[USA], July 28 (ANI): A disease control centre developed an Autocidal
Gravid Ovitrap (AGO trap) that attracts and captures female mosquitoes looking for a site to lay eggs.

pest control tactic requires the colonization and mass-rearing of the target pest species, the induction of sexual sterility in a large fraction of the insects by an appropriate dose of gamma radiation followed by their release into the field on a sustained basis and in sufficient numbers to achieve appropriate sterile to wild insect over-flooding ratios (Knipling 1979).
In this study, we used a modified autocidal
ovitraps predetermined by GIS for surveillance of dengue mosquito vectors to determine high risk areas for dengue disease transmission.
But if larger numbers are required, as in mark-release-capture experiments or in autocidal
control of mosquito populations, the previous approach is merely inappropriate.
In many applications of autocidal
control, it would be efficient to separate the males and females before release (1).
Control--A technique that is used primarily for insect control.
"When I started genetic studies in 1967, I was looking for ways to manipulate the insect's reproduction or its behavior, hoping to make it a candidate for an autocidal
or self-killing control method," says Alan C.
([dagger]) Because conventional vector control approaches often fail to result in effective and sustainable prevention of infection with viruses transmitted by Aedes mosquitoes (5), and to improve surveillance of mosquito population densities, CDC developed an Autocidal
Gravid Ovitrap (AGO) (6) to attract and capture the female Aedes aegypti mosquitoes responsible for transmission of infectious agents to humans (Figure).
control methods (i.e., sterile insect technique (SIT) and [F.sub.1] sterility) represent the best option for preventing further westward spread of C.
In addition, proposed new autocidal
techniques for tephritid control and eradication rely on temperature sensitivity in offspring (Handler 2002, 2004).
