Identification and Field Bioassays of the Sex Pheromone of Synanthedon haitangvora
Two major components from pheromone gland extracts of Synanthedon haitangvora females were identified as (Z,Z)-3,13-octadecadienyl acetate (Z3,Z13-18:OAc) and (E,Z); and the average ratio of these components was about 1:1. Expand
RNA interference of pheromone biosynthesis-activating neuropeptide receptor suppresses mating behavior by inhibiting sex pheromone production in Plutella xylostella (L.).
The identified PBAN receptor is functional in PBAN signaling via calcium secondary messenger, which leads to activation of pheromone biosynthesis and male attraction. Expand
Sex Pheromones and Reproductive Isolation in Five Mirid Species
The combined results from this study and previous studies suggest that the minor component and pheromone dose in addition to the relative ratio of the major components play an important role in reproductive isolation between mirid species. Expand
Sex pheromone production and response in Korean populations of the diamondback moth, Plutella xylostella
The results suggest that there is geographical variation in the pheromone systems of the diamondback moth, Plutella xylostella, and the highest attraction is obtained with a 10:90 blend mimicking the blend found in gland extracts. Expand
Model of Grapholita molesta spring emergence in pear orchards based on statistical information criteria
A model to precisely predict the spring occurrence of G . Expand
Identification of the Female-Produced Sex Pheromone of the Plant Bug Apolygus spinolae
Field trapping tests with various blends of the synthetic compounds dispensed from high-density polyethylene tubes showed that (E)-2-hexenyl butyrate and (E-4-oxo-2- hexenal were essential for attraction of male A. spinolae, and catches with a wide range of ratios of these two compounds did not differ significantly.

Sex Pheromones and Reproductive Isolation of Three Species in Genus Adoxophyes
These minor components, in addition to the relative ratios of the two major components, play an important role in reproductive isolation between Adoxophyes species in the southern and midwestern Korea where these species occur sympatrically. Expand
Sex Pheromone Composition and Monitoring of the Oriental Fruit Moth, Grapholita molesta (Lepidoptera: Tortricidae) in Naju Pear Orchards
Analysis of seasonal trap catches over three years summarizes that the oriental fruit moth has four main generation peaks over at least seven months per year in Naju. Expand
Molecular Diagnosis of Grapholita molesta and Grapholita dimorpha and Their Different Occurrence in Peach and Plum
The plume fruit moth, Grapholita dimorpha Komai, a fruit tree pest occurring in the northeast Asia, was firstly reported to infest apple in Korea in 2009, but its direct damage to other fruit treesExpand
Identification and field testing of sex pheromone components of a Korean population of the allium leafminer, Acrolepiopsis sapporensis
Field trapping experiments indicated that all three pheromone components were essential for maximal attraction of male moths. Expand
