“…The sources of species-level identifications were varied. Twelve species were identified because BOLD contained sequences representing named specimens sequenced in other projects, eleven were identified based on sequences that had been submitted to GenBank for currently unpublished research, ten were based on sequences submitted to GenBank as a part of published molecular phylogenetic studies [43][44][45][46][47][48], eight were from taxonomic revisions of various genera [13,49,50] that included barcode data, four were from studies of particular pest species and their parasitoid complexes [51][52][53][54], three were from a barcoding study of Canadian insects [33,55], two were from a barcoding inventory of Finland [56], and one was from the barcoding of German specimens held in a German museum [57]. The remainder are widespread, often commercially important parasitoids of crop or forestry pests; for example, the aphid parasitoids, Binodoxys acalephae and Lipolexis oregmae (both Braconidae, Aphidiinae) are important and widespread parasitoids of Aphis gossypii and numerous other aphids, and the almost-cosmopolitan polyembryonic encyrtid, Copidosoma floridanum, is a major and important parasitoid of many pest species of plusiine noctuid moths and, no doubt, of many more non-pest species [58,59].…”

We report the results of DNA barcoding week-long Malaise trap catches from 11 sites in three Thai conservation areas, concentrating on the parasitoid Hymenoptera, particularly the superfamily Ichneumonoidea. From a total of 15,338 parasitoid wasp sequences, 13,473 were barcode compliant and could be assigned to a family based on morphology and sequence data. These collectively represented 4917 unique BINs (putative species) in 46 families, with the Scelionidae, Ichneumonidae, Eulophidae, Braconidae and Platygastridae being, by far, the most abundant. Spatial proximity had a strong positive effect on the numbers of BINs shared between traps.

“…Pyrethroid insecticides are applied to the crop in summer when the hazelnuts are most vulnerable to P. prasina attacks, but with limited success and with negative environmental impacts (Ceuppens et al., 2015; Liu et al., 2012). Although biological control strategies using entomopathogenic fungus (Ozdemir et al., 2021), bacteria (Ozsahin et al., 2014) or parasitoids are under study (Ozdemir et al., 2023), to date, no comprehensive IPM strategy for the control of P. prasina is available. There is thus a need to advance our knowledge of the overall temporal and landscape ecology of the GSB.…”

Palomena prasina, the green shield bug (GSB), is widely distributed in the Eurosiberian region. In the Southwest of France, it is considered as a serious pest of hazelnuts, its feeding punctures lead to blank hazelnuts and kernel necrosis, causing heavy losses in commercial orchards. To date, no Integrated Pest Management strategy is available to control P. prasina. Control strategies often focus on the pests' spring–summer ecology, when they are in the field or in the vicinity of crops. However, the abundance of pest populations in crops is also related to their autumn‐winter ecology. The present work focussed on the autumn‐winter ecology of P. prasina to identify new opportunities for this pest suppression. We investigate (i) where P. prasina overwinters, (ii) if it aggregates in its overwintering sites and (iii) if it mates while overwintering. Samples were collected over a 2‐year period in different ecosystems (forests, hedges, orchards), in human‐made structures and habitats (litter, bushes/trees, dead trees). The reproductive status of GBS individuals was monitored in winter, and in spring when they emerged from overwintering sites. Our results show that 97% P. prasina adults overwinter in the leaf litter of orchards and natural ecosystems and that 70% overwinter individually. The abundance of GSB in those sites is negatively correlated with litter temperature and positively correlated with humidity levels. Furthermore, adults only mate after leaving their overwintering site. Finally, unexpectedly, there was an important number of overwintering adults hosting endoparasitoids (32%). The fact that GSB overwinters alone in the leaf litter means controlling its populations by destroying the overwintering sites is not a solution. All the same, our results point out some promising lines of research for developing methods to control P. prasina. First, the emergence traps, in particular the cone traps, proved efficient for collecting emerging adults and could be considered for monitoring. Moreover, our observations suggest the existence of long‐range mating signals that could be exploited for trapping. Last but not least, the important number of overwintering parasitised adults is a potential biocontrol avenue.

In recent years, the collection of eggs of stink bugs (Pentatomidae) has intensified because of the attention given to egg parasitoids in classical biological control strategies against Halyomorpha halys (Stål) in Europe. Several specimens belonging to the genus Telenomus Haliday emerged from field-collected pentatomid eggs. Taxonomic knowledge to date has not been sufficient to enable the research community to identify these specimens to species level. Three species of scelionid wasps (Scelionidae) associated with Pentatomidae, Telenomus gifuensis Ashmead, Telenomus truncatus (Nees von Esenbeck) and Telenomus turesis Walker, have been characterized on a morphological basis. A COI barcode analysis confirmed the genetic distance between the latter two species. An identification key to the three Telenomus species occurring in the Palearctic region associated with stink bugs is provided. Telenomus heydeni Mayr is here considered conspecific with Telenomus truncatus (Nees von Esenbeck).
