    Description / Table of Contents: Summary Extracts from the surface of eggs of the European corn borer were tested in small observation chambers and in a linear olfactometer for their effects on the searching behaviour of the egg-parasitoidTrichogramma maidis. In the observation chambers, the extracts elicited exploratory behaviour by female parasitoids with no previous oviposition experiences and increased the time the females spent in walking and drumming their antennae. Recording the position of 10 ♀♀ each minute for 15 min in 2 tubes of an olfactometer, indicated that upwind motion was significantly greater in the tube containing 10 μl of an egg extract than in the control tube containing just solvent. It is concluded that kairomones are present onO. nubilalis eggs and could act as searching incitants and short-range attractants. Preliminary GC and GC/MS analysis revealed the abundance of hydrocarbons in the extracts but the active chemicals were not characterized.
    Notes: Résumé Des extraits de la surface d'œufs de Pyrale du maïs ont été testés en microenceinte et dans un olfactomètre linéaire sur des ♀♀ deTrichogramma maidis. En microenceinte, les extraits stimulent la locomotion et le comportement exploratoire des ♀♀. En olfactomètre ils stimulent à distance la remontée des tubes vers la source. Ces résultats impliquent la présence de substances à activité kairomonale sur les œufs de Pyrale du maïs. Des analyses préliminaires des extraits ont été faites par chromatographie en phase gazeuse couplée ou non à la spectrométrie de masse et démontrent la présence de nombreux hydrocarbures.

    Notes: Abstract In Lepidoptera, reproduction is linked to chemical communication between conspecific partners. When exposed to the female sex pheromone, males respond by exhibiting typical sexual behaviour which leads to mating. Here we show that presence of the juvenile hormone producing gland (corpora allata) of the male black cutworm,Agrotis ipsilon, is necessary for pheromone responsiveness. Allatectomized males do not show any sexual behaviour, although their antennal olfactory system is functional. Allatectomized males implanted with active corpora allata recover full pheromone receptivity. It is suggested that reproductive processes are synchronized in males and females through endocrine control; timing of the mating activity could serve as an adaptive strategy linked to the migratory behaviour of this species.

    Notes: Summary Pheromonal secretions produced by females and males of the noctuid moth,Mocis megas (Guénée) have been analyzed by gas chromatography and mass spectrometry (EI (electron impact) and CI (chemical ionization)). The female sex pheromone was a blend of (Z,Z,Z) 3,6,9 heneicosatriene (55%) and (Z,Z) 3,6-cis-9S, 10R-epoxyheneicosadiene (45%). Male secretion produced at the level of a prothoracic organ was a blend of two unsaturated major hydrocarbons: (Z,Z) 6,9 heneicosadiene, (64%) and (Z,Z,Z) 3,6,9 heneicosatriene (24%) and C19, C20 and C22 homologues (total ratio 12%), as minor components. The trienic hydrocarbon was present in both sexes. The behavioral role of this male secretion has not yet been elucidated.

    Description / Table of Contents: Abstract The hexanic extracts from pheronomal glands of T. jacobaeae virgin females have been studied. Gas-chromatographic and mass-spectrometric analyses of the main component (no 1) (98%) in combination with behavioral and electrophysiological bioassays allowed us to determine its structure and absolue configuration: (Z,Z)-3,6-Cis-(S,R)9,10-epoxyheneicosadiene previously described in other Arctiid moths. A minor constituent (no 2) (1.5%) was identified as (Z,Z)-3,6-Cis-(S,R)9,10-epoxyeicosadiene by comparison with synthetic compound. This structure is a new one for a lepidoptera sex pheromone. The third component (no 3) of the same extracts has the same physico-chemical data as those of a previously reported constituent of another Arctiid moth: (Z,Z,Z)-3,6,9 heneicosatriene.
    Notes: Abstract Les analyses physico-chimiques d'extraits hexaniques de glandes à phéromone de femelles vierges de T. jacobaeae, associées à des études du comportement sexuel et à l'électroantennographie, ont permis d'identifier le composé majoritaire (98%) comme étant l'époxy-9S,10R-(Cis)-hénéicosadiène-3Z,6Z (no 1) et de déterminer sa configuration absolue. Les analogies entre les spectres du composé no 2 (1,5%) et ceux de l'époxy-9S,10R éicosadiène-3Z,6Z de synthèse nous conduisent à proposer cette structure pour ce constituant minoritaire. Le troisième produit (0,5%) possède les caractéristiques physico-chimiques de l'hénéicosatriène-3Z,6Z,9Z (no 3). Les produits 1 et 3 ont déjà été identifiés comme constituants de phéromones d'Arctiidae tandis que le produit 2 est décrit ici pour la première fois dans une sécrétion phéromonale de Lépidoptère.

    Description / Table of Contents: Summary The main component of the sex pheromone secretion produced by virgin females of A. assectella has been identified as Z-11 hexadecenal (Z11HDal) by GC analysis and mass spectrometry, EAG tests, and behavioural assays. Z11HDal elicited the highest EAG response of all C12 to C18 acetates, aldehydes, formates and alcohols tested, and induced a typical sequence of male sexual behavioural responses in olfactometer tests. In the field, traps baited with 1 mg Z11HDal on rubber septa (with 10% antioxidant) attracted male moths selectively and were competitive with virgin females. The E isomer (E 11HDal) was 104 times less attractive, whereas Z11-hexadecenyl acetate and Z11-hexadecen-1-ol, in admixture with Z11HDal strongly inhibited male responses.
    Notes: Abstract Le composant principal de la sécrétion phéromonale produite parla femelle vierge de Acrolepiopsis (Acrolepia) assectella Zell. a été identifié par chromatographie en phase gazeuse, spectrométrie de masse, tests électrophysiologiques et olfactométrie comme étant l'hexadécène-11Z al (Z11HDal). Ce composé est le plus actif en électrophysiologie parmi tous les autres acétates, alcools, aldéhydes et formiates, de C12 à C18, éprouvés sur l'antenne du mâle et il est capable de produire chez ce dernier une séquence comportementale sexuelle complète en olfactomètre à tube. Dans la nature, des capsules en caoutchouc chargées à 1 mg de Z11HDal (plus 10% d'antioxydant) attirent sélectivement les mâles et sont compétitives avec des femelles vierges. L'isomère E (E 11HDal) est environ 104 fois moins actif tandis que l'acétoxy-1 hexadécène-11Z (Z11HDA) et l'hexadécène-11Z ol-1 (Z11HDol) inhibent le pouvoir attractif du Z11HDal.
