Further contributions to the tritrophic plant-aphid-parasitoid associations in Malta with special reference to Aphis nerii (Hemiptera, Aphidoidea) as a prevalent refugium of Aphidiinae (Hymenoptera, Braconidae) [PDF]

open access: yes, 2013
Four species of aphid parasitoids, namely Aphidius colemani, Binodoxys angelicae, Lysiphlebus fabarum and Lysiphlebus testaceipes were reared from Aphis nerii on Nerium oleander and/or Stephanotis floribunda in Malta.

Parasitoid load affects plant fitness in a tritrophic system

open access: yes, 2008
Plants attacked by herbivorous insects emit volatile compounds that attract predators or parasitoids of the herbivores. Plant fitness increases when these herbivorous insects are parasitized by solitary parasitoids, but whether gregarious koinobiont ...

Metabarcoding of Pollen Carried by Syrphids Reveals Novel Plant–Pollinator Interactions in a Protected Natural Area and Agricultural Sites

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Using DNA metabarcoding, this study investigates pollen transported by syrphids (Syrphidae) in the Dolomiti Bellunesi National Park and agricultural sites in Northern Italy. The analysis reveals a high diversity of visited plant taxa, including previously undocumented plant–pollinator interactions.

The Parasitoid Wasp Glyptapanteles porthetriae Induces a Photoperiod‐Dependent Diapause‐Like State in Its Potential Overwintering Host Lasiocampa quercus

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
We evaluated Lasiocampa quercus as an overwintering host for the koinobiont larval endoparasitoid Glyptapanteles porthetriae by exposing parasitized larvae to different environmental conditions and comparing parasitoid development with that in the primary host Lymantria dispar.

Performance of Leptopilina japonica Novković and Kimura (Hymenoptera: Figitidae) Under Fluctuating Temperature and Humidity

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Temperature is an important factor to determine the activity of insects. We tested the performance of the non‐native larval parasitoid Leptopilina japonica (Hymenoptera: Figitidae) under realistic climatic conditions to improve understanding about its ongoing spread and seasonal abundance.

Natural Parasitism of Nezara viridula (Linnaeus) (Hemiptera: Pentatomidae) by Trichopoda pictipennis Bigot (Diptera: Tachinidae) in an Organic Strawberry Field in Germany

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Natural parasitism of the invasive southern green stinkbug was recorded in an organic strawberry cropping system in southwestern Germany. The tachinid fly Trichopoda pictipennis shows successful establishment and field activity, indicating ongoing range expansion.

Ecosystem Services Against Illegal Immigration: The Natural Control of the Migratory Butterfly Painted Lady (Vanessa cardui) by Cotesia vestalis (Hymenoptera, Braconidae) on Organic Soybean in Ukraine

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
In central Ukraine, the migratory butterfly Vanessa cardui emerged as a key pest of organic soybean during its outbreaks in 2019 and 2022. Despite early defoliation, crops recovered strongly due to high parasitism by Cotesia vestalis, reaching 100% in some fields.
