Contribution a l'etude des interactions hote-parasite chez coccus hesperidum L [Hom Coccidae] et son parasite coccophagus scutellaris dalman [Hym Aphelinidae]

ABSTRACT

Intensity of egg laying of Coccophagus scutellaris depends on the number of hosts available. It is found to be more important when the female has severall hosts. Furthermore a better distribution of eggs is observed in that case. When parasited and umparasited hosts are available, the female of Coccophagus deposits more eggs on the latter. This discriminating ability in relation to number and kinds of hosts available is discussed
