Spittler, Terry D. published the artcileBiorational control of crop pests by mating disruption. Residue analyses of Z-9-dodecen-1-yl acetate and Z-11-tetradecen-1-yl acetate in grapes, Category: esters-buliding-blocks, the publication is ACS Symposium Series (1988), 430-6, database is CAplus.
(Z)-9-Dodecen-1-yl acetate (I) and (Z)-11-tetradecen-1-yl acetate (II), primary components of grape berry moth pheromone, were applied in vineyards via tie-on dispensers for the entire growing season. Mature grapes (100 g) were blended and extracted with acetone; following the addition of water, the analytes were extracted into hexane which, after evaporation, was adsorbed onto a Florisil Sep-pak. Elution was with 10% acetone in hexane. Chromatog. was on a Supelcowax 10 capillary column with temperature programming from 80 to 130° at 5°/min then 130 to 200 at 4°/min with a hold 9 min. Detection by HP-MSD Model #5970B was in the selective ion mode at 166 m/e and 194 m/e for I and II, resp. Corresponding retention times were 17.7 and 22.7 min. The sensitivity was <5 ppb for both materials at 80% recovery. Insect control by this biotech. approach was good, and it eliminated the use of traditional chem. pesticides against grape berry moth. No residues were detected in grape berries.
ACS Symposium Series published new progress about 16974-11-1. 16974-11-1 belongs to esters-buliding-blocks, auxiliary class Aliphatic Chain, name is (Z)-Dodec-9-en-1-yl acetate, and the molecular formula is C9H6BrNO2, Category: esters-buliding-blocks.
