Autocidal Gravid Ovitrap Mosquito Trap for Control and Surveillance of Mosquitoes
Posted Aug 01 2013 8:00pm
Description of Invention: Mosquitoes are responsible for the transmission of a number of important zoonotic diseases, including dengue fever, malaria, and rift valley fever. The CDC-AGO (Autocidal Gravid Ovitrap) mosquito trap is a device that targets older female mosquitoes looking for a suitable place to lay eggs. This device is 45 centimeters tall with a 10-liter capacity to hold an attractant, such as water and decaying vegetation. The mosquitoes are captured by a nontoxic adhesive and eggs are collected on a hydrogel. The use of the hydrogel instead of a liquid prevents the larvae from hatched mosquito eggs from completing development.
Novel aspects of this technology are the use of non-toxic components and slow to dry hydrogel, as opposed to insecticide. While there are a number of chemical methods for controlling mosquitoes, these chemicals are always subject to the evolution of resistance from the mosquito population and, thus, there is a need for additional non-chemical control methods.
Device for mosquito control
May be useful in regions of the world affected by vector-borne zoonotic diseases, such as dengue fever, malaria, Rift Valley fever or West Nile virus
Many ovitraps are short-lived as insecticide compound degrades over time and/or mosquito population becomes insecticide-resistant
Utilizes a nontoxic adhesive and hydrogel polymer, as opposed to insecticide
In vitro data available
