Entomologia Experimentalis et Applicata v. 49, no. 3, p. 213-219615172Summary: Population densities of the cicadellid Dalbulus maidis in single-variety maize plantings were compared to densities in mixed-variety plantings at 2 sitesin Nicaragua in 1982. In the site where there were high numbers of D. maidis, densities were significantly lower in mixed stands than would be expected by averaging the densities found in the pure stands of the component varieties. This response to genetic diversity appeared to be due to a behavioural response during the period of colonization or establishment. At the site with low population density, the difference between mixed and pure stands was not significant. At
