Vu, Q.K. 1974 Morphological and biological characteristics of the immature stages of Encyrtus infidus Rossi (Hymenoptera Chalcidoidea) -- a parasite of the caragana scale (Eulecanium caraganae Borchs.).. Entomological Review 53(4): 8-21.
Notes: Under conditions of the Leningrad region, two generations of E. infidus develop in a year to one generation of E. caraganae. The larvae of the parasite in the 1st-2nd instars overwinter in the 1st-2nd instar larvae of the host. Previously Encyrtus infidus was known as a parasite of Eulecanium douglasi and E. franconicum.
