Spatiotemporal Distribution of Chinavia hilaris (Hemiptera: Pentatomidae) in Peanut-Cotton Farmscapes.

摘要: The green stink bug, Chinavia hilaris (Say) (Hemiptera: Pentatomidae), is a pest of cotton in the southeastern United States, but little known concerning its spatiotemporal distribution agricultural farmscapes. Therefore, C. farmscapes where fields adjoined peanut was examined weekly. Spatial patterns counts were analyzed using SADIE (Spatial Analysis by Distance Indices) methodology. Interpolated maps density used to visualize abundance and crops. For six peanut-cotton studied, frequency (94.8%) significantly higher than (5.2%), nymphs rarely detected peanut, indicating that not source into cotton. Significantly, aggregated spatial distributions Maps local clustering indices depicted patches cotton, mainly at field edges including peanut-to-cotton interface. Black cherry (Prunus serotina Ehrh.) elderberry (Sambucus nigra subsp. canadensis [L.] R. Bolli) grew habitats adjacent crops, captured pheromone-baited bug traps these habitats, most instances, observed feeding on black before colonization revealed colonized near two noncrop hosts. Altogether, findings suggest sources Factors affecting dynamics are discussed.
