Abstract

The objective of this research was to determine the genetic variability of Spodoptera frugiperda Smith & Abbot (Lepidoptera: Noctuidae) larvae from populations collected on maize (Poales: Poaceae) crops from several locations (Sinaloa, Jalisco, Coahuila, and Durango) in Mexico grown under various types of pest management using inter-simple sequence repeats (ISSR) type molecular markers. These ISSR markers amplified 105 loci, with 92.59% being polymorphic, which genetically characterized these populations and related this variability with factors such as pest control management. The most divergent population was from Tlajomulco, Jalisco. This location had the most intense use of chemical insecticides with diverse modes of action, which may account for much of the difference in genetic variability observed among sites in this study.

 

Sumario

El objetivo de esta investigación fue estudiar la variabilidad genética de gusano soldado Spodoptera frugiperda Smith & Abbot (Lepidóptera: Noctuidae) a partir de larvas de poblaciones recolectadas en cultivos de maíz (Poales: Poaceae) de distintas localidades (Sinaloa, Jalisco, Coahuila y Durango) de Mexico bajo diferentes tipos de manejo del cultivo, utilizando marcadores moleculares tipo ISSR. Estos marcadores amplificaron un total de 105 loci, de los siendo el 92.59% polimórficos, lo cual permitió caracterizar las poblaciones genéticamente y relacionar esta variabilidad con factores como estrategias de control de la plaga. La población más diferenciada, población 7, fue la de Tlajomulco, Jalisco; la localidad con un uso más intensivo de insecticidas químicos con diversos modos de acción, lo que puede explicar gran parte de las diferencias de variabilidad genética observada entre sitios en este estudio.
