Repellence Produced by Monoterpenes on Rhodnius prolixus (Hemiptera: Reduviidae) Decreases After Continuous Exposure to These Compounds
(University of Arizona, 2014-01)
Botanical monoterpenes are secondary metabolites present in essential oils produced by plants. Some of them are insect repellents. The bloodsucking bug Rhodnius prolixus Ståhl (Hemiptera: Reduviidae) is one of the main ...
Female choosiness and mating opportunities in the blood-sucking bug Rhodnius prolixus
(Brill Academic Publishers, 2016-09)
We investigated the relationship between female choosiness and mating opportunities in the blood sucking bug Rhodnius prolixus. Rhodnius prolixus females exhibit active discrimination behaviour to male mating attempts which ...
The Octopamine Receptor Is a Possible Target for Eugenol-Induced Hyperactivity in the Blood-Sucking Bug Triatoma infestans (Hemiptera: Reduviidae)
(Entomological Society of America, 2019-10)
Eugenol is a major component of the essential oils in cloves and other aromatic plants. In insects, it produces toxic effects and repellency, and there is evidence that its site of action is the octopamine receptor. The ...
Effects of starvation on the olfactory responses of the blood-sucking bug Rhodnius prolixus
(Elsevier, 2013-07)
Blood-sucking insects use olfactory cues in a variety of behavioral contexts, including host-seeking and aggregation. In triatomines, which are obligated blood-feeders, it has been shown that the response to CO2, a ...
Toxicity, repellency and flushing out in Triatoma infestans (Hemiptera: Reduviidae) exposed to the repellents DEET and IR3535
(Peer J, 2017-05)
DEET and IR3535 are insect repellents present worldwide in commercial products; their efficacy has been mainly evaluated in mosquitoes. This study compares the toxicological effects and the behavioral responses induced by ...
Changes related to gender, geographic population and habitat in the antennal phenotype of Triatoma patagonica Del Ponte (Hemiptera: Reduviidae)
(Elsevier Science, 2013-02)
Triatomines undergo morphological changes as an adaptive response to different habitats (wild, peridomestic, domestic, laboratory). The characterization of the antennal phenotype provides information on intraspecific ...
Females sequential mating decisions depend on both the quality of the courting male and the quality of the potential mates in a blood-sucking bug
(Springer, 2018-09)
This study investigates whether female sequential decisions on accepting or rejecting a courting male are based exclusively on the quality of the male present or are affected by the quality of potential mates. We used ...
Females of a blood-sucking bug may adjust their mating decisions according to the risk of ovipositing infertile eggs
(Wiley Blackwell Publishing, Inc, 2019-12)
Females should adjust their mating preferences when the costs of being selective vary. Here, we focus on the cost of laying unfertilized eggs. Oviparous species lose their fertilizable oocytes if remain virgin for too long. ...
