 en Spatial distribution in populations of Oebalus insularis check for this species in other resources Stal (Hemiptera: Pentatomidae) in rice in Calabozo, Guárico State, Venezuela
VIVAS C., Luis Enrique & NOTZ, Armando

Abstract

Studies were conducted on irrigated in three rice fields located at the Rio Guárico Irrigation System in Calabozo, Venezuela, between 2001 and 2004. The objective was to determine the spatial distribution of Oebalus insularis Stal check for this species in other resources in rice fields. The population characteristics were studied by using to s2/x̄ relations, Morissita index and Taylor's power law and Iwao's index. The insect’s field spatial distribution was aggregated or contagious. The population distribution adjusted to the negative binomial mathematical model.

Keywords
rice, Oryza sativa, Oebalus insularis, spatial distribution, models.

 
 es Distribución espacial en poblaciones de Oebalus insularis check for this species in other resources Stal (Hemiptera: Pentatomidae) en el cultivo de arroz en Calabozo, estado Guárico, Venezuela
VIVAS C., Luis Enrique & NOTZ, Armando

Resumen

Se realizaron estudios en campos de arroz con riego ubicados en tres parcelas del Sistema de Riego Río Guárico entre los años 2001 a 2004. El objetivo de este trabajo fue determinar la distribución espacial de la chinche vaneadora del grano de arroz, Oebalus insularis check for this species in other resources Stal., en campos de arroz. Las características poblacionales fueron estimadas mediante la relación s2/x̄, índice de Morissita; la ley de potencia de Taylor, el índice de Iwao y el modelo matemático de la binomial negativa. La chinche en su estado adulto presentó una distribución en el campo del tipo agregada o contagiosa, ajustándose al modelo matemático de la binomial negativa.

Palabras-clave
Oryza sativa, Oebalus insularis, distribución espacial, modelo.
