A pentane extract of flowers common milkweed, Asclepias syriaca (Asclepiadaceae), elicited significant orientation from both male and female Culex pipiens in a dual-port flight olfactometer. Analysis the by gas chromatography-mass spectrometry revealed six major constituents order relative abundance: benzaldehyde, (E)-β-ocimene, phenylacetaldehyde, benzyl alcohol, nonanal, (E)-2-nonenal. Although not all were collected headspace profile live flowers, synthetic blend these compounds, when...
Abstract Understanding how life is adapting to urban environments represents an important challenge in evolutionary biology. Here we investigate a widely cited example of adaptation, Culex pipiens form molestus , also known as the London Underground Mosquito. Population genomic analysis ∼350 contemporary and historical samples counter popular hypothesis that originated belowground less than 200 years ago. Instead, show first adapted human aboveground Middle East over course >1000 years,...
Knowledge of the link between a vector population's pathogen-transmission potential and its biotic environment can generate more realistic forecasts disease risk due to environmental change. It also promote effective control by both conventional novel means.This study assessed effect particular plant species assemblages differing in nectar production on components vectorial capacity mosquito
ABSTRACT Parthenin and parthenolide are natural products that closely related in structure to artemisinin, which is also a sesquiterpene lactone (SQL) one of the most important antimalarial drugs available. Parthenin, like has an effect on Plasmodium blood stage development. We extended evaluation parthenin as potential therapeutic for transmissible stages falciparum it transitions between human mosquito, with aim gaining mechanistic insight into inhibitory activity this compound. posited if...
Mosquito eggs laid on water surfaces typically hatch spontaneously soon after the embryos within them become fully formed first-instar larvae. However, we have found that Anopheles gambiae Giles, an important vector of malaria in Africa, exhibits delayed hatching until surface is agitated, a feature overlooked most laboratory colonies. Agitation 24 h postoviposition, before embryonation was complete, failed to stimulate postembryonic isolated following day (day 2), when < 1% had hatched...
Modulation of odorant receptors mRNA induced by prolonged odor exposure is highly correlated with ligand-receptor interactions in Drosophila as well mammals the Muridae family. If this response feature conserved other organisms, presents an intriguing initial screening tool when searching for novel receptor-ligand species predominantly orphan olfactory receptors. We demonstrate that modulation to 1-octen-3-ol occurs a time- and concentration-dependent manner Aedes aegypti mosquitoes. To...
Abstract Cantharidin is produced by blister beetles (Coleoptera: Meloidae) and smaller oedemerid (Coleopetra: Oedemeridae) found in hemolymph various tissues. The function of cantharidin the courtship behaviour meloids had never been fully established. Our studies show a correlation between density cuticular pores titre scape pedicel segments male specimens East African species Epicauta nyassensis (Haag‐Rutenberg, 1880) Meloidae). Light microscopy semi‐thin cross sections indicates that...

Aedes aegypti (L.) and albopictus (Skuse) mosquitoes of both sexes were attracted to a 3-part volatile synthetic phytochemical blend but differed according their component ratios, 7:3:2 or 1:1:1, initial concentrations. These arbovirus vectors presented with the blends as baits in paired baited blank CFG traps large greenhouse mesocosm. Ae. attraction was highest at ratio, concentration half that found most effective for an anopheline mosquito species outdoor screenhouses. Both lower higher...
