Lepido-DB is a centralized bioinformatic resource that was first developed to facilitate the comparative genomics of two major lepidopteran pests, the noctuid moths Helicoverpa armigera and Spodoptera frugiperda, by the analyzis of syntenic relationships and genome rearrangements of 15 pairs of BACs sequences and their corresponding colinear...

Background: Parasitic wasps constitute one of the largest group of venomous animals. Although some physiological effects of their venoms are well documented, relatively little is known at the molecular level on the protein composition of these secretions. To identify the majority of the venom proteins of the endoparasitoid wasp Chelonus...

Relics of ancient infections are abundant in eukaryote genomes, but little is known about how they evolve when they confer a functional benefit on their host. We show here, for the first time, that the virus-like particles shown to protect Venturia canescens eggs against host immunity are derived from a nudivirus genome incorporated by the...

Background Spodoptera frugiperda (Noctuidae) is a major agricultural pest throughout the American continent. The highly polyphagous larvae are frequently devastating crops of importance such as corn, sorghum, cotton and grass. In addition, the Sf9 cell line, widely used in biochemistry for in vitro protein production, is derived from S....
