| superinfection of cytoplasmic incompatibility-inducing wolbachia is not additive in orius strigicollis (hemiptera: anthocoridae). | cytoplasmic incompatibility (ci) allows the intracellular, maternally inherited bacterial symbiont wolbachia to invade arthropod host populations by inducing infertility in crosses between infected males and uninfected females. the general pattern is consistent with a model of sperm modification, rescued only by egg cytoplasm infected with the same strain of symbiont. the predacious flower bug orius strigicollis is superinfected with two strains of wolbachia, wous1 and wous2. typically, superinf ... | 2011 | 20700141 |
| olfactory responses of the predatory mites (n eoseiulus cucumeris) and insects (orius strigicollis ): to two different plant species infested with onion thrips (t hrips tabaci). | responses of neoseiulus cucumeris (a predatory mite) and the predatory insect orius strigicollis to volatiles associated with two different plant species infested with onion thrips, thrips tabaci, were examined in a y-tube olfactometer. both predators species showed a significant preference for volatiles from infested cucumber leaves without t. tabaci over clean air. however, they were not attracted to volatiles from uninfested cucumber leaves, artificially damaged cucumber leaves, or volatiles ... | 2008 | 18414949 |
| toxicity of the herbicide glufosinate-ammonium to predatory insects and mites of tetranychus urticae (acari: tetranychidae) under laboratory conditions. | the toxicities of the herbicide glufosinate-ammonium to three predatory insect and two predatory mite species of tetranychus urticae koch were determined in the laboratory by the direct contact application. at a concentration of 540 ppm (a field application rate for weed control in apple orchards), glufosinate-ammonium was almost nontoxic to eggs of amblyseius womersleyi schicha, phytoseiulus persimilis athias-henriot, and t. urticae but highly toxic to nymphs and adults of these three mite spec ... | 2001 | 11233107 |
| novel strain of spiroplasma found in flower bugs of the genus orius (hemiptera: anthocoridae): transovarial transmission, coexistence with wolbachia and varied population density. | spiroplasma, a group of small, wall-less, helical, and motile bacteria belonging to the mollicutes, contains species with diverse life histories. to date, all the spiroplasma strains that are known to be transmitted vertically in arthropod lineages belong to either the spiroplasma ixodetis group or the spiroplasma poulsonii group. here, we found that a unique strain of spiroplasma vertically transmitted in predatory flower bugs of the genus orius belongs to the spiroplasma insolitum group, which ... | 2014 | 24337178 |
| fumigant toxicity of plant essential oils to thrips palmi (thysanoptera: thripidae) and orius strigicollis (heteroptera: anthocoridae). | the fumigant toxicity of 92 plant essential oils to adult thrips palmi karny (thysanoptera: thripidae) and orius strigicollis poppius (heteroptera: anthocoridae) was examined by using a vapor phase toxicity bioassay and compared with those of dichlorvos, emamectin benzoate, spinosad, and thiamethoxam, four commonly used insecticides. responses varied according to oil type and insect species. as judged by 24-h lc50 values, pennyroyal oil (2.63 mg/liter air) was the most toxic fumigant and was 23. ... | 2006 | 17066806 |
| fumigant toxicity of basil oil compounds and related compounds to thrips palmi and orius strigicollis. | this study was aimed at assessing the fumigant toxicity to adult thrips palmi (a serious insect pest) and orius strigicollis (a beneficial predator insect) of basil (ocimum basilicum) essential oil compounds and structurally related compounds using vapour-phase toxicity bioassays. | 2015 | 25315807 |
| comparison of demographic parameters and predation rates of orius strigicollis (hemiptera: anthocoridae) fed on eggs of tetranychus urticae (acari: tetranychidae) and cadra cautella (lepidoptera: pyralidae). | orius strigicollis (poppius) is an anthocorid bug with high foraging ability on thrips as well as on mites, and the bug has been considered as a potential biological control agent in taiwan. life table and predation studies of o. strigicollis fed on cadra cautella (walker) and tetranychus urticae (koch) eggs were conducted at 25 ± 1°c. data were analyzed and compared using twosex-mschart and consume-mschart software. o. strigicollis fed on eggs of c. cautella, a substitute prey, showed significa ... | 2016 | 27298426 |
| distribution patterns of wolbachia endosymbionts in the closely related flower bugs of the genus orius: implications for coevolution and horizontal transfer. | vertical transmission is the primary route of the endosymbiont wolbachia for its own spread among invertebrate hosts, but horizontal transmission between different hosts is believed to have occurred multiple times. however, it is not well known how wolbachia commonly spread among closely related hosts. we focused on the closely related species of the minute pirate bugs belonging to the genus orius, which are important biological control agents in agricultural crops because they are the most usef ... | 2012 | 22450512 |
