“…Richardson and Meakins (1986) demonstrated a wide variation in susceptibility between and within eucalypt species. Clarke et al (1998) pointed out that E. globulus and E. viminalis are generally considered as the most susceptible species in newly invaded areas, however in part of its native range (Tasmania), the most susceptible species are E. pulchella, E. tenuiramis and E. amigdalina.…”

“…In addition, molecular characterisation is needed to confirm the taxonomic identity and phylogeny (Echeverri et al, 2007Garnas et al, 2011Mapondera et al, 2012). Although different Gonipterus species may share the same life cycle and biology, it has been observed that the Eucalyptus species they attack may vary (Tooke, 1935;Richardson and Meakins, 1986;Clarke et al, 1998;Cordero Rivera and Santolamazza Carbone, 2000) with, probably, a correlation between the distribution range of the Eucalyptus hosts and the native range of the weevils (Newete et al, 2011).…”

“…Also known as the Eucalyptus snout-beetles, the species belonging to the genus Gonipterus have little economic significance in the Australian continent, whereas outside of their native range, they are some of the most harmful defoliators of several Eucalyptus species (Marelli, 1927;Frappa, 1950;Tooke, 1955;Cadahia, 1986a,b;Richardson and Meakins, 1986;Rosado-Neto, 1993;Cordero Rivera et al, 1999;Lanfranco and Dungey, 2001;Reis et al, 2012). Despite their torpid and slow movements, the members of the G. scutellatus complex are strong flyers and may live up to 12 months in the field (Mally, 1924;Tooke, 1955).…”

“…Nearly 80% of the timber (including Eucalyptus) imported from South America into Europe originates from Brazil where the pest is present, and the rest is imported from Argentina (G. scutellatus present), Paraguay, Ecuador, Bolivia, and Uruguay (Forest Trends, 2013). Uruguay, which was colonised by the pest in 1943 (Kober, 1955;Richardson and Meakins, 1986), is an important exporter of sawlogs of E. globulus to the Iberian Peninsula (ENCE, 2002).…”

The Panel on Plant health performed a pest categorisation of the Australian Eucalyptus snout-beetle Gonipterus scutellatus (Coleoptera: Curculionidae), for the EU. G. scutellatus should be referred as the G. scutellatus species complex because it includes several cryptic species. A complete nomenclature of the species present in the EU is still pending. It is a quarantine pest listed in Annex IIB of Council Directive 2000/29/EC. Protected zones are in place in Greece and Portugal (Azores). In the EU, it has been found in Italy, France, Spain and Portugal. It only consumes Eucalyptus species leaves. The main pathways of spread are the trade of Eucalyptus timber, hitchhiking in various commodities, trade of apple fruit as well as of plants for planting or plant parts. Spread by flight is also possible. The climate of the EU protected zones is similar to that of the Member States (MS) where the G. scutellatus complex is established, and the pest's main host plants are present. The damaged trees suffer die-back and the development of epicormics shoots. Severe attacks may provoke massive amounts of tree death. Biological control by using the egg parasitoid wasp Anaphes nitens is the most effective control measure. Some species within the G. scutellatus complex are not yet present in the EU (including G. scutellatus sensu stricto) and might therefore be considered as potential union quarantine pests for the EU territory. At least two species within the G. scutellatus complex (most likely G. platensis and Gonipterus species no. 2) meet the criteria assessed by EFSA for consideration as potential protected zone quarantine pests for the territory of the protected zones: Greece and Portugal (Azores). The criteria for considering the G. scutellatus complex as a potential regulated nonquarantine pest for the EU are not met since plants for planting are not the main pathway.

“…Gyllenhal is an Australian insect specialised for eucalyptus (Withers 2001), where it is considered one of its major pests because of the important damage caused to plantations in many countries in Africa and Europe (e.g., Arzone &Meotto 1978;Rabasse & Perrin 1979;Richardson & Meakins 1986;Mansilla 1992;Cordero et al 1999), California, United States (Cowles & Downer 1995;Hanks et al 2000), and New Zealand (Cadahia 1980). In South America, the species was first reported for Argentina in 1926 by Marelli (Rosado 1993).…”

Gonipterus scutellatus (Coleoptera: Curculionidae) is a pest of eucalyptus in Chile. Susceptibility of Eucalyptus camaldulensis, E. globulus ssp. globulus, and E. robusta to larval feeding were studied by determining foliar area loss. The effect of feeding on larval protein profiles was analysed by electrophoresis. E. camaldulensis was more susceptible (11.21% foliar area consumed) than E. globulus (6.47%) and E. robusta (3.62%). Nineteen proteins were common in larvae fed the three kinds of food, whereas 11 exhibited variations (marker proteins). As all larvae came from E. globulus providing the same nutrition, relatively few (20) proteins were detected in them. More proteins (30) were found in larvae feeding on E. robusta. The greatest number of marker proteins occurred in E. robusta (11), followed by E. camaldulensis (9), and E. globulus (1). Thus, larvae fed on three eucalyptus species had three different protein profiles.

Toxicity by contact and by ingestion of lufenuron, flufenoxuron, lambda (k)-cyhalothrin, cypermethrin, thiamethoxam and five entomopathogenic insecticides (three formulations of Beauveria bassiana, a compound containing spores of Metarhizium anisopliae var. acridum, and a mixture of Brevibacillus laterosporus, Bacillus licheniformis and Bacillus chitinosporus) were evaluated on adults of the Eucalyptus snout-beetle Gonipterus scutellatus Gyllenhal (Coleoptera: Curculionidae) under laboratory conditions. By contact, entomopathogenic fungus B. bassiana EC and the pyrethroid k-cyhalothrin exhibited the highest efficiency, achieving 100 and 97.5% mortality, respectively. By ingestion, the highest mortality was obtained by B. bassiana EC (100%) and thiamethoxam (95%). Flufenoxuron and lufenuron, bacteria mixture and M. anisopliae showed a weak toxicity. Furthermore, we found a sex-biased mortality, being males more affected. Due to the good performance and low risk to humans and environment, B. bassiana EC (strain PPRI 5339) appears to be the most promising product to promote an IPM programme in South Africa.
