passive box trap modification

passive box trap modification

Researchers in Australia have tested modifications to two common types of mosquito traps to allow mosquito excreta, or liquid waste droplets, to be collected for virus detection. A schematic view (A), outside view of a trap in field deployment (B) and inside view of a trap with its lid removed (C) show how passive box traps were modified: (a) feeding substance fixed with a magnet, (b) specimen jar holding a sponge, (c) a rope covered with plastic tubing to transfer water to the sponge, (d) bottle filled with water, (e) mesh preventing dead mosquitoes falling into the waste collection insert, and (f) an insert with nucleic acid preservation cards, which can preserve viral RNA at room temperature for later testing.
