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.
鳄梨螟 Stenoma catenifer Walsingham 的性信息素在检测墨西哥恰帕斯湾安的列斯鳄梨树中的 S. catenifer 雄虫方面具有潜在的应用价值，尽管需要研究影响其有效性的当地参数。在这项研究中，评估了诱捕器类型、诱捕器高度、信息素释放率和信息素活性持续时间，以确定这种信息素在墨西哥恰帕斯湾安的列斯鳄梨树作物田间条件下的有效性。结果表明，使用 Pherocon III（三角洲型）和 Pherocon 1C（翼型）诱捕器捕获的蛾类比使用船型诱捕器捕获的蛾类更多。当诱捕器放置在离地面 4 和 6 米的高度时，捕获 S. catenifer 雄虫的频率高于放置在 2 米高的诱捕器。隔片在最初的 4 周内释放了 85%的信息素，在最初的 3 周内，诱捕的蛾类数量没有差异，只有在第 4 周和第 2 周之间有差异。我们的结果表明，安的列斯鳄梨中的信息素效率取决于诱捕器的放置高度和类型以及信息素隔片的使用时间。
