“…Lutzomyia shannoni (Dyar), the most anthropophilic species in the United States (Young and Perkins 1984), is no exception. Recent detection surveys have expanded the known range of this species northward by several hundred kilometers (Haddow et al 2008, Minter et al 2009) and other studies have revealed some information regarding temporal activity and trap capture of L. shannoni (Brinson et al 1992, Comer et al 1994, Minter et al 2009, Mann et al 2009, Minter 2010, Mann and Kaufmann 2010, Minter and Brown 2010.…”

Sand flies are small blood feeding dipterans that are primary vectors of numerous human and livestock pathogens. Control efforts are often complex and multidimensional. A fundamental step in the development and implementation of any integrated pest management (IPM) program is the refining of effective surveillance and identification techniques. Before this study, the presence of two species, Lutzomyia shannoni (Dyar) and Lutzomyia vexator (Coquillett) became known in Kentucky and surrounding states. To understand the spatial distribution of these species across heterogeneous landscapes in this region, trapping was conducted at random locations in previously designated habitats. Although a lack of clear data prevented any conclusions to be drawn for the preferences of L. vexator, the species of greater medical and veterinary importance, L. shannoni, was documented to show a strong preference for habitats along the wooded edges of pasture lands. In the region of study, these lands are frequently used in the production of beef cattle and other livestock, reinforcing the veterinary significance of the findings. Because of their familiarity to vector control officials and operators, mosquito species compositions were compared with the recorded abundance of L. shannoni across the varied habitats. The linking of this information should prove useful to management plans for the phlebotomine, if warranted in the future.

“…Although information on natural history and trapping that could be useful in surveillance has improved (Comer and Brown, 1993;Brinson et al 1992;Comer et al , 1994Haddow et al 2008;Claborn et al 2008;, Mann et al 2009Minter et al 2009Minter et al , 2011Minter 2010;Mann and Kaufmann 2010;Minter and Brown 2010), identiÞcation remains troublesome across this group of insects. Current taxonomic keys to the Phlebotominae are difÞcult to use and are largely based on features of the genitalia and internal reproductive structures, which require the use of tedious clearing, dissection techniques and microscopy, or both (Young and Perkins 1984, Young and Duncan 1994, El-Hossary 2006.…”

Molecular Identification of Sand Flies (Diptera: Psychodidae) in Eastern North America by Using PCR-RFLP

Sand flies (Diptera: Psychodidae) are small blood-feeding dipterans that are primary vectors of numerous human and livestock pathogens. Effective surveillance programs with accurate identification tools are critical in development and implementation of modern integrated pest management programs. Although morphological keys are available for North American species, identification can still be challenging owing to the nature of sample preparation and incompatibility with molecular or biochemical-based pathology assays. Further, the potential for introduction of Old World or other exotic species is not accounted for by current keys. Herein, we present the development and validation of a restriction fragment-length polymorphism-based molecular identification method. Specifically, cytochrome c oxidase subunit I, a mitochondrial DNA marker, was used to distinguish two species of adult sand flies indigenous to eastern North America with two exotic species not yet known to occur in the United States.

Understanding the biology of blood-feeding arthropods is critical to managing them as vectors of etiological agents. Circadian rhythms act in the regulation of behavioral and physiological aspects such as blood feeding, immunity, and reproduction. However, the impact of sleep on these processes has been largely ignored in blood-feeding arthropods, but recent studies in mosquitoes show that sleep-like states directly impact host landing and blood feeding. Our focus in this review is to discuss the relationship between sleep and circadian rhythms in blood-feeding arthropods along with how unique aspects such as blood gluttony and dormancy can impact sleep-like states. We highlight that sleep-like states are likely to have profound impacts on vector-host interactions but will vary between lineages even though few direct studies have been conducted. A myriad of factors, such as artificial light, could directly impact the time and levels of sleep in blood-feeding arthropods and their roles as vectors. Lastly, we discuss underlying factors that make sleep studies in blood-feeding arthropods difficult and how these can be bypassed. As sleep is a critical factor in the fitness of animal systems, a lack of focus on sleep in blood-feeding arthropods represents a significant oversight in understanding their behavior and its role in pathogen transmission.
