“…Ctenopseustis obliquana (Walker), the brownheaded leafroller, was found to use a combination of Z5-14" OAc and Z8-14:OAc (Young et al, 1985), and the P. excessana "species" from the central North Island apparently uses a combination of Z5-14 : OAc and Z7-14 : OAc . Z5-14 : OAc also has been reported to be a sex pheromone component of a cossid moth (Capizzi et al, 1983) and a noctuid moth (Bestmann et al, 1980), and as part of an attractant blend for several other noctuid moth species (Steck et al, 1982). Since the compounds found in the New Zealand leafroller species are uncommon in other Tortricidae (Roelofs and Brown, 1982), further studies on the sex pheromone of other related New Zealand leafroller populations and the biosynthetic pathways used in these primitive species should provide valuable information on evolutionary relationships within the genus Planotortrix and between other genera in the tribe Archipini.…”

(Z)-5-Tetradecenyl acetate and tetradecyl acetate were identified as sex pheromone components of an unnamedPlanotortrix leafroller moth species found onAvicennia resinifera (mangrove). An equal mixture of the two compounds used as bait gave field trap catches at least as good as those baited with caged virgin females. Traps baited with the two chemicals caught malePlanotortrix moths in a mangrove swamp not previously found to host the unnamedPlanotortrix species. Adults of the unnamedPlanotortrix species and of the greenheaded leafroller,Planotortrix excessana are morphologically indistinguishable. The sex pheromone ofP. excessana has been found previously to be a mixture of (Z)-S-tetradecenyl acetate and tetradecyl acetate, and this means that the two species may now be distinguished by sex pheromone differences.

“…(Z5,E7)-12:OH was the only component common for all Dendrolimus species. (Z5)-14:OAc occurred in the sex pheromone of several moths: the Cossidae family [51], heart and dart moth Scotia exclamationis L. (Lepidoptera, Noctuidae) [52], and army cutworm moth Euxoa auxiliaris (Grote) (Lepidoptera, Noctuidae) [53]. (Z5)-10:OAc was the major component of the sex pheromone of the turnip moth Agrotis segetum (Den.…”

The pine-tree lappet moth, D. pini, is a harmful defoliator of pine forests in Europe and Asia and a potentially invasive species in North America. The lures for trapping D. pini males based on two known components of its sex pheromone appeared weakly attractive to male moths. Identification of all components of the sex pheromone might allow for the development of more effective lures. The pheromone was sampled from virgin females using SPME and analyzed using gas chromatography coupled with mass spectrometry. Four new likely components ((Z5)-dodecenal, (Z5)-dodecen-1-ol, (Z5)-decen-1-yl acetate, (Z5)-tetradecen-1-yl acetate) and two known components ((Z5,E7)-dodecadienal, (Z5,E7)-dodecadien-1-ol) were identified based on comparison against authentic standards, Kováts indices and spectra libraries. The samples also contained several sesquiterpenes. Wind tunnel and field experiments showed that some blends of synthetic pheromone components alone or enriched with Scots pine essential oil (SPEO) were attractive to D. pini males. One component—(Z5)-decen-1-yl acetate—had a repelling effect. The presented knowledge of D. pini sex pheromone provides a basis for developing optimal lures for monitoring or controlling insect populations.

“…divisella ) is a more common pheromone of a relatively broad range of lepidopterans, including several closely related Ctenopseustis and Planotortrix spp. (both Tortricidae) endemic to New Zealand (for a recent review see Newcomb et al., ), the European goat moth, Cossus cossus L. (Crossidae) (Capizzi et al., ), and the heart and dart moth, Agrotis exclamationis L. (Noctuidae) (Bestmann et al., ).…”

Sex pheromone of the iris gelechiid moth Monochroa divisella

The iris gelechiid moth, Monochroa divisella (Douglas) (Lepidoptera: Gelechiidae), is a serious pest in iris horticulture. The overuse of pesticides for conventional control has a great risk of water pollution because irises are often planted in damp areas. To minimize pesticide applications, it is essential to monitor moth emergence by using pheromone traps. The female pheromone of M. divisella was analyzed by means of gas chromatography‐electroantennographic detection (GC‐EAD) and GC‐mass spectrometry. Two male EAD‐active compounds were detected and identified as (Z)‐3‐dodecenyl acetate (Z3‐12:Ac) and (Z)‐5‐tetradecenyl acetate (Z5‐14:Ac), the amounts of which were ca. 40 and 6 ng per female (100:15), respectively. Synthetic Z3‐12:Ac alone attracted only a few males in field trap experiments, but the attractiveness was significantly enhanced when 15% (wt/wt) Z5‐14:Ac was added; traps baited with their binary mixtures captured 21.3‐106.4 males/trap/day, as compared with 2.3 males/trap/day attracted by a crude extract of 10 virgin females. We conclude that Z3‐12:Ac and Z5‐14:Ac are M. divisella pheromone components, which can be offered as an attractant in monitoring traps. Although dodecenyl acetates are a major class of lepidopteran pheromone components, those with the double bond at the 3 position are rare and appear to be unique to gelechiids.
