Annotative Bibliographies Taleen Noble Finlayson, C. J., Landry, K. M., & Alyokhin, A. V. (2008). Abundance of native and non- native lady beetles (coleoptera: Coccinellidae) in different habitats in Maine. Annals of the Entomological Society of America, Vol.101, no.6, 1078-1087. doi:10.1603/0013- 8746-101.6.1078 This article studies the possibility that non-native lady beetles may have replaced native lady beetles in some agricultural habitats in Maine, US. Evans (2004) suggested that the native lady beetles retreated to non-agricultural habitats, in reaction to the arrival of non-native lady beetles (habitat compression hypothesis). To test this hypothesis, lady beetles were sampled in a variety of agricultural and non-agricultural habitats. In total, 3,487 and 2,903 lady beetles were collected in 2004 and 2005, respectively. Non-native lady beetles were found in a variety of habitats, including the habitats that would have served as a refuge for native species, if the habitat compression hypothesis was validated. Native species were found in a higher proportion in agricultural habitats compared with non-agricultural habitats. In conclusion, this article refutes the habitat compression hypothesis such that native lady beetles have retreated to non-agricultural habitats in response to the arrival of non-native lady beetles. It can also conclude that this new species did not overpower the current species
