Pesticide-resistant populations of the predatory mite Metaseiulus (= Typhlodromus or Galendromus) occidentalis (Arthropoda: Chelicerata: Acari: Phytoseiidae) have been used in the biological control of pest mites such as phytophagous Tetranychus urticae. However, the pesticide resistance mechanisms in M. occidentalis remain largely unknown. In other arthropods, members of the glutathione-S-tran...

We present a genome assembly from an individual male Lycaena phlaeas (the small copper; Arthropoda; Insecta; Lepidoptera; Lycaenidae). The sequence is 420 megabases in span. whole of the scaffolded into 24 chromosomal pseudomolecules, with Z sex chromosome assembled. Gene annotation this on Ensembl has identified 12,147 protein coding genes.

We present a detailed analysis of the cell lineage of the tardigrade Thulinia stephaniae with a 4D-microscopy system (3D time-lapse recording). The recording, of the entire development from embryogenesis until hatching, allowed us to analyze the fate of single descendants from early blastomeres up to germ layer formation and tissue development. The embryo undergoes an irregular indeterminate cl...

Avermectins are potent and popular veterinary pharmaceuticals used globally to fight parasites of livestock and humans. By disturbing ion channel transport through the membrane, avermectins are effective against endo- and ectoparasitic round and horsehair worms (Nematoida), insects, or ticks (Arthropoda), but not against Plathelminthes, including flatworms (Trematoda) and tapeworms (Cestoda), o...

Animal tissues need to be properly oxygenated for carrying out catabolic respiration and, as such, natural selection has presumably favored special molecules that can reversibly bind and transport oxygen. Hemoglobins, hemocyanins, and hemerythrins (Hrs) fulfill this role, with Hrs being the least studied. Knowledge of oxygen-binding proteins is crucial for understanding animal physiology. Hr ge...

The distribution of protein kinases activated specifically by low concentrations of guanosine 3’,5’-monophosphate (cyclic GMP) or adenosine 3’,5’-monophosphate (cyclic AMP) in various tissues and species of Arthropoda was studied. The Arthropoda were found to represent a rich source of cyclic GMP-dependent protein kinases. The relative levels of cyclic GMP-dependent and cyclic AMP-dependent pro...
