Smeđa mramorasta stjenica (Halyomorpha halys Stål, 1855.) invazivna je, polifagna vrsta stjenice, koja se iz izvornog azijskog područja proširila na područje Sjeverne i Južne Amerike te Europe. Cilj ovoga rada je prikazati dosadašnja istraživanja potencijalnih prirodnih neprijatelja H. koji bi mogli primijeniti za smanjenje populacije. ima velik broj neprijatelja: kukci, gljive, nematode, mikro...

Trissolcus japonicus (Ashmead) (Hymenoptera: Scelionidae) has shown promise as a biological control agent for the invasive agricultural and nuisance pest, Halyomorpha halys (Stål) (Hemiptera: Pentatomidae). In addition to need laboratory research colonies, possibility rearing T. classical or augmentative releases necessitates investigation into efficient protocols with over timing of production...

Plants respond to insect oviposition by emission of oviposition-induced plant volatiles (OIPVs) which can recruit egg parasitoids of the attacking herbivore. To date, studies demonstrating egg parasitoid attraction to OIPVs have been carried out in tritrophic systems consisting of one species each of plant, herbivore host, and the associated egg parasitoid. Less attention has been given to plan...

I investigated mechanisms of parasitoid coexistence in a spatially structured host–multiparasitoid community (harlequin bugs [Murgantia histrionica] and two specialist parasitoids [Trissolcus murgantiae and Ooencyrtus johnsonii ]). I tested both local and metapopulation hypotheses. The local hypothesis, intraguild predation, predicts coexistence if the inferior larval competitor is superior at ...

BACKGROUND Habituation, a form of non-associative learning, has several well-defined characteristics that apply to a wide range of physiological and behavioral responses in many organisms. In classic patch time allocation models, habituation is considered to be a major mechanistic component of parasitoid behavioral strategies. However, parasitoid behavioral responses to host cues have not previ...

We investigated intraguild interactions between two egg parasitoids of Nezara viridula (L.) (Heteroptera: Pentatomidae), Ooencyrtus telenomicida (Vassiliev) (Hymenoptera: Encyrtidae) and Trissolcus basalis (Wollaston) (Hymenoptera: Platygastridae), as the former has the potential to be a facultative hyperparasitoid of the latter. We assessed the suitability of N. viridula eggs for the developme...

Abstract Unintentional introduction of natural enemies has increased in recent years due to a massive rise global trade and tourism. One such enemy is the Asian egg parasitoid Trissolcus japonicus , promising agent for classical biological control Halyomorpha halys. In Europe, adventive T. populations have been detected Switzerland, Italy Germany. Host specificity testing demonstrated that its ...
