Abstract
When the efficacy of the predaceous bugXylocoris flavipes (Reuter) was tested in the laboratory as a biological control agent against stored-product insects, it attacked eggs more than larvae, pupae, or adults and early-stage larvae ofTribolium castaneum (Herbst) more than late-stage larvae. The predator also killed more larvae ofT. castaneum than larvae ofAttagenus megatoma (F.). The density of predator and prey regulated the capture rate of the predator. Predation byX. flavipes was uninfluenced by starvation for as much as 96 hr.
Résumé
En laboratoire, le prédateurXylocoris flavipes (Reuter) s'alimente davantage aux dépens des œufs que des larves, des nymphes et des imagos et aux dépens des trois premiers stades larvaires deTribolium castaneum (Herbst) de préférence aux derniers stades. Le prédateur préfère les larves deT. castaneum à celles deAttagenus megatoma (F.). La densité de prédateurs et de proies détermine le taux de capture par le prédateur. La prédation parX. flavipes n'est pas influencée par unjeûne de 96 heures.
