The cactus moth, (Berg) (Lepidoptera: Pyralidae), is an invasive species in North America where it threatens native populations. The insect is expanding its distribution along the United States Gulf Coast. In the search for alternative strategies to reduce its impact, the introduction of a natural enemy, Martínez and Berta (Hymenoptera: Braconidae), is being pursued as a biological control option. To identify promising areas to intentionally introduce for the control of , we estimated the overlap of fundamental ecological niches of the two species to predict their common geographic distributions using the BAM diagram. Models were based on native distributional data for both species, 19 bioclimatic variables, and the Maxent algorithm to calculate the environmental suitability of both species in North America. The environmental suitability of in North America was projected from Florida to Texas (United States) along the Gulf coastal areas, reaching Mexico in northern regions. environmental suitability showed a substantial similarity with the calculations for in the United States. Intentional introductions of in the actual distribution areas of the cactus moth are predicted to be successful; will find its host in an environment conducive to its survival and dispersal.
仙人掌螟（Berg）（鳞翅目：螟蛾科）是北美地区的一种入侵物种，对当地种群构成威胁。这种昆虫正在美国墨西哥湾沿岸扩大其分布范围。为了寻找减少其影响的替代策略，引入天敌马氏啮小蜂（Martínez and Berta）（膜翅目：茧蜂科）作为一种生物防治选择正在进行中。为了确定有意引入马氏啮小蜂以控制仙人掌螟的有前景区域，我们使用BAM图估计了这两个物种基本生态位的重叠情况，以预测它们共同的地理分布。模型基于两个物种的原生分布数据、19个生物气候变量以及Maxent算法，来计算这两个物种在北美的环境适宜性。仙人掌螟在北美的环境适宜性从佛罗里达州沿墨西哥湾沿岸地区一直延伸到得克萨斯州（美国），在北部地区延伸至墨西哥。马氏啮小蜂的环境适宜性与在美国对仙人掌螟的计算结果显示出很大的相似性。预计在仙人掌螟实际分布区域有意引入马氏啮小蜂将会成功；马氏啮小蜂将在有利于其生存和扩散的环境中找到其寄主。
