Those tests were of 20-70 kHz, not 45-67 Hz. I've found no peer-reviewed tests of low frequency sound, but then I don't know where to look. Got any ideas? (I do see another study on NIH showing high frequency sound induced increased biting rates ... <a href="http://www.ncbi.nlm.nih.gov/pubmed/20618651" target="_blank">http://www.ncbi.nlm.nih.gov/pubmed/20618651</a> ) </blockquote><div> James, You are quite right, I did not pay close enough attention to the units (Hz vs kHz) , but at least I provided the citation so I could be challenged :-) I was a GenBank Fellow at the NIH National Library of Medicine, so PubMed is my go-to database fo biomedical publications, there are others that might be checked (e.g. Agricola for agriculture) , but I suspect that PubMed would have the relevant literature if it existed. It has over 20 million citations from thousands (if not tens of thousands) of journals, including the <a href="http://www.ncbi.nlm.nih.gov/pubmed/2906666#" title="Journal of the American Mosquito Control Association.">J Am Mosq Control Assoc.</a> where I found the citation I provided. As the mosquito is the unofficial state bird of New Jersey, (where I grew up), and NJ mosquitos have been know to carry off small children, I have a natural skepticism of any claims to be able to deter them that are not rigorously tested :-) </div></div> cjl
