The oak gall wasps of Israel (Hymenoptera, Cynipidae, Cynipini) - diversity, distribution and life history Author Shachar, Einat Author Melika, George Author Inbar, Moshe Author Dorchin, Netta text Zootaxa 2018 2018-11-16 4521 4 451 498 journal article 27950 10.11646/zootaxa.4521.4.1 832ac35c-8871-4041-9321-ea7f2ae5eb41 1175-5326 2610021 A4FD6137-25B0-43D5-845B-B4FDF4E9F5D7 Andricus multiplicatus Giraud, 1859 Host plants. Israel : Q. libani . Elsewhere: Q. brantii , Q. cerris , Q. trojana . Life history. Known only from the bud galls of the sexual generation, which are multi-chambered, often aggregated leafy rosettes, 25–40 mm in diameter, with numerous larval chambers at the bases of the rosette leaves ( Fig. 67 ). Old galls remain on the tree for a year. Phenology. Galls begin to develop in May, at which time the rosette is bright green. Adults emerge from them in June, after which the gall turns brown and dries out. Distribution. Israel : Mt. Hermon, 1780 m .a.s.l. Eleswhere: common from South-central Europe to Turkey . Comments. This gall resembles that of A. cydoniae Giraud , which is unknown from Israel and develops on the same oak hosts. However, the galls of A. cydoniae are genuinely multi-chambered, with many larval chambers inside a single solid mass of tissue, rather than an aggregation of distinct galls. In Europe, A. multiplicatus is known from Q. cerris but we did not find it on this host plant in Israel . The morphology of the galls on the different host plants in Iran and Europe is similar to that of the Israeli galls on Q. libani .
