“…First, resting collections capture adult mosquitoes from a broad range of physiological states (i.e., host-seeking, blood-engorged, gravid, postovipositional) and thus are not useful for calculating vector indices, which are derived from collections of hostseeking female mosquitoes only (Gujral et al 2007). Second, resting traps predominantly attract mosquito vectors in the genera Culex, Culiseta, and Anopheles (Goodwin 1942, Meyer 1985, Komar et al 1995, Burkett-Cadena etal. 2008), but are ineffective for sampling many genera of nuisance and vector mosquitoes such as Coquilletidia, Psorophora, and Aedes (Gusciora 1971).…”

Commercially available wood-fiber pots used to collect resting mosquitoes were modified to improve sampling efficiency. The modified traps, called the Centers for Disease Control and Prevention resting traps, collected 16.0 and 5.2 times more adult Culex pipiens and Cx. tarsalis than the conventional wood-fiber pots. The resting trap increases the mean number of resting mosquitoes collected per trap-night and is useful for collecting blood-engorged mosquitoes. Keywords Resting mosquitoes; Culex pipiens; Culex tarsalis; resting trapMost mosquito species are typically nocturnal or crepuscular, and remain relatively inactive during daylight hours. Samples of these resting mosquitoes provide effective estimates of mosquito population densities. Similarly, resting mosquito collections provide robust samples of blood-engorged mosquitoes. Tree cavities (Burkett-Cadena et al. 2008), animal burrows (Kay 1983), root masses (Mullen 1971), dense vegetation (Kay 1983), and caves are examples of natural daytime resting places for mosquitoes. Man-made structures such as barns, culverts, and basements, which provide dark, moist, and cool environments, also accommodate resting mosquitoes (Crans 1989). Researchers have taken advantage of the resting behavior of mosquitoes by sampling with artificial structures such as nail kegs (Burbutis and Jobbins 1958), wooden boxes (Gusciora 1971), walk-in red boxes (Meyer 1985), plastic trash cans (Burkett-Cadena et al. 2008), and wood-fiber pots (Komar et al. 1995).Vector control and public health surveillance programs rarely collect resting mosquitoes, for several reasons. First, resting collections capture adult mosquitoes from a broad range of physiological states (i.e., host-seeking, blood-engorged, gravid, postovipositional) and thus are not useful for calculating vector indices, which are derived from collections of hostseeking female mosquitoes only (Gujral et al. 2007). Second, resting traps predominantly attract mosquito vectors in the genera Culex, Culiseta, and Anopheles (Goodwin 1942, Meyer 1985, Komar et al. 1995, Burkett-Cadena etal. 2008), but are ineffective for sampling many genera of nuisance and vector mosquitoes such as Coquilletidia, Psorophora, and Aedes (Gusciora 1971). However, resting collections offer the most efficient source of blood-engorged mosquitoes needed for several research applications, suchasvector and arbovirus ecology studies. HHS Public Access Author Manuscript Author ManuscriptAuthor Manuscript Author ManuscriptIn order to enhance the collection of resting mosquitoes, a novel trap design was devised to combine the advantages of the wood-fiber pot (e.g., low cost and portability) with those of conventional, suction-type traps (few escapees, larger samples). Traditionally, collections from these pots are made daily by aspirating resting mosquitoes from the interior walls of the pots using either a handheld aspirator or a backpack aspirator. However, slight movements can startle resting mosquitoes before they can be aspirated, and changing envi...

“…Field experiments designed to test the relative attractiveness of transmitted light of different wave lengths also yielded negative results for the same reason. The only wave length attraction study found involving A. quadrim'(l,culatus is that by Goodwin (1942) in which the species was offered, in its natural habitat, a series of colored artificial resting boxes. He found that they alighted in the largest numbers in red boxes, although others were freely used.…”

“…melanura to determine host bloodsource. From the development of large resting shelters (Goodwin 1942) to study Anopheles , there have been studies on modifications of resting shelters (such as those by Edman et al 1968, Morris 1981) and on the use of these shelters to collect blood-fed Cs. melanura to determine the host source of blood used by this species and by other mosquito species.…”

Twenty resting shelters were set on the edge of a known Culiseta breeding habitat in four groups of five to support a 4 × 4 Latin square field experiment. Collection times were 0900, 1100, 1300, and 1500 hours and systematically rotated for the order by which each group of five boxes was collected. Mosquitoes were collected from resting shelters by chloroform anesthetization. Collections were identified to species, sex, and physiological status of the females (nonblooded or blood-fed and gravid). More than 77% of the mosquitoes collected were Culiseta melanura (Coquillett). Analyses included means and SE for total collections and shelter-day (number collected per units) and means comparison by t-test and general linear model with Student–Newman–Keuls or least significant differences means tests for replicate, group, time, and interactions of time and group. There were few significant differences among or between shelter-day means but more blood-fed and gravid female Cs. melanura were collected at 1300 hours than any other time. Results confirm the effectiveness of resting shelters in a surveillance program for Cs. melanura, demonstrate the ßexibility of resting shelters as a surveillance tool, and suggest that Cs. melanura will move to more acceptable resting sites during daylight.
