“…The absence of difference between cultivars for DFH10 and DFHF was due to a decrease in the incidence and leaf damage of this pest in later stages of the crop biological cycle, which shows that this insect has a higher incidence in stages prior to flowering in maize (Murúa et al, 2006;Casmuz et al, 2010).…”

“…La ausencia de diferencia entre cultivares para el DFH10 y DFHF, se debió a una disminución en la incidencia y daño foliar de esta plaga en etapas más avanzadas del ciclo biológico del cultivo, lo cual demuestra que este insecto presenta una mayor incidencia en etapas anteriores a la iniciación floral en el maíz (Murúa et al, 2006;Casmuz et al, 2010).…”

ResumenEl gusano cogollero (Spodoptera frugiperda) daña al maíz durante todo el ciclo biológico de la planta; una opción para esta problemática es el desarrollo y utilización de cultivares resistentes; para ello, es necesario conocer el comportamiento genético de las características que inducen esta resistencia. Se evaluó genéticamente la resistencia a S. frugiperda por no preferencia de cultivares de maíz desarrollados con germoplasma nativo de Tamaulipas; en el ciclo otoño-invierno 2014-2015, en Güémez, Tamaulipas, en tratamientos de fertilización y no fertilización se evaluaron seis líneas endogámicas de maíz derivadas de germoplasma nativo, sus cruzas directas y recíprocas y cuatro híbridos comerciales, en un diseño de bloques completos al azar; se realizó un análisis dialélico para determinar efectos maternos, recíprocos, de aptitud combinatoria general y específica; el daño foliar por S. frugiperda se estimó en las etapas de sexta hoja ligulada (DFH6), décima (DFH10) y a floración (DFHF). Hubo menor daño de S. frugiperda en el tratamiento de fertilización comparado con el de no fertilización; también diferencias estadísticas entre cultivares para el DFH6 e interacción significante entre cultivares y tratamientos de fertilización. AbstractThe fall armyworm (Spodoptera frugiperda) damage maize throughout the life cycle of the plant; one option for this problem is the development and use of resistant cultivars; for this, it is necessary to know the genetic behavior of the characteristics that induce this resistance. S. frugiperda resistance was genetically evaluated by no preference of maize cultivars developed with germplasm native of Tamaulipas; in the autumn-winter cycle 2014-2015, in Güémez, Tamaulipas, in fertilization and nonfertilization treatments, six inbred maize lines derived from native germplasm, its direct and reciprocal crosses and four commercial hybrids were evaluated in a complete random block design; a diallel analysis was performed to determine maternal, reciprocal, general and specific combinatorial effects; leaf damage by S. frugiperda was estimated in the stages of the sixth ligulate leaf (DFH6), tenth (DFH10) and flowering (DFHF). There was minor damage of S. frugiperda in the fertilization treatment compared to the non fertilization one; also statistical differences between cultivars for DFH6 and significant interaction between cultivars and fertilization treatments.1330 Rev. Mex. Cienc. Agríc. Vol.8 Núm. 6 14 de agosto -27 de septiembre, 2017 Zoila Reséndiz Ramírez et al.Las cruzas PWL1S3×PWL6S3 y TGL2S3×LlHL5S3 tuvieron efectos de aptitud combinatoria específica negativa; la primera mostró efectos recíprocos significativos debido a efectos maternos de la línea PWL1S3, esto evidencia que la variación existente para esta característica se explica mediante efectos maternos y no aditivos; además, presen DFH6 de S. frugiperda de 0.867 demostrando menor preferencia del insecto en comparación al resto de los cultivares.Palabras clave: Zea mays L., aptitud combinatoria, dialélico, gusano co...

“…The relative importance (RI) of a species takes into account not only its abundance but also its Murúa et al 2006). For each sampled site the relative importance of species was determined using the formula: RI = (n i ⁄n t ) × (m i ⁄m t ) × 100, where n i = number of individuals of species "i", n t = number of individuals of all species, m i = number of samples containing species "i", and m t = total number of samples.…”

“…a espécie apresenta ampla distribuição geográfica ocorrendo desde a américa do sul até américa do Norte, hospedando-se em uma diversidade de plantas. S. frugiperda foi registrada em 80 espécies de plantas pertencentes a 23 famílias diferentes (Pashley 1988;Giolo et al 2002;Fernandes et al 2002;Murúa et al 2006). No Brasil, é considerada uma das principais pragas das culturas do milho e do arroz e recentemente passou a ser uma praga importante da cultura do algodão (Martinelli et al 2006).…”

-In this present study the effect of vegetable extracts obtained from 19 plant species on the development of Spodoptera frugiperda was evaluated. The aqueous extracts were prepared by maceration (4ºC) and infusion (90ºC) at 10%. The experiments were realized under controlled conditions (12h of photophase at 25°C and 70% U.R.) using 100µL of the vegetable extract in the artificial diet fed to 2º instar caterpillars individually identified. In the control samples the vegetable extract was substituted by distilled water. Amongst the medicinal plant species tested, only Lantana camara had no effect on any of the variables analysed. The larval phase was prolonged by the extracts of M. silvestris, C. ensiformes, C. verbenacea, C. zedoaria and C. citratus, while the duration of the pupal phase was extended by the S. officinalis and C. verbenacea mixtures. Reductions in the sizes of the pupa were observed with the use of four of the vegetable species, and the weight was reduced by five species. At this phase in the tests therefore, 16 species were shown to cause anomalies and six produced negative effects on oviposition and fertility. The results indicate that, of the plant species evaluated in this study, 18 interfered in the development of S. frugiperda in various ways and should now be analysed to determine the chemical composition that makes these plant extracts potential insecticides for control of the target species.KeY WorDs -Biological cycle; Plant insecticide; Botanical insecticide; armyworms, Bioassay.resUMo -No presente trabalho foi avaliado o efeito dos extratos vegetais, de 19 espécies de plantas medicinais, no desenvolvimento de Spodoptera frugiperda. Os extratos aquosos foram preparados na forma de macerado (4ºC) e infusão (90ºC) a 10%. Os experimentos foram realizados em condições controladas (12h de fotofase, 25°C e 70% de U.R.), aplicando-se 100 µL do extrato vegetal sobre a dieta artificial, onde lagartas de 2º ínstar foram individualizadas, sendo na testemunha o tratamento substituído por água destilada. Entre as espécies de plantas medicinais testadas, apenas Lantana camara não apresentou efeito sobre ao menos uma das variáveis analisadas. O prolongamento da fase larval ocorreu quando aplicados os extratos de M. silvestris, C. ensiformes, C. verbenacea, C. zedoaria e C. citratus. Quanto à duração da fase pupal observou-se o prolongamento quando utilizados os macerados de S. officinalis e C. verbenacea. Redução no tamanho das pupas ocorreu para quatro espécies vegetais, sendo o peso reduzido para cinco espécies. Nessa mesma fase, 16 espécies provocaram anomalias. Efeitos negativos sobre oviposição e fertilidade foram observados para seis espécies de plantas. Os resultados indicam que 18 espécies, entre as plantas avaliadas nesse estudo, interferem no desenvolvimento de S. frugiperda, as quais poderão ser analisadas quanto à composição química, como potencial inseticida aplicado no controle da espécie-alvo.PALAVRAS-CHAVE -Ciclo biológico; planta inseticida; inseticida botânico; lagarta-do-car...
