Abstract:
By means of GC, GC-MS and GC-combined EAG recordings (9Z,12E)-9,12-tetradecadien-1-ol (1) and (9Z,12E)-9,12-tetradecadienyl acetate (2) in a ratio of 4:1 were identified as the pheromone components of the female pyralid moth Euzophera punicaella M. originating from Armenia. Determination of EAG activity with male moth antennae and synthetic test chemicals revealed best responses with a mixture of both compounds.

Abstract:
Electrophysiological responses based on electroantennographic detection (GC-EAD) and electroantennography (EAG) analysis of Naupactus bipes beetles (Germar, 1824) (Coleoptera: Curculionidae: Brachycerinae) were used to test volatile oils of Piper gaudichaudianum, P. regnellii and P. hispidum. In the EAG experiments, female and male beetles showed significant EAG response to the three volatile oils of Piper species, with the females’ responses slightly higher than the males’. The experiments with GC-EAD revealed that some terpenoids (namely, α-pinene, β-pinene, myrcene, α-copaene and germacrene

Abstract:
Background A combination of gas chromatography-electroantennographic detection (GC-EAD) and gas chromatography-mass spectrometry (GC-MS) is typically used to screen active compounds that play a role in the regulation of insect behavior. This method uses two kinds of gas chromatography (GC) equipment and needs to compare compounds between the two chromatograms, and it is tedious and costly. To improve detection efficiency, as well as reduce costs and the rate of missed detection, we designed a system connecting gas chromatography (GC), electroantennography (EAG), and mass spectrometry (MS), wit

Abstract:
Abstract Tea black tussock moth, Dasychira baibarana (Matsumura) (Lepidoptera: Lymantriidae), is a devastating pest species of the tea plant in China. Here, we evaluated the responses of D. baibarana to tea plant volatiles using gas chromatography coupled electroantennographic detection (GC–EAD), eleclectroantennography (EAG), and a Y-tube olfactometer. In total, 11 of 18 analyzed compounds elicited GC–EAD responses from test insects. GC–EAD bio-active compounds were further investigated using EAG and behavioral responses. In the EAG analysis, male moths had significantly greater responses to

Abstract:
The scent secretions of two subspecies of Hebomoia glaucippe, which are pierid butterflies, and the essential oils of their food plant were investigated by means of GC and GC-MS. The scent substances of either subspecies are found to be only E-β-ocimene, and the volatile components of Crataeva religiosa were identified as 2-hexanal, 3-hexen-1-ol, p-cymene, limonene, linalool, α-ionone, and β-ionone. Electroantennogram (EAG) were recorded with the antennae of adult male and female butterflies. It was found that EAG responses of male to E-β-ocimene were greater than those of females.

Abstract:
European cherry fruit fly, Rhagoletis cerasi (Diptera: Tephritidae), is the most important pest of sweet and sour cherry fruit. This fly is difficult to control by insecticide application since most of the conventional insecticides used have been banned in Europe. Traps are used for both the pest’s mass trapping and the detection of the beginning of the flight period. Data on flies’ reactions to host-plant volatile organic compounds (VOCs) can be used to search for new attractants. VOCs were collected from the headspace of sour cherry, P. cerasus, fruit.

Abstract:
Electroantennography (EAG) is a simple, yet powerful technique that can be used to indicate that chemical compounds are detected by mosquito antennae. When coupled with gas chromatography (GC), it allows for the identification of detectable compounds within complex mixtures, including those in plant and animal headspaces that might influence mosquito behavior. EAGs and GC-EAGs reveal compounds that can be tested in behavioral assays with the goal of developing new repellents or attractants for mosquito control.

Abstract:
Les signaux olfactifs sont d’une importance cruciale pour la localisation d’hôte par les insectes, afin que ces derniers effectuent leurs besoins primaires nécessaires à leur survie et à celle de leurs progénitures. Les insectes s’orientent en détectant et discriminant les composés volatils émis par leurs hôtes via leurs organes olfactifs. La diversité d’information portée par les multiples composés volatils présents dans l’environnement contraint les insectes à utiliser des stratégies olfactives efficaces. Toutefois, ces stratégies demeurent peu connues pour les espèces à large gamme d’hôte c
