[Host-parasite interactions in Coccus hesperidum L. (Hom. Coccidae) and its parasite Coccophagus scutellaris Dalman (hum. Aphelinidae). III. Effect of the number of hosts and their sanitary conditions on the oviposition of the parasite].
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 several hosts. Furthermore a better distribution of eggs is observed in that case. When parasited and parasiteless 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.
