RESPONSES OF PROSTEPHANUS TRUNCATUS TO COMPONENTS OF THE AGGREGATION PHEROMONE OF RHYZOPERTHA DOMINICA IN THE LABORATORY AND FIELD

Abstract

Laboratory and field studies have been made of the responses of Prostephanus truncatus (Horn) to two components of the aggregation pheromone of Rhyzopertha dominica (Fabricius) — (±)‐1‐methylbutyl (E)‐2‐methyl‐2‐pentenoate and (±)‐1‐methylbutyl (E)‐2,4‐dimethyl‐2‐pentenoate, known as “Dominicalure 1” and “Dominicalure 2” respectively. In the laboratory, these compounds were tested individually and as a 1:2 mixture; P. truncatus responded most strongly to Dominicalure 2 alone.All three treatments were compared in a field trial in Tanzania to monitor both R. dominica and P. truncatus in farm stores. Dominicalure 1 or a mixture of 1 and 2 were both highly effective for trapping R. dominica. In contrast, Dominicalure 2 trapped more P. truncatus than the other treatments and was about as effective as visual inspection at demonstrating the presence of the beetle in stores. Dominicalure 2 could form the basis of a monitoring programme for P. truncatus in East Africa.RÉSUMÉRéponses au laboratoire et dans les champs de Prostephanus truncatus aux constituants de la pheromone d'agrégation de Rhyzopertha dominicaLes réponses de Prostephanus truncatus Horn (Coleoptera: Bostrichidae) à deux constituants de la pheromone d'agrégation de Rhyzopertha dominica Fabricius (Coleoptera: Bostrichidae), le (±)‐1‐méthylbutyl (E)‐2‐méthyl‐2‐penténoate et le (±)‐1‐méthylbutyl (E)‐2,4‐diméthyl‐2‐penténoate, connus comme “Dominicalure 1” et “Dominicalure 2”, ont été étudiées au laboratoire et au champ. Au laboratoire ces composés ont été essayés individuellement et en mélange 1:2. Une membrane de caoutchouc imprégnée de pheromone a été utilisée comme émetteur lent, et une courbe de réponse en fonction de la dose a été établie. P. truncatus répondait plus vigoureusement à la Dominicalure 2 seule.Tous ces traitements ont été comparés dans un essai aux champs en Tanzanie, dans lesquels des pièges en carton ondulé contenant des diffuseurs de pheromone étaient placés dans des entrepôts de maïs dans les fermes. La Dominicalure 1 et le mélange de 1 et 2 étaient tous deux efficaces pour piéger R. dominica. La Dominicalure 2 a piégé plus de P. truncatus que les autres traitements et était à peu près aussi efficace que le contrôle visuel pour détecter la présence de cet insecte dans les stocks. On peut envisager que la Dominicalure 2 pourrait servir de base à un programme pour lutter contre P. truncatus en Afrique de l'Est.
