“…Os danos causados pela lagarta-do-cartucho normalmente são controlados com produtos químicos sintéticos (lima et al, 2008;Brasil, 2010) que, além de aumentar os custos de produção, podem poluir o ambiente e deixar resíduos nos alimentos. Diante disso, há interesse em limitar o uso de produtos fitossanitários, estimulando a implementação do manejo integrado de pragas (Figueredo et al, 2006).…”

RESUMOO objetivo deste trabalho foi estudar os aspectos biológicos de Spodoptera frugiperda (J. E. Smith) e elaborar a tabela de vida de fertilidade deste inseto em cinco linhagens de milho provenientes do Programa de Melhoramento de Milho da Embrapa Clima Temperado. Foram determinadas a duração e sobrevivência das fases de ovo, larva, pré-pupa e pupa, peso de pupas, deformações, longevidade, fecundidade e período de pré-oviposição. A linhagem M89611 não permitiu aos insetos realizarem postura. A duração do período de lagarta, pré-pupa, pupa e adultos foram de 10,67, 1,22, 2,13 e 21,33 dias, respectivamente. O peso de pupa para esta linhagem foi de 0,129 e 0,091g para fêmeas e machos, respectivamente. As deformações foram de 25% e a longevidade de 21,3 dias. S. frugiperda aumentou 20,22 vezes a cada geração para a linhagem M89420, com duração média de 37,26 dias e a razão finita de aumento foi de 1,06668. A linhagem M89611 afeta a biologia de S. frugiperda, enquanto que, a linhagem M89287 proporciona maior viabilidade das fases de desenvolvimento e a linhagem M89420 proporciona a maior taxa líquida de reprodução.PALAVRAS-CHAVE: Noctuidae, lagarta-do-cartucho, resistência, inseto-praga. ABSTRACT BIOLOGY AND FERTITLITY LIFE TABLE OF SPODOPTERA FRUGIPERDA (J.E. SMITH) IN STRAINS OF CORN.The aim of this work was to study the biology of Spodoptera frugiperda (J. E. Smith) and to elaborate the fertility life table of the insect in five strains of corn from the Programa de Melhoramento de Milho da Embrapa Clima Temperado, in Brazil. The following variables were determined: duration and survival of the egg, larval, pre-pupal and pupal phases, pupal weight, deformation, longevity, fecundity and duration of pre-oviposition. The strain M89611 did not allow the insects to lay eggs. The duration of the periods of larvae, pre-pupae, pupae and adults was 10.67, 1.22, 2.13 and 21.33 days, respectively. The pupal weight for this strain was 0.129 and 0.091 g for females and males, respectively. The deformations were 25%, and the longevity was 21.3 days. S. frugiperda increased 20.22 times in each generation for the M89420 strain, with an average of 37.26 days, and the finite rate of increase was 1.06668. The strain M89611 affected the biology of S. frugiperda, whereas the strain M89287 provided greater viability of the development stages, while strain M89420 provided the highest net reproductive rates.

“…(Meliaceae) originated from Asia, is cultivated in several countries of America, Africa, and Aus-tralia and is one of the most important plants with insecticide activity and accentuated action against pests such as S. frugiperda (Lima et al, 2008;Santiago et al, 2008) and mites (Mourão et al, 2004a). Extracts from seeds of A. indica are used as insecticide in water-based and alcoholic solutions (Charbonneau et al, 2007).…”

The control of Lepidoptera pests should be carried out before hatching of their caterpillars to avoid damage to the crops. The aim of this work was to assess the activity of neem (trade name: Natuneem ® , producer: Base Fértil, Chapadão do Sul, Brazil) and pyroligneous extracts (trade name: Biopirol 7M ® , producer: Biocarbo, Itabirito, Brazil) at 10 mL/L (1%) and 20 mL/L (2%) contents on egg masses of different ages of Spodoptera frugiperda Smith (Lepidoptera: Noctuidae) and of Diatraea saccharalis F. (Lepidoptera: Pyralidae) at Embrapa Corn and Sorghum in Sete Lagoas, Minas Gerais State, Brazil. The tests took place in an unbiased casualized design with 12 treatments and four replications. The insecticides were diluted in water, and 0.04 mL of the solution was applied to recently laid and one-and two-day-old eggs of S. frugiperda and D. saccharalis. Caterpillars hatching from recently laid egg masses of S. frugiperda was lower with 2% pyroligneous extract [(0.02 ± 0.00)%]. Recently laid eggs and one-or two-day-old eggs of D. saccharalis presented lower caterpillar hatching with 1% neem extract [(0.00 ± 0.00)%, (0.00 ± 0.00)%, and (1.00 ± 0.01)%] and 2% neem extract [(0.00 ± 0.00)%], compared to 1% pyroligneous extract [(27.30 ± 3.22)%, (28.40 ± 3.32)%, and (37.80 ± 4.14)%] and 2% pyroligneous extract [(42.20 ± 4.49)%, (48.70 ± 4.97)%, and (56.60 ± 5.52)%], respectively. Neem and pyroligneous extracts had impact on hatching of S. frugiperda and D. saccharalis caterpillars.

“…With the application of these insecticides botanicals, the larvae S. frugiperda only caused minimal damage (Oleonim 80 CE ® and Oleonim 50 CE ® : 0.07 and 0.06 larvae/plant) or moderate (Neem oil extract ® and Neem Azal-T/S ® : 25.8-17.5%) on maize plants (Pérez et al, 1997;Lima et al, 2008;Gutiérrez-García et al, 2010), while in our study 11.6% was the percentage of plant damage to corn treated aqueous extract of C. papaya.…”

Each shoot was infested with one first instar larva of S. frugiperda. The variables measured included the percentage of germination, length of the second and fifth leaves, stem diameter and plant height, and the estimation of damage caused by S. frugiperda larvae on maize. The results indicated that vermicompost helped seed germination on a relation 3:1 from black soil and vermicompost, the emergence was 100%, while the emergence with black soil was 80%. The ammonium sulfate increased the length of the second and fifth leaves 89.6% and 160.4% respectively, augmented the stem diameter and the plant height 290.2% and 13.3% respectively, respect to water treatment. The exogenous nitrogen sources stimulate S. frugiperda to cause more damage to the plant, the treatment urea showed 70% of damage, with phosphonitrate 62.3% and with ammonium sulfate 51.8%, when were evaluated without aqueous seed extract of C. papaya. Ammonium sulfate + aqueous extract of C. papaya seeds showed the lowest insect damage to maize with 29.6%.
