Gas chromatography and mass spectrometry analyses of crude sex pheromone gland extracts revealed that virgin Synanthedon tipuliformis (Clerck), currant borer (Lepidoptera: Sesiidae) females, produced 6 compounds, structurally related to sex pheromone components of clearwing moths. By comparison of retention times and mass spectra of natural products with corresponding properties of synthetic standards, these compounds were identified as: (2E,13Z)-octadeca-2,13-dien-1-yl acetate (E2,Z13-18:OAc), (3E,13Z)-octadeca-3,13-dien-1-yl acetate (E3,Z13-18:OAc), (13Z)-octadec-13-en-1-yl acetate (Z13-18:OAc), (2E,13Z)-octadeca- 2,13-dien-1-ol (E2,Z13-18:OH), (13Z)-octadec-13-en-1-ol (Z13-18:OH) and octadecan- 1-ol (18:OH) in the ratio 100:0.7:2.7:3.2:traces:traces. The first 3 compounds were previously known to occur in the sex pheromone gland extracts of currant borers, while the last 3 chemicals are now reported for the first time. Trapping tests carried out in the black currant field revealed that E2,Z13-18:OAc, when tested separately, attracted S. tipuliformis males, while addition of E3,Z13-18:OAc to the main component increased the effectiveness of E2,Z13-18:OAc over seven times. The attractiveness of 6 component lures did not differ significantly from the one of the binary mixture, confirming that E2,Z13-18:OAc and E3,Z13- 18:OAc in the ratio100:0.7 are essential sex pheromone components of S. tipuliformis. Trapping tests carried out at the dwelling place of Synanthedon scoliaeformis (Borkhausen) (Lepidoptera: Sesiidae) revealed that, in addition to intraspecific synergistic effect, E3,Z13-18:OAc increased the specificity of the pheromone signal of S. tipuliformis, acting by intraspecific mode as an attraction antagonist against S. scoliaeformis males. By this way, it ensured the specificity of the sex attraction signal of the currant borer. Consequently, both compounds E2,Z13-18:OAc and E3,Z13-18:OAc have to be present in pheromone formulations used for monitoring and/or control of S. tipuliformis to avoid effecting non-target species. Other compounds identified from the sex pheromone gland of S. tipuliformis did not show any significant interspecific activity for males of S. scoliaeformis, however, they provide a basis to achieve specificity of a pheromone signal of S. tipuliformis and could act as attraction antagonists against other clearwing moth species which, like S. tipuliformis, employ E2,Z13- 18:OAc as their sex pheromone component.

AbstractUsing gas chromatography and gas chromatography – mass spectrometry analyses of sex pheromone gland volatiles, we identified E- and Z-11-tetradecenals (E:Z-11-14:Aid) in an 85:15 blend of E:Z as the primary sex pheromone components of Croesia semipurpurana (Kearfott). Similar chemical analyses of sex pheromone gland extracts indicated the presence of the congeneric acetates (85:15 E:Z-11-14:Ac) and their saturated analogue (14:Ac); in addition, 85:15 E:Z-11-14:Alds were present at 5% of the acetates. The E:Z-11-14:Alds alone elicited trap capture; admixtures of saturated and unsaturated acetate analogues exhibited no significant synergistic or inhibitory effects. PVC rods with an 85:15 E:Z-11-14:Ald blend is recommended as a trap bait for monitoring population trends. It is unknown whether or not the components identified here represent the complete pheromone blend of this species; data from traps suspended 1.5 m above the ground versus those suspended 10 m above the ground suggest that future field studies may need to be conducted with traps positioned in the tree canopy.

Natural Pheromone

Z-7-Dodecenyl acetate and Z-7-dodecenyl alcohol have been identified as sex pheromone components o f female Autographa gamma. This is the first time that Z-7-dodecenyl alcohol has been found in the natural pheromone of Plusiinae. When incorporated in pherom one traps of some Plusiinae species the alcohol is both synergist and inhibitor, thus being an important factor in sex isolation among sympatric Plusiinae species in Israel

Paranthrene Tabaniformis

A chemical analysis of the crude sex pheromone gland extracts of virgin calling Paranthrene tabaniformis females, obtained from the European part of Kazakhstan, revealed the presence of five compounds: (3E,13Z)-octadeca-3,13-dien-1-ol (E3,Z13-18:OH), (3Z,13Z)- octadeca-3,13-dien-1-ol (Z3,Z13-18:OH), (2E,13Z)-octadeca-2,13-dien-1-ol (E2,Z13-18:OH), (13Z)-octadec-13-en-1-ol (Z13-18:OH), and octadecan-1-ol (18:OH) at the ratios 64.0 : 32.4 : 1.4 : 0.9 :1.3, which are structurally related to sex pheromone components of clearwing moths. Our previous field tests showed synergistic effects of Z3,Z13-18:OH and E2,Z13-18:OH to attract P. tabaniformis males, when these compounds were tested in binary mixtures with the known sex pheromone E3,Z13-18:OH. The three dienic alcohols should all be considered as sex pheromone components of the P. tabaniformis species, while the role of Z13-18:OH and 18:OH remained unclear.

The New Zealand native moth Tmetolophota atristriga (Walker) (Lepidoptera Noctuidae) is a background pest defoliating pasture This project identified the pheromone components of the female pink grass worm that could be used to trap male moths in a control or monitoring programme Extraction of the sex pheromone gland of virgin female moths and GCMS analysis has identified several compounds in the sex pheromone gland two monounsaturated compounds cis11hexadecenal (Z1116Ald) and cis11hexadecyl acetate (Z1116Ac) and three saturated compounds hexadecan1ol (16OH) hexadecyl acetate (16Ac) and octadecan1ol (18OH) and triene hydrocarbon (ZZZ)369tricosatriene (Z3Z6Z923Hy) A field trapping experiment was conducted using binary blends of the two main compounds Z1116Ald and Z1116Ac at five different ratios (ie 1000 7525 5050 2575 and 0100) The highest catch was obtained at ratio 2575 of Z1116AldZ1116Ac; males were also caught at the 5050 ratio No catches were recorded with any other ratio tested A dose response experiment was conducted testing five loadings of the optimum binary (2575 ratio) mixture (01 1 10 100 and 1000 mg loading) and males were caught only at 01 and 1 mg loadings In a field trapping experiment conducted late in the season (2008) using the three additional minor compounds only the addition of Z3Z6Z923Hy to the binary mixture significantly enhanced male attraction

Fourteen and 16 carbon saturated and monounsaturated aldehydes have been identified as sex pheromone components for the four. species of Heliothis studied to date (Nesbitt et al. 1979; Klun et al. 1979; Teal et al. 1981). With the exception of H. zea (Boddie), the alcohol corresponding to the major aldehyde component, (Z)-1 l-hexadecen- 1-ol (Zl l-16:OH), also has been found in pheromone gland extracts of all species. We report here the identification of Zll-16:OH from pheromone gland extracts of H. zea females and the results of field trapping studies used to assess the behavioral effects of this compound on conspecific males.
