| transcriptome and difference analysis of fenpropathrin resistant predatory mite, neoseiulus barkeri (hughes). | several fenpropathrin-resistant predatory mites have been reported. however, the molecular mechanism of the resistance remains unknown. in the present study, the neoseiulus barkeri (n. barkeri) transcriptome was generated using the illumina sequencing platform, 34,211 unigenes were obtained, and 15,987 were manually annotated. after manual annotation, attentions were attracted to resistance-related genes, such as voltage-gated sodium channel (vgsc), cytochrome p450s (p450s), and glutathione s-tr ... | 2016 | 27240349 |
| insight into the feeding behavior of predatory mites on beauveria bassiana, an arthropod pathogen. | interactions between fungal entomopathogens and pest predators are particularly relevant in control of agricultural insect pests. in a laboratory study, we confirmed that the predatory mite, neoseiulus barkeri, exhibited feeding behavior on the entomopathogenic fungus beauveria bassiana conidia through dna extracts. using transmission electron microscopy, we determined that the majority of conidia found in the mite gut tended to dissolve within 24 h post ingestion, suggesting that the conidia ha ... | 2016 | 27041703 |

| functional and numerical responses of three species of predatory phytoseiid mites (acari: phytoseiidae) to thrips flavidulus (thysanoptera: thripidae). | phytoseiid mites are considered the most effective natural enemies of pest mites. they also have been shown to attack pest thrips. it is unknown, however, whether phytoseiid mites can reduce high densities of thrips flavidulus (bagnall). we addressed this question by the study of functional and numerical responses. the aim of this research was to evaluate the potential predation success of the adults of three predatory mites, neoseiulus cucumeris (oudemans), neoseiulus barkeri (hughes), and euse ... | 2014 | 27193954 |
| mites associated with stored products in greece. | a faunistic survey of mites was conducted in many product stores during a 6-year study period, 2000-2005, in greece. a total of 1,073 samples were taken from 34 greek counties. the survey was carried out on grains (wheat, maize, oat, barley), flour, bran, manufactured agricultural foodstuffs, dried fruits (figs, raisins), residues and dust, stored in varying quantities in five types of storage facilities (stores of agricultural cooperative unions, farm stores, commercial stores, flour mills and ... | 2008 | 18379887 |
| an entomopathogenic strain of beauveria bassiana against frankliniella occidentalis with no detrimental effect on the predatory mite neoseiulus barkeri: evidence from laboratory bioassay and scanning electron microscopic observation. | among 28 isolates of beauveria bassiana tested for virulence against f. occidentalis in laboratory bioassays, we found strain sz-26 as the most potent, causing 96% mortality in adults at 1×10(7) ml(-1)conidia after 4 days. the effect of the strain sz-26 on survival, longevity and fecundity of the predatory mite neoseiulus (amblyseius) barkeri hughes were studied under laboratory conditions. the bioassay results showed that the corrected mortalities were less than 4 and 8% at 10 days following in ... | 2014 | 24454744 |
| feeding on beauveria bassiana-treated frankliniella occidentalis causes negative effects on the predatory mite neoseiulus barkeri. | the entomopathogenic fungus beauveria bassiana and the predatory mite neoseiulus barkeri are both potential biocontrol agents for their shared host/prey frankliniella occidentalis. the combination of the two agents may enhance biological control of f. occidentalis if the fungus does not negatively affect n. barkeri. this study evaluated the indirect effects of b. bassiana strain sz-26 on n. barkeri mediated by f. occidentalis using the age-stage, two-sex life table. when fed on the first instar ... | 2015 | 26153532 |
