“…Em estudos realizados com extratos aquosos a 10% de pó-fumo, ramo e folhas de cinamomo, verificouse o controle de larvas de Microtheca ochroloma, ocasionando mortalidade superior a 80% a partir do terceiro dia de exposição dos insetos ao pó-de-fumo e ao ramo de cinamomo e do quarto dia ao de folha de cinamomo (DEQUECH et al, 2008 KOGAN & GOEDEN (1970), sendo classificado como fagoestimulante se o índice for maior do que um, neutro se igual a um, e fagodeterrente se foi menor do que um.…”

“…A avaliação foi realizada após dez dias, contando-se o número de larvas mortas, pupas inviá-veis e adultos com deformação. Os dados foram submetidos à análise de variância (teste F), e as médias foram comparadas entre si pelo teste de Scott-Knott (p ≤ 0,05), com auxílio do programa Sisvar (Ferreira, 2000).…”

ABSTRACT:The aim of this study was to evaluate the effect of vegetable extracts to control Ceratitis capitata. The treatments were aqueous extracts prepared with fresh and dry vegetables at a 20% w/v (weight plant/water volume) rate of chinaberry leaf, twig and fruit, rue leaf, garlic, and ginger. For the immature phase evaluation, each repetition consisted of a plaque with 20 larvae or 20 pupae, which were dipped in 1 mL of extract for 30 seconds. For the extract prepared with chinaberry dry fruits, concentrations of 0, 5, 10, 15, 10, and 25% w/v were evaluated. Analyses were made after five days by counting the number of dead larvae or pupae and the number of deformed adults. For the adult phase, only the extracts prepared with dried vegetables were assessed. Each repetition included a plastic jar containing a red plum fruit and a cotton roller soaked with 5 mL of extract. For each plastic container, three females and two males of C. capitata were transferred. After two days, the assessment of adult mortality and fruit withdrawal, which were individualized, were carried out. After seven days, the amount of larvae developed in each fruit was counted. It was found that all extracts reduced the number of viable insects, especially the chinaberry one, which also had an effect on the adult phase. In the studied conditions, no extract had effects on the fertility of C. capitata females. KEYWORDS: RESUMO: O objetivo deste trabalho foi avaliar o efeito de extratosvegetais para o controle de Ceratitis capitata. Os tratamentos foram extratos aquosos preparados com vegetais frescos e secos na proporção de 20% p/v (peso do vegetal/volume de água) da folha, do ramo e do fruto de cinamomo, da folha de arruda, do alho e do gengibre. Para a avaliação sobre a fase imatura, cada repetição foi constituída de uma placa com 20 larvas ou 20 pupas, as quais foram imersas em 1 mL de extrato durante 30 segundos. Para o extrato preparado com os frutos secos de cinamomo, foram avaliadas as concentrações de 0, 5, 10, 15, 10 e 25% p/v. As avaliações foram realizadas após cinco dias, contando-se o número de larvas mortas, de pupas inviáveis e de adultos deformados. Para a fase adulta, foram avaliados apenas os extratos preparados com vegetais secos. Cada repetição foi constituída de um pote plástico contendo um fruto de ameixa vermelha e um rolete de algodão embebido com 5 mL de extrato. Foram transferidas três fêmeas e dois machos de C. capitata para cada pote plástico. Após dois dias, realizou-se a avaliação da mortalidade de adultos e a retirada dos frutos, os quais foram individualizados, e após sete dias contou-se o número de larvas desenvolvidas. Verificou-se que todos os extratos reduziram o nú-mero de insetos viáveis, com destaque para o de cinamomo, o qual teve efeito também sobre a fase adulta. Nas condições estudadas, nenhum extrato teve resultado sobre a fecundidade das fêmeas de C. capitata.

The association of plant extracts and B. thuringiensis may be important in situations that control of different insects species is required and/or control of insects in various development stages. However, extracts may have different effects on B. thuringiensis, compromising their mode of action. Thus, the objective of this study was to evaluate the activity of aqueous plant extracts on Bacillus thuringiensis subsp. kurstaki (Btk) and their interactions on Anticarsia gemmatalis (Lepidoptera: Erebinae). Cherry plant extracts (Eugenia uniflora), pepper (Capsicum baccatum), trumpet (Brugmansia suaveolens) and grape japan (Hovenia dulcis), were used at 5% concentrations. For compatibility studies, the extracts were mixed with Thuricide® (Btk) and the parameters evaluated were Colony Formation Units (CFU mL-1) for spores and, the A. gemmatalis mortality for crystals. The cherry extracts, pepper, and japan grape completely inhibited the CFU ml-1 of Btk and the cherry extract alone negatively affected the toxicity of Btk crystals, with significantly lower mortality of A. gemmatalis (20.40%) than that observed in the control with only Btk (79.44%). In the association between cherry, pepper, and grape japan extracts with B. thuringiensis, the extracts exhibited a negative effect in the formation of CFU. The cherry extract demonstrated a negative effect on crystals action.
