“…The aqueous extracts of the leaves and the roots (0.1 v/v) showed insecticidal activity against the mots with IC 50 value of 50.0 and 52.5, respectively. This activity was also observed by Tavares and Vendramim (2005) when used the same plant extracts and same strain with minimal insecticidal activity of 50%. At 0.2 v/v of concentration, the aqueous extracts of the leaves and the roots showed the IC 50 values of 80 and 90 on the second day of the treatment ( Table 2).…”

The present work deals with the influence of the powders, aqueous and methanolic extracts of Chenopodium album plant on survival of the Brassica oleacera moth, Plutella xylostella (Diamondback moth), as well as, the phytochemical studies of the chemical constituents present in the leaves extract of C. album. The powders tested were obtained from the roots and the leaves of the plant. The insecticidal activity was evaluated using the leaf disc immersion method. The powders of the leaves (IC 50 value 100% at 0.1 g and 0.3 g, respectively), powder of the roots (IC 50 values 77.5% at 0.1 g and 95.0% at 0.3 g), aqueous extract of the leaves (IC 50 values 50.0% at 0.1 v/v and 80.0% at 0.2 v/v), aqueous extract of the roots (IC 50 values 52.0% at 0.1 v/v and 90.0% at 0.2 v/v) and the methanolic extract of the roots (IC 50 value 72% at 0.

“…However, the plant species evaluated in this study were selected on the basis of their biocidal potential, their taxonomic status (genus/family), or their constituents. According to Tavares & Vendramim (2005), the availability of active compounds in plants may vary depending on the solvent used in the preparation of the extracts. This finding indicates that the possibility of detecting biocidal activities in these plant species or finding extracts with higher toxicity should not be ignored.…”

RESUMENEsta investigación tiene el objetivo de hacer una selección de especies vegetales que son propias de la región Amazónica con potencial de uso en el manejo integrado de la oruga militar tardía Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae). Para tal, fue evaluado la eficiencia de extractos hidroalcohólicos de 15 especies vegetales que se son de la región. Los extractos fueron producidos a partir de las hojas, o de la cáscara, o de liana de las plantas. La eficiencia de los extractos (30 mg.mL -1 ) fue evaluada sobre huevos y larvas de 3º instar de S. frugiperda. Se constató una variación de respuesta de la oruga militar tardía entre los extractos hidroalcohólicos. El extracto de la cáscara de Calycophyllum spruceanum (Benth.) Hook. f. ex K. Schum. presentó mayor eficiencia en los huevos, y el extracto de las hojas de Bauhinia forficata Link presentó mayor eficiencia en las larvas. Estos resultados son fundamentales para el manejo de la oruga militar tardía, toda vez que, los efectos nocivos reducen las pérdidas en la producción de maíz en las primeras fases del desarrollo del S. frugiperda. Se concluye que los extractos de C. spruceanum y B. forficata fueron los más eficientes para los huevos y larvas de la oruga militar tardía.Palabras clave: Spodoptera frugiperda, insecticidas botánicos, manejo integrado de plagas. ABSTRACTThis study aimed to screen plant species from the Amazon region for the potential to be used in the integrated management of the fall armyworm Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae). For this purpose, the efficiency of the hydroalcoholic extracts of 15 plant species from the Amazon region was evaluated. The extracts were obtained from plant leaves, bark, or vines. The efficiency of the extracts (30 mg·mL −1 ) was evaluated on eggs and third instar larvae of S. frugiperda. A range of reactions of the fall armyworm to the hydroalcoholic extracts was observed. The extract obtained from the bark of Calycophyllum spruceanum (Benth.) Hook. f. ex K. Schum. presented the highest efficiency against the eggs, whereas the extract obtained from the leaves of Bauhinia forficata Link was most efficient against the larvae. These findings are essential for the management of fall armyworms because the deleterious effects in the initial stages of S. frugiperda development significantly reduce maize production. In conclusion, the extracts of C. spruceanum and B. forficata were more efficient for eggs and larvae of the fall armyworm, respectively.

A produção brasileira de grãos na safra de 2006/2007 foi estimada em 130,5 milhões de toneladas, destacando-se entre outras, as culturas de soja, milho, arroz e trigo, sendo estas de grande importância no cenário agrícola do Brasil (Companhia Nacional de Abastecimento -Conab 2008). Mundialmente, a produção de milho chega a 615,92 milhões de toneladas, atrás apenas do trigo (Cocamar 2004).Os insetos causam freqüentemente danos extensivos aos grãos armazenados e aos produtos destes grãos. As perdas quantitativas podem atingir 5-10% nas regiões temperadas e 20-30% nas regiões tropicais (Haque et al. 2000). De acordo com Silva et al. (2007) ). Countless problems due to the use of chemical insecticides for the control of pests in stored grains have been observed. In order to minimize these problems, alternative measures have been developed, including the use of botanical insecticides. This work was carried out with the objective of evaluating the effect of the essential oil of Tagetes patula L. on, Sitophilus zeamais (Mots., 1855) in corn kernels in laboratory conditions. The T. patula essential oil was obtained through hidrodestilation with the Clevenger device. The chemical characterization of the compounds found in the essential oil of T. patula was carried by gas chromatography connected to the mass spectrometer. The compounds found were: limonene (37.05%), terpinolene (32.61%), piperitone (14.40%), neophitadiene (5.91%), sabinene (2.88%), trans-ocimene (2.02%), beta-cariphilene (1.98%), farnesol (1.84%), and alpha-pinene (1.30%). The insects used in the bio-test were kept under controled temperature and relative humidity environment. Two bioassays were carried out to evaluate the effect of the essential oil of T. patula on the behavior (activity/repellence) and insecticide activity on adults of S. zeamais. The results showed that this essential oil was efficient (concentration of 10 µL) to control adults of S. zeamais adults.
