Abstract

We explored how the ratio of blood-feeding behaviour—nonfeeding, bird feeding (ornithophily) and mammal feeding (mammalophily)—and voltinism (univoltine and multivoltine) vary over a latitudinal gradient from Alaska to Florida. These two fixed species traits were divided into five mutually exclusive combinations of trait states—nonfeeding/univoltine, ornithophilic/univoltine, mammalophilic/univoltine, ornithophilic/multivoltine and mammalophilic/multivoltine—within each of three datasets (north, east and west). We found a significant association between location (north, east and west) and trait state, which was driven by the large percentage of nonfeeding females in the north. When this trait state was removed, no significant differences were found for the remaining trait states and locations. Although the distribution of trait states did not differ between east and west datasets, the distribution with relation to 1° changes in latitude within each of these datasets showed distinct differences. In the east, both ornithophilic/univoltine and mammalophilic/univoltine species significantly increased with latitude, in proportion to the total species present. In contrast, the proportion of mammalophilic/multivoltine species decreased as latitude increased. Ornithophilic/multivoltine species in the east and the trait states in the west did not show any significant relationship to latitude.

墨西哥以北北美纬度梯度上黑蝇(双翅目:蚋科)采血和伏蝇的比例变化。
我们探讨了在从阿拉斯加到佛罗里达的纬度梯度上,鸟类的嗜血行为(不嗜血)、鸟类的嗜血行为(嗜鸟)和哺乳动物的嗜血行为(嗜哺乳动物)与伏食行为(单伏食和多伏食)的比例是如何变化的。这两种固定的物种性状在三个数据集(北部、东部和西部)中被分为五种相互排斥的性状组合--不取食/单伏特、嗜鸟/单伏特、嗜哺乳/单伏特、嗜鸟/多伏特和嗜哺乳/多伏特。我们发现,地点(北部、东部和西部)与性状状态之间存在明显的关联,这是由于北部非进食雌性的比例较大。剔除这一性状状态后,其余性状状态和地点均无显著差异。尽管东西部数据集之间的性状分布没有差异,但与纬度变化 1°相关的分布在每个数据集中都表现出明显的不同。在东部,嗜鸟类/嗜非鸟类物种和嗜哺乳类/嗜非哺乳类物种在总物种中所占比例均随纬度的变化而显著增加。相反,嗜哺乳动物/多伏特物种的比例随着纬度的增加而减少。东部的嗜鸟/多伏物种和西部的特征状态与纬度没有明显关系。

期刊介绍: Medical and Veterinary Entomology is the leading periodical in its field. The Journal covers the biology and control of insects, ticks, mites and other arthropods of medical and veterinary importance. The main strengths of the Journal lie in the fields of: -epidemiology and transmission of vector-borne pathogens changes in vector distribution that have impact on the pathogen transmission- arthropod behaviour and ecology- novel, field evaluated, approaches to biological and chemical control methods- host arthropod interactions. Please note that we do not consider submissions in forensic entomology.
