Abstract

Field-collected Agonum muelleri (Herbst) adults were videotaped to assess their ability to climb soybean (Glycine max (L.) Merr. (Fabaceae)) plants. All individuals climbed up and down soybean plants multiple times. Agonum muelleri spent from 12.5 ± 3.4% to 54.1 ± 11.3% of their time on soybean plants. Caged A. muelleri adults on plants infested with soybean aphids, Aphis glycines Matsumura (Hemiptera: Aphididae), reduced the number of apterous adults. The presence of predators had an indirect effect on the density of nymphal aphids by reducing the numbers of adult aphids. Agonum muelleri, an abundant carabid in soybean fields, readily climbs soybean plants to feed on soybean aphids.

Résumé

Nous avons fait des enregistrements vidéo d’adultes d’Agonum muelleri (Herbst) prélevés en nature afin d’évaluer leur capacité à grimper le long de plants de soja (Glycine max (L.) Merr. (Fabaceae)). Tous les individus se sont déplacés de nombreuses fois vers le haut et le bas sur les plants de soja. Les A. muelleri passent de 12,5 ± 3,4 % à 54,1 ± 11,3 % de leur temps sur les plants de soja. Des A. muelleri en cages placés sur des plants de soja infestés par le puceron du soja, Aphis glycines Matsumura (Hemiptera: Aphididae), réduisent le nombre d’adultes aptères. La présence de prédateurs a un effet indirect sur la densité des larves de pucerons, en réduisant le nombre de pucerons adultes. Agonum muelleri, un carabe commun dans les champs de soja, grimpe volontiers sur les plants de soja pour se nourrir des pucerons du soja.
