The life table is a type of research tool that frequently used in many studies involving population and community ecology. They are the basis for comprehensive pest management, pesticide resistance, predator-prey relationships, biological control, mass-rearing harvesting insects, plant etc. Because morphology, physiology, survival, fecundity, predation/consumption rate most arthropods will vary significantly depending on their developmental stage sex, precise description differentiation...
Vulgarogamasus edurus sp. nov. (Acari: Parasitidae) is described based on females, deutonymphs and males extracted from leaf litter soil in Ami, Ibaraki Prefecture, Japan. Morphological differences between the new species its closely related species, fujisanus (Ishikawa, 1972), are recorded examination of type materials. Information about parasitid mites reported Japanese literature reviewed, a key to provided.
Cardinium bacteria, members of the phylum Cytophaga-Flavobacterium-Bacteroides (CFB), are intracellular bacteria in arthropods that capable inducing reproductive abnormalities their hosts, which include parasitic wasps, mites, and spiders. A high frequency infection was detected planthoppers (27 out 57 species were infected). also found spider mites (9 22 Frequencies double by Wolbachia (Alphaproteobacteria manipulating reproduction hosts) disproportionately but not mites. new group...
A new species Oligonychus neocastaneae sp. nov. is described and illustrated from Castanea crenata Sieb. et Zucc. (Fagaceae). The closely resembles castaneae Ehara Gotoh, 2007, which inhabits the same host plant, crenata, but mainly differs by aedeagus in having a longer distal portion forms small sigmoid acuminate tip, instead of shorter ends truncate tip. Several differences were also observed between two leg setal counts tarsus II male female; number tactile setae solenidia (in...
Abstract The two‐spotted spider mite, Tetranychus urticae Koch, occurs in two colour forms greenhouses the Netherlands: a red form on tomato and green cucumber. evolutionary status of these strains was analysed by studying genetic differentiation, host plant preference, mate choice. Males strain preferred female (30 h‐old) teleiochrysales from same to those cucumber strain, independent plants (tomato, cucumber, bean) which were placed. In contrast, males not selective. Y‐tube olfactometer,...
The spider mite sub-family Tetranychinae includes many agricultural pests. internal transcribed spacer (ITS) region of nuclear ribosomal RNA genes and the cytochrome c oxidase subunit I (COI) gene mitochondrial DNA have been used for species identification phylogenetic reconstruction within Tetranychinae, although they not always successful. 18S 28S rRNA should be more suitable resolving higher levels phylogeny, such as tribes or genera because these evolve slowly are made up conserved...
ABSTRACT Using a combination of the cytochrome oxidase subunit I gene (COI) and internal transcribed spacer (ITS) sequence information, cross-breeding, morphological criteria, taxonomic status Tetranychus takafujii was reassessed. Described from Japan very close to evansi, only male empodium II separated two species. Six T. evansi samples collected in Brazil, France, Kenya, Spain (including Canary Islands), Taiwan, previously species-identified as takafujii, were examined. DNA sequences...
Spider mites are difficult to identify because they very small and have a limited number of diagnostic characters. Most species the spider mite genus Tetranychus in Japan morphologically similar, differing only diameter aedeagal knob males. Because this contains many important pests, unambiguous identification is crucial for effective pest management quarantine procedures. DNA-based methods could complement morphological methods. We examined whether be identified by DNA sequences using...
Cytoplasmic incompatibility (CI) has been proposed as a major mechanism by which certain strains of Wolbachia to invade and persist in host populations. However, mechanisms that underlie the invasion persistence non-CI are less well understood. Here, we established spider mite Tetranychus phaselus population multiply infected Cardinium two distinct lineages Wolbachia, designated wCon wOri, study forces driving spread strain wOri. Interestingly, found wOri provided longevity advantage its...
Abstract A variety of volatile phenylpropenes, C 6 ‐C 3 compounds are widely distributed in the plant kingdom, whereas prenylated phenylpropenes limited to a few species. In this study, we analysed profiles from I llicium anisatum leaves and identified two O ‐prenylated 4‐allyl‐2‐methoxy‐1‐[(3‐methylbut‐2‐en‐1‐yl)oxy]benzene [ ‐dimethylallyleugenol ( 9 )] 5‐allyl‐1,3‐dimethoxy‐2‐(3‐methylbut‐2‐en‐1‐yl)oxy]benzene ‐dimethylallyl‐6‐methoxyeugenol 11 as major constituents. The...
