1.种间的负面相互作用，如资源竞争或生殖干扰，可能导致物种流离失所(物种排斥)。在这里，我们研究了生活史、交配行为和对杀虫剂的适应对组成烟粉虱物种复合体的隐蔽烟粉虱物种排斥的影响。我们在澳大利亚、美国和以色列的中国分别进行了种群笼养实验，观察了一种通常被称为B型的入侵物种与另外三种通常被称为ZHJ1、An和Q.3型的入侵物种之间的物种排斥模式。尽管不同地区的实验条件和物种不同，但我们能够使用包含发育时间、交配行为和抗药性数据的随机模型来预测每个地区观察到的排斥模式。交配行为的种间差异比发育时间的差异是影响物种排斥的一个更重要的因素。具体地说，B的交配能力比其他物种更有效，导致B的种群增长速度更快，以及其他物种的种群增长率降低，从而导致物种排斥。B对杀虫剂产生抗药性的较大能力也有助于在某些情况下排除其他物种。结果表明，综合分析生活史特征、交配行为和对杀虫剂的适应变化的后果，可以为预测烟粉虱入侵后的物种排斥提供一个可靠的框架。
P>1. Negative interspecific interactions, such as resource competition or reproductive interference, can lead to the displacement of species (species exclusion).2. Here, we investigated the effect of life history, mating behaviour and adaptation to insecticides on species exclusion between cryptic whitefly species that make up the Bemisia tabaci species complex. We conducted population cage experiments independently in China, Australia, the United States and Israel to observe patterns of species exclusion between an invasive species commonly referred to as the B biotype and three other species commonly known as biotypes ZHJ1, AN and Q.3. Although experimental conditions and species varied between regions, we were able to predict the observed patterns of exclusion in each region using a stochastic model that incorporated data on development time, mating behaviour and resistance to insecticides.4. Between-species variation in mating behaviour was a more significant factor affecting species exclusion than variation in development time. Specifically, the ability of B to copulate more effectively than other species resulted in a faster rate of population increase for B, as well as a reduced rate of population growth for other species, leading to species exclusion. The greater ability of B to evolve resistance to insecticides also contributed to exclusion of other species in some cases.5. Results indicate that an integrative analysis of the consequences of variation in life-history traits, mating behaviours and adaption to insecticides could provide a robust framework for predicting species exclusion following whitefly invasions.
