Insects of extremely small size have evolved to solve many problems. Their structure and mechanical properties information can be utilized to mimic them for industrial applications. Since beetle (Coleoptera, an order of insects) wings exhibit special functionalities, they have sparked worldwide research attention. Beetle wings are composed of a forewing (also known as elytron) and a hind wing. The elytra are rigid. A beetle's functional wings, which allow flying, are the hind wings. The elytra have an ingenious structure with superhydrophobic characteristics, a structural coloration and anti-adhesion characteristics. Their inner structure helps to provide light mass and high strength. The rotation angle and wing locking system of elytra are important features which increase beetles' ability to fly; they may furnish an insight for portable micro air vehicles (MAVs) and also provide inspiration for the design of bioinspired deployable systems. Studies of the structural and mechanical properties in biological systems may improve the understanding of natural solutions and advance the design of novel artificial materials. In this paper, the structure, mechanical properties and their relationship to function of beetle wings are discussed. Examples of bioinspired structures and materials are also presented.

“…96 Este inseto apresenta uma ampla distribuição, ocorrendo principalmente na região sul do Brasil. 97 Recentemente Ambrogi e Zarbin 98 verificaram a presença de um feromônio de agregação produzido pelos machos que atraem ambos os sexos. Análises em CG demonstraram a existência de cinco compostos específicos dos machos, mas a identificação química desses compostos ainda não foi concluída.…”

Recebido em 26/9/08; aceito em 24/4/09; publicado na web em 7/10/09 AGGREGATION PHEROMONE IN CURCULIONIDAE (INSECTA: COLEOPTERA) AND THEIR TAXONOMIC IMPLICATION. The pheromones of the weevils has been the most studied and used so far for Coleoptera species. The majority of reported weevil pheromones is produced by males and usually attract both sexes. The identified pheromone compounds are classified in two categories: ten-carbon compounds with terpenoid branching and compounds of various sizes, apparently of fatty-acid origin. These pheromone structural categories are consistent within subfamilies. This review aims to give an overview of the aggregation pheromones identified for Curculionidae pests, describing the relationship of the molecules structural pattern among subfamilies, and propose an identification key based on the structure of the pheromone components.Keywords: weevils; pheromone structure; identification key. INTRODUÇÃOOs curculionídeos são besouros da superfamília Curculionoidea, com cerca de 60.000 espécies descritas.1 Os adultos da família Curculionidae são facilmente reconhecidos pela presença de uma cabeça prolongada em um rostro de comprimento muito variável, assim como antenas genículo-clavadas 2 (Figura 1). Os curculionídeos, em sua grande maioria, são fitófagos, tanto na fase larval como na adulta. 3Muitas espécies são importantes pragas de diversas culturas, bem como de grãos armazenados, e a necessidade constante de medidas de controle mais efetivas e seguras ao meio ambiente tem exigido da comunidade científica a busca por novos métodos de controle para minimizar o impacto desses insetos. Como em outros grupos de insetos, esta necessidade tem aumentado a investigação do uso de feromônios como mais uma ferramenta no manejo dessas pragas. Um trabalho extensivo tem sido feito na identificação de feromônios e seu uso dentro da família Curculionidae, 4 exemplificado pelas décadas de pesquisa conduzidas com o bicudo do algodoeiro, Anthonomus grandis.5 Seguindo a identificação de quatro componentes do feromônio de agregação de A. grandis, 6 feromônios de várias espécies de curculionídeos têm sido identificados.A maioria dos feromônios relatada em curculionídeos é produzida pelos machos e usualmente atrai ambos os sexos, por isso são conhecidos como feromônios de agregação. Entretanto, alguns feromônios também têm sido verificados em fêmeas. Estes incluem feromônios sexuais de longa-distância, que atraem principalmente machos, curta-distância ou feromônio de contato, que permitem reconhecer coespecíficos e feromônio de oviposição, que algumas fêmeas usam para marcar os hospedeiros, nos quais elas colocam seus ovos. Finalmente, existem exemplos de curculionídeos utilizando feromônios de outras espécies de besouros, como cairomônios. 4 Em virtude de seus hábitos de vida, o estudo comportamental de curculionídeos é relativamente complexo. Uma alternativa que evita muitos problemas com bioensaios e acelera o processo de identificação é a cromatografia gasosa acoplada à eletroantenografia (CG-EAG)....

“…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).…”

“…However, 20% defoliation of 3-year-old E. globulus results in significant reduction of stem growth within just one year after defoliation (Pinkard et al, 2006). In Brazil, G. scutellatus was detected for the first time in 1955 (Barbiellini, 1955;Rosado-Neto, 1993). In 2012, a new outbreak of the pest in the region of Sâo Paulo endangered plantations (Medeiros de Souza et al, 2016).…”

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.
