“…Flagellum of the C. lectularius antenna had a higher capacity to perceive scents of the host than in the other segments (Levin and Anfinogenova 1981). The ablation of the last segment of the antenna in this specie also prevented the reaction to certain concentrations of the alarm pheromone, and stopped the aggregation behaviour (Levinson et al, 1974). In antenna ablation experiments with Podisus maculiventris (Say) (Het.…”

“…Sensilla with characteristics of olfaction were concentrated on the distal end of the terminal segment in Cimex lectularius L. (Hem. Cemicidae) (Levinson et al, 1974). The highest density of sensilla occurred on the second segment of the flagellum in N. viridula (Brézot et al, 1997) and olfactory sensilla were located on the second and third segments in L. lineolaris (Dickens et al, 1995).…”

“…It is interesting to note that DEET scrambled the odor coding process of ORNs in the Dγ sensillum to most human odors, while no significant influence was presented on the C sensillum. Morphologically, Dγ sensilla are close to the short blunted trichoid sensilla, with ORNs expressing ORs, while C sensilla resemble the coeloconic sensilla (Levinson et al, 1974), with ORNs expressing ionotropical receptors (IRs) in D. melanogaster (32). ORs have been proven to detect a number of alcohols, aldehydes, esters and aromatics (Hallem and Carlson, 2006; Carey et al, 2010; Wang et al, 2010), while IRs are known to be responsible for detecting many polar molecules, such as acids and amines (Abuin et al, 2011; Joseph and Carlson, 2015; McBride, 2016).…”

Molecular Basis of N,N-Diethyl-3-Methylbenzamide (DEET) in Repelling the Common Bed Bug, Cimex lectularius

As the most extensively used chemical repellent, N,N-diethyl-3-methylbenzamide (DEET) displayed repellency to a wide range of insects, including the common bed bug, Cimex lectularius. While the neuronal or molecular basis involved in DEET's repellency have been majorly focused on mosquitos and fruit flies, DEET's repellency to the common bed bug is largely unreached. To gain new insights into the cellular and molecular mechanisms in DEET's repellency to the common bed bug, we characterized the neuronal response of bed bugs to DEET, identified the olfactory receptors targeted by DEET and demonstrated the interfering effect of DEET on bed bug's responses to human odorants. High doses of DEET were required for activating the olfactory receptor neurons in the sensilla of bed bugs and at least three DEET-sensitive receptors were functionally deciphered. These DEET-sensitive receptors presented even more sensitive to certain botanical terpenes/terpenoids which also displayed repellency at varying levels for bed bugs. In addition, DEET produced a blocking effect on the neuronal responses of bed bugs to specific human odors and showed inhibitory effect on the function of odorant receptors in responding to certain human odors. Taken together, our results indicate that DEET may function as a stimulus that triggers avoidance behaviors and a molecular “confusant” for interrupting the host odor recognition in the odorant receptors of bed bugs. The receptors that coincidently responded to both synthetic DEET and botanical terpenes/terpenoids suggested that DEET probably target on receptors that originally responded to terpenes/terpenoids. This study gave novel insight into the mechanisms of DEET's repellency to bed bugs and also provided valuable information for developing new reagents for bed bug control.

“…The antennae of bed bugs play a major role in intraspecific communication (LEVINSON et al, 1974). These authors describe two olfactory regions on the terminal antennal segments of both immature and adult bed bugs, and when deprived of these segments the bugs failed to respond to their alarm pheromone and to their assembling scent.…”

Contact application of precocene 2 (6,7-dimethoxy-2,2-dimethylchromene) to inseminated adult female bed bugs inhibited egg maturation and affected egg viability. Third-stage nymphs exposed to 100/ig/cm 2 showed precocious maturation after the moult to the next stage. Nymphs exposed to lower concentrations of precocene exhibited teratism of the antennae, including the reduction of terminal sensillae. This was thought to be responsible for the bugs not assembling.Reduction in the fecundity in adult bugs, and the morphogenetic and teratogenic activity in nymphs was circumstantially related to reduced levels of juvenile hormone, as a result of exposure to precocene.
