年后第二天开始。求偶和交配的比例最高，出现在出生后的第2天和第3天，并且在第一次交配后的晚上立即开始排卵。风洞评估显示，与合成信息素化合物的混合物相比，雄性对召唤雌性的吸引力更高，分别有89％和12％的雄性降落在源头。此外，雄性对分离出的化合物（Z 9-14Ac 14％和Z 9-14OH 4％）的响应也很低。
