“…The sex pheromone of the pink bollworm moth, Pectinophora gossypiella, has been identified as a mixture of two attractant compounds: Z7Zll-16:Ac and Z7EII-16:Ac in a ratio of 1:1, called gossyplure (Hummel et aL, 1973). In contrast to most other known cases of moths using a discrete ratio of components, comparable trap catch is evoked over a wide range of ratios (Flint et aL, 1979). Flint and Merkle (1984a) found that in an atmosphere permeated only with the (Z,Z)-isomer component of gossyplure, higher numbers of male moths were caught in traps baited with an excess of the (Z,Z)-isomer than in the gossyplure-baited traps.…”

It is widely assumed that a blend of pheromone components, that is qualitatively and quantitatively similar to the natural sex attractant, is the most effective mating disruptant for moths. However, the literature contains only limited evidence supporting this assumption. The authors discuss the importance of comparing the relative effectiveness of complete and incomplete pheromone blends when evaluating the potential of mating disruption for controlling pest moths.

“…These findings triggered subsequent studies on the identification and evaluation of some intermediate products until the sex pheromone of the pink bollworm (''gossyplure'', a mixture of the Z.Z-and Z.E-isomers of 7,11-hexadacadienyl acetate) was identified (Hummel et al 1973). A mixture of the two isomers at a ratio of 50 or 60% proved appropriate for monitoring or control of pink bollworm (Flint et al 1979). Gossyplure has been used widely for monitoring the pink bollworm (Bariola et al 1973, Qureshi et al 1984 and proved to be more effective in reducing damage levels by the pink bollworm than several insecticidal applications .…”

Mating disruption of the pink bollworm Pectinophora gossypiella (Saund.) (Lepidoptera: Gelechiidae) using gossyplure PB-rope dispensers in cotton fields

et al. 2004

The effects of mating disruption on population densities and percentage of damage of the pink bollworm Pectinophora gossypiella (Saunders) were investigated in a cotton field in central Greece, in 1992 and. A 10-ha field was divided in two parts of 5 ha each. PB-rope dispensers were installed in midseason in one part, whereas the other was used as a control field. Catches of pink bollworm moths in pheromone-baited traps and damage caused were recorded in both the treated and control fields. Results showed that moth catches were highly reduced in the treated field and, therefore, mid-season installation of dispensers was successful. Damage (%) was significantly less in the treated compared with the control field. Consequently, the field size of 5 ha seems to be adequate for the effective implementation of mating disruption.

“…The mixture of ZZ and ZE7,11-16:Ac has been identified as the sex pheromone of Pectinophora gossypiella (Hummel et al, 1973), furthermore, P. endema (Rothschild, 1975), Pexicopia sp. (Flint, 1979) and Catelaphris sp. (Marks, 1976) have been reported to be attracted to it.…”

Pexicopia malvella (Hbn.) males were attracted to mixtures containing (Z,E)‐7,ll‐hexadecadienyl acetate and (Z,Z)‐7,ll‐hexadecadienyl acetate, in screening tests, in Hungary. An approximate dose of 40 μg 5:1 ZE:ZZ mixture is recommended for practical use as a selective and potent sex attractant. Platyedra subcinerea (Hw.), another gelechiid pest, was attracted best to a 300 μg dose of (Z,Z)‐7,ll‐hexadecadienyl acetate. Zusammenfassung Sexuallockstoffe für Pexicopia malvella und Platyedra subcinerea, Schädlinge von Zierpflanzen der Familie Malvaceae und Baumwolle Die binäre Mischung von (Z,Z)‐7,ll‐hexadeka‐dienylacetat und (Z,E)‐7,ll‐hexadekadienylacetat erwies sich im Freiland als Sexuallockstoff für Männchen von P. malvella (Gelechiidae, Lepidop‐tera). Die Verhältnisse 1:1, 1:1.4, 1:2.5, 1:5 und 1:10 lockten bedeutende Anzahlen von Männchen, die Komponenten allein waren unwirksam. Die Mischung in Verhältnis 1:5 und bei der Köderbeladung von ungefähr 40 μg kann zur praktischen Anwendung als ein spezifisches und effektives Lockstoff empfehlt werden. Männchen von P. subcinerea (= vilella Gelechiidae, Lepidoptera) wurden zu Fallen mit dem Isomer (Z,Z) angelockt. Beste Fangergebnisse wurden mit der Köderbeladung 300 μg (Z,Z)‐7,ll‐hexa‐dekadienylacetat erreicht. P. malvella wird in Ungarn als bedeutungsvoller Schädling von Zierpflanzen der Familie Malvaceae gemeldet, und alle beide Arten sind als Baumwolleschädlinge in zentralasiatischen Sovietrepub‐liken und anderen Ländern in Asien bekannt.
