Insecticide Resistance of Cimex lectularius L. Populations and the Performance of Selected Neonicotinoid-Pyrethroid Mixture Sprays and an Inorganic Dust
Round 1
Reviewer 1 Report
1. Could you explain in your materials and method to suggest why only males were included in the experiment?
2. Why do you choose these 3 particulars insecticide formulations (Transport, Tandem, and Temprid) as your testing subjects? There are also other insecticide formulations that were labelled for bed bug treatment, for instance a few formulations from Sumitomo Chemical.
3. Could you explain why did you use 10x of LD99 as your discrminating dosage? Noticed that you compared the validity of using 10x by conducting another set of experiment with 5x. Why not using the LD90 as the discriminating dose? As there might be a risk of masking the actual resistance level or underestimate the resistance status of a population when using higher discriminating dosage.
4. Noticed that you include both RR50 and RR90 in your results. I do noticed that there is a few populations that exhibited large differences between RR50 and RR90. What do you think causes the differences? Could you include a few sentences in your manuscript to explain which of it do you think is more suitable to represent the resistance status of a population?
