Identification of Volatile Synomones, Induced by Nezara viridula Feeding and Oviposition on Bean spp., That Attract the Egg Parasitoid Trissolcus basalis
Findings indicate that N. viridula feeding and oviposition induce leguminous plants to produce blends of volatiles that are characterized by increased amounts of (E)-β-caryophyllene, and these blends attract female T. basalis females. Expand
Development and Optimization of Methods for Using Sex Pheromone for Monitoring the Mealybug Planococcus ficus (Homoptera: Pseudococcidae) in California Vineyards
Comparison ofVisual sampling methods and sampling of males with pheromone-baited traps revealed that trap catches were significantly correlated with the results from visual sampling methods, and with economic damage. Expand
Using Generic Pheromone Lures to Expedite Identification of Aggregation Pheromones for the Cerambycid Beetles Xylotrechus nauticus, Phymatodes lecontei, and Neoclytus modestus modestus
Overall, the attraction of multiple species from different cerambycine tribes to this compound at a single field site supports the hypothesis that the hydroxyketone pheromone structural motif is highly conserved within this subfamily. Expand
Identification of a Male-Produced Aggregation Pheromone for Monochamus scutellatus scutellatus and an Attractant for the Congener Monochamus notatus (Coleoptera: Cerambycidae)
ABSTRACT We report identification and field testing of 2-(undecyloxy)-ethanol (monochamol) as a sex-specific, aggregation pheromone component produced by males of Monochamus scutellatus scutellatusExpand
Phoracantha semipunctata (Coleoptera: Cerambycidae), a Serious Pest of Eucalyptus in California: Biology and Laboratory-Rearing Procedures
An experiment on adult beetle diet showed that the provision of Sucrose water greatly increased longevity and fecundity over a distilled water control, but increasing the concentration of sucrose >5% did not significantly improve beetle performance. Expand
Identification, Synthesis, and Field Testing of the Sex Pheromone of the Citrus Leafminer, Phyllocnistis citrella
It is reported here that (7Z,11Z)-hexadecadienal is only one component of the pheromone, with the other critical component being the analogous trienal, ( 7Z, 11Z,13E)-hexADEcatrienal, which was identified in the effluvia from live female moths by coupled gas chromatography-electroantennography using nonpolar and polar GC columns.

Response of the Woodborers Monochamus carolinensis and Monochamus titillator (Coleoptera: Cerambycidae) to Known Cerambycid Pheromones in the Presence and Absence of the Host Plant Volatile
Results indicate that monochamol is a male-produced pheromone for both M. carolinensis and M. titillator, and that antennae of males and females of both species detect it. Expand
Attraction of female Culex quinquefasciatus Say (Diptera: Culicidae) to odors from chicken feces.
Odors from fresh chicken feces in water elicited upwind flight of host-seeking female Culex quinquefasciatus mosquitoes in a dual-choice olfactometer, the first reported example of avian fecal odor eliciting upwindFlight of female mosquitoes. Expand
Chemical and Physical Signals Mediating Conspecific and Heterospecific Aggregation Behavior of First Instar Stink Bugs
When tested over a range of doses, groups of polysulfone beads treated with crude whole-body extracts of bugs did not induce or maintain aggregations, however, first instar N. viridula nymphs did respond to beads treating with two of the three major components of bug extracts. Expand
Determination of the Relative and Absolute Configurations of the Female-produced Sex Pheromone of the Cerambycid Beetle Prionus californicus
Stereoselective syntheses of three of the four possible stereoisomers are described, and the results of laboratory and field bioassays showing that male beetles are attracted specifically to (3R,5S)-3,5-dimethyldodecanoic acid, but not to its enantiomer are shown, indicating that the (3S,5R)-enantiomer is the active pheromone component.
