“…D. virgifera virgifera was also more attracted to light yellow than to red, blue, dark blue and ultraviolet colors in the laboratory (Ball, 1982). On cucurbits, yellow traps attracted more Acallyma vittatum (F.), and D. virgifera virgifera beetles than did white traps, but capture numbers of Acallyma trivittatum (Mannerheim) and D. undecimpunctata howardi were similar on both trap colors (Hoffmann et al, 1996). Future investigations may determine responses to hue, brightness and saturation of yellow and other colors with similar wavelengths.…”

“…Diabroticites are also attracted to volatile compounds from Cucurbita maxima Duchesne blossoms (Metcalf & Metcalf, 1992) which rising doses may increase the attraction in a dose-dependent manner. This would be advantageous for mass trapping (Hoffmann et al, 1996) and applies to D. speciosa, which responds to 1,4-dimethoxybenzene as a volatile attractant (Ventura et al, 2000). Yellow baited traps have been used to capture D. speciosa (Ventura et al, 1996;2000;2001).…”

Refinements in trap characteristics may improve ability to monitor and mass-trap beetles. Field assays were conducted in common bean fields to assess responses of Diabrotica speciosa (Germar) to some trap characteristics. Golden yellow plastic cups (750 mL) traps caught more D. speciosa females and males than did clear traps. Carrot slices in Petri dishes baited with Lagenaria vulagaris L. powder (cucurbitacin source -0.28%) caught more beetles than did dishes with carrot alone. Dispensers for the floral volatile attractant 1,4-dimethoxybenze were also compared. Rubber septa dispenser attracted more beetles than did control (dental wicks saturated with acetone). Captures on dental wick, starch matrix and feminine pad dispensers were intermediate and did not differ from those on rubber septa and unbaited controls. Perforated bottle traps (2000 mL), when baited with the floral attractant, caught more beetles than did window bottle traps (both traps contained L. vulgaris powder) in most assessments done from two to ten days after trap placement in the field. Traps with the insecticide carbaryl captured more beetles than did traps without it, 2-4 and 8-10 days after trap placement in the field, but not in the remaining periods (0-2, 4-6 and 6-8 days). Traps baited with 1,4-dimethoxybenzene captured more beetles than did the unbaited ones in all assessments (each other day from two to ten days after trap placement in the field). Finally, similar amounts of beetles were captured using plastic bottle traps (2000 mL): perforated, window (both with cucurbitacin) and sticky (without cucurbitacin) traps, when were baited with the floral attractant. Key words: attractant, feeding stimulant, semiochemical, integrated pest management ATRIBUTOS DA ARMADILHA INFLUENCIAM CAPTURA DE Diabrotica speciosa (COLEOPTERA: CHRYSOMELIDAE) EM FEIJOEIRORESUMO: Refinamentos em caraterísticas de armadilhas podem incrementar sua habilidade para monitorar e capturar em massa os insetos. Experimentos foram conduzidos em lavoura de feijoeiro para verificar as respostas de Diabrotica speciosa (Germar) a algumas características de armadilhas. Armadilhas de copos plástico (750 mL) amarelo ouro capturaram mais fêmeas e machos de D. speciosa do que transparentes. Placas de Petri com pedaços de cenoura, com pó seco de purungo, Lagenaria vulgaris L. (fonte de cucurbitacina -0,28%) capturaram mais insetos do que placas com somente cenoura. Liberadores para o atraente floral 1,4-dimetoxibenzeno foram também comparados. Liberador de septo de borracha atraiu mais insetos do que o controle (flocos dentais saturados com acetona). Capturas nos tratamentos com liberadores de floco dental, matriz borato e absorvente higiênico foram intermediárias mas não diferiram da testemunha e septo. Modelo de armadilha de garrafa (2000 mL) furada capturou mais insetos do que armadilha vazada ("janelas") (ambas contendo pó seco de purungo) na maioria das avaliações, dos dois até os dez dias após a instalação das armadilhas no campo. Armadilhas com inseticida carbary...

“…Significant interactions between trap colors and attractants in the capture of D speciosa (Table 2) corroborate results obtained with D. virgifera virgifera (Hesler and Suter, 1993) in which interactions were also found between trap grant and attractant. However, in a series of experiments with four species of diabroticites, Hoffman et al (1996) found significant interactions for D. undecimpunctata undecimpunctata Mannerheim. Higher number of insects caught by 2 L bottle traps (Table 2) corroborated reports of rising captures of Diabrotica spp.…”

“…trap height captures, in general, have been recorded as variable, according to crop development. Hoffmann et al (1996) found that in capturing striped cucumber beetle in the small and mediumheight squash, traps placed closest to the ground were the most effective. On the other hand, in taller cucurbits they would be positioned at mid-or upper canopy level.…”

“…Studies are restricted on the North American species of Diabrotica, to which, besides pheromones, natural compounds from host plants (kairomones) have been focused (e.g., Metcalf & Lampman 1989, Deem-Dickson & Metcalf 1995. Pheromones, volatile and non-volatile kairomones have been proposed to monitor and control Diabrotica spp (e.g., Deem-Dickson & Metcalf 1995, Herbert et al 1996, Hoffmann et al 1996, Ventura et al 1996, 2000. This study was conducted to suggest the pheromone production by adults of D. speciosa.…”

Neotropical Entomology 30(3): 361-364 (2001) Machos são Atraídos por Armadilhas com Fêmeas: Uma Nova Perspectiva para Manejo de Diabrotica speciosa (Germar) (Coleoptera: Chrysomelidae) Usando Feromônio Sexual RESUMO -As respostas de Diabrotica speciosa (Germar) para armadilhas com adultos foram estudadas como sugestão da produção de feromônio. Inicialmente, um ensaio para estabelecer a altura adequada para colocação de armadilhas para capturar D. speciosa foi conduzido em campo de feijão. Armadilhas colocadas a 0,25 m de altura capturaram cerca de 3,5 vezes mais adultos do que a 0,5; 0,75 e 1,0 m. As respostas para fêmeas e machos virgens de duas idades (mais novos = 24 a 72h e mais velhos = 72 a 120h após emergência de adultos), fêmeas e machos copulados foram avaliadas em campo de feijão consorciado com café, Coffea arabica L. Armadilhas com fêmeas virgens capturaram cerca de 22 (mais jovens) e 13 vezes (mais velhas) mais adultos machos do que as testemunhas (armadilhas sem insetos). Capturas foram cerca de 70% mais efetivas usando fêmeas mais jovens. Nenhum dos outros tratamentos aumentou as capturas nas armadilhas. Os resultados indicam que há um feromônio sexual produzido por fêmeas em D. speciosa. PALAVRAS-CHAVE:Insecta, semioquímico, altura de colocação de armadilhas, Luperini, Fucata.ABSTRACT -The field responses of Diabrotica speciosa (Germar) to traps baited with adults were studied as an suggestion of the pheromone production. Firstly, an assay to settle a suitable height placement to capture D. speciosa was carried out in common beans, Phaseolus vulgaris L., field. Traps placed at 0.25-m height captured ca. 3.5 times more beetles than 0.5, 0.75 and 1.0-m traps. The responses to virgin females and males of two ages (younger = 24 to 72h and older = 72 to 120h after adult emergence), mated females and males were assessed in common bean interplanted among coffee, Coffea arabica L., field. Virgin females baited traps captured ca. 22 times (younger) and 13 times (older females) more male beetles than control traps. Captures were ca. 70% more effective using younger females. None of the other treatments improved trap attraction. These results strongly indicated that there is a female-produced sexual pheromone in D. speciosa.
