蒙氏隐纹瓢虫Cryptolaemus montrouzieri Mulsant（鞘翅目：瓢虫科）是原产于澳大利亚的一种有效的生物防治剂，目前已被世界各地引种用于粉蚧的防治。虽然成功地使用了超过100年，但在新的地区引入可能会造成环境风险，如果人口成为入侵者。本研究采用群体遗传学方法对黑胸小蠹的入侵潜力进行了预测。montrouzieri。我们的研究结果表明，所有群体之间的遗传多样性水平相似。本地和引进人口之间没有显着的遗传分化，而从本地地区的三个人口显着分歧。引种地的遗传多样性没有降低，说明引种过程中没有出现瓶颈效应。为了避免引进的C. montrouzieri，每个种群的引进记录应明确追踪，应避免从多个来源引进到同一地区。
Cryptolaemus montrouzieri Mulsant (Coleoptera: Coccinellidae) is an effective biological control agent of Australian origin, which has been introduced worldwide to control mealybugs. Although successfully used for > 100 yr, its introduction in a new area may cause environmental risks should the populations become invasive. In the present study, a population genetics method was used to make predictions of the invasive potential of C. montrouzieri. Our results showed a similar level of genetic diversity among all populations. No significant genetic differentiation between native and introduced populations was observed, while three populations from the native region were significantly divergent. The fact that genetic diversity was not reduced in introduced areas suggests that no bottleneck effect has occurred during introduction. To avoid rapid evolution of the introduced C. montrouzieri, the introduction records of each population should be clearly traced and introductions from multiple sources into the same area should be avoided.
