A Method for Evaluating Insecticide Efficacy against Bed Bug, Cimex lectularius, Eggs and First Instars

The overall goal of this experiment is to assess the effectiveness of insecticides in killing bed bug eggs and first instars. This method can help answer key questions in the entomology field, such as the effects of toxicological assays on bed bug eggs and small nymphs. The main advantage of this technique is that it is designed for treating a difficult insect life stage with insecticides, particularly the egg stage.

To begin the experiment, pull five to 10 mated well-fed adult female bed bugs from a colony and place the females into a Petri dish with filter paper. Prepare 10 replicates to ensure there will be enough eggs for the insecticide assay. Check the dishes every day to see if the females have laid eggs.
