| functional and numerical responses of the predatory mite, neoseiulus longispinosus, to the red spider mite, oligonychus coffeae, infesting tea. | functional and numerical responses of the predatory mite, neoseiulus longispinosus (evans) (acari: phytoseiidae) to the red spider mite, oligonychus coffeae nietner (acari: tetranychidae), infesting tea were determined in a laboratory on leaf discs. prey consumption increased with increases in temperature and prey density. handling time decreased and successful attack rate increased with increased temperature. n. longispinosus was more voracious on larvae and nymphs than on adults of o. coffeae. ... | 2012 | 23452011 |
| mechanism of fenpropathrin resistance in red spider mite, oligonychus coffeae (acarina: tetranychidae), infesting tea [camellia sinensis l. (o. kuntze)]. | red spider mite (rsm), oligonychus coffeae (nietner) (acarina: tetranychidae), has gained special attention in view of their widespread occurrence as a pest on tea [camellia sinensis l. (o. kuntze)]. the development of acaricide (fenpropathrin) resistance has been screened in field populations (fps) of rsms from different tea-growing regions of south india and compared with a laboratory-susceptible population (sp) based on toxicity bioassay, detoxifying enzyme activities, analysis of acetylcholi ... | 2017 | 27604837 |
| the red spider mite, oligonychus coffeae (acari: tetranychidae): its status, biology, ecology and management in tea plantations. | oligonychus coffeae nietner (acari: tetranychidae), the red spider mite (rsm), is a major pest of tea (camellia sinensis) in most tea-producing countries. nymphs and adults of rsm lacerate cells, producing minute characteristic reddish brown marks on the upper surface of mature leaves, which turn red in severe cases of infestation, resulting in crop loss. the pest is present on tea all the year round, although numbers vary depending on season. their number increases as the weather warms up and d ... | 2014 | 24705870 |
| life table and predation of neoseiulus longispinosus (acari: phytoseiidae) on oligonychus coffeae (acari: tetranychidae) infesting tea. | life table and predation of the predatory mite neoseiulus longispinosus (evans) on the red spider mite (rsm), oligonychus coffeae (nietner), a major pest of tea in india, were studied in the laboratory. developmental time from egg to adult varied from 4 to 14 days at 30 to 15 °c, respectively; at 35 °c no larva survived. survival of immature stages was more than 94 % at all temperatures. threshold temperature for development of immature stages of females and males was 10 and 9.9 °c, respectively ... | 2013 | 23247399 |
| life table and efficacy of mallada desjardinsi (chrysopidae: neuroptera), an important predator of tea red spider mite, oligonychus coffeae (acari: tetranychidae). | green lacewing, mallada desjardinsi navas, is an important predator of red spider mite, oligonychus coffeae infesting tea. life history, life table and efficacy of m. desjardinsi were determined using red spider mite as prey under laboratory conditions. duration of development of m. desjardinsi recorded was 5.1, 13.8 and 13 days for eggs, larvae and pupae respectively, with an average of 31.9 days from egg to adult emergence. after a mean pre oviposition period of 7.1 days, a single female laid ... | 2013 | 23430022 |
| life table and predatory efficiency of stethorus gilvifrons (coleoptera: coccinellidae), an important predator of the red spider mite, oligonychus coffeae (acari: tetranychidae), infesting tea. | the ladybird beetle, stethorus gilvifrons, is a major predator of the red spider mite, oligonychus coffeae, infesting tea. biology, life table and predatory efficiency of s. gilvifrons were studied under laboratory conditions. its average developmental period from egg to adult emergence was 19.2 days. after a mean pre-oviposition period of 5.3 days, each female laid an average of 149.3 eggs. adult females lived for 117.3 days and males for 41.5 days. the life table of the beetle was characterize ... | 2010 | 19693682 |
