Larval competition and genetic diversity in Tribolium castaneum [PDF]

Genetics Selection Evolution, 1993
Compared the survival of sib groups and random groups of larvae of flour beetle maintained at high population density. Random groups survived longer, related to a higher early mortality, which reduced competition in the long run in these groups. A clear increase in between-group variability for survival was found in the sib groups, implying the ...

Single‐cell sequencing reveals potential novel insights into appendage‐patterning and joint‐development in a spider

Developmental Dynamics, EarlyView.
Abstract Background Jointed appendages represent one of the key innovations of arthropods, and thus understanding the development and evolution of these structures is important for the understanding of the evolutionary success of Arthropoda. In this paper, we analyze a cell cluster that was identified in a previous single‐cell sequencing (SCS ...

Noncanonical Nucleotides in the Genome Around the Maternal‐Zygotic Transition

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
In this paper, Kazzazi et al. provide a comprehensive review of the dynamics of nonconventional nucleotides in the genome during early developmental stages, hypothesizing a potential role for these nucleotides in the activation of the zygotic genome. ABSTRACT From the very moment of fertilization and throughout development, the cells of animal embryos ...

Morphology, histology, and chemistry of the wings of Tribolium castaneum and Tribolium confusum (Coleoptera: Tenebrionidae)

Journal of Basic and Applied Zoology, 2019
Background Insect wings are an excessively diverse structures, which have fascinated scientist for centuries. Coleoptera is the largest order in the insect group and the most successful animal on earth (Nature Communications 9(205):1–11, 2018).

Temperature stressed males are less attractive to female red flour beetles [PDF]

, 2018
Male red flour beetles (Tribolium castaneum) are shown to attract females through an aggression pheromone that may be altered due to varying degrees of stress (Wade, 1984).

New ‘stimuli-enriched’ laboratory bioassay used to identify improved botanical repellent treatment, Lem-ocimum, to control the stored-grain pest Tribolium castaneum [PDF]

, 2015
A laboratory study of Tribolium castaneum, a major pest of stored grain, was conducted to develop a more efficient and effective ‘choice’ bioassay for identification of new repellent botanical treatments.

DISRUPTIVE SELECTION AND ASSORTATIVE MATING INTRIBOLIUM CASTANEUM [PDF]

Evolution, 1981
Disruptive selection (sometimes called diversifying selection) has been defined as simultaneous selection for more than one optimum phenotype within a single population (Mather, 1955). It is usually interpreted to mean favoring the extreme phenotypes of a quantitative character at the expense of those near the mean; however, the term can also apply to ...

Calpain Proteases and the Evolving Signaling Network in Insect Embryonic Patterning

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
Insect embryonic Dorsal‐Ventral (DV) patterning relies on the BMP and Toll pathways to different extents. Calcium‐dependent cystein proteases of the Calpain family also exert an important function to pattern the DV axis. In Drosophila, Calpain A cleaves the Cactus/IkappaB inhibitor and modifies Toll signals in ventral regions of the embryo. In Rhodnius

A genomic approach to the study of Tribolium castaneum genetics, development & evolution [PDF]

, 2004
During the last decade, Tribolium castaneum has become the insect of choice for comparative genetics and developmental studies outside of drosophilids. Until recently, most molecular studies have focused on the comparative analysis of early development ...
