Scavenging by spiders (Araneae) and its relationship to pest management of the brown recluse spider.
Abstract
Experiments reported in Sandidge (2003; Nature 426: 30) indicated that the brown recluse spider, Loxosceles reclusa Gertsch & Mulaik, preferred to scavenge dead prey over live prey and that the spiders were not detrimentally affected when fed insecticide-killed crickets. Extrapolations made in subseq...

Abstract
Exotic species have often been introduced into a new country in zoological or botanical gardens or on game and fur farms. When accidentally or deliberately released, these alien species can become invasive and have negative impacts on native plant and animal communities and human activities. This ar...

Abstract
We review studies that address economically optimal control of established invasive species. We describe three important components for determining optimal invasion management: invasion dynamics, costs of control efforts and a monetary measure of invasion damages. We find that a management objective...

The efficacy of trunk treatment with three materials, cotton seed oil, lime and used motor oil, were evaluated for the control of apple clearwing, Synanthedon myopaeformis (Borkhausen) (Lepidoptera: Sesiidae) in an apple orchard during two successive years (2004 and 2005). The weekly total number of...

Neotropical Entomology (39)1 2010
Abstract
An Integrated Pest Management is formulated as a threshold policy. It is shown that when this strategy is applied to a food web consisting of generalist, specialist predators and endemic and pest prey, the dynamics can be stable and useful from the pest control point of view, despite the dynamical c...

Abstract
Nicotinic acetylcholine receptors (nAChRs) are ligand-gated ion channels that mediate fast synaptic transmission in the insect nervous system and are targets of a major group of insecticides, the neonicotinoids. They consist of five subunits arranged around a central ion channeL Since the subunit co...
