New insights into the distribution and spreading of the Asian walnut moth, (Erschov, 1874) (Lepidoptera, Nolidae) in Europe with a focus on the Italian range.

The Asian walnut moth, (Erschov, 1874) (Lepidoptera, Nolidae) is an alien pest originating from Central Asia and is now spreading in Europe, attacking walnut trees. In this study, we updated the current distribution of , focusing on the Italian range, where it was reported for the first time in 2021. Field surveys showed an extensive distribution of in northern Italy, particularly in the Veneto Region.

Aphids Facing Their Parasitoids: A First Look at How Chemical Signals May Make Higher Densities of the Pea Aphid Less Attractive to the Parasitoid .

Herbivore-induced plant volatiles constitute the first indicators of insect host presence, and these can affect the foraging behavior of their natural enemies. The density of insect hosts may affect the nature and concentration of these plant-induced volatiles. We tested the impact of infestation density (low, intermediate, and high) of the pea aphid, (Homoptera: Aphididae), feeding on the broad bean , on the attractiveness of the parasitoid (Hymenoptera: Braconidae), using a Y-tube olfactometer (infested vs.

Behavioural Evidence and Chemical Identification of a Female Sex Pheromone in Anagrus atomus (Hymenoptera: Mymaridae).

Anagrus atomus (L.) is an egg parasitoid involved in the biological control of Empoasca vitis (Göthe) in vineyards. Sex pheromones play a crucial role in mate finding for several parasitoid species and could be used for monitoring under field conditions.
