Primi reperti in Sicilia su diffusione e biologia di Leptoglossus occidentalis Heidemann (Hetroptera: Coreidae), cimice americana dei semi delle coni…
2009
In this paper the first data on the distribution and biology of L. occidentalis in Sicily are reported; this bug, belonging to the family Coreidae, originates from North America, where it is regarded as a serious pest of conifer seed orchards. The first Sicilian specimens of L. occidentalis were found in September 2002 near Gangi (PA), while the first collecting data published until now refer to November 2003 in Niscemi (CL). The coreid is distributed in all Sicily provinces (30 collecting sites), from the sea level to 1.430 m a.s.l. on the mountains; it was collected on cones and plants of Pinus halepensis Miller, P. laricio Poiret, P. pinea L., P. nigra J.F.Arnold and Pseudotsuga menziesi…
Introduction into Italy of Gryon pennsylvanicum (Ashmead), an egg parasitoid of the alien invasive bug Leptoglossus occidentalis Heidemann
2011
Leptoglossus occidentalis (Heteroptera, Coreidae), a Nearctic species, was accidentally introduced into Northern Italy in the late 1990s, from where it has spread throughout Europe. The bug causes abortion of immature cones of Pinus pinea L., with economic impact on the pine-nut industry. As part of a pest control research program, the egg parasitoid Gryon pennsylvanicum Ashmead (Hymenoptera, Platygastridae) was collected from British Columbia, Canada, and legally introduced to a quarantine climatic chamber in Florence, Italy. The egg parasitoid will be tested against native non target heteropterans, an environmental impact assessment will be conducted, and a mass rearing method will be dev…
