“…Electroantennographic (EAG) responses from male moths to natural and synthetic compounds were recorded as described by Nesbitt et al (1977) and Hall et al (1984). Gas chromatographic (GC) analyses with simultaneous recording of EAG responses to the column effluent were carried out as described by Moorhouse et al (1969) and Hall et al (1984).…”

The sex pheromone produced by virgin female S. solanivora moths has been shown to contain (E)‐3‐dode‐cenyl acetate with approximately 2% of the Z isomer by electroantennography and gas chromatography. In the field, traps baited with (E)‐3‐dodecenyl acetate alone or in combination with 1 % or 2% of the Z isomer caught at least as many male S. solanivora moths as those baited with virgin female moths, and there was some evidence that addition of 5% of the Z isomer reduced catches. RÉSUMÉ Identification des constituants de la phéromone sexuelle femelle de la Teigne de la Pomme de Terre, Scrobipalpopsis solanivora Pov. S. solanivora est l'un des plus importants lépidoptères détruisant les pommes de terre en Amérique Centrale. L'analyse par chromatographic en phase gazeuse (GC) des produits obtenus par lavage de l'ovipositeur de femelles vierges, associée à des électro‐anténnogrammes (EAG) a révélé un composé actif unique en EAG. Les durées de rétention pour ce constituant correspondaient à celles des acétates monoinsaturés à 12 carbones, et les analyses sur colonne GC liées avec une phase liquide cristal ont montré un pic principal correspondant à l'acétate (E)‐3‐dodécényl et un pic secondaire, correspondant à l'isomère Z, et au niveau de 2,5% du pic principal. L'acétate dodécyl a aussi été décelé en quantités variables, approximativement 10% du pic principal. Dans la nature, des pièges contenant de l'acétate (E)‐3‐dodécényl, seul ou mélangé avec 1 ou 2% de l'isomère Z, ont capturé autant des mâles de S. solanivora que des pièges contenant des femelles vierges, et certaines indications montrent que l'addition de 5% de l'isomère Z réduit les captures.

“…A turning point in the control of this pest occurred with the identification and synthesis of the pheromone ofP. citri by Nesbitt et al (1977). Field experiments with the synthetic sex pheromone to control P. citri started in 1976, with the aim of eliminating further insecticide use against this pest.…”

Preliminary field trials on the control of Prays citri (Milli6re) (Lepidoptera: Yponomeutidae) by mass trapping were carried out from 1976 using synthetic sex pheromone (Z-7-tetradecenal) baited traps. A clear tendency was revealed for a reduction in flower infestation by the larvae of this pest, providing that the minimum required number of traps (120 per ha) were employed and maintained throughout the entire year. In 1980-1983, commercial field trials were conducted over 30 ha of lemon trees. Rubber septa dispensers were loaded with 0.5-0.6 mg synthetic pheromone and refilled every four months. For comparison, about 30 ha lemon trees were sprayed 3-6 times a year with an organophosphate (azinphos-methyl) insecticide treatment. One plot of 0.22 ha was used as control. Results from all three areas were compared for mean male catch per trap per day, mean number of moths emerging per flower, and fruit yield for the two years prior to the trials and the three years of the trials in all plots. Lemon trees without control measures showed a decline in fruit yield. Controlling the moth by mass trapping of males, was significantly (P < 0.05) cheaper and somewhat more efficient than spraying 3-6 times/year with insecticides.

The citrus pock caterpillar, Prays endocarpa (Yponomeutidae; Praydinae), is a pest of pomelo (Citrus grandis L.) in Vietnam. Gas chromatography-mass spectrometry analyses of pheromone gland extracts from female moths identified three monoenyl compounds, (Z)-7-tetradecenal (Z7-14:Ald), (Z)-7-tetradecenyl acetate (tentatively identified, Z7-14:OAc), and (Z)-7-tetradecen-1-ol (Z7-14:OH), in a ratio of about 10:3:10. In the field, traps baited with synthetic Z7-14:Ald (0.5 mg) caught male P. endocarpa. The other two compounds, either alone or when added to Z7-14:Ald, did not elicit increases in trap catch (relative to the appropriate treatment). Synthetic Z7-14:Ald was used to monitor and control this species in pomelo orchards in Vinh Long Province. Monitoring revealed that adults were present throughout the year with discernible peaks in December, March, and April. A mass-trapping trial, using 20 traps in a 0.1 ha pomelo orchard, effectively suppressed fruit damage to levels similar to that achieved by an insecticide (Karate 2.5EC). Mating disruption trials, using polyethylene-tube dispensers, each filled with 80 mg of Z7-14:Ald at a rate of 200 or 400 dispensers/ha, also controlled damage by this pest to levels below that achieved by an insecticide treatment. This work demonstrates the potential for pheromone-based control of this pest in Vietnam.
