“…For example, compared with the volatile compounds we identified in captive catbirds (Whelan et al, 2010), the chemical profile of free-ranging catbirds includes greater abundance of the carboxylic acids heptanoic, octanoic, and nonanoic, fewer branched carboxylic acids, and the appearance of benzaldehyde. Culex and Aedes mosquitoes (Hwang et al, , 1982Kramer et al, 1980), consistent with an arthropod defensive function. Adult birds had low score plot values and little variation in both PC1 and in PC2, whereas hatch year birds had higher scores for volatile PC1, corresponding to higher levels of pentanoic acid, hexanoic acid, and heptanoic acid.…”

Volatile and Semivolatile Compounds in Gray Catbird Uropygial Secretions Vary with Age and Between Breeding and Wintering Grounds

The uropygial secretions of some bird species contain volatile and semivolatile compounds that are hypothesized to serve as chemical signals. The abundance of secretion components varies with age and season, although these effects have not been investigated in many species. We used solid-phase microextraction headspace sampling and solvent extraction coupled with gas chromatography-mass spectrometry to detect and identify volatile and semivolatile chemical compounds in uropygial secretions of gray catbirds (Dumetella carolinensis). We identified linear and branched saturated carboxylic acids from acetic (C2) through hexacosanoic (C26); linear alcohols from decanol (C10) through docosanol (C22); one aromatic aldehyde; one monounsaturated carboxylic acid; two methyl ketones; and a C28 ester. We tested for the effect of age on signal strength and found that juvenile birds produced greater amounts of volatile C4 through C7 acids and semivolatile C20 through C26 acids, although the variation among individuals was large. Adult birds displayed small concentrations and minimal individual variation among volatile compounds, but produced significantly higher levels of long-chain linear alcohols than juvenile birds. We tested for the effects of season/location by sampling adult catbirds at their Ohio breeding grounds and at their Florida wintering grounds and found that the heaviest carboxylic acids are significantly more abundant in secretions from birds sampled during winter at the Florida site, whereas methyl ketones are more abundant in birds sampled during summer on the Ohio breeding grounds. We observed no effect of sex on semivolatile compounds, but we found a significant effect of sex on levels of carboxylic acids (C4 through C7) for juvenile birds only.

BackgroundThe trend in chemical insecticide development has focused on improving the efficacy against mosquitoes while reducing the environmental impact. Lethal lures apply an “attract-and-kill” strategy that draws the insect to the killing agent rather than bringing the killing agent to the insect.MethodsIn this study, the mosquito oviposition pheromone was extracted from the eggs of Aedes aegypti (L.) and further investigated with a combination of pheromone and granular temephos as a lethal lure.ResultsThe compound caproic acid attracted significantly more egg-laying mosquitos at 1 ppm (660.83 ± 91.61) than the control (343.83 ± 56.24), which consisted of solvent only (Oviposition Activity Index: 0.316). Further investigation of the combination of caproic acid with granular temephos as a lethal lure attracted significantly more gravid female Ae. aegypti to oviposit their eggs than the temephos treated water and control.ConclusionsThis indicated the ability of caproic acid in acting as an attractant and counters the repellency effect of temephos. Additionally, the presence of temephos in the lethal lure also restricted the hatching of the eggs and killed any larvae that hatched.

In addition, 3-methylbutanoic acid is also a component of mosquito oviposition sites, pig manure, and various plant odors, and it was considered a potential kairomone for various insects (Kramer et al 1980, Cossé and Baker 1996, Larsson et al 2003. Our results suggest that the blend of ammonia, L-lactic acid, CO 2 , and 3-methylbutanoic acid (odor D) produces a broad-ranging attractant for many species of nocturnal African mosquitoes.…”

Chemical cues play an important role in the host-seeking behavior of blood-feeding mosquitoes (Diptera: Culicidae). A field study was carried out in The Gambia to investigate the effects of human odor or synthetic odor blends on the attraction of mosquitoes. MM-X traps baited with 16 odor blends to which carbon dioxide (CO 2 ) was added were tested in four sets of experiments. In a second series of experiments, MM-X traps with 14 odor blends without CO 2 were tested. A blend of ammonia and L-lactic acid with or without CO 2 was used as control odor in series 1 and 2, respectively. Centers for Disease Control and Prevention (CDC) traps were placed in a traditional house and an experimental house to monitor mosquito densities during the experiments. The MM-X traps caught a total number of 196,756 mosquitoes, with the most abundant species belonging to the genera Mansonia (70.6%), Anopheles (17.5%), and Culex (11.5%). The most abundant mosquito species caught by the CDC traps (56,290 in total) belonged to the genera Mansonia (59.4%), Anopheles (16.0% An. gambiae s.l. Giles, and 11.3% An. ziemanni Grünberg), and Culex (11.6%). MM-X traps baited with synthetic blends were in many cases more attractive than MM-X traps baited with human odors. Addition of CO 2 to synthetic odors substantially increased the catch of all mosquito species in the MM-X traps. A blend of ammonia + L-lactic acid + CO 2 + 3-methylbutanoic acid was the most attractive odor for most mosquito species. The candidate odor blend shows the potential to enhance trap collections so that traps will provide better surveillance and possible control.Keywords mosquito sampling; odor baits; carbon dioxide; human odor In Africa, major problems are caused by anopheline mosquitoes that act as vectors of human malarias. One of the most important species is Anopheles gambiae s.s. Giles, distinctive for its strong preference for human blood and close association with human habitation.

Gillies and Wilkes (1968) reported that CO 2 could attract mosquitoes to hosts at distances of 18-36 m and skin odors at distances of 54-73 m. Human skin odors were demonstrated to account for most of the attractiveness to An. gambiae (Costantini et al. 1996(Costantini et al. , 1998, whereas breath was shown to be only slightly attractive or even repellent , Mukabana et al. 2004. Evidence has accumulated that the variation of the attractiveness between human individuals to An. gambiae is odor mediated (Brady et al. 1997, Costantini et al. 1998, Mukabana 2002, Qiu et al. 2006b).Although hundreds of componen...
