Abstract

An approach to enhance the performance of probe traps in detecting Cryptolestes ferrugineus (Stephens) adults in stored wheat is described. The repellent property of protein-enriched pea flour is exploited to increase the efficiency of the probe trap by treating the stored grain with the flour. The enhancement in performance of the traps was evaluated by placing the traps in wheat grains treated with protein-enriched pea flour at concentrations of 1%, 5%, and 10% (w/w) and observing the number of adult beetles trapped in comparison with the trap catch in untreated wheat. The traps kept in wheat treated with protein-enriched pea flour caught more beetles than traps placed in untreated wheat. The practical implications of this work are discussed with reference to sampling for C. ferrugineus.

Résumé

Une méthode simple a été développée pour augmenter la sensibilité de trappes d'échantillonnage visant à déceler les insectes adultes Cryptolestes ferrugineus (Stephens) dans du blé entreposé en utilisant des traitements avec de la farine de pois enrichie de protéines. Les propriétés répulsives de la farine de pois enrichie de protéines sont utilisées pour augmenter l'efficacité des trappes d'échantillonnage. Afin d'évaluer l'augmentation de l'efficacité des trappes d'échantillonnage, les grains de blé sont traités avec de la farine de pois enrichie de protéines à des concentrations de 1 %, 5 % et 10 % (p/p) et les échantillonnages sont comparés avec une trappe placé dans du grain non traité. Les trappes placées dans des grains traités ont capté plus de coléoptères que les trappes placées dans des grains non traités. Les conséquences de ces résultats son analysées par rapport à l'échantillonnage de C. ferrugineus.
