- Dose the bottle with acetone using labeled pipette.
Acetone is used to serve as a vehicle for spreading the insecticide
over the bottle surface.
Use the same amount for each bottle.
- Dose the bottle with prepared insecticide sample.
(See table below for recommended dosages).
Be sure to use a separate pipette to avoid cross contamination
of different insecticide samples.
- Cap each bottle immediately to avoid premature evaporation.
Repeat this process for each insecticide sample.
On a sheet of graph paper, record the amount of insecticide you
used on each bottle. Be sure to label each bottle with the type
and concentration of insecticide it contains.
Dose a final bottle with acetone only to serve as control.
