Spatial distribution is one of the most characteristic ecological properties of species. Unlike
rates of growth and reproduction, which often vary more between generations within a …

We evaluated the influence of intraguild predation among generalist insect predators on the
suppression of an herbivore, the aphid Aphis gossypii, to test the appropriateness of the …

Implementation of integrated pest management (IPM) is by definition scale-and location-
specific and because these features govern biophysical processes such as dispersal …

Spatial variance of observed measures such as density is no longer viewed as a statistical
annoyance. It is now treated as a biological important quantity that changes value …

1. Two field experiments were conducted to test the hypothesis that the intensity of predation
by a generalist predator on two species of prey changes with the developmental stage of the …

The management of agroecosystems affects intricately linked assemblages of organisms,
and nontarget species are not necessarily unimpacted. We examined the effect of Bt-cotton …

When insect population density varies within the same cotton field, estimation of abundance
is difficult. Multiple population densities of the same species occur because cotton fields …

A complex of hemipterans, especially the tarnished plant bug, Lygus lineolaris (Palisot de
Beauvois)(Hemiptera: Miridae), has become a major target of insecticides in flowering …

The understory is a varied and complex habitat, forming a key layer in the forest ecosystem.
Lawrence (1995) defines the understory as the “vegetation layer between the tree canopy …

The green sharpshooter (DraeculaceXhala minerva [Ball]) and redheaded sharpshooter
(Corneacephala fulgida [Nott.]), important leafhopper vectors of Pierce's disease bacterium …
