“…Both studies indicate that during the early scotophase bed bugs remain in their refuges and are aggregated, which supports the results of the present study as during the early scotophase bed bugs were most attracted to putative aggregation cues. As for bed bugs, triatomine bugs (Triatominae: Reduviidae) also show temporal variation of certain activities and a daily rhythm of aggregation has been reported for Triatoma infestans (Minoli et al, 2007). The study identified the presence of a 24h cycle with maximum aggregation at the end of the scotophase and increasing dispersal during the photophase (Minoli et al, 2007).…”

SUMMARYThe common bed bug, Cimex lectularius, feeds on the blood of mammal and bird hosts, and is a pest of global importance. Semiochemicals are chemicals involved in animal communication that may affect behaviour and/or physiology. Attractive semiochemicals that play a role in mediating bed bug behaviour could be exploited for the development of a highly effective novel monitoring device. Tracking software was used to record the response of bed bugs to volatiles from paper previously exposed to conspecific bugs in a still-air olfactometer illuminated by infrared lights, through a variety of activity variables. The effect of time of day as an extrinsic factor, and sex, stage, mating status and nutritional status as physiological factors on the response of bed bugs to the volatiles was examined. Bed bugs of both sexes and all stages responded to the volatiles from bed bug-exposed papers, showing significant attraction and orientation towards the volatile source whether they were starved or engorged. Confirmation that the physiological factors examined do not affect the response of bed bugs to the volatiles from bed bugexposed papers provides evidence that these bed bug-derived volatiles contain aggregation cues, as semiochemicals that promote aggregation should by definition be detected by both sexes and all life stages. A device baited with such semiochemicals could play a major role in limiting the impact of the current bed bug resurgence by enabling timely detection of infestations, along with quantitative evaluation of control and effective surveillance of the geographical distribution of the pest species.

“…While there is to our knowledge, no study examining circadian hunting behaviour in reduviids, circadian patterns are present in the aggregation behaviour of the hematophagous reduviid, Triatoma infestans ( Minoli et al , 2007 ). This may result from some S. bituberus responding later than others, such that more associated with draglines as the day advanced.…”

1. Animals, as they move through their environment, leave traces of their passage that can be informative to others and convey significant advantages to the animal producing them. However, such traces may also reveal presence, location or identity to enemies.2. We studied an araneophagic ('spider-eating') assassin bug, Stenolemus bituberus (Heteroptera, Reduviidae), testing whether it associated with areas containing chemotactile traces (e.g. draglines, excreta) left behind by nine sympatric spider species. Stenolemus bituberus were presented with a choice between a substrate containing draglines and a clean substrate. Each hour, for a duration of 12 h, we recorded which substrate was occupied.3. Stenolemus bituberus tended to associate especially with draglines left by spiders from the genus Achaearanea , their most common prey in nature.4. These results suggest that S. bituberus exploits draglines from these spiders as cues for indicating prey presence. We also found an increasing tendency to associate with draglines from some spider species through the day, which may be related to circadian patterns or slower response times of some individuals.

“…However, the oscillators controlling these rhythms has not yet been studied. 32 Under DD conditions, GPDH-1 flight muscles of T. infestans showed a rhythmic pattern of transcription synchronous with a rhythmic profile of activity, which also suggests regulation by the endogenous circadian clock. We hypothesize that light would have a direct action in suppressing rhythmic gene expression.…”

“…Individuals of this species leave their refuges at the beginning of the night and display the major part of their activities, such as host search, feeding, and dispersion, in discrete temporal windows during this dark period. 32 Thus, this insect stays naturally in the dark during the day. The GPDH-1 isoform, which is involved in flight energetic metabolism, showed a synchronous expression in the DD group that would reflect the living condition of T. infestans.…”

Abstract. Triatoma infestans, the main vector of Chagas disease, is a blood-sucking insect. Flight dispersal of adults is the most important mechanism for reinfestation of houses after insecticide spraying. Flight muscles have two glycerol-3-phosphate dehydrogenase (GPDH) isoforms: GPDH-1 is involved in flight metabolism and GPDH-2 provides lipid precursors. In this study, we explored the profile of GPDH expression in females and males adult flight muscles under light/dark cycle, constant light, and constant dark conditions. Under constant dark conditions, GPDH-1 flight muscles of T. infestans showed a rhythmic pattern of transcription synchronous with a rhythmic profile of activity suggesting regulation by the endogenous circadian clock. Otherwise, the GPDH-2 expression analysis showed no regulation by the endogenous clock, but showed that an external factor, such as the dark/light period, was necessary for synchronization of GPDH-2 transcription and activity.
