O presente trabalho teve por objetivo avaliar a eficiência de produtos vegetais no controle de Spodoptera frugiperda (J.E.Smith, 1797) na cultura do milho. Os experimentos foram instalados, nos anos de 2002 e 2004, com a pulverização dos produtos vegetais em cinco tratamentos, e quatro repetições. No ano de 2002, os produtos testados foram: Azadirachta indica A. Juss. (extrato aquoso 2%), e óleo a 1%; Melia azedarach L. (extrato aquoso 2%); Quassia amara L. (extrato aquoso 2%); óleo de nim, Azadirachta indica 1 e 2%. No ano de 2004, os produtos testados foram: A. indica (extrato aquoso 5%), e óleo a 2%, M. azedarach (extrato aquoso 5%), Trichilia pallida Sw. (extrato aquoso 5%). As avaliações, porcentagem de infestação da lagarta-do-cartucho por parcela, foram efetuadas aos três, sete e dez dias após a pulverização dos extratos. Conclui-se que extratos aquosos das plantas A. indica 2%, T.pallida 5%, Q. amara 2% e M. azedarach 2% e 5% e óleo de A. indica 1% e 2% com adição de tenso ativo não iônico, não possuem eficiência necessária como único método de controle da largarta-do-cartucho S. frugiperda em condições de campo. Os produtos começam a afetar o desenvolvimento da lagarta após alguns dias da ingestão das folhas pulverizadas, observado na avaliação efetuada aos sete dias após a aplicação dos extratos.

Spodoptera frugiperda J.E. Smith (Lepidoptera: Noctuidae) is a polyphagous insect pest native to America. Due to its capacity for adaptation and migration, it is currently located in Africa, Asia, and Oceania, where it threatens agricultural crops. The ability of S. frugiperda to develop resistance to insecticides is one of the reasons for the continuous search for more effective, low-cost, and environmentally friendly control products. In the present work, the insecticidal activity of ethanolic and hexane extracts obtained from fresh and dehydrated leaves of Piper auritum Kunth (Piperales: Piperaceae), Piper umbellatum L. (Piperales: Piperaceae), and Cedrela odorata L. (Sapindales: Meliaceae) was studied against first instar larvae of S. frugiperda. The ethanolic extracts of the dehydrated leaves of C. odorata and P. auritum presented insecticidal activity as high (100% mortality at a concentration of 92 mg/cm2) as that obtained with the positive control, Melia azedarach L. (Sapindales: Meliaceae). The GC-MS analysis of the extracts revealed the presence of phytochemicals classified mainly into the groups of monoterpenes, sesquiterpenes, diterpenes, phenylpropanoids, alcohols, and fatty acids. P. auritum grows and propagates rapidly. In addition, due to its low toxicity in mammals and non-target insects, it is a plant with the potential to be used as a botanical insecticide. The exposure of S. frugiperda larvae to low concentrations of ethanolic extract of P. auritum allowed us to observe their biological activity in the development of this insect. The LC50 was 22.1 mg/cm2. At sublethal concentrations (LC21 and LC35) the low fertility of the emerging adults was noticeable.

Sitophilus zeamais (Coleoptera: Curculionidae) and Spodoptera frugiperda (Lepidoptera: Noctuidae) are important economic pests of corn, Zea mays (Poaceae). Psychotria spp. (Rubiaceae) plants are rich in secondary metabolites that could be toxic against such pests. We have screened extracts from four species of Psychotria abundant in the Cerrado (Savannah-type) biome of Brazil for the toxicity to two insects. We found that extracts from leaves and stems had significant effects on the hatching rate, parameters of caterpillar body (weight and length and width of head capsule), repellency, and mortality of these two pests, although the effects varied according to the Psychotria species and plant source (stem or leaf). Extracts of the stems of Psychotria hoffmannseggiana and of Psychotria capitata were more toxic to S. zeamais and the stems of Psychotria goyazensis to S. frugiperda; therefore, such extracts could have the potential for use in integrated pest management schemes.

Studies were carried out to determine the antifeedant activity of extracts of leaves, stems, flowers and fruits of Melia azedarach (L.), the dosage activity responses to the most active extract and the effects of sunlight in the activity persistence to Diabrotica speciosa (Genn.) beetles. Extracts efficiency was determined by evaluating leaf consumption. Insect feeding was deterred by stems, fruits and flowers extracts. Flowers and fruits extracts were the most efficient. Stems extract was in an intermediate position between the two most efficient and the least one (leaf extracts). The most active extract (flowers) was sprayed at concentrations of 0, 1, 2, 3, 4, 5, 6 and 7 g/100 ml. Feeding of D. speciosa on common bean leaves extracts decreased significantly with increasing concentrations of flowers extract, responding in a concentration-dependent manner. Two days after spraying, from 4 to 7 g/100 ml concentrations, feeding was totally inhibited. Four days after spraying, feeding occurred in 4-g/100 ml concentration. When common bean plants exposed to sunlight were sprayed with flowers extract (5-g/100 ml), beetles feeding increased gradually after extract spraying. Results showed that the lack of activity under sunlight conditions was a great limitation to use M. azedarach aqueous extracts.

Secondary plant metabolites have been widely studied as pest control agents. In this paper we report secondary compounds present in Machaerium opacum leaves, as well as the toxicity of different fractions of the extract of this plant to fall armyworm (Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae)) under laboratory conditions. Crude extracts were obtained by means of ethanol. Refractionation was carried out with the solvents hexane, dichloromethane, methanol and ethyl acetate. By means of preliminary phytochemical prospection, starting with the ethanolic extract, flavonoid, triterpene, anthraquinone, coumarin, tannin and steroid compounds were identified. In the ethanolic fractions, triterpene compounds were identified in a mixture (α-amyrin and β-amyrin), as well as lupeol and the acyclic diterpene alcohol, phytol. In methanolic fractions, the flavonoid rutin was found. In the dichloromethane fraction, the flavonoid mucronulatol and its isomer, isomucronulatol, were found. Extracts of M. opacum did not present an antifeedant effect on the larvae of S. frugiperda. However, all fractions of the extracts tested promoted significant antibiosis effects (reduced weight in the larvae and pupa, larval and pupal mortality and prolongation of the adult phase) on the test population of S. frugiperda. Therefore, our results showed the insecticidal potential of leaf extracts of M. opacum against S. frugiperda.

This study evaluates the effects of supercritical carbon dioxide extracts obtained from the fruit of Melia azedarach L. (Meliaceae) on the development of Spodoptera frugiperda J.E. Smith, 1797 (Lepidoptera: Noctuidae), from the larval period until the insect adulthood. For this purpose, a laboratory-scale extraction unit was operated at 60 °C and 200 bar. Larval mortality increased by raising the extract concentration tested: the value of LC50 calculated by Probit analysis was 376.74 mg kg-1, and at a concentration of 5000 mg kg-1, the mortality was 100%. The extract exhibited insect growth inhibitory activity in the higher concentrations (500 mg kg-1, 1000 mg kg-1 and 5000 mg kg-1), due to antifeedant action, resulting in larvae and pupae with mass and body length significantly smaller than the control. At the lowest concentration tested (100 mg kg-1), bioactive effects from the adult stage of the insect were observed, with low viability pupal and adults presenting morphological deformities, hence indicating chronic toxicity effect.
