Abstract Evidence obtained by glass capillary gas chromatography coupled to an electroantennographic detector or a mass spectrometer confirmed that Z-11-hexadecenyl acetate is the major component in the pheromone gland washes of calling Mamestra brassicae female moths. Three other components were identified, tetradecanyl acetate, hexadecanyl acetate and E-11-hexadecenyl acetate; but none of these had obvious synergistic effects in attracting males in field tests. The attraction of males to Z -11-hexadecenyl acetate was inhibited by 0.1% Z -11-hexadecenol or 1% Z-9- tetradecenyl acetate.

Main Component

In electroantennographic studies on Tortrix viridana ma­les, (E)-11-tridecenyl acetate displayed the highest activity of all straight-chain alkenyl acetates. However, evidence obtained by gas chromatography coupled to an electroan­tennographic detector or a mass spectrometer indicated that the ubiquitous pheromone compound (Z)-11-tetrade- cenyl acetate is the main component in the T. viridana fe­male secretion. This compound and both (Z)- and (E)-11- tridecenyl acetate were found to be attractants for T. viridana males in the field. (Z)-9- and (E)-11-tetradecenyl acetate were not attractive and reduced male catches when added to either (Z)-11-tetradecenyl acetate or (E)-11-tridecenyl acetate. No evidence for synergistic effects was obtained.

AbstractZ8-tetradecenyl acetate (Z8-14OAc andZ8-tetradecenyl alcohol (Z8-14OH) were identified as sex pheromone components of the eyespotted bud moth, Spilonota ocellana (Denis and Schiffermüller) (Lepidoptera: Olethreutidae). Compounds were identified by gas chrornatographic-eleclroantennographic (GC-EAD) and GC-mass spectroscopic analyses and field tested in apple orchards in the Okanagan Valley, B.C. Although Z8-14OAc alone was attractive to male S. ocellana, the addition of 1–5% Z8-14OH strongly synergized its attraction. Field tests comparing the attractiveness of virgin female S. ocellana with various doses of a 99:1 blend of Z8-14OAc and Z8-14OH indicated the natural sex pheromone has only two significant components. A 99:1 blend of Z8-14OAC and Z8-14OH is suggested for monitoring and control of S. ocellana populations in British Columbia.

AbstractPheromone gland rinses of female maple leaf roller moths were analyzed by capillary gas chromatography and found to contain (Z)-11-tetradecenal, (E)-11-tetradecenal, tetradecanal, (Z)-11-tetradecenyl acetate, (E)-11-tetradecenyl acetate, and tetradecyl acetate in the average ratio of 33:20:8:21:17:2 for single female analysis and 31:16:6:16:27:3 for a pooled extract of 55 females. Identity of the tetradecenals, the tetradecenyl and tetradecyl acetates was confirmed by gas chromatography/mass spectrometry. Electroantennogram analysis indicated that (Z)-11-tetradecenal followed by (E)-11-tetradecenal were the most stimulating compounds tested. In field tests, only three components (Z)-11-tetradecenal, (E)-11-tetradecenal and (Z)-11-tetradecenyl acetate, in the microgram ratio of 65:35:10, were necessary for optimum attraction. Another tortricid moth, Archips griseus, was attracted to some of the aldehyde mixtures.

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.

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.

Aim: Identification and characterization of female released sex pheromone components of jute semilooper, Anomis sabulifera Guenee (Lepidoptera: Noctuidae) from female pheromone gland extracts. Methodology: Electroantennogram (EAG) was carried for studying the antennal response; Gas Chromatography coupled with Electro antenna Detector (GC-EAD) was conducted for studying the antennal response of eluted compounds from female pheromone gland extract; Gas Chromatography and Mas Spectrophotometry (GC-MS) was conducted for characterization or getting complete profile of compounds present in the female pheromone gland extract based on retention times. Wind tunnel assay was conducted for studying the behavioural responses of eluted compounds from the female pheromone gland extract. Results: GC-MS profile of female pheromone gland extract revealed that the GC-EAD active region constituted (6Z,9Z)-heneicosadiene, (3Z,6Z,9Z)-heneicosatriene as active compounds. Preliminary wind tunnel studies for olfactory and behavioural responses showed blend of (6Z,9Z)-heneicosadiene (3 parts) + (3Z,6Z,9Z)-heneicosatriene (1 part) enticed 60% male adults. Interpretation: (6Z,9Z)-heneicosadiene and (3Z,6Z,9Z)-heneicosatriene are likely to be active pheromone components present in female sex pheromone glands. Blending of these two compounds in precise ratio can enhance the effectiveness of pheromone and can be used as effective strategy in jute IPM. Key words: Anomis sabulifera, Jute semilooper, Noctuidae, Sex pheromone, (6Z,9Z)-heneicosadiene, (3Z,6Z,9Z)-heneicosatriene

By means of thin-layer chromatography (TLC), electroantennogram (EAG), gas chromatography (GC), gas chromatography-mass spectrometry (GC-MS) and field tests, (Z)-3-tetradecenyl acetate(Z3-14:Ac), (E)-3-tetradecen-1-ol(E3-14:OH), and (Z)-3-tetradecen-1-ol(Z3- 14:OH) at a ratio of 51:39:10 were identified from the female sex pheromone gland extracts of the carpenterworm, Holcocerus insularis Staudinger (Lepidoptera, Cossidae). The average amounts of Z3-14:Ac, E3-14:OH and Z3-14:OH in a single sex pheromone gland of calling moth were 7.29±2.72 ng, 5.72±2.43 ng and 1.44±0.56 ng, respectively. This is the first time that Z3-14:Ac was identified as a component of lepidopteran sex pheromone. Traps baited with rubber septa impregnated with Z3-14:Ac (500 μg / septum) were more effective than the traps baited with virgin female. The addition of the E3-14:OH and Z3-14:OH to rubber septa baited with Z3-14:Ac did not modify H. insularius male attraction, but E3-14:Ac slightly enhanced trap catch.
