Updated list of the insect parasitoids (Insecta, Hymenoptera) associated with Lobesia botrana (Denis & Schiffermüller, 1775) (Lepidoptera, Tortricidae) in Italy. 2. Hymenoptera, Ichneumonidae, Anomaloninae and Campopleginae

Abstract

In this second review of the parasitoids recorded on Lobesia botrana (EGVM) in Italy, an updated list and summary of the information available on 14 taxa of Ichneumonidae belonging to the subfamilies Anomaloninae and Campopleginae are provided. For each taxon, geographic distributions, host ranges, ecological role in viticulture and/or in other crops, and taxonomy are provided and discussed. For the most interesting species, tables summarizing the parasitization rates recorded in the field on EGVM or other lepidopteran pests are given. Identification mistakes and wrong synonymies that have generated great confusion and often made geographic distributions and host ranges unreliable are highlighted. A list of four Anomaloninae and 27 Campopleginae recorded on EGVM in Europe is also provided. Among the species examined, Campoplex capitator Aubert is the only potential candidate for biological control of EGVM.

Taxonomic revision of the Campoplex difformis group (Ichneumonidae, Campopleginae), with particular reference to species of economic importance

“…The campoplegine genus Campoplex Gravenhorst, 1829 includes more than 200 species worldwide (Yu et al 2016), with most of the described species in the Western Palaearctic (about 100 valid species) (Yu et al 2016;Horstmann 2012;Zwakhals & van Achterberg 2017). Species of Campoplex are koinobiont endoparasitoids of Lepidoptera (Shaw & Aeshlimann 1994;Athanassov et al 1998;Jenner & Kuhlmann 2006) and many species are of economic importance, having been employed in biological control programs (Bartlett et al 1978;Jenner et al 2005;Scaramozzino et al 2018).…”

“…During investigations on ichneumonid parasitoids of the European grapevine moth (EGVM), Lobesia botrana (Denis & Schiffermüller, 1775), in Italy (Scaramozzino et al 2018), we came across taxonomic confusion surrounding two morphologically similar species, Campoplex difformis (Gmelin, 1790) and C. capitator Aubert, 1960, both related to the biological control of this important pest of vineyards. Recent studies showed that C. capitator may represent one of the best candidates for EGVM control (Ioriatti et al 2011;Lucchi et al 2017).…”

Wing‐fanning frequency as a releaser boosting male mating success—High‐speed video analysis of courtship behavior in Campoplex capitator, a parasitoid of Lobesia botrana

“…Campoplex capitator Aubert (Hymenoptera: Ichneumonidae) is a solitary koinobiont larval endoparasitoid of tortricids (Ioriatti et al, 2011). This species, first reported Notably, the C. capitator development is steadily synchronized with L. botrana (Scaramozzino et al, 2018), with parasitoid females ovipositing in 2nd-4th instar L. botrana larvae (Thiéry, 2008;Villemant et al, 2011). Earlier research outlined good parasitization rates of C. capitator on L. botrana (Silvestri, 1912;Pinna et al, 1989;Bagnoli & Lucchi, 2006).…”

“…Campoplex capitator Aubert (Hymenoptera: Ichneumonidae) is a solitary koinobiont larval endoparasitoid of tortricids (Ioriatti et al ., 2011). This species, first reported on Lobesia botrana (Denis & Schiffermüller) by Coscollá (1980), is widely distributed in the Mediterranean areas, including Iberian Peninsula, France, Corsica, Italy, Switzerland, and Turkey (Zwakhals & van Achterberg, 2017; Scaramozzino et al ., 2018). Interestingly, it is characterized by a rather narrow host range, including three grapevine pests, the European grapevine moth (EGVM), L. botrana (Yu et al ., 2012; Moreau et al ., 2019), Eupoecilia ambiguella Hübner, and Sparganothis pilleriana (Denis & Schiffermüller) (Villemant et al ., 2011; Thiéry et al ., 2018).…”

“…Notably, the C. capitator development is steadily synchronized with L. botrana (Scaramozzino et al ., 2018), with parasitoid females ovipositing in 2nd–4th instar L. botrana larvae (Thiéry, 2008; Villemant et al ., 2011). Earlier research outlined good parasitization rates of C. capitator on L. botrana (Silvestri, 1912; Pinna et al ., 1989; Bagnoli & Lucchi, 2006).…”
