The mevalonate pathway and the synthesis of juvenile hormone in insects.
The data suggest that the mevalonate pathway in insects can best be interpreted in terms of coordinated regulation, in which regulators act in parallel to a number of enzymes, as occurs in the cholesterol-driven pathway in vertebrates.
Beyond Drosophila: RNAi in vivo and functional genomics in insects.

The increasing availability of insect genomes has revealed a large number of genes with unknown functions and the resulting problem of how to discover these functions. The RNA interference (RNAi)…
Persistence of double-stranded RNA in insect hemolymph as a potential determiner of RNA interference success: evidence from Manduca sexta and Blattella germanica.
The vitellogenin of the honey bee, Apis mellifera: structural analysis of the cDNA and expression studies.
Screening of antifeedant activity in brain extracts led to the identification of sulfakinin as a satiety promoter in the German cockroach. Are arthropod sulfakinins homologous to vertebrate…
The feeding cycle of the adult female cockroach Blattella germanica parallels vitellogenesis. The study of the mechanisms that regulate this cycle led us to look for food-intake inhibitors in brain…
Evolution on a shaky piece of Gondwana: is local endemism recent in New Caledonia?
A molecular phylogenetic approach is used to answer the question of whether the diversification of the Neocaledonian cockroach genus Angustonicus belonging to the subfamily Tryonicinae from Australia and New Caledonia is less than two million years old or recent diversifications after Tertiary geological catastrophic events.
The MEKRE93 (Methoprene tolerant-Krüppel homolog 1-E93) pathway in the regulation of insect metamorphosis, and the homology of the pupal stage.
Hemimetabolous genomes reveal molecular basis of termite eusociality
Dramatic adaptive changes in genes underlying the production and perception of pheromones confirm the importance of chemical communication in the termites and provide insights into the evolutionary signatures of termite eusociality.
Functions of the ecdysone receptor isoform-A in the hemimetabolous insect Blattella germanica revealed by systemic RNAi in vivo.
Systemic RNAi of the cockroach vitellogenin receptor results in a phenotype similar to that of the Drosophila yolkless mutant
The cloning of the VGR cDNA from Blattella germanica is reported, as well as the first functional analysis of VgR following an RNA interference (RNAi) approach, which leads to a phenotype characterized by low yolk content in the ovary and high vitellogenin concentration in the haemolymph.
