Contribution to the knowledge of Cybocephalid beetles. Biology and ethology of Cybocephalus freyi Endrödy-Younga
Full text linkI Coleotteri Cibocefalidi sono predatori di diaspini poco studiati in Italia. Si forniscono note sulla biologia e sul ciclo di Cybocephalus freyi Endrödy-Younga, presente in Sardegna ed in Liguria.Cybocephalid beetles are predators of armored scale insects. Up to the present they have been poorly studied in Italy. In this paper we give notes on the biology and the life cycle of Cybocephalus freyi Endrödy-Younga, a species common in Sardinia and Liguria
A 3 year field survey of the natural enemies of the horse-chestnut leaf miner Cameraria ohridella in Lombardy, Italy
No full textA survey to inventory the natural enemies of the horse-chestnut leafmining moth, Cameraria ohridella Deschka and Dimic (Lepidoptera, Gracillariidae) and to evaluate their relative abundance, was conducted from 2001 through 2003 in Lombardy, northern Italy. Two predators and 10 parasitoids were found during the 3-year survey. An increasing number of parasitoid species associated with the leafminer was detected (4 species in 2001, 5 in the 2002 and 10 in 2003). Eulophidae (Hymenoptera: Chalcidoidea) were most represented: Mina tetrastichus frontalis Nees, Closterocerus trifasciatus Westwood, Pnigalio pectinicornis L., Pnigalio agraules Walker, Pediobius saulius Walker, Chrysocharis pentheus Walker, Cirrospilus talitzkii Boucek, Sympiesis sericeicornis Nees, Baryscapus nigroviolaceus (Nees). Only one Ichneurnonidae (Hymenoptera: Ichneumonoidea) was found during 2003: Itoplectis alternans (Grav.)

Indagini preliminari sui limitatori di Cameraria ohridella Deschka & Dimic (Lepidoptera Gracillariidae) in Lombardia
No full textIn cinque città della Lombardia sono stati eseguiti
campionamenti per individuare i limitatori naturali
di Cameraria ohridella Deschka & Dimic,
minatore fogliare dell’ippocastano. Il reperimento
di Imenotteri Eulofidi, già segnalati su altri fillominatori,
offre buone prospettive per il raggiungimento
di un equilibrio naturale.Preliminary surveying on the antagonists of Cameraria
ohridella Deschka & Dimic (Lepidoptera Gracillariidae)
in Lombardy.
Samplings have been executed in five towns of
Lombardy in order to characterize the natural
antagonists of Cameraria ohridella Deschka & Dimic,
the horse chestnut leafminer. The finding of
Hymenoptera Eulophidae, already recorded on
other leafminers, offers good perspectives for the
attainment of a natural balance
