Male mites (Varroa destructor) perceive the female sex pheromone with the sensory pit organ on the front leg tarsi
Varroa destructor males are attracted by a volatile sex pheromone of female mites. We assume that this pheromone is perceived by the sensory pit organ on the front leg tarsi. To test this hypothesis,Expand
Karyology and sex determination of oribatid mites
In a recent publication, ZHANG, Fu & WANG (2004) reported a karyotype analysis of two species of brachypyline oribatid mites: Brasilobates spinosus Fujita (Protoribatidae, or Haplozetidae) andExpand
Ultrastructural and molecular insights into three populations of Aporrectodea trapezoides (Dugés, 1828) (Oligochaeta, Lumbricidae) with different reproductive modes
Abstract Aporrectodea trapezoides is a widely distributed earthworm, consisting of sexual, pseudogamic and parthenogenetic forms. We sampled individuals from five differently reproducing populations:Expand
Adding to the Reproductive Biology of the Parthenogenetic Oribatid Mite, Archegozetes longisetosus (Acari, Oribatida, Trhypochthoniidae)
The oribatid mite, Archegozetes longisetosus, serves as a chelicerate model organism due to its relatively short life cycle and ease of laboratory culturing. It is a parthenogenetic species and allExpand
With about 10,000 described species and densities reaching 400,000 ind/m2, the Oribatida (without Astigmata) represent the most prevalent group of soil mites. However, with the exception of theirExpand
First cleavages, preblastula and blastula in the parthenogenetic mite Archegozetes longisetosus (Acari, Oribatida) indicate holoblastic rather than superficial cleavage.
The mode of cleavage in the Acari is generalized as superficial or intralecithal, with a preceding phase of total (holoblastic) cleavage, but the knowledge is fragmentary and conclusions have beenExpand
Hindwings of insects as concept generator for hingeless foldable shading systems.
We develop a deployable structure inspired by the Flexagon model of hindwings of insects in general and the hierarchical structure of the wing cuticle of the shield bug (Graphosoma lineatum). Expand
Morphology of the internal reproductive organs of Archegozetes longisetosus Aoki (Acari, Oribatida)
The morphology and three-dimensional organisation of the internal reproductive system of Archegozetes longisetosus is described, using a combination of conventional microscopic methods and theExpand
Ultrastructural aspects of vitellogenesis in Archegozetes longisetosus Aoki, 1965 (Acari, Oribatida, Trhypochthoniidae).
We studied the process of vitellogenesis in the oribatid mite Archegozetes longisetosus using light and electron microscopy. Both vitellogenesis and the formation of the first egg shell occur withinExpand
Some remarks on the cytogenetics of oribatid mites
The behaviour of the meiotic segregations of the parthenogenetic oribatid mite Archegozetes longisetosus Aoki were investigated in maturing oocytes. Data about the meiotic mechanisms inExpand
