“…Similarly, some isolates were found to be toxic to the red palm weevil Rhynchophorus ferrugineus (Olivier) (Coleoptera: Curculionidae) [ 36 ] and the boll weevil Anthonomus grandis Boheman (Coleoptera: Curculionidae) [ 1 ]. Slight toxicity was observed under laboratory conditions by topical applications of a bacterial mixture including B. laterosporus against adults of the snout-beetle Gonipterus scutellatus Gyllenhal (Coleoptera: Curculiionidae), a defoliator of Eucalyptus plantations [ 37 ].…”

Brevibacillus laterosporus, a bacterium characterized by the production of a unique canoe-shaped lamellar body attached to one side of the spore, is a natural inhabitant of water, soil and insects. Its biopesticidal potential has been reported against insects in different orders including Coleoptera, Lepidoptera, Diptera and against nematodes and mollusks. In addition to its pathogenicity against invertebrates, different B. laterosporus strains show a broad-spectrum antimicrobial activity including activity against phytopathogenic bacteria and fungi. A wide variety of molecules, including proteins and antibiotics, have been associated with the observed pathogenicity and mode of action. Before being considered as a biological control agent against plant pathogens, the antifungal and antibacterial properties of certain B. laterosporus strains have found medical interest, associated with the production of antibiotics with therapeutic effects. The recent whole genome sequencing of this species revealed its potential to produce polyketides, nonribosomal peptides, and toxins. Another field of growing interest is the use of this bacterium for bioremediation of contaminated sites by exploiting its biodegradation properties. The aim of the present review is to gather and discuss all recent findings on this emerging entomopathogen, giving a wider picture of its complex and broad-spectrum biocontrol activity.

“…This egg parasitoid has been reported as effective in many situations (Hanks et al, ; Lanfranco & Dungey, ; Tooke, ). However, in some high altitude areas, experiencing colder winters, the wasp fails to reduce weevil populations below the economic threshold of damage (Echeverri‐Molina & Santolamazza‐Carbone, ; Gumovsky, De, Rothmann, Jaques, & Mayorga, ; Loch, ; Reis et al, ; Tribe, ). Consequently, G. platensis remains a threat to eucalyptus economic viability in many world regions (Echeverri‐Molina & Santolamazza‐Carbone, ; Gumovsky et al, ; Loch, ; Reis et al, ; Tribe, ).…”

The eucalyptus weevil, Gonipterus platensis (Coleoptera, Curculionidae), is a major pest of eucalyptus plantations worldwide. To date, no pheromones have been identified for this species, despite their valuable potential as tools in monitoring or control strategies. Here we report the detection and identification of pheromones candidates of G. platensis. The weevil's volatile compounds were collected by solid phase micro extraction (SPME) and monolithic material sorption extraction (MMSE). Using Gas Chromatography coupled to Mass Spectrometry (GC/MS) analysis, eleven insect specific compounds were detected and identified: verbenene, cis‐verbenol, trans‐verbenol, verbenone, 2‐oxo‐1,8‐cineole, 9‐hydroxy‐1,8‐cineole, 2‐α‐hydroxy‐1,8‐cineole, 3‐oxo‐1,8‐cineole, 2‐β‐hydroxy‐1,8‐cineole, 3‐α‐hydroxy‐1,8‐cineole and 7‐hydroxy‐1,8‐cineole. Three of these compounds, verbenene, cis‐verbenol and trans‐verbenol, were shown to be male‐specific. Antennal sensitivity towards ten compounds emitted by G. platensis was detected using Gas Chromatography–Mass Spectrometry/Electroantennographic Detection (GC‐MS/EAD). Extracts from virgin males proved to be attractive to virgin females in olfactometer bioassays. Further behavioural bioassays showed that both virgin females and virgin males were attracted to the male‐specific compound cis‐verbenol and that virgin females were attracted to trans‐verbenol. Verbenone was attractive to mated females. Regarding 2‐α‐hydroxy‐1.8‐cineole and 2‐oxo‐1,8‐cineole, which are produced by both sexes, the alcohol was attractive to virgin males and both the alcohol and the ketone were repellant to mated females. This is, to our knowledge, the first identification of pheromones candidates in Gonipterus spp. and also the first evidence of cineole metabolites acting as semiochemicals.

“…Vuill. (Ascomycota: Hypocreales: Cordycipitacea) and Metarhizium anisopliae (Metsch) Sorokin (Hypocreales: Clavicipitaceae) can rapidly spread in the field (Meyling et al, 2009;Costa et al, 2015) and regulate Eucalyptus pest populations (Sun et al, 2008;Echeverri-Molina and Santolamazza-Carbone, 2010). Thus, this study evaluated the susceptibility of T. peregrinus to two commercial products based on conidia of B. bassiana and M. anisopliae.…”

Thaumastocoris peregrinus Carpintero and Dellape (Hemiptera: Thaumastocoridae) is a sap-sucking insect that has become a major pest of eucalypts. The entomopathogenic fungi Beauveria bassiana (Bals.-Criv.) Vuill. and Metarhizium anisopliae (Metsch.) Sorokin have the potential to control insect pests. This study evaluated the susceptibility of T. peregrinus to two commercial products based on conidia of B. bassiana and M. anisopliae. The fungi were sprayed onto adults of T. peregrinus at a concentration of 1 × 10 8 conidia mL −1 to evaluate their pathogenicity and conidial production on the insect cadavers. Beauveria bassiana caused 100 % mortality, while M. anisopliae caused more than 80 % mortality of T. peregrinus adults 11 days after fungi application. The fungi colonized the head and thorax regions and caused high mortality rates through conidial production. Pathogenicity of entomopathogenic fungi B. bassiana and M. anisopliae to T. peregrinus show potential to use these fungi in integrated pest management.
