Dusky wireworms, Agriotes obscurus (L.), aggregated in similar numbers at wheat [Triticum aestivum L. (Gramineae) ‘Max’], oat [Avena sativa L. (Gramineae) ‘Walderen’], barley [Hordeum vulgare L. (Gramineae) ‘Verdin’], and fall rye [Secale cereale L. (Gramineae) ‘Wheeler’ and ‘Prima’] cultivar bait stations containing 100 seeds planted 3 cm deep in 127-cm2 circular bait stations. Similar levels of aggregation also occurred at 11 varieties of wheat planted at 100 seeds/127 cm2. When wheat, oat, barley, and the fall rye cultivars were planted at increasing density (0–180 seeds per bait station), aggregation by A. obscurus increased initially, but reached a plateau at numbers and at seeding rates specific to each grain variety as determined using the asymptotic equation y = B0(1 – eB1x). Except for barley, this equation predicted wireworm densities within 11% of the densities actually observed at bait stations with 100 seeds/127 cm2. It was concluded that any of the wheat, oat, barley, or fall rye varieties would be suitable for monitoring A. obscurus wireworm populations if planted in bait stations at 100 seeds/127 cm2, as well as for aggregating wireworms by means of a trap crop.


Les taupins obscurs, Agriotes obscurus (L.), se rassemblent en nombres semblables à des zones d'appâts garnies de blé [Triticum aestivum (Gramineae) ‘Max’], d'avoine [Avena sativa L. (Gramineae) ‘Walderen’], d'orge [Hordeum vulgare L. (Gramineae) ‘Verdin’] ou de seigle d'automne [Secale cereale L. (Gramineae) ‘Wheeler’ et ‘Prima’], où nous avons semé 100 graines à 3 cm de pro fondeur dans des enceintes circulaires de 127 cm2. Des rassemblements semblables se sont produits en présence de 11 variétés de blé plantées à raison de 100 graines/127 cm2. Lorsque les cultivars de blé, d'avoine, d'orge et de seigle d'automne sont plantés à des densités croissantes (0–180 graines par zone), les rassemblements d'A. obscurus augmentent au début, mais atteignent un plateau à des nombres et à des taux de semis spécifiques à chaque variété de graine déterminés selon l'équation de l'asymptote y = B0(1 – eB1x). Sauf dans le cas de l'orge, cette équation a permis de prédire la densité des taupins avec un écart de moins de 11 % de la densité réelle observée dans des zones d'appâts à taux de semis de 100 graines/127 cm2. Il semble donc que n'importe laquelle des variétés de blé, d'avoine, d'orge ou de seigle d'automne puisse convenir pour suivre les populations de taupins obscurs si elle est plantée dans des zones d'appâts à raison de 100 graines/127 cm2; la même plante peut servir de plante piège pour rassembler les taupins.
