Abstract
Cunaxa capreolus Berlese failed to develop on diets of plant material but developed equally well on diets of booklice (Psocoptera) or of the citrus brown mite,Eutetranychus orientalis (Klein), which were eaten in their active stages and not as eggs. Cannibalism occurred during shortage of food. Although the growth of the immature stages ofC. capreolus was accompanied by an increasing consumption of prey, yet their total consumption was less than 30% of that of the female adult. The number of prey individuals consumed byC. capreolus was inversely related to temperature but consumption rate increased slightly with increasing temperature.
Résumé
Cunaxa capreolus Berlese ne se développe pas à partir de matières végétales tandis que lui convient également bien une alimentation à base de psoques ou de l'acarien des citrus,Eutetranychus orientalis (Klein), qui sont consommés à l'état de stades mobiles mais non d'œufs. En cas de manque de nourriture, du cannibalisme se manifeste. Au cours de l'évolution des stades immatures deC. capreolus il y a une augmentation de la consommation des proies, mais la consommation totale de ces stades est inférieure à 30% de celle des femelles adultes. Le nombre de proies dévorées est en rapport inverse avec la température, mais le taux journalier de consommation augmente lentement avec celle-ci.
