“…defoliator beetle, Gonipterus platensis (Marelli, 1926) (Coleoptera: Curculionidae) (Souza et al, 2016). This parasitoid is originally from Australia (Mapondera et al, 2012), and it has been successfully introduced in South Africa, Spain and California (United States of America) (Cordero-Rivera et al, 1999;Hanks et al, 2000) but with low efficiency in some hyperparasitoids (Van Nouhuys et al, 2016) and alter the structure and composition of parasitoid communities (Rothacher et al, 2016;Monticelli et al, 2019). It is important to know the host microbiota to evaluate its interference in parasitoid efficiency in biological control programs (Almeida et al, 2010).…”

Endosymbiont bacteria can affect biological parameters and reduce the effectiveness of natural enemies in controlling the target insect. The objective of this work was to identify endosymbiont bacteria in Anaphes nitens (Girault, 1928) (Hymenoptera: Mymaridae), the main natural enemy used to manage Gonipterus platensis (Marelli, 1926) (Coleoptera: Curculionidae). Genomic DNA from six A. nitens populations was extracted and polymerase chain reactions (PCR) were performed with the primers to detect endosymbiont bacteria in this insect. The PCR products were amplified, sequenced, and compared with sequences deposited in the GenBank for the bacteria identification. All A. nitens populations had the bacterium Yersinia massiliensis (Enterobacteriales: Enterobacteriaceae). This bacterium was originally described as free-living, and it is associated with and composes part of the A. nitens microbiota. This is the first report of Y. massiliensis in an insect host.

“…The egg parasitoid Anaphes nitens (Girault, 1928) (Hymenoptera: Mymaridae) has been used for the biological control of G. platensis (Hanks et al, 2000), but this pest has been causing high damage levels (Echeverri-Molina and Santolamazza-Carbone, 2010). The life cycle of entomopathogenic nematodes in the soil make them promising biological control agents of insects with part of its life cycle in the soil as eucalyptus weevils (Barbosa-Negrisoli et al, 2010;Grewal, 2000) including G. platensis.…”

“…Biological control was one of the first strategies used to control G. platensis. The Australian egg parasitoid Anaphes nitens Girault (Hymenoptera: Mymaridae) has been introduced into all continents where the snout beetle is present, with good results (Arzone 1985;Cordero-Rivera et al 1999;Hanks et al 2000;Lanfranco and Dungey 2001;Tribe 2005). However, the parasitoid has not been efficient in reducing the damage caused by G. platensis below economically sustainable levels in several regions, in particular in cooler regions of countries such as Portugal, Spain, or Chile (Cordero-Rivera et al 1999;Lanfranco et al 2011;Reis et al 2012;Valente et al 2018).…”

“…In countries where G. platensis is present, E. globulus is consistently found to be a preferred host, even though several other species have also been identified as susceptible, such as Eucalyptus camaldulensis Dehnh., E. grandis W.Hill, E. longifolia Link, E. obliqua L'Hér., E. propinqua Deane & Maiden, E. robusta Sm., and E. viminalis Labill. (Cordero-Rivera and Santolamazza-Carbone 2000;Hanks et al 2000;Huerta-Fuentes et al 2008;Lanfranco and Dungey 2001).…”

& Key message Gonipterus platensis is an important insect pest of eucalypt plantations. Despite biological control by the egg parasitoid Anaphes nitens, economic losses remain high in several areas outside its native range where susceptible eucalypt species are grown in commercial plantations. The susceptibility to G. platensis of 17 Eucalyptus species was evaluated and possible alternatives for reforestation in high pest incidence areas were identified. & Context Gonipterus platensis is an important pest of Eucalyptus worldwide. Despite biological control, it causes significant losses to Eucalyptus plantations in several areas, requiring alternative management options. & Aims We analysed host preference of G. platensis towards 17 Eucalyptus species to identify less susceptible plant materials that could be used in areas of high pest incidence. & Methods Feeding damage was assessed in field trials in three consecutive years. No-choice and choice tests were conducted with Eucalyptus species of contrasting susceptibility. & Results Within subgenus Symphyomyrtus, all species from section Maidenaria were used by G. platensis for feeding. Within this section, E. globulus was always the preferred species, while E. nitens was the least preferred. Differences in susceptibility were less pronounced at high attack intensity by G. platensis. Eucalyptus saligna (section Latoangulatae) was the least preferred species among Symphyomyrtus. All species from subgenus Eucalyptus had low susceptibility to G. platensis, particularly E. regnans, which was never attacked under field conditions. The results were confirmed by choice and no-choice laboratory and semi-field tests. & Conclusion Significant differences in susceptibility to G. platensis were found between the 17 Eucalyptus species tested, which could be explored for reforestation with less susceptible plant materials.
