Bottle Bioassay

Scoring data

Data is recorded at ten minute intervals. The first count should be made as soon as the mesquites are in the bottle.

Run four replicates of each insecticide plus one control (view sample run).


Mosquitoes are scored as alive or dead. It helps to gently rotate the bottle while counting.
