摘要
秋粘虫(Spodoptera frugiperda, J.E. Smith)是哥伦比亚玉米作物的重要害虫。了解其种群在转基因植物方面的波动,可以实施监测计划和及时有效的管理行动。本研究的目的是建立2014-2016年哥伦比亚Tolima El Espinal地区30F35R和30F35HR (Cry1F内毒素转基因)杂种S. frugiperda种群消长情况。以每年羽化后每线性米幼虫数和每个杂交种幼虫数为指标,分5个生长周期累积至20、40、60、80和104 d。采用线性混合模型对结果进行统计比较。另一方面,计算了两个虚拟变量,计算了幼虫的存在和损害。以出席(1)和缺席(0)为指标,构建纵向logistic预测模型。杂种30F35R幼虫累积量较大(6.79±0.20);然而,转基因基因型30F35HR也记录了幼虫的存在(4.24±0.20),推断内毒素没有对种群进行完全控制。营养期幼虫数量较多。然而,如果不进行这一阶段的管理,在有Cry1F和没有Cry1F的杂交植株中,作物的损害分别高达52%和72%。这种行为表明,如果不建立庇护区和害虫监测等策略,这些昆虫可能会对含有内毒素Cry1F的植物产生更高的抗性。
Populations of Spodoptera frugiperda (Lepidoptera: Noctuidae) cause significant damage to genetically modified corn crops
The fall armyworm (Spodoptera frugiperda (J.E. Smith)) is an important harmful pest for corn crops in Colombia. Knowing its population’s fluctuation regarding genetically modified plants allows the implementation of monitoring plans and time-effective management actions. The objective of this study was to establish the population’s fluctuation of S. frugiperda during 2014-2016 in the hybrids 30F35R and 30F35HR (genetically modified with the Cry1F endotoxin) in El Espinal, Tolima, Colombia. Accumulations in five growing cycles were carried out until 20, 40, 60, 80, and 104 days with the number of larvae per linear meter after emergence per year and per hybrid. Results were compared statistically using linear mixed models. On the other hand, two dummy variables that reckon the presence of larvae and damage were calculated. With the indicators of presence (one) and absence (zero), a longitudinal logistic prediction model was constructed. Larger accumulation of larvae was registered in the hybrid 30F35R (6.79±0.20); however, the genetically modified genotype 30F35HR also registered the presence of larvae (4.24±0.20), inferring that the endotoxin did not exercise total control over the populations. The vegetative stage showed a higher larval population. However, when this stage is not managed, the crop can show damage up to 52% and 72% in hybrid plants with and without Cry1F, respectively. This behavior suggests that if refuge areas and strategies such as pest monitoring are not established, these insects could generate higher resistances to the plants with the endotoxin Cry1F.

La Revista Facultad Nacional de Agronomía Medellín (RFNA), de la Universidad Nacional de Colombia, Sede Medellín, Facultad de Ciencias Agrarias, es una publicación científica editada desde el año 1939, en formato impreso y digital y de acceso abierto desde la web —sin costo para autores y lectores—. Está orientada a investigadores que crean conocimiento disciplinar y multidisciplinar que articula la ciencia y la tecnología para hacer más productivo el campo a nivel empresarial y de economía campesina. La Revista tiene como objetivo divulgar resultados de investigación mediante artículos originales, inéditos y arbitrados (peer review) de carácter científico que respondan a preguntas específicas y que proporcionen sustento y pruebas a una hipótesis, en aspectos relacionados con las Ciencias Agronómicas, Producción animal, Ciencias Forestales, Ingeniería Agrícola, de Alimentos y otras afines que contribuyan a la solución de los limitantes del agro a nivel nacional, regional e internacional. La Revista recibe y publica, sin ningún costo, artículos en idioma inglés de investigación, revisión, reseñas y cartas al editor. Desde el 2017 la periodicidad de publicación es cuatrimestral, se publican tres números al año con circulación nacional e internacional, en los siguientes períodos: Enero - Abril Mayo - Agosto Septiembre - Diciembre This journal does not charge APCs or submission charges.
