I loved writing these posts! It was an indulgence. The last post should have been about Steelman et al., 2008 which I only found late last year — because it shows DDT LC50s for bed bugs from poultry facilities were through the roof. Quote: “High levels of resistance to DDT, effectively acting as 99% exposure, caused only 20% mortality after 96 h of continuous exposure.” This paper is interesting for other reasons too. Full citation and a brief quote in this Temprid post. [The video clip of Dr. John Osmun and others is no longer available.]
