“…In Japan, males of four species of this genus were attracted to these single compounds or their mixtures: A. issikiella to Z11-16:Ald, A. sapporensis to 3 : 1 : 1, A. suzukiella to 1 : 9 : 0 and Acrolepiopsis sp. to 9 : 0 : 1 blends of Z11-16:Ac, Z11-16:Ald and Z11-16:OH, respectively (Ando et al, 1981), although the compounds have not been confirmed as sex pheromone components.…”

Three EAG-active components were detected in the GC-EAD analyses of the hexane extracts of abdominal tips from virgin females of Acrolepiopsis nagaimo Yasuda (Lepidoptera: Acrolepiidae). These components were identified as (Z)-11-hexadecenyl acetate (Z11-16:Ac), (Z)-11-hexadecenal (Z11-16:Ald) and (Z)-11-hexadecen-1-ol (Z11-16:OH) at 1.8, 0.6, and 0.2 ng/female, respectively, by subsequent GC-MS analyses and chemical derivatization. In a field test conducted at Daiei-cho, Tottori in 1998, more males were captured with blends of Z11-16:Ac and Z11-16:Ald (0.1 mg/septum) at ratios of 50 : 50 and 75 : 25 than with two 2-to 3-d-old virgin females while the effect of an addition of Z11-16:OH to the blends was unclear.

“…The crude material was purified by flash chromatography on silica gel (60 g) using hexane-ethyl acetate (100:8 v/v) as eluent to provide 2.31 g (8.73 mmol, 97% yield) of (9Z,12Z,-15Z)-9,12,15-octadecatrien-1-ol 2 as a colorless liquid. 1 H NMR: δ 0.99 (3H, t, J ) 7.6 Hz, CH3, C18), 1.26-1.38 (10H, m, CH2, C3-7), 1.56 (2H, quintet, J ) 7.2 Hz, CH2, C2), 1.67 (1H, br, OH), 2.03-2.12 (4H, m, CH2-Cd, C8,17), 2.80 (4H, t, J ) 6.0 Hz, dC-CH2-Cd, C11,14), 3.62 (2H, t, J ) 6.8 Hz, CH2-O, C1), 5.30-5.41 (6H, m, CHd ). 13 (11), 149 (7), 135 (15), 121 (20), 108 (49), 95 (52), 93 (50), 79 (100), 67 (60), 55 (37).…”

Facile and efficient chemical syntheses of (3Z,6Z,9Z)-3,6,9-nonadecatriene and homologues from commercially available alpha-linolenic acid [(9Z,12Z,15Z)-9,12,15-octadecatrienoic acid] are reported. These straight-chain homoconjugated trienes are common sex pheromone and attractant components for many lepidopterous insect pests. The metal-catalyzed cross-coupling reactions between (9Z,12Z,15Z)-9,12,15-octadecatrienyl triflate and the appropriate Grignard reagents proceed very rapidly under notable mild conditions using Li(2)CuCl(4) as catalyst in diethyl ether, and the resulting (3Z,6Z,9Z)-3,6,9-trienes with retention of geometrical configuration were in >92% isolated yield.

“…Probably these chemical compounds are not specific to these insect species and were present in many insect species. For example, (E)-7-dodecen-1-ol acetate was detected in Actebia fennica (Struble et al, 1989) and Grapholita endrosias (Ando et al, 1981). Heptadecanol was present in Locusta migratoria migratoriodes and Schistocerca gregaria (Ohara and Lockey, 1990).…”

Composition of volatile compounds in male and female Tenebrio molitor and Leptinotarsa decemlineata before and after the application of insecticides

Some insects can be used as food, while others can affect the destruction of crops and the reduction of food reserves. The studies described in this article showed quantitative and qualitative changes in the composition of volatile compounds contained in adult Tenebrio molitor and Leptinotarsa decemlineata insects after applying insecticides. The samples were prepared by SPME and the final determinations were carried out by GC/MS. The volatile compounds that were present only in the insects after the application of insecticides (or in a larger quantities) could be due to the insecticides, as an insect defense response to these insecticides. For example, in adult T. molitor insects, the percentage of alkanes ranged from 38.63 to 59.05% (male), and from 38.89% to 60.20 (female), depending on the insecticide used and the time elapsed since its application. In contrast, in L. decemlineata, the percentage of alkanes ranged from 43.84 to 61.85% (female), and from 42.41 to 60.11% (male). The results of the present study can be useful in understanding the i defense strategies of insects against insecticides.
