No que tange a Luperina, Isotes eruptiva e Paranapiacaba teinturieri seguiram o mesmo padrão para as espécies do grupo estudadas até o momento, mesmo que em níveis de detalhamento diferentes (Powell 1941;Munroe & Smith 1980;Krysan & Smith 1987;Grobbelaar 1993). O gênero Diabrotica, o mais numeroso da subtribo, juntamente com os gêneros propostos a partir dele por diversos autores, incluindo Isotes Weise (anteriormente mencionado como Synbrotica Bechyné) e Paranapiacaba Bechyné, devem ser mais Figs.…”

“…Embora trabalhos com espécies de Galerucini que incluam a descrição morfológica da genitália masculina sejam relativamente escassos, mesmo se considerada a grande diversidade do grupo, ao longo dos anos algumas contribuições vêm sendo realizadas, independente do grau de detalhamento. Marques (1941) estudou membros do gênero Diabrotica Chevrolat, 1837 (Luperina); Wilcox (1965) elaborou uma sinopse das espécies de Galerucinae (= Galerucini) ocorrentes na América do Norte e considerou a presença ou ausência dos ganchos na região basal do lobo médio como caráter taxonômico fundamental para separar dois grupos de tribos; Silfverberg (1976) estudou a genitália de alguns galerucíneos africanos; Munroe & Smith (1980) revisaram as espécies mexicanas e norte-americanas de Acalymma Barber, 1947 (Luperina); Shute (1984) estudou os galerucíneos que ocorrem na Nova Guiné; Mann (1985) contribuiu para o conhecimento da genitália de Galerucinae (= Galerucini) com base em 11 espécies da Índia; LeSage (1986) revisou o gênero Ophraella Wilcox, 1965 (Galerucina); Krysan & Smith (1987) abordaram os representantes de Diabrotica do grupo virgifera, ilustrando somente o saco interno e seus escleritos; Grobbelaar (1993), ao revisar o gênero africano Megalognatha Baly, 1878 (Luperina), proporcionou importante contribuição para elucidação da genitália, tanto do macho como da fêmea e Moura (1998a,b,c;2005) estudou as espécies de Chlorolochmaea Bechyné & Bechyné, 1969, Iucetima Moura, 1998, Neolochmaea Laboissière, 1939e Caraguata Bechyné, 1954.…”

“…Among luperines, A. vittatum is relatively host specific, feeding entirely on cucurbits aside from other sources of pollen (Metcalf et al, 1998). As larvae, A. vittatum can only develop on cucurbit roots (Munroe & Smith, 1980). Most Cucurbitaceae contain cucurbitacins (bitter, oxygenated tetracyclic triterpenoids), which have been shown to deter feeding by non-adapted phytophagous insects (Tallamy et al, 1997).…”

“…Acalymma vittatum (F.) (Coleoptera: Chrysomelidae) is a notorious pest of cultivated cucurbits throughout regions east of the rocky mountains in North America (Munroe & Smith, 1980), and is well-known for remarkably rapid early season field colonization. This behaviour can result in extensive damage virtually overnight (Gaylord, 1843;Houser & Balduf, 1925;Isely, 1927;Gould, 1944), and has recently been explained by a male-produced aggregation pheromone (Smyth & Hoffmann, in review).…”

Abstract. In field studies, wind-directed traps were used to investigate the resource-based properties of the male-produced aggregation pheromone of Acalymma vittatum (F.) (Coleoptera: Chrysomelidae). Responses to early season overwintered field-collected male A. vittatum without food were compared with those feeding on pollen, and in turn these were compared with those feeding on cucurbit seedlings. These comparisons were modelled after transitions as they would occur at the initiation of A. vittatum host plant colonization.In another experiment, colony-reared male A. vittatum that had been fed only near isogenic lines of potted cucumber (Cucumis sativus) seedlings that either lacked or contained cucurbitacin were placed as bait in the traps. Using the inverse relationship, which is understood for A. vittatum, between previous exposure and the phagostimulant response to cucurbitacin, rates of foliage consumption could be manipulated. The interaction between relative rates of host plant consumption of the males used as lures and responses to the pheromone could thus be tested. The use of A. vittatum reared entirely without dietary cucurbitacin as bait also enabled evaluation of the potential role of cucurbitacin in pheromone biosynthesis. Trap responses were closely correlated with the rates of feeding of the beetles in the trap lures, but cucurbitacin was neither a precursor nor a prerequisite for the pheromone. Implications for early season field colonization and the adaptive significance of this pheromone are discussed.

Inúmeras pessoas contribuíram direta ou indiretamente para a nalização desse estudo ao longo de quatro anos de trabalho intenso. A todas elas sou muito grata.À minha família agradeço o incentivo diário e o apoio incondicional. Em especial sou grata aos meus pais, Yara e Angelo, a quem devo tudo, pelo amor e pela paciência, e por acreditarem sempre em mim.À minha orientadora, Dra. Sônia A. Casari, serei eternamente grata: por sua paciência, dedicação, otimismo, amizade e, principalmente, pela sua con ança irrestrita, que me estimulou a seguir pelo caminho apesar dos obstáculos.Ao meu supervisor no estágio de doutorado no exterior, Dr. Alexander Konstantinov, sou muito grata pela maneira como me recebeu em seu laboratório sem restrições (até mesmo na hora do chá). Agradeço a amizade e a oportunidade de discutir assuntos galerucíneos e gerais de maneira ambiciosa e divertida -e que as colaborações atuais possam se multiplicar no futuro. v Abstract Diabroticites Chapuis, 1875 (Chrysomelidae, Galerucinae, Luperini, Diabroticina) is one of the largest assemblies of chrysomelids, currently with 826 species in 17 genera, restricted to the American continent. It comprises essentially the species described in genus Diabrotica prior to 1947, characterized by the presence of bi d tarsal claws and males with simple mesothoracic tibiae. Despite having over 150 years of taxonomic history, the species in this group are mostly supported by super cial morphological treatment, frequently based in single specimens, and often relying on male characteristics. There is no general revisionary study for the section to this date, and the systematic position of Diabroticites has never been investigated as a primary objective. A cladistic analysis for the section is hereby presented, based on a detailed morphological study for several diabroticites, in order to test the group's monophyly and investigate the phylogenetic position of the genera that are comprised in it. All genera and most infrageneric groups were sampled in the ingroup with at least one terminal (in a total of 49 terminals). The outgroup comprises seven terminals representing section Cerotomites (Luperini, Diabroticina), Phyllobroticites (Luperini, Luperina), and Exosomites (Luperini, Luperina), plus one species of Coelomerites (Galerucini), regarded as the root. The sensitivity analysis included heuristic searches carried with equal and di erential weighting. The results indicate that section Diabroticites as currently de ned is not monophyletic. Its natural group status can be recovered with the addition of one or more members of the outgroup. Genera that included more than one terminal were, as a rule, not supported as clades, and the traditional diagnostic characters (along with secondary sexual characteristics) for the most part did not correspond to synapomorphies. The sole exception was Gynandrobrotica, found as a subgroup of Cerotoma. Genital characters, used for the rst time to support an evolutionary hypothesis for section Diabroticites, were found to have signi c...
