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

, 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.

An Automated Canine Line-Up for Detection Dog Research

Frontiers 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.

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

, 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.

Expanded olfactometer for measuring reaction time to a target odor during background odor presentation

Heliyon, 2019
Current olfactometers can insert a target odor into the flow of odorless air as a pulse (i.e., replace odorless air with target odor for a very short time), but no previously designed olfactometer can insert a pulse of target odor into a flow of ...

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

نامه 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

The role of volatiles in aggregation and host-seeking of the haematophagous poultry red mite Dermanyssus gallinae (Acari: Dermanyssidae) [PDF]

, 2010
Infestations with ectoparasitic poultry red mites (Dermanyssus gallinae) pose an increasing threat to poultry health and welfare. Because of resistance to acaricides and higher scrutiny of poultry products, alternative and environmentally safe management

Effectiveness of synthetic versus natural human volatiles as attractants for Anopheles gambiae (Diptera: Culicidae) sensu stricto [PDF]

, 2010
Females of the African malaria vector, Anopheles gambiae Giles sensu stricto, use human volatiles to find their blood-host. Previous work has shown that ammonia, lactic acid, and aliphatic carboxylic acids significantly affect host orientation and ...

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

نامه 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 ...

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

Frontiers 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 ...

Towards an attract-and-reward strategy: evaluating nectar resources and HIPVs under laboratory conditions to enhance Aphelinus mali parasitism activity, a key parasitoid of Eriosoma lanigerum. [PDF]

Pest Manag Sci
Euphorbia segetalis is a promising attractant insectary plant for Aphelinus mali. Meanwhile, Vicia faba and Vicia sativa are a promising nectar resource to sustain the parasitoid in early spring when the population of Eriosoma lanigerum is low, and honeydew is scarce.
