Lepidopteran sex pheromones are aliphatic compounds with limited functional groups, and are synthesized de novo in the pheromone gland from acetyl-CoA through the fatty acid biosynthetic pathway. A neurohormone termed pheromone-biosynthesis-activating neuropeptide (PBAN) regulates sex pheromone production in a number of lepidopteran species. With the aim of promoting general understanding, we r...

The Drosophila sex pheromone cVA elicits different behaviors in males and females. First- and second-order olfactory neurons show identical pheromone responses, suggesting that sex genes differentially wire circuits deeper in the brain. Using in vivo whole-cell electrophysiology, we now show that two clusters of third-order olfactory neurons have dimorphic pheromone responses. One cluster respo...

After the wind was stopped in an insect flight tunnel, male oriental fruit moths continued to fly in zigzag fashion along a stationary pheromone plume. Their lateral excursions from the time-averaged pheromone plume were no greater without wind than in wind of 38 centimeters per second. When the pheromone plume was removed and the wind stopped, males initiated wider track reversals when they re...

Riptortus pedestris (Hemiptera: Alydidae) is a serious pest of soybean and sweet persimmon uses male produced aggregation pheromone, (E)-2-hexenyl (Z)-3-hexenoate, (E)-2-hexenoate, tetradecyl isobutyrate to facilitate food location recognition by conspecifics. Using electroantennogram (EAG) greenhouse bioassay, we determined which antennal segment involved in the detection their pheromone. In f...

A 14-mer alpha-pheromone peptide of Candida albicans was chemically synthesized and used to analyze the role of white-opaque switching in the mating process. The alpha-pheromone peptide blocked cell multiplication and induced "shmooing" in a/a cells expressing the opaque-phase phenotype but not in a/a cells expressing the white-phase phenotype. The alpha-pheromone peptide induced these effects ...

Mating in Candida albicans and Saccharomyces cerevisiae is regulated by the secretion of peptide pheromones that initiate the mating process. An important regulator of pheromone activity in S. cerevisiae is barrier activity, involving an extracellular aspartyl protease encoded by the BAR1 gene that degrades the alpha pheromone. We have characterized an equivalent barrier activity in C. albicans...

J. Econ. Entomo!' 88(4): 864--869 (1995) ABSTRACT Combinations of aggregation pheromones for 3 nitidulid beetle species, Carpophillls hel1lipterlls (L.), C. 11l11tilatlls Erichson, and C. freel1lani Dobson, were evaluated as trap baits in a date garden in southern California. All possible 2and 3-way combinations "'ere compared \\ith the single pheromones; fermenting whole wheat bread dough was ...

In Enterococcus faecalis, sex pheromone-mediated transfer of antibiotic resistance plasmids can occur under unfavorable conditions, for example, when inducing pheromone concentrations are low and inhibiting pheromone concentrations are high. To better understand this paradox, we adapted fluorescence in situ hybridization chain reaction (HCR) methodology for simultaneous quantification of multip...

Plasmid-free strains of Enterococcus faecalis secrete a peptide sex pheromone, cAD1, which specifically induces a mating response by donors carrying the hemolysin plasmid pAD1 or related elements. A determinant on the E. faecalis OG1X chromosome has been found to encode a 46.5-kDa protein that plays an important role in the production of the extracellular cAD1. Wild-type E. faecalis OG1X cells ...
