1-octadecene, A Female Produced Aggregation Pheromone of the Coffee White Stem Borer (Xylotrechus quadripes)

چکیده
Coffee white stem borer, Xylotrechus quadripes is a serious insect pest of coffee across the world. Pheromone traps baited with male produced 2-hydroxy- 3-decanone (2H3D) attracted females, and also males. Interestingly, pair males females in cage more beetles compared to 2H3D traps. We hypothesized volatiles emitted from are perceived by Volatiles were collected through air entrainment method identified 1-octadecene using gas chromatography coupled mass spectrometry. Release was female specific, however, both antennae elicited responses chromatography-electroantennography. Electroantennogram dose-dependent sexes higher females. Combination pheromone component 2H3D, at 1:2 ratio increased (0.69 ± 0.13; mean SEM -mV) (0.98 0.20) antennal responses. Responses constant doses increasing (1:4, 1:6, 1:8, 1:10) not different alone. Beetle captures alone 3 (75, 150 300 mg) significantly live beetle A blend trapped (3.50 0.65; SEM) over (2.00 0.82), overall, our experiments suggest an aggregation pheromone. Our results support hypothesis that use mate finding, potential it for monitoring trapping.

Transcripts of pectin-degrading enzymes and isolation of complete cDNA sequence of a pectate lyase gene induced by coffee white stem borer (Xylotrechus quadripes) in the bark tissue of Coffea canephora (robusta coffee)
Of the two commercially cultivated coffee (Coffea) species, C. arabica (arabica) is highly susceptible and C. canephora (robusta) is highly resistant to the insect pest Xylotrechus quadripes (Coleoptera: Cerambycidae), commonly known as coffee white stem borer (CWSB). We constructed a forward-subtracted cDNA library by Suppression Subtractive Hybridization (SSH) from robusta bark tissue for pro...
متن کاملCoffee Berry Borer Resistance in Coffee Genotypes
The aim of this study was to evaluate the coffee germplasm of the Paraná Agronomic Institute (IAPAR) for resistance to the coffee-berry-borer. Preliminary field evaluation was performed in August 2004 and the fruits of less damaged genotypes in the field were evaluated under controlled condition with obligated and free choice experiments established in a randomized complete design with three re...
متن کاملA facile asymmetric synthesis of (s)-14-methyl-1-octadecene, the sex pheromone of the peach leafminer moth.
An asymmetric synthesis of 14-methyl-1-octadecene, the sex pheromone of the peach leafminer moth has been achieved. The target molecule was synthesized in six linear steps and in 30.3% overall yield from commercially available hexanoyl chloride, (S)-4-benzyloxazolidin-2-one and 1,9-nonanediol. The hexanoyl chloride was connected with (S)-4-benzyloxazolidin-2-one, and with the induction of the c...
متن کاملElectroantennogram Responses of Both Sexes of Grape Root Borer (Lepidoptera: Sesiidae) to Synthetic Female Sex Pheromone
The effect of mating status and sex on antennal response to sex pheromone components was tested in the grape root borer, Vitacea polistiformis (Harris). The grape root borer pheromone is a 99:1 blend of (E,Z)-2,13-octadecadien-1-ol acetate (EZ) and (Z,Z)-3,13octadecadien-1-ol acetate (ZZ). Antennae of both virgin male and female moths exhibited similar doseÐresponse patterns, with a threshold d...
