Aphelinidae parasitoids [Hymenoptera: Chalcidoidea] of whiteflies [Hemiptera: Aleyrodidae] in Israel,with description of three new species

Fifteen aphelinidae species, belonging to the generaEncarsia Foerter andEretmocerus Haldeman, are recorded as new whiteflies parasitoids from Israel. Three new species are described and recorded for the first time from Israel. A key to the Israeli species is given.     

Reciprocal host-parasite relations as exemplified byChrysomphalus aonidum [Homoptera: Diaspididae] andPteroptrix smithi [Hymenoptera: Aphelinidae]

The parasitePteroptrix smithi (Compere) prefers to oviposit in hosts (Chrysomphalus aonidum L.) that are at least 5 weeks old. Parasitization of two week old hosts is possible, but only few parasites reach maturity, and the developmental duration is lengthened by about one third. The sex ratio with both large and small hosts was usually 1∶2, whereas the average number of emerging parasites varied from 1.9 for 2 week old hosts to 3–4 for 5 week old ones. Non-ovipositing scales that are attacked by the parasite will fail to reproduce and ovipositing ones will only produce part of their potential progeny. Other externally observable changes in the young parasitized host include the formation of a thinner scale cover that differs in coloration and size from the normal one.
