Tenuisvalvae notata (Mulsant) (Coccinellidae) is a predatory ladybird beetle native to South America. It specializes in mealybugs prey (Pseudococcidae), but relatively little is known about its ecology. In contrast, the ladybird beetle Cryptolaemus montrouzieri Mulsant (Coccinellidae) is indigenous to Australia and has been introduced to many countries worldwide including Brazil for biological control of mealybugs. The potential impacts of these introductions to native coccinellids have rarely been considered. The software CLIMEX estimated the climate suitability for both species as reflected in the Ecoclimatic Index (EI). Much of South America, Africa, and Australia can be considered climatically suitable for both species, but in most cases, the climate is considerably more favorable for C. montrouzieri than T. notata, especially in South America. The CLIMEX model also suggests seasonal differences in growth conditions (e.g. rainfall and temperature) that could affect the phenology of both species. These models suggest that few locations in South America would be expected to provide T. notata climatic refugia from C. montrouzieri. Although other ecological factors will also be important, such as prey availability, this analysis suggests a strong potential for displacement of a native coccinellid throughout most of its range as a consequence of the invasion by an alien competitor.

气候适宜性差异表明，南美洲侵入性隐孢子虫可能取代原生的 Tenuisvalvae notata

细叶蠹(Mulsant) (Coccinellidae) 是一种原产于南美洲的掠食性瓢虫甲虫。它专门捕食粉蚧（Pseudococcidae），但对其生态学知之甚少。相比之下，瓢虫甲虫蒙氏隐孢子虫Mulsant (Coccinellidae) 原产于澳大利亚，并已被引入世界许多国家，包括巴西，用于生物防治粉蚧。很少考虑这些引入本地球菌的潜在影响。软件 CLIMEX 估计了这两种物种的气候适宜性，反映在生态气候指数 (EI) 中。南美洲、非洲和澳大利亚的大部分地区可以被认为在气候上适合这两个物种，但在大多数情况下，气候要好得多C. montrouzieri比T. notata，尤其是在南美洲。CLIMEX 模型还表明生长条件（例如降雨和温度）的季节性差异可能会影响这两个物种的物候。这些模型表明，预计南美洲很少有地方可以提供T. notata气候避难所C. montrouzieri. 尽管其他生态因素也很重要，例如猎物的可用性，但该分析表明，由于外来竞争者的入侵，原生瓢虫在其大部分活动范围内具有很大的取代潜力。
