“…The economic impacts of some Megastigmus invasions in Europe are important, especially for M. spermotrophus on Douglas-fir and M. schimitscheki on cedar, which receive considerable attention from forest and seed orchard managers (Jarry et al 1997;Fabre et al 2004). However, the possible ecological impacts of these alien seed chalcids on both the native flora and fauna have been largely overlooked because most of the studies have taken place in intensively-managed seed orchards and plantations, not in natural stands, either for conifers or angiosperms (Mailleux et al 2008;Doğanlar et al 2009). Indeed, most studies aimed at showing an ecological effect of invasive alien insects on native species have focused on groups that are considered important for the economy or public health (e.g.…”

Cone and seed insects are considered the most important predators of tree seeds during the pre-dispersal phase of development. Among them, exotic seed chalcids in the genus Megastigmus invaded Europe as a result of the rapidly-increasing and mostly unregulated seed trade for afforestation and ornamental plantations. Unlike their economic impact in seed orchards, until recently, little attention was paid to the ecological impact of these insects. In the present study, selected case studies of alien Megastigmus spp. were considered to assess their specific impact on the potential of natural regeneration of native woody plants and on the native entomofauna competing for seed resource. We re-analyzed data from former studies that did not focus on these ecological interactions and, here, present previously unpublished results. Seeds of Douglas-fir, true cedars, true firs and wild roses were sampled all over Europe, and the relative importance of the native and invasive chalcid species was assessed as well as their specific impact on seed yield. In most cases, the recent arrival of alien chalcids resulted in a significant decrease in the regeneration potential of the host trees. In the absence of competitors, alien chalcids occupied the entire seed niche in Douglas-fir, but their impact tended to decrease after the arrival of invasive seed bugs. In firs, alien chalcids tended to displace the native chalcids, but not in wild roses and cedars, where their damage was increasing. Different biological traits that might explain invasive success of alien chalcids are discussed. However, no general invasive patterns seem to exist.

“…Eurytoma plotnikovi is generally considered as one of the most harmful pests for this crop; for example, in Tunisia, Braham et al (2010) found it in 62 out of 87 surveyed orchards (mean infestation rate 42% of the trees in each orchard, range 1–96%). In the region of Gaziantep, Turkey, 69–81% of the fruits in untreated orchards were found to be infested (Doğanlar et al, 2009). In Iran, conversely, where it used to be considered as a major pest (Jalilvand & Gholipour, 2002), it now has only a minor impact in 95% of managed crops although it is abundant on wild trees (Mehrnejad, 2020).…”

“…As alternative control measures, sanitation is of critical importance, by destroying the unharvested nuts which have fallen to the ground (Mehrnejad, 2020). Mehrnejad (2020) also indicates that no natural enemy is known, although Doğanlar et al (2009) report a 2–18% parasitism by Gugolzia karadagae (Hymenoptera: Pteromalidae) (Doğanlar & Doğanlar, 2010).…”

This is the first official report of the pistachio pest Eurytoma plotnikovi in France.Twenty adults were identified after they emerged from a sample collected in South-Eastern France. A brief description is provided, along with biological, geographical and economic data on the pest. This species should not be considered as a major concern for nut production in France so far, although this might evolve with the development of pistachio crops in this area. Eurytoma plotnikovi (Hymenoptera: Eurytomidae), ravageur du pistachier, signalé pour la première fois en France Ceci est le premier signalement officiel du ravageur du pistachier Eurytoma plotnikovi en France. Vingt adultes ont été identifiés après leur émergence depuis un échantillon collecté dans le sud-est de la France. Une courte description de cet organisme nuisible est proposée ici, ainsi que des données biologiques, géographiques et économiques. Cette espèce ne devrait pas, pour le moment, être considérée comme une préoccupation majeure pour la production de fruits à coque, mais ceci pourrait changer avec le développement des cultures de pistachier dans la région. Первое сообщение о вредителе фисташковых семян Eurytoma plotnikovi (Hymenoptera: Eurytomidae) во Франции Это первое официальное сообщение о вредителе фисташковых семян Eurytoma plotnikovi во Франции. Двадцать взрослых особей были идентифицированы после их появления из образца, собранного на юго-востоке Франции. Приводится краткое описание, а также биологические, географические и экономические данные о вредителе. Пока что этот вид не следует рассматривать как серьезную проблему для ореховодства Франции, хотя с развитием культивирования фисташковых в этой зоне ситуация может измениться.

“…Diverse works have focused on describing the arthropods pests of pistachio in different countries [ 6 , 7 , 8 , 9 , 10 ]. Among the most damaging species are, for instance, the pistachio seed wasps Eurytoma plotnikovi Nikol’skaya (Hymenoptera: Eurytomidae) and Megastigmus pistaciae Walker (Hymenoptera: Torymidae) [ 11 , 12 ], the bark beetle Chaetoptelius vestitus (Mulsant and Rey) (Coleoptera: Curculionidae) [ 13 ], the pistachio psylla Agonoscena pistaciae Burckhardt and Lauterer (Hemiptera: Psyllidae) [ 14 ] and the lepidopteran species Choristoneura rosaceana (Harris) (Lepidoptera: Tortricidae), Amyelois transitiella (Walker) (Lepidoptera: Pyralidae) and Kermania pistaciella Amsel (Lepidoptera: Tineidae) [ 7 , 15 ].…”

Laboratory Evidence of 2-Isobutyl-3-methoxypyrazine as a Male-Released Aggregative Cue in Labidostomis lusitanica (Germar) (Coleoptera: Chrysomelidae)

In spite of its incidence on pistachio trees, the chemical ecology of Labidostomis lusitanica (Germar) (Coleoptera: Chrysomelidae) has been neglected so far. In this work, we provide the first evidence of a biologically active male-specific compound that may be promoting field aggregation. Headspace collections through solid-phase microextraction from feral males and females reported the presence of 2-isobutyl-3-methoxypyrazine exclusively in males. Electroantennographic recordings revealed that males and females responded in a dose-dependent manner to increasing stimuli of 2-isobutyl-3-methoxypyrazine, with females overall displaying a higher response than males. In dual-choice tests, both males and females showed a significant preference for the compound in comparison to a pure air stimulus. In light of these results, the possible role of 2-isobutyl-3-methoxypyrazine as an aggregation cue in L. lusitanica is discussed.
