The sex pheromone of the avocado moth Stenoma catenifer Walsingham has potential use in the detection of S. catenifer males in the Antillean race avocado in Chiapas, Mexico, although the study of local parameters that influence its effectiveness is required. In this study, trap type, trap height, pheromone release rate and duration of pheromone activity were evaluated to determine the effectiveness of this pheromone in field conditions in the Antillean race avocado crops of the coast of Chiapas, Mexico. The results obtained indicate that the capture of moths with the traps Pherocon III (delta type) and Pherocon 1C (wing type) was higher than that with the boat-type traps. The frequency of capture of S. catenifer males was higher when the traps were placed 4 and 6 m above ground level than that when they were 2 m high. The septum releases 85% of the amount of pheromone during the first 4 weeks, and there were no differences between the number of moth captures during the first 3 weeks, only between the fourth and the first 2 weeks. Our results suggest that the efficiency of the pheromone in Antillean race avocado depends on trap placement height and type as well as on the time of use of the pheromone septum.

性激素信息素在鳄梨果园中监测口岸狭窄（鳞翅目：El科）的有效性。

鳄梨蛾Stenoma catenifer Walsingham的性信息素可用于检测墨西哥恰帕斯州安蒂尔良种族鳄梨中的S. catenifer男性，尽管需要研究影响其有效性的局部参数。在这项研究中，对诱捕类型，诱捕高度，信息素释放速率和信息素活性的持续时间进行了评估，以确定该信息素在墨西哥恰帕斯州海岸的安提尔尼族鳄梨作物中的田间条件下的有效性。获得的结果表明，用Pherocon III（三角型）和Pherocon 1C（翼型）捕虫器捕获的飞蛾比使用船型捕虫器捕获的飞蛾更高。链球菌的捕获频率当诱捕器被放置在离地面4和6 m处时，雄性要比它们在2 m高时高。在最初的4周内，隔膜会释放85％的信息素，在最初的3周内，捕虫蛾的数量没有差异，仅在第四周和最初的2周之间。我们的结果表明，信息素在Antillean种族鳄梨中的效率取决于诱集装置的高度和类型以及信息素隔片的使用时间。
