An Automated Canine Line-Up for Detection Dog Research

open access: yesFrontiers in Veterinary Science, 2021
Currently, there is a need to develop technology that facilitates and improves detection dog research. The aim of this research was to develop an automated computer-driven olfactory line-up task. The apparatus consisted of three olfactometers.

Olfactory responses of Habrobracon hebetor (Hymenoptera: Braconidae) to carob moth, Ectomyelois ceratoniae (Lepidoptera: Pyralidae) and its host plant [PDF]

open access: yesنامه انجمن حشره‌شناسی ایران, 2020
Semiochemicals play a key role on host selection of parasitoids. Responses of parasitoid wasp, Habrobracon hebetor (Say), to volatiles emitted from Ectomyelois ceratoniae Zeller larva, pomegranate as its host plant and herbivorous induced plant volatiles

Host choice and host leaving in Rhopalosiphum padi (Hemiptera: Aphididae) emigrants and repellency of aphid colonies on the winter host [PDF]

open access: yes, 2000
Host choice and winter-host leaving in emigrants of bird cherry–oat aphid, Rhopalosiphum padi (Linnaeus), were investigated in the laboratory. In settling choice tests, emigrants collected from the winter host, Prunus padus, preferred this plant over ...

Silencing the Odorant Binding Protein RferOBP1768 Reduces the Strong Preference of Palm Weevil for the Major Aggregation Pheromone Compound Ferrugineol

open access: yesFrontiers in Physiology, 2018
In insects, perception of the environment—food, mates, and prey—is mainly guided by chemical signals. The dynamic process of signal perception involves transport to odorant receptors (ORs) by soluble secretory proteins, odorant binding proteins (OBPs ...

Host-specific cues cause differential attractiveness of Kenyan men to the African malaria vector Anopheles gambiae [PDF]

open access: yes, 2002
Background Many studies have suggested that variability in the attractiveness of humans to host-seeking mosquitoes is caused by differences in the make-up of body emanations, and olfactory signals in particular.

Role of volatile compounds emitted from the first and second trophic levels in host finding behavior of Tamarixia radiata (Hym.: Eulophidae) [PDF]

open access: yesنامه انجمن حشره‌شناسی ایران, 2013
Odors play an important role in the seeking behavior of wasp parasitoids and enhances their performance in biological control programs. This study was intended to determine the olfactory response of Tamarixia radiata (Waterston) to chemical cues that ...

Egg parasitoid exploitation of plant volatiles induced by single or concurrent attack of a zoophytophagous predator and an invasive phytophagous pest [PDF]

open access: yes, 2019
Zoophytophagous insect predators can induce physiological responses in plants by activating defence signalling pathways, but whether plants can respond to facultative phytophagy by recruiting natural enemies remains to be investigated.

Chocolate Classification by an Electronic Nose with Pressure Controlled Generated Stimulation

open access: yesSensors, 2016
In this work, we will analyze the response of a Metal Oxide Gas Sensor (MOGS) array to a flow controlled stimulus generated in a pressure controlled canister produced by a homemade olfactometer to build an E-nose. The built E-nose is capable of chocolate

The Role of Carbon Dioxide in Host-Finding by Mosquitoes (Diptera: Culicidae): A Review [PDF]

open access: yes, 1980
\ud From a critical review of the literature, it is concluded that the role of carbon dioxide in host-seeking by mosquitoes comprises two distinct actions.

Odour-mediated sexual attraction in nabids (Heteroptera: Nabidae)

open access: yesEuropean Journal of Entomology, 2008
In many insects, mate finding is mediated by volatile sex pheromones, but evidence in nabids is still fragmentary. The role of odour-mediated sexual attraction in two nabid species, Nabis pseudoferus and N.
