Individuals of both dispersal and non-dispersal types (disperser and non-disperser) are found in a population, suggesting that each type has both costs and benefits for fitness. However, few studies have examined the trade-off between the costs and benefits for the types. Here, we artificially selected for walking distance, i.e., an indicator of dispersal ability, in the red flour beetle Tribol...

In the legends for Fig 1 and S1 Fig, the name of the TCAST1 element subfamily Tcast2b is incorrect and should be replaced with Tcast1b. The correct legends are below.

terning genes) differ as compared to Drosophila (Wheeler etal., 2005). We assume that temporal changes in spatial cues might influence neuroblast identity. This mechanism might have contributed to evolutionary changes in arthropod neurogenesis. We are therefore analysing the expression pattern of homologues of the Drosophila neuroblast identity genes (e.g. segment polarity genes, dorso-ventral ...

To investigate gene expression in Tribolium castaneum exposed to Beauveria bassiana, reference genes for qPCR were evaluated. Of these, beta-actin, alpha-tubulin, and RPS6 were not stable. The most stable were ribosomal protein genes, RPS3, RPS18, and RPL13a. Syntaxin1, syntaxin6, and E-cadherin may be appropriate for some experimental systems.

Cyperus articulatus is an insect repellant plant commonly found in Northern Nigeria and used traditionally in pest control. The light petroleum and methanol extracts of the plant's rhizome were evaluated against Tribolium casteneum Hbst (the red flour beetle) using standard techniques. The methanol extract showed more antifeedant property than the light petroleum extract, while both the extract...
