| relative susceptibility of some common mosquito vector larvae to synthetic insecticidal compounds in north-western rajasthan. | relative susceptibility of three important mosquito vector larvae viz., anopheles stephensi, aedes aegypti and culex quinquefasciatus, prevalent in the arid region was determined against four organophosphates (malathion, fenitrothion, fenthion, temephos) and three synthetic pyrethroid (alphamethrin, deltamethrin and fanvalerate) compounds. studies were carried out on late 3rd or early 4th instar larvae of these species using standard who technique. based on concentration mortality data lc50 and ... | 2007 | 18405120 |
| evaluation of larvicidal efficacy of solanum xanthocarpum storage against vector mosquitoes in north - western rajasthan. | efficacy of the methanol extracts from fruits without seeds, whole yellow ripe fruits and seeds of the plant solanum xanthocarpum was evaluated against larvae of anopheles culicifacies, anopheles stephensi, aedes aegypti and culex quinquefasciatus, the important vector mosquitoes prevalent in the arid region. experiments were carried out on late 3rd or early 4th instar larvae of these mosquitoes using standard who technique. 24 and 48 hr lc50 and lc90 values along with their fiducial limits, reg ... | 2009 | 20143723 |
| severe and complicated malaria in bikaner (rajasthan), western india. | severe and complicated malaria is an important cause of mortality in plasmodium falciparum infection. we describe in this study the details of 532 cases of such syndromes admitted to hospital during an outbreak of malaria between september-december 1994. increase in the annual rain fall, collection of water around indra gandhi canal, forestation of shrubs around it and migration of labor, adaptation of anopheles stephensi to desert climate and favorable breeding of an. culicifacies in the areas ... | 1997 | 9444003 |
| current status of anopheles stephensi response to various insecticides in some areas of the thar desert. | investigations on the current response of a. stephensi. to six insecticides viz. ddt, dieldrin, malathion, fenitrothion, propoxur and permethrin, were carried out in 3 districts i.e. barmer, jodhpur and pali, of the thar desert. the species was found resistant to ddt and dieldrin, partially resistant to malathion and susceptible to fenitrothion, propoxur and permethrin. dieldrin and malathion resistance has been detected for the first time in the thar desert. lethal concentrations (lc50 & lc95) ... | 1996 | 8707370 |
| efficacy of different organophosphate and synthetic pyrethroid insecticides to the larvae of malaria vector anopheles stephensi, liston. | evaluation of the potency of four organophosphate (op) (malathion, fenthion, fenitrothion and temephos) and two synthetic pyrethroid (sp) compounds (cypermethrin and deltamethrin) was carried out against larvae of anopheles stephensi, the major malaria vector in district bikaner (rajasthan). different concentrations supplied by who were used for determining the percent mortalities. lc50 values as calculated by probit analysis were 1.2740, 0.0600, 0.0405, 0.0046, 0.0019 and 0.0016 mg/l respective ... | 2004 | 15907079 |
