“…In the current study, oriental fruit moth females preferred oviposition sites culminating at a temperature of ϳ30ЊC as was clearly shown when the data from the temperature gradient were plotted relative to the area of the different temperature zones in analogy to a recent study by Kü hrt et al (2006). This behavior parallels the preference for a distinct temperature range within a gradient reported for different hematophagous hemipterans (Pires et al 2002, Guarneri et al 2003, Schilman and Lazzari 2004 and for a detrivorous dipteran species (Fogleman 1979). However, in a lepidopteran species closely related to the oriental fruit moth, the codling moth C. pomonella, females preferred the highest available temperature for oviposition regardless of the temperature ranges offered in a similar trial set-up (Kü hrt et al 2006).…”

Oviposition site selection is crucial for the reproductive success of a herbivore insect species with relatively sedentary larvae. The optimal oviposition theory, i.e., the preference-performance hypothesis, has thus far mainly been tested with a focus on nutritional quality of the host. This study investigates whether female oriental fruit moth Grapholita (Cydia) molesta choose a microhabitat for oviposition characterized by a temperature range within which their offspring perform best. Thermal preferences of females during oviposition were assessed in a circular temperature gradient arena. Offspring performance and survival were assessed under different constant temperature conditions. Females preferred oviposition sites of ϳ30ЊC over lower and higher temperatures. At this temperature, egg, larval, and pupal development was signiÞcantly faster than at 22 and 25ЊC, and larval development was also faster than at 33ЊC. At 30ЊC and at the lower temperatures tested, survival of eggs and larvae was signiÞcantly higher than at 33ЊC, whereas development was precluded at 35ЊC. Furthermore, female pupal weight attained at 30 and 33ЊC exceeded that reached at the lower temperatures tested. Considering the potentially reduced predation risk caused by the shorter developmental time of eggs and larvae, the laboratory data suggest that this species maximizes its Þtness by selecting a thermally optimal environment for its offspring, supporting the optimal oviposition theory. Conversely, it is known that the codling moth (C. pomonella) lacks a mechanism to avoid temperatures lethal to progeny development, which may reßect the differences in geographic ranges of these tortricids.

“…In Triatoma infestans and T. brasiliensis, daily temperature preferences vary across a broad range (23) (25) , while in Panstrongylus megistus and R. prolixus, the range of daily temperature preferences varies only slightly (24) (27) . Lower temperature preferences in triatomines during the photophase and with increasing starvation would avoid unnecessary waste of water and nutrients (24) .…”

Introduction: Behavioral fever is a response to infections with microorganisms observed in some poikilothermic animals. Rhodnius prolixus is involved in the transmission of two parasites: Trypanosoma cruzi (pathogenic for humans and transmitted in feces) and Trypanosoma rangeli (non-pathogenic for humans, pathogenic for Rhodnius and transmitted by the bite of an infected individual). Only T. rangeli is found in the hemolymph of Rhodnius as it travels to the salivary glands. Methods: To study vector-parasite interactions, we evaluated possible behavioral fever responses of R. prolixus to intracoelomic inoculation with T. cruzi or T. rangeli. Temperature preferences of fi fth-instar nymphs of R. prolixus were evaluated after inoculation with T. rangeli KP1(+), KP1(-), T. cruzi I, or the Trypanosome culture medium. Four different fi xed temperatures (25, 30, 35, and 40°C) in two simultaneous experiments (enclosed and free-moving insects) were evaluated. Free-moving insects were marked daily according to their temperature preferences on each of the 15 days after inoculation. Numbers of insects in each temperature shelter and daily mortality were compared with those enclosed shelters of different temperatures. Results: Rhodnius prolixus inoculated with both strains of T. rangeli and with the trypanosome culture medium showed preferences for the lowest temperatures (25°C). However, R. prolixus inoculated with T. cruzi I showed signifi cant preferences for temperatures around 35°C. Conclusions: This is the fi rst known investigation to demonstrate a behavioral fever response in R. prolixus injected intracoelomically with T. cruzi I.

“…In particular, temperature has been found to be related to thermal preference processes [18][19][20], as well as host finding, feeding, egg production, hatching rate, immature development time, cessation of moulting and metabolic rate processes [21][22][23][24][25][26][27][28]. Climate change could therefore have effects on vital processes and consequently on the potential geographical distribution of both species, affecting ultimately the areas of Tr.…”

Chagas disease, caused by the parasite Trypanosoma cruzi , is the most important vector-borne disease in Latin America. The vectors are insects belonging to the Triatominae (Hemiptera, Reduviidae), and are widely distributed in the Americas. Here, we assess the implications of climatic projections for 2050 on the geographical footprint of two of the main Chagas disease vectors: Rhodnius prolixus (tropical species) and Triatoma infestans (temperate species). We estimated the epidemiological implications of current to future transitions in the climatic niche in terms of changes in the force of infection (FOI) on the rural population of two countries: Venezuela (tropical) and Argentina (temperate). The climatic projections for 2050 showed heterogeneous impact on the climatic niches of both vector species, with a decreasing trend of suitability of areas that are currently at high-to-moderate transmission risk. Consequently, climatic projections affected differently the FOI for Chagas disease in Venezuela and Argentina. Despite the heterogeneous results, our main conclusions point out a decreasing trend in the number of new cases of Tr. cruzi human infections per year between current and future conditions using a climatic niche approach.
