Abstract:  The weevil Scyphophorus acupunctatus Gyllenhal (Col., Curculionidae) is the most important insect pest of cultivated agaves in Mexico. The objective of this study was to search for potential attractants for this weevil species from the freshly cut fleshy leaves of healthy Agave tequilana Weber var. Blue plants. Combined gas chromatography‐electroantennography (GC‐EAD) analysis of A. tequilana volatile extracts showed that seven peaks elicited antennal responses from males and females… Expand
Aggregation pheromone of the agave weevil, Scyphophorus acupunctatus
TLDR
The potential use of the aggregation pheromone in the development of a mass‐trapping programme as a viable pest management alternative for S. acupunctatus is discussed. Expand
Electrophysiological responses and field attraction of the grey corn weevil, Tanymecus (Episomecus) dilaticollis Gyllenhal (Coleoptera: Curculionidae) to synthetic plant volatiles
TLDR
The present research is the first published electrophysiological study of olfactory sensitivity of adult T. dilaticollis to plant volatiles and these compounds could be developed into an attractive trap for the detection and monitoring of the grey corn weevil. Expand
Trapping Scyphophorus acupunctatus (Coleoptera: Curculionidae) with Fermented Tequila Agave, and Identification of the Attractant Volatiles
TLDR
The results obtained indicated that the fermented material was a viable alternative to optimize trapping of S. acupunctatus, because the liberated volatile chemical compounds of the attractant captured a greater number of weevils in the field. Expand
Olfactometer Responses of Plum Curculio Conotrachelus nenuphar (Herbst) (Coleoptera: Curculionidae) to Host Plant Volatiles, Synthetic Grandisoic Acid, and Live Conspecifics
The plum curculio Conotrachelus nenuphar (Herbst) (Coleoptera: Curculionidae) is a major pest of pome and stone fruit, but will also attack other fruits. Males produce the aggregation pheromoneExpand
Discovery and characterization of chemical signals for citrus root weevil, Diaprepes abbreviatus
TLDR
The biologically active compounds found here likely play a role in host finding by D. abbreviatus and other interactions of the insect with its hostplant. Expand
Behavioral and Electroantennographic Responses of Adults of Guava Weevil, Conotrachelus dimidiatus (Coleoptera: Curculionidae), to Synthetic Host-Associated and Conspecific Volatiles.
TLDR
This study assesses the behavioral and electrophysiological responses of the weevil to selected semiochemicals emitted by the host plant fruit and to conspecifics and indicates that synthetic compounds from host plant volatiles and insect volatile pheromones produce olfactometry and electroantennographic responses in C. dimidiatus. Expand
Behavioral Responses of Plum Curculio (Coleoptera: Curculionidae) to Different Enantiomer Concentrations and Blends of the Synthetic Aggregation Pheromone Grandisoic Acid
TLDR
Behavioural bioassays indicated that plum curculio were attracted to low concentrations of the (+) enantiomer at 72% enantiomersic excess, but that strainswere attracted to different concentrations ofThe (+) Enantiomer. Expand
Repellency of Hydroethanolic Extracts of Ricinus communis (Euphorbiaceae) to Scyphophorus acupunctatus (Coleoptera: Curculionidae) in the Laboratory
TLDR
The repellent effect of the hydroethanolic extract of the castor oil plant, Ricinus communis L. (Euphorbiaceae) wild and ‘Mirante’ cultivar on the adult's behavior is reported. Expand
Factors Affecting Pheromone Release by Scyphophorus acupunctatus (Coleoptera: Curculionidae)
TLDR
The results show that food is an important factor because weevils deprived of plant material did not release any pheromone, and it is found that males fed with apple, a nonhost plant, released less phersomone than weevil fed with agave. Expand
The physiological and behavioral responses of the lesser chestnut weevil, Curculio sayi (gyllenhal), to potential attractants : dose-response and interactions among host plant volatile organic compounds
TLDR
Mixtures were more attractive to adult C. sayi than individual compounds, and the highest behaviorally response was to the binary mixture of (E)-2hexenal and 2-heptanone. Expand

TLDR
A study aimed to elucidate the structure–activity relationships of aliphatic alcohols in Melolontha cockchafers and found males showed a stronger normalized EAG response to the stimuli than females. Expand
BEHAVIORAL AND ELECTROPHYSIOLOGICAL RESPONSES OF THE MEXICAN FRUIT FLY (DIPTERA: TEPHRITIDAE) TO GUAVA VOLATILES
TLDR
Analyzing the behavioral and electrophysiological responses of males and females of the Mexican fruit fly Anastrepha ludens to guava revealed that synthetic chemicals, sex, dose, and the synthetic chemical × dose interaction significantly influence the antennal response. Expand
RESPUESTAS DEL INSECTO MAX (SCYPHOPHORUS ACUPUNCTATUS GYLLENHAL (COLEOPTERA: CURCULIONIDAE)) HACIA ALGUNOS COMPUESTOS ATRAYENTES DEL HENEQUÉN
TLDR
The five main compounds from the most active extracts determined by GC-MS were: 4-ethyl cumene, p-metoxy-ethyl benzene, 1(methyl 4-(1-methyl ethyl) cyclohexanol,p-mentha-1,5dien-8-ol and butirofenone, which raises the possibility of using them in the control of this pest. Expand
Host Attractants for Red Weevil, Rhynchophorus ferrugineus: Identification, Electrophysiological Activity, and Laboratory Bioassay
TLDR
A twin FID peak consisting of a minor and a major component was shown to possess electrophysiological (EAG) activity and elicited moderate attractant properties to R. ferrugineus, whereas a 1:1 mixture of the compounds showed increased attraction over that of the individual compounds. Expand
Evidence for a Male-Produced Aggregation Pheromone in Scyphophorus acupunctatus Gyllenhal (Coleoptera: Curculionidae)

Evidence for a male-produced aggregation pheromone in Scyphophorus acupunctatus Gyllenhal (Coleoptera: Curculionidae).
TLDR
The field results support those of the laboratory bioassays, showing that males attracted conspecific males and females and addition of plant material enhanced the attraction, and suggest that S. acupunctatus produces an aggregation pheromone. Expand
