Anti-oviposition activities of used sock media against a dengue vector : prospects of eco-friendly control and solutions to pollution
Yearly, huge amounts of sock refuse are discarded into the environment. Socks contain many molecules, and worn ones, which are rich in smell-causing bacteria, have a strong influence on animals’ behaviors.

| Summary: | Yearly, huge amounts of sock refuse are discarded
into the environment. Socks contain many molecules, and
worn ones, which are rich in smell-causing bacteria, have a strong influence on animals’ behaviors. But the impacts of sock odor on the oviposition behavior of dengue vectors are unknown. We assessed whether Aedes albopictus changes its oviposition activity in response to the presence of used socks extract (USEx) in potential breeding grounds, using choice and no-choice bioassays (NCB). When furnished even chances to oviposit in two sites holding USEx and two others containing water (control), Ae. albopictus deposited significantly
less eggs in USEx than in water sites. A similar pattern
of oviposition preference was also observed when there were more oviposition options in water. When there were greater
oviposition opportunities in USEx sites, Ae. albopictus
oviposited preferentially in water. Females laid significantly
more eggs during the NCB involving water than USEx. Also,
significantly more mature eggs were retained by females in
the NCB with USEx than in that with water. These observations
strongly suggest the presence of molecules with either
repellent or deterrent activities against Ae. albopictus females
and provide an impetus to advocate the integration of used
socks in dengue control programs. Such applications could
be a realistic end-of-life recourse to reroute this waste from
landfills |
