Bedbugs produce enzymes at various stages of their development similar to those known to detoxify pesticides in other insects, so this study looked at the genetics of those enzymes in particular, to see if any were different in resistant bedbugs.  They studied pesticide susceptible and pesticide resistant groups of the insects. The result was a much expanded database of genetic data that will hopefully lead to advanced genetic analysis of both these insects and other blood-drinking insects.<\/p>\n<p>Certain genes, related to anti-pesticide enzymes, were found to be expressed at higher levels in all developmental stages of the pesticide-resistant forms of bedbugs.  This seems to indicate that rather than point-mutation genetic differences, a developmental difference accounts for the ability of some bedbugs to resist pesticide poisoning.<\/p>\n<p><span class=\"Z3988\" title=\"ctx_ver=Z39.88-2004&#038;rft_val_fmt=info%3Aofi%2Ffmt%3Akev%3Amtx%3Ajournal&#038;rft.jtitle=PLoS+ONE&#038;rft_id=info%3A%2F&#038;rfr_id=info%3Asid%2Fresearchblogging.org&#038;rft.atitle=Transcriptomics+of+the+Bed+Bug+%28Cimex+lectularius%29&#038;rft.issn=&#038;rft.date=2011&#038;rft.volume=6&#038;rft.issue=1&#038;rft.spage=&#038;rft.epage=&#038;rft.artnum=&#038;rft.au=Bai%2C+X&#038;rft.au=Et+al.&#038;rfe_dat=bpr3.included=1;bpr3.tags=Biology%2CHealth%2CGenetics%2C+Bedbugs\">Bai, X, &amp; Et al.
