To successfully suppress or eliminate a colony, termites must remain at baited sites long enough to transfer the toxicant from the station to cohorts. Other studies have reported on proper placement of stations to increase the probability of termite attacks and to reduce the time required for termites to initially locate monitoring stations (Henderson et al. 1998; Jones 2003). Henderson et al. (1998) reported that termites attack monitors twice as often when placed in conducive locations rather than in a random pattern. Jones reported an average 38-day decrease in time to termite attack when monitoring stations were targeted rather than random.

Early detection is vital in order to prevent outbreaks and financial losses due to the costs associated with pest control services and replacement of infested items. If bed bug chemical attractants could be determined, an effective monitoring and trapping device could be designed. The objective of this study was to identify those chemicals that are attractants to Cimex lectularius. Potential chemical attractants were selected from a chemical analysis of an area heavily infested with bed bugs and from the headspace of bed bug infested culture jars, as well as, an extensive literature search selecting known attractants to hematophagous arthropods. Seventy eight chemicals were tested for attractiveness at a concentration of 1%. Chemicals identified from culture jars were tested at 1%, 10%, and 100% concentrations. A Y-tube olfactometer was used to test each chemical against a control. The str...

One protein residue, nitrophorin, present in the saliva of bed bugs, has been detected from wipes of infested surfaces where bed bugs harbor. Additional proteins have yet to be identified. Dow AgroSciences has successfully developed antibodies unique to bed bug specific antigens. Use of these antibodies has shown antigen-antibody reaction from surface wipes taken from bedbug infested harborages. Sensitivity of the results appears to be a function of the intensity of the bed bug infestation (i.e., high populations yield positive results, low populations yield no detectable results). Studies showed that bed bugs deposit protein residues on infested surfaces. The antibody analysis demonstrated the detection of specific immune reactive proteins derived from bed bugs, although the identity of these proteins has not been determined. Mass spectrometr...
