| biological studies of oligonychus punicae (acari: tetranychidae) on grapevine cultivars. | life cycle, fecundity and longevity of the avocado brown mite, oligonychus punicae (hirst), were studied on six grapevine cultivars (tucupita, villanueva, red globe, sirah, sauvignon and chenin blanc), under laboratory conditions at 27 +/- 2 degrees c, 80 +/- 10% rh, and l12:d12 photoperiod. mite-infested leaves were collected from vineyards, placed in paper bags and taken to the laboratory. a laboratory mite culture was established using the grape cultivar criolla negra as host plant. to elucid ... | 2008 | 18483791 |
| contrasting effects of geographical separation on the genetic population structure of sympatric species of mites in avocado orchards. | oligonychus punicae and oligonychus perseae (acari: tetranychidae) are the most important mite species affecting avocado orchards in mexico. here we used nucleotide sequence data from segments of the nuclear ribosomal internal transcribed spacers (its1 and its2) and mitochondrial cytochrome oxidase subunit i (coi) genes to assess the phylogenetic relationships between both sympatric mite species and, using only its sequence data, examine genetic variation and population structure in both species ... | 2014 | 24871093 |
| differential host plant-associated genetic variation between sympatric mite species of the genus oligonychus (acari: tetranychidae). | adaptation to different host plants can lead to host-associated differentiation (had). the mites oligonychus perseae and oligonychus punicae have a broad range of host plants, but, to date, records of them coexisting sympatrically had only been reported on avocado. however, our field observations showed both species coexisting on host plants other than avocado. the lack of previous records of these mites on the host plants studied here suggests only recent divergence to new host plant species. p ... | 2017 | 28087579 |
