New sex attractants for male Lepidoptera (Coleophoridae, Gelechiidae, Momphidae, Oecophoridae, and Yponomeutidae) found by field screening in The Netherlands

Abstract

By screening 48 mono‐unsaturated alkenyl acetates with chain lengths of 10, 12, 13, 14, and 16 carbon atoms singly and in binary mixtures sex attractants were discovered for fourteen species of Lepidoptera: Coleophora frischella, C. vacciniella (Coleophoridae), Brachmia blandella, B. inornatella, Bryotropha galbanella, B. senectella, Chionodes electella, Gelechia sororculella, Monochroa tenebrella, Sophronia semicostella (Gelechiidae), Batrachedra pinicolella (Momphidae), Bisigna procerella, Pseudatemelia spp. (Oecophoridae), and Ocnerostoma friesei (Yponomeutidae). Results are briefly discussed with regard to sex attractants and/or pheromones already known for these families. Zusammenfassung Neue Sexuallockstoffe für männliche Lepidopteren (Coleophoridae, Gelechiidae, Momphidae, Oecorophoridae, und Yponomeutidae), entdeckt bei Freilandprüfungen in den Niederlanden Durch Untersuchung von 48 einfach‐ungesättigten Alkenylacetaten mit Kettenlängen von 10, 12, 13, 14 und 16 Kohlenstoffatomen einzeln oder in Mischungen von 2 Stoffen sind Sexuallockstoffe für 14 Arten von Lepidopteren entdeckt worden: Coleophora frischella, C. vacciniella (Coleophoridae), Brachmia blandella, B. inornatella, Bryotropha galbanella, B. senectella, Chionodes electella, Gelechia sororculella, Monochroa tenebrella, Sophronia semicostella (Gelechiidae), Batrachedra pinicolella (Momphidae), Bisigna procerella, Pseudatemelia spp. (Oecophoridae), und Ocnerostoma friesei (Yponomeutidae). Die Ergebnisse werden in bezug auf Sexuallockstoffe bzw. Sexualpheromone, welche für diese Familien schon bekannt sind, kurz diskutiert.

Sex pheromone of the red clover casebearer moth, Coleophora deauratella, an invasive pest of clover in Canada

“…Coleophora deauratella is one of minimally eleven Coleophora species in the frischella group which is Palearctic in distribution (Landry & Wright, 1993). Within this group, sex pheromone chemistry is poorly known and sex attractants for only two species, C. mayrella (Priesner, 1987) and Coleophora frischella (Willemse et al., 1987), have been elucidated. Coleophora frischella males are attracted to a 1:1 ratio of Z 7‐12:OAc and Z 5‐12:OAc in The Netherlands (Willemse et al., 1987); the same pheromone components isolated from female C. deauratella gland extracts in this study.…”

Coleophora deauratella and two other members of the frischella group, C. mayrella and C. trifolii , are pests of different species of clover (red and alsike, white and sweet clover, respectively) seeds and occur sympatrically in both their native and introduced ranges (Landry & Wright, 1993).…”

New sex attractants and inhibitors for 17 moth species from the families Gracillariidae, Tortricidae, Yponomeutidae, Oecophoridae, Pyralidae and Gelechiidae

“…Admixture of the other acetate is necessary, either E9-, Z10-or E10-14:OAc. WILLEMSE et al (1987) have reported (@-9-tridecenyl acetate (E9-13:OAc) to be a sex attractant for males of B. galbanellu. Z9a n d E9-14:OAc are known to be attractive for three other species of the family Gelechiidae, B. senectella Z.…”

A mono‐unsaturated acetate as sex attractant for the leaf miner moth Lithocolletis corylifoliella (Hübner) (Lep., Gracillariidae)

“…Vials containing the experimental odorants were hung in the top of delta traps with a sticky bottom S. Voerman of 10 x 17 cm ( WILLEMSE et al 1987). In 1990 these traps were transparent and colorless, while in the years before they were white opaque.…”

“…While in a field screening experiment in 1985 the mono-unsaturated compound (E)-4dodecen-1-01 acetate (E4-12:Ac) also appeared to be attractive for this species, the relative attractancy of E4-12:Ac and EZ4,7-13:Ac were not compared ( WILLEMSE et al 1987). In 1986, 1987, and 1990 the value of E4-12:Ac as a simple sex attractant for L. corylifoliella was tested in more detail and in competition with EZ4,7-13:Ac in a dune area and an apple orchard in The Netherlands.…”
