Abstract

The effect of certain monounsaturated dodecene and tetradecene acetates and alcohols on electroantennogram (EAG) response and pheromone-mediated trap catch was examined in male obliquebanded leafroller moths, Choristoneura rosaceana (Harris) (Lepidoptera: Tortricidae). The stimulation of antennae with 0.1 ng of (Z)-11-tetradecenyl acetate (Z11-14:Ac), the major pheromone compound of this species, elicited an EAG response. The use of 1 ng of (Z)-9-tetradecenyl acetate (Z9-14:Ac) or (E)-9-tetradecenyl acetate (E9-14:Ac) or 10 ng of (Z)-9-dodecenyl acetate (Z9-12:Ac) or (E)-9-dodecenyl acetate (E9-12:Ac) was required to elicit a response. One hundred nanograms of (E)-9-tetradecenol (E9-14:OH) were required to elicit a response from antennae. The stimulation of antennae with up to 100 ng of (Z)-9-tetradecenol (Z9-14:OH) did not elicit a response. The addition of 0.1 mg of Z9-12:Ac to 1 mg of synthetic C. rosaceana pheromone consisting of a 100:2:1.5:1 blend of Z11-14:Ac, (E)-11-tetradecenyl acetate, (Z)-11-tetradecenol, and (Z)-11-tetradecenal reduced the capture of moths in pheromone-baited traps by more than 72%. Trap catch was reduced by more than 90% by the addition of 0.01 mg of Z9-14:Ac or E9-14:Ac to 1 mg of C. rosaceana pheromone. There was no detectable reduction in trap catch when 1 mg of E9-12:Ac, Z9-14:OH, or E9-14:OH was added to 1 mg of C. rosaceana pheromone. There was a greater than 95% reduction in trap catch when sources of Z9- or E9-12:Ac were mounted at the entrances to traps, 10 cm from the pheromone source. Trap catch was not affected by placing sources of Z9- or E9-14:Ac at trap entrances. Four 1 or 10 mg sources of E9-14:Ac placed 1 m from a trap did not affect the number of male C. rosaceana captured. The study demonstrates that although a compound may have profound attraction inhibiting activity when mixed directly with C. rosaceana pheromone, this activity may be lost if the inhibitor is emitted a short distance from the pheromone. The study also demonstrates that a potent attraction inhibitor such as E9-14:Ac does not repel C. rosaceana males and must be present along with pheromone to affect the behavior of this species.

Résumé

Nous avons étudié les effets de certains acétates et alcools dodécènes et tétradécènes monoinsaturés sur les résultats de l'électroantennogramme (EAG) et sur les captures aux pièges munis de phéromones chez les mâles de la tordeuse à bandes obliques, Choristoneura rosaceana (Harris) (Lepidoptera: Tortricidae). La stimulation de l'antenne à l'aide de 0,1 ng d'acétate de (Z)-11-tétradécényle (Z11-14:Ac), la composante principale de la phéromone chez cette espèce, produit une réaction à l'EAG. L'utilisation de 1 ng d'acétate de (Z)-9-tétradécényle (Z9-14:Ac) ou d'acétate de (E)-9-tétradécényle (E9-14:Ac) et de 10 ng d'acétate de (Z)-9-dodécényle (Z9-12:Ac) ou d'acétate de (E)-9-dodécényle (E9-12:Ac) est nécessaire pour provoquer une réaction. Il faut 100 ng de (E)-9-tétradécénol (E9-14:OH) pour susciter une réaction antennaire. La stimulation de l'antenne par des quantités aussi élevées que 100 ng de (Z)-9-tétradécénol (Z9-14:OH) ne provoque aucune réaction. L'addition de 0.1 mg de Z9-12:Ac à 1 mg de phéromone synthétique de C. rosaceana — composée d'un mélange dans des proportions de 100:2:1,5:1 de Z11-14:Ac, d'acétate de (E)-11-tétradécényle (E11-14:Ac), de (Z)-11-tétradécénol (Z11-14:OH) et de (Z)-11-tétradécénal (Z11-14:Al) — réduit les captures aux pièges à phéromone par plus de 72 %. L'addition de 0,01 mg de Z9-14:Ac ou de E9-14:Ac à 1 mg de phéromone réduit les captures aux pièges par plus de 90 %. Il ne se produit pas de réduction décelable des captures à l'addition de 1 mg de E9-12:Ac, de Z9-14:OH ou de E9-14:OH à 1 mg de phéromone. Si l'on place des sources de Z9- ou E9-12:Ac à l'entrée des pièges, à 10 cm de la source de phéromone, il se produit une réduction de plus de 95 % des captures au piège. Les captures au piège ne sont pas réduites par l'addition d'une source de Z9- ou E9-14:Ac à l'entrée du piège. L'installation de quatre sources de 1 ou 10 mg de E9-14:Ac à 1 m d'un piège n'affecte pas le nombre de mâles de C. rosaceana capturés. Notre étude démontre que, bien qu'un produit puisse avoir une activité élevée d'inhibition de l'attraction lorsque mêlé directement à la phéromone de C. rosaceana, cette activité peut être perdue lorsque l'inhibiteur est émis à une courte distance de la phéromone. Elle démontre aussi qu'un puissant inhibiteur de l'attraction comme E9-14:Ac ne repousse pas les mâles de C. rosaceana et qu'il doit accompagner la phéromone pour affecter le comportement de cette espèce.
