Little work has been done on large-scale patterns of stream insect richness in China. We explored the influence of climatic and catchment-scale factors on stream insect (Ephemeroptera, Plecoptera, Trichoptera; EPT) richness across mid-latitude China. We assessed the predictive ability of climatic, catchment land cover and physical structure variables on genus richness of EPT, both individually ...
Wolbachia is a genus of bacterial endosymbionts that impacts the breeding systems of their hosts. Wolbachia can confuse the patterns of mitochondrial variation, including DNA barcodes, because it influences the pathways through which mitochondria are inherited. We examined the extent to which these endosymbionts are detected in routine DNA barcoding, assessed their impact upon the insect sequen...
A new genus, Regiocrella, is described with two species, R. camerunensis and R. sinensis, based on specimens collected in Cameroon and China. Both species are parasitic on scale insects (Coccidae, Homoptera). Morphological and molecular evidence place the new genus in the Clavicipitaceae (Hypocreales), despite its combination of characters that are atypical of that family; Regiocrella is charac...
objective(s) lipocalin 2 (lcn2) is a 25-kda glycoprotein that has initially been extracted from neutrophil granules. expression of lcn2 is induced under various pathophysiological conditions. it is also known as an early marker of kidney and heart injury. high-level expression of recombinant lcn2 neutrophil gelatinase-associated(ngal) in insect cells was the aim of this study. materials and met...
In the last decades, several expeditions were organized in Europe by the researchers of the Hungarian Natural History Museum to collect snails, aquatic insects and soil animals (mites, springtails, nematodes, and earthworms). In this study, scale insect (Hemiptera: Coccomorpha) specimens extracted from Hungarian Natural History Museum soil samples (2970 samples in total), all of which were coll...
The adults of diamondback moth, Plutella xylostella L, are known to have been transoceanic migrants in Europe since ancient times. The insect, which has its origin in Asia Minor, spread to other parts of the world with the spread of the cultivation of its host, the crucifers, and by using its own migrational abilities over long distances. Several large scale transoceanic migrations have been re...
Associations between biological traits of animals and climate are well documented by physiological and local-scale studies. However, whether an ecophysiological phenomenon can affect large-scale biogeographical patterns of insects is largely unknown. Insects absorb energy from the sun to become mobile, and their colouration varies depending on the prevailing climate where they live. Here we sho...
At the liquid-air interface, if there exist any moving disturbances, like a water-walking insect or just a simple pressure source, it will generate capillary-gravity waves [1-4]. The restoring force in this picture is a combination of the gravity and surface tension. And since the disturbance expends a power to generate these waves, it will experience a drag, known as the wave resistance [5]. S...
The reconstruction of large-scale nervous systems represents a major scientific and engineering challenge in current neuroscience research that needs to be resolved in order to understand the emergent properties of such systems. We focus on insect nervous systems because they represent a good compromise between architectural simplicity and the ability to generate a rich behavioral repertoire. I...
