Volatile Esters of Bartlett Pears ^{a, b}

Journal of Food Science, 1961
SUMMARY Esters are responsible for the typical desirable aroma of Bartlett pear. Hydrolysis products of these esters were resolved by gas chromatography. The major ester acid is an unsaturated 10 carbon acid, which hydrogenates to yield n‐ capric acid, as identified by ...

Binding Affinity of the Methyl Ester of AK-toxin I to Membrane Fractions from Japanese Pear Leaves

Bioscience, Biotechnology, and Biochemistry, 2000
The binding site of AK-toxin, a host-specific toxin against Japanese pear, was searched for in the membrane fractions of the pear leaves, using 3H-labeled AK-toxin I methyl ester. Binding activity, which was displaceable by the unlabeled ligand, was observed for microsomal fraction from a toxin-susceptible cultivar, Nijisseiki. However, the binding was

Activity of Sugar Esters Isolated from Leaf Trichomes of Nicotiana gossei to Pear Psylla (Homoptera: Psyllidae)

Journal of Economic Entomology, 1995
Insecticidal activity of a sugar ester fraction isolated from leaf trichomes of wild tobacco, Nicotiana gossei Domin, to egg, nymph, and adult stages of pear psylla, Cacopsylla pyricola Foerster, was determined in replicated laboratory bioassays. Aqueous solutions of sugar ester concentrations ranging from 62 to 1,000 ppm (mg/liter) were applied by an ...

Monitoring codling moth (Lepidoptera: Tortricidae) in orchards treated with pear ester and sex pheromone combo dispensers

Journal of Applied Entomology, 2012
AbstractMonitoring codling moth, Cydia pomonella (L.), with its sex pheromone (E,E)‐8,10‐dodecadien‐1‐ol (codlemone) alone or in combination with plant volatiles (PH‐plant volatile lures) with and without the addition of an acetic acid (AA) lure was compared in apple and walnut orchards treated with PVC Cidetrak® dispensers (CM‐DA Combo) loaded with 60

Co-application of microencapsulated pear ester and codlemone for mating disruption of Cydia pomonella

Journal of Pest Science, 2014
Studies were conducted in two apple orchards in 2009 and 2010 to examine whether the efficacy of mating disruption can be improved by co-applying microencapsulated (MEC) pear ester (DA-MEC) and codlemone (Ph-MEC) in comparison to DA-MEC and Ph-MEC treatments alone.
