In Vivo Dose-Response Of Insects To Hz-2v Infection, John P. Burand, Christopher P. Rallis Dec 2004

In Vivo Dose-Response Of Insects To Hz-2v Infection, John P. Burand, Christopher P. Rallis

John Burand

Background Hz-2V infection of female Helicoverpa zea moths is manifested as insects that are either sterile "agonadal" individuals with malformed reproductive tissues or fertile asymptomatic carriers which are capable of transmitting virus on to their progeny. Virus infected progeny arising from eggs laid by asymptomatic carrier females may themselves be either sterile agonadals or asymptomatic carriers. Results By injecting virus into female moths, a correlation was established between virus doses administered to the females and the levels of resulting asymptomatic and sterile progeny. Conclusions The results of these experiments indicate that high virus doses produced a higher level of agonadal ...

The Unpredictable Past Of Plasmodium Vivax Revealed In Its Genome, Stephen M. Rich Oct 2004

The Unpredictable Past Of Plasmodium Vivax Revealed In Its Genome, Stephen M. Rich

Stephen M. Rich

Until quite recently, very little information has been available about the genome content and structure of parasitic protozoa. This inadequacy has been rectified by the advent of high-throughput strategies that permit sequencing of whole genomes and enhanced computational capacities that render this information tractable. The current list of complete or near-complete genomes includes some of the greatest scourges of humans and their domesticated companions. Among these miscreants are several members of the genus Plasmodium, the agents of malaria. Scores of species of Plasmodium have been described and comprise pathogens of every major group of terrestrial vertebrates. At present, no less ...

The Dual Role Of Floral Traits: Pollinator Attraction And Plant Defense, Rebecca E. Irwin, Lynn Adler, Alison K. Brody Jan 2004

The Dual Role Of Floral Traits: Pollinator Attraction And Plant Defense, Rebecca E. Irwin, Lynn Adler, Alison K. Brody

Lynn Adler

Plants are under siege from a diversity of enemies that consume both leaf and floral parts. Plants resist damage to leaves in a variety of ways, and we now have a rich literature documenting how plants defend themselves against herbivore attack. In contrast, the mechanisms by which plants resist enemies that consume floral parts or resources are much less known, even though damage to floral tissue usually has tighter links to plant fitness than damage to leaf tissue. Many plants experience nectar robbing, whereby floral visitors remove nectar from flowers, often without pollinating. Nectar robbers can reduce plant fitness to ...
