Résumé

Diverses proies ont été présentées aux larves d'Aeolothrips intermedius Bagnall. Les durées de développement larvaire ont servi de critère pour tester leur valeur nutritive. Les larves de thrips (Thrips tabaci Lind.,Heliothrips haemorrhoidalis Bouché etOdontothrips confusus Pr.) ont permis le développement le plus rapide (12 j en moyenne). Les acariens (Tetranychus cinnabarinus Boisd.,Tetranychus urticae Koch,Tetranychus atlanticus McGregor,Panonychus ulmi Koch,Cenopalpus pulcher Oudem.) ont donné de moins bons résultats (19 j en moyenne). Les aleurodes et les psylles n'ont pas assuré un développement complet. Quant aux aphides, ils n'ont pas été attaqués. Les adultes deA. intermedius doivent consommer des tissus floraux pour parvenir à la maturité sexuelle. A défaut de proies une alimentation florale peut aboutir au développement complet du prédateur. Des études quantitatives ont confirmé les résultats obtenus. Il semble donc qu'A. intermedius soit surtout un prédateur de thrips mais qu'il puisse aussi se nourrir d'acariens.

Summary

Various species of preys were given to the larvae ofAeolothrips intermedius Bagnall. Duration of larval development was used to gauge their nutritive value. Larvae of thrips (Thrips tabaci Lind.,Heliothrips haemorrhoidalis Bouché, andOdontothrips confusus Pr.) allowed the fastest development (12 days/average). (Tetranychus cinnabarinus Boisd.,Tetranychus urticae Koch,Tetranychus atlanticus McGregor,Panonychus ulmi Koch,Cenopalpus pulcher Oudem.) gave less good results (19 days/average). Aleyrodids and psyllids did not allow full grown. As for the aphids, they are not preyed. Adults ofA. intermedius need to feed on flowers to reach sexual maturity., In the absence of prey a floral diet can give full larval growth in predator.

Quantitatives studies confirm these results. It seems thatA. intermedius is chiefly a predator of thrips but it can also prey on acari.
