“…Although the major phagostimulants were identified as cucurbitacins B and D, the adults selectively accumulated a relatively more stable minor component, 23,24-dihydrocucurbitacin D (38), gaining bitterness effective against a bird predator. 54,57) Similarly, four Asian Cucurbitaceae-feeding specialists in the genus Aulacophora were found to sequester the same compound directly from the larval/adult host cucurbits.…”

“…Growers are unable to settle control levels. Traps to D. speciosa had been used with visual and gustatory cues (Nishida et al 1986, Roel & Zatarin 1989, Nishida & Fukami 1990, Ventura et al 1996, hence pheromone isolation, identification and synthesis may establish a suitable tool for use in lure traps to improve male beetle captures. In the same way, using 8-methyl-2-decyl-propanoate in lure traps, Meinke et al (1989) captured significantly more D. virgifera virgifera beetles than control traps throughout the season.…”

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.

“…D. speciosa sequestration and storage of 23, 24-dihydrocucurbitacin D was reported (Nishida et al, 1986;Nishida & Fukami, 1990). This insect is highly responsive to cucurbitacin from Lagenaria vulgaris L. (Roel & Zatarin, 1989;Ventura et al, 1996), and is also attracted by 1,4-dimethoxybenzene, TIC (1,2,4-trimethoxybenzene + indole + trans-cinnamaldehyde) and VIP (veratrole + indole + phenilacetaldehyde) from Cucurbita spp.…”

-The objective of this work was to evaluate arrestant and stimulant feeding effects on Diabrotica speciosa (Ger.), using cucurbitacin-content starch-based formulations prepared with varying starch sources, and adding potassium lignate. In a glass slide assay, the wash off resistance of formulations was compared. Potassium lignate did not improve wash off resistance. Lagenaria vulgaris L. powder, in which cucurbitacin B concentration was determined as 0.28%, was added to the most adhesive formulation. The resultant material was used in a two-choice assay in which leaves of common bean, Phaseolus vulgaris L., treated with concentrations of 2.5%, 5%, 10%, 15% and 20% were offered to insects together with untreated control leaves. Greater number of insects and leaves consumed were found on leaves treated with cucurbitacin-content formulation (2.5%, 5% -greatest response -, 10% and 15% concentrations) than on untreated control leaves. The concentration, in which responses were higher, was sprayed in a bean field at 1,000, 1,900 and 3,000 g ha -1 . Greater number of beetles was found in plots treated with the highest dosage, 3 and 6 days after spraying. Ten days after spraying, no significant differences were found among dosages, probably due to washoff of the bait.Index terms: Insecta, Coleoptera, bait, semiochemical, rootworm. Respostas alimentares e arrestantes de Diabrotica speciosa a formulações contendo cucurbitacinaResumo -O objetivo deste trabalho foi avaliar os efeitos alimentares estimulantes e arrestantes para Diabrotica speciosa (Ger.), a partir de formulações amiláceas com cucurbitacina, variando-se as fontes de amido e adicionando-se lignato de potássio. Em ensaio com lâmina de vidro, comparou-se a resistência à lavagem das formulações. O lignato de potássio não aumentou a resistência à lavagem. Pó de Lagenaria vulgaris L., cuja concentração de cucurbitacina B foi determinada como sendo de 0,28%, foi adicionado à formulação mais adesiva. O material resultante foi utilizado em ensaios com dupla chance de escolha, nos quais folhas de feijão, Phaseolus vulgaris L., pulverizadas com concentrações de 2,5%, 5%, 10%, 15% e 20% foram oferecidas aos insetos juntamente com folhas não tratadas. Foram observados maior número de insetos e maior quantidade de folhas consumidas nas folhas tratadas com formulações com cucurbitacina (2,5%, 5% -maior resposta -, 10% e 15%) do que nas folhas não tratadas. A formulação cuja concentração teve maior resposta foi pulverizada em lavoura de feijão, nas dosagens de 1.000, 1.900 e 3.000 g ha -1 . O maior número de adultos de D. speciosa foi encontrado nas parcelas tratadas com a maior dosagem, aos 3 e 6 dias após a pulverização. Dez dias após a pulverização, não foram encontradas diferenças entre as dosagens, provavelmente por causa da lavagem da isca pelas chuvas.Termos para indexação: Insecta, Coleoptera, isca, semioquímico, larva alfinete.
