Tettigoniidae (Orthoptera) ovipositing in old galls of Dryocosmus kuriphilus (Hymenoptera: Cynipidae)
2016
Authors report some biological notes on two species of Orthoptera Tettigoniidae emerged from old spongy-woody galls of Dryocosmus kuriphilus Yasumatsu, 1951 collected in April 2015 from some areas of Sicily (Italy): Leptophyes sicula Kleukers, Odé et Fontana, 2010 (Phaneropterinae) and Cyrtaspis scutata (Charpentier, 1825) (Meconematinae). Between the end of April and the first days of May 30 neanids emerged from the galls, were reared and their cycle followed. While L. sicula laid eggs in groups, C. scutata laid single eggs inside the galls; both species have shown that in a few years they adapted in exploiting this new shelter for egg laying. No interaction with the gall inducing insect w…
New records of gall-inducer and inquiline insects in a few mediterranean countries, with biological notes
2014
An annotated list of some gall-inducing and inquiline insects found on herbaceous plants and trees in Italy and in other few Mediterranean countries is reported. Among the gall-inducer species, Phanacis phoenixopodos (Mayr, 1882) is new for the Italian peninsula, Callirhytis rufescens (Mayr, 1882), Andricus quercusramuli (L., 1761) and Plagiotrochus amenti Kieffer, 1901 (Cynipidae: Hymenoptera) are new for Sicily; the latter was previously cited from Italy without collecting data.

New records of Cynipid gall wasps and inquilines for the Italian peninsula and Sicily and their new host plants for the Palaearctic Region are listed and commented on. Among them we find: Cerroneuroterus cerrifloralis (Mullner 1901) as new for Italy and new for the Palaearctic region as host on Quercus suber; Andricus multiplicatus Giraud 1859 on Q. suber, as new host for the Palaearctic region; Aylax papaveris (Perris 1839), reported in Italy over a century ago, but later overlooked; Cerroneuroterus minutulus (Giraud 1859), also reported more than a century ago from Sicily, but later overlooked. Among the inquilines are here listed: Synergus variabilis Mayr 1872, emerged from Janetia cerri…
