(Submitter supplied) The main objective of this study was to analyze the general midgut transcript profile of Schiustocerca gregaria as well as changes in midgut gene expression during different stages of feeding. We compared three different time points of the digestive process: no active digestion (24 h after feeding), the initial stages of feeding (10 min after feeding) and active digestion in the midgut (2 h after feeding).

(Submitter supplied) RNA-seq was used to study the genes expressed in peculiar glandular organs that transiently appear in insect embryos and are called the pleuropodia. The locust Schistocerca gregaria (Orthoptera) was used as a model. The purpose of the study is to identify the function of these organs. Our results suport the hypothesis (Slifer, 1937) that the pleuropodia secrete enzymes that digest the serosal cuticle before hatching. more...

(Submitter supplied) The migratory locust, Locusta migratoria, is a serious agricultural pest and important insect model to study insect digestion and feeding behavior. The gut is one of the primary interfaces between the insect and its environment. Nevertheless, knowledge on the gut transcriptome of L. migratoria is still very limited. With the development of two EST databases from L. migratoria (whole body and central nervous system (CNS)) and one EST database from Schistocerca gregaria (CNS), an abundance of transcript data was made available for locusts. more...

(Submitter supplied) Protease inhibitors (PIs) are among the most ubiquitous plant defences against herbivorous insects. These inhibitors arrest proteolytic digestion by binding to the proteases in the gut. However, many pest insects have coevolved mechanisms to counteract these effects. While the nature of these counter-defensive strategies has been well described for several insect pests, our understanding of how these responses are triggered and regulated remains limited. more...

(Submitter supplied) DNA methylation is a widely conserved epigenetic modification that is established and maintained by the cooperative activity of DNA methyltransferases. While the complement of DNA methyltransferase genes can vary substantially between animal species, whole-genome methylation analyses have suggested that major features of animal methylomes are widely conserved. We have now used genome-scale bisulfite sequencing to analyze the methylome of the desert locust, Schistocerca gregaria, which represents an economically important pest with a high degree of phenotypic plasticity. more...

(Submitter supplied) Desert locusts (Schistocerca gregaria) show an extreme form of phenotypic plasticity and can transform between a cryptic solitarious phase and a swarming gregarious phase. The two phases differ extensively in behavior, morphology and physiology but very little is known about the molecular basis of these differences. We used our recently generated Expressed Sequence Tag (EST) database derived from S. more...

(Submitter supplied) We recently developed an 'expressed sequence tag' (EST) database derived from the desert locust (Schistocerca gregaria) central nervous system [Badisco L, Huybrechts J, Simonet G, Verlinden H, Marchal E et al. (2011) Transcriptome analysis of the desert locust central nervous system: production and annotation of a Schistocerca gregaria EST database. PLoS One 6: e17274.]. The microarray platform contains probes corresponding to all these S. more...
