A new species of Nowicki (Hymenoptera: Trichogrammatidae) from Italy.

A new species of Soikiella Nowicki (Hymenoptera: Trichogrammatidae) that emerged mostly from galls induced by Dryocosmus kuriphilus Yasumatsu (Hymenoptera: Cynipidae) on chestnut is described from Italy. The characterization of the new taxon, Soikiella italica Viggiani sp. n.

Fine Structure of Antennal Sensilla of Paysandisia archon and Electrophysiological Responses to Volatile Compounds Associated with Host Palms.

Paysandisia archon (Lepidoptera: Castniidae) is a serious pest of palm trees. A comprehensive knowledge of the insect olfactory system is essential for the development of efficient semiochemical-based control methods. The olfactory sensilla are located particularly on the antennae, and these can detect plant volatiles that provide important cues for the insects in the search for their host plants.
