A CO 2 -Free Synthetic Host–Odor Mixture That Attracts and Captures Triatomines: Effect of Emitted Odorant Ratios
(Entomological Society of America, 2016-07)
Triatomines, vectors of Chagas Disease, are hematophagous insects. Efforts have been made to develop synthetic attractants based on vertebrate odor—to lure them into traps. However, because those lures are not practical ...
Morphology and physiology of the olfactory system of blood-feeding insects
(Elsevier, 2014-04)
Several blood-feeding (hematophagous) insects are vectors of a number of diseases including dengue, Chagas disease and leishmaniasis which persistently affect public health throughout Latin America. The vectors of those ...
Head Lice Recognize and Prefer Head Odor over Foot and Forearms Odors
(Entomological Society of America, 2019-09)
Human head lice, Pediculus humanus capitis De Geer (Phthiraptera: Pediculidae), are hematophagous parasites that infest human heads. They are extreme host specialists suggesting a strict selection behavior towards the human ...
To smell you better: prior food deprivation increases herbivore insect responsiveness to host plant odor cues
(Springer, 2016-08)
Hunger plays a crucial role in insect feeding behavior, however food deprivation is rarely considered when insect responses to plant host and related chemical stimuli are investigated. Here we assessed, by means of experiments ...
Fall Armyworm, Spodoptera frugiperda (JE Smith) (Lepidoptera: Noctuidae), Female Moths Respond to Herbivore-Induced Corn Volatiles
(ENTOMOLOGICAL SOC BRASILLONDRINA,, 2012)
In response to herbivore attack, plants release herbivore-induced plant volatiles (HIPVs) that represent important chemical cues for herbivore natural enemies. Additionally, HIPVs have been shown to mediate other ecological ...
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 ...
Investigação de assinaturas de seleção positiva em genes associados à localização do hospedeiro em espécies do grupo repleta de Drosophila
(Universidade Estadual Paulista (Unesp), 2022-01-27)
The host changes observed in the repleta group of Drosophila, in which the ancestral character state is the use of cacti of the genus Opuntia as hosting and reproduction sites, for the use of chemically more complex columnar ...
Comparison of BG-Lure and BG-Sweetscents attractants for field sampling of phlebotomine sand flies
(2020-02-01)
Phlebotomines are important vectors of bacteria, viruses and protozoan parasites. Protozoans of the genus Leishmania which cause visceral and cutaneous leishmaniases, are among the most important etiologic agents transmitted ...
Virtual Screening of Plant Volatile Compounds Reveals a High Affinity of Hylamorpha elegans (Coleoptera: Scarabaeidae) Odorant-Binding Proteins for Sesquiterpenes From Its Native Host
(2016)
Hylamorpha elegans (Burmeister) is a native Chilean scarab beetle considered to be a relevant agricultural pest to pasture and cereal and small fruit crops. Because of their cryptic habits, control with conventional methods ...
Oviposition in the blood-sucking insect Rhodnius prolixus is modulated by host odors
(BioMed Central, 2015-05)
Background: Triatomine bugs are blood-sucking insects, vectors of Chagas disease. Despite their importance, their oviposition behavior has received relatively little attention. Some triatomines including Rhodnius prolixus ...
