| sources of error in the estimation of mosquito infection rates used to assess risk of arbovirus transmission. | infection rate is an estimate of the prevalence of arbovirus infection in a mosquito population. it is assumed that when infection rate increases, the risk of arbovirus transmission to humans and animals also increases. we examined some of the factors that can invalidate this assumption. first, we used a model to illustrate how the proportion of mosquitoes capable of virus transmission, or infectious, is not a constant fraction of the number of infected mosquitoes. thus, infection rate is not al ... | 0 | 20519620 |
| mosquitocidal properties of igg targeting the glutamate-gated chloride channel in three mosquito disease vectors (diptera: culicidae). | the glutamate-gated chloride channel (glucl) is a highly sensitive insecticide target of the avermectin class of insecticides. as an alternative to using chemical insecticides to kill mosquitoes, we tested the effects of purified immunoglobulin g (igg) targeting the extracellular domain of glucl from anopheles gambiae (agglucl) on the survivorship of three key mosquito disease vectors: anopheles gambiae s.s., aedes aegypti and culex tarsalis. when administered through a single blood meal, anti-a ... | 0 | 25994632 |
| modeling and biological control of mosquitoes. | models can be useful at many different levels when considering complex issues such as biological control of mosquitoes. at an early stage, exploratory models are valuable in exploring the characteristics of an ideal biological control agent and for guidance in data collection. when more data are available, models can be used to explore alternative control strategies and the likelihood of success. there are few modeling studies that explicitly consider biological control in mosquitoes; however, t ... | 0 | 17853610 |

| malaria transmission blocking immunity and sexual stage vaccines for interrupting malaria transmission in latin america. | malaria is a vector-borne disease that is considered to be one of the most serious public health problems due to its high global mortality and morbidity rates. although multiple strategies for controlling malaria have been used, many have had limited impact due to the appearance and rapid dissemination of mosquito resistance to insecticides, parasite resistance to multiple antimalarial drug, and the lack of sustainability. individuals in endemic areas that have been permanently exposed to the pa ... | 0 | 21881775 |
| larval anopheline mosquito recta exhibit a dramatic change in localization patterns of ion transport proteins in response to shifting salinity: a comparison between anopheline and culicine larvae. | mosquito larvae live in dynamic aqueous environments, which can fluctuate drastically in salinity due to environmental events such as rainfall and evaporation. larval survival depends upon the ability to regulate hemolymph osmolarity by absorbing and excreting ions. a major organ involved in ion regulation is the rectum, the last region for modification of the primary urine before excretion. the ultrastructure and function of culicine larval recta have been studied extensively; however, very lit ... | 0 | 18805805 |
| the remarkable journey of adaptation of the plasmodium falciparum malaria parasite to new world anopheline mosquitoes. | plasmodium falciparum originated in africa, dispersed around the world as a result of human migration and had to adapt to several different indigenous anopheline mosquitoes. anophelines from the new world are evolutionary distant form african ones and this probably resulted in a more stringent selection of plasmodium as it adapted to these vectors. it is thought that plasmodium has been genetically selected by some anopheline species through unknown mechanisms. the mosquito immune system can gre ... | 0 | 25185006 |

| results of fenitrothion selection of culex pipiens fatigans wied. and anopheles albimanus wied. | laboratory selection of culex pipiens fatigans (=c. quinquefasciatus) and anopheles albimanus by fenitrothion pressure for 30 and 25 generations, respectively, resulted in only 2.2-fold and 1.1-fold increases in tolerance to this compound. cross-resistance to arprocarb in culex increased 12.2-fold but smaller increases in tolerance to fenthion, malathion, ddt, and dieldrin, may be manifestations of vigour tolerance. since the essential conditions for selection are believed to have been fulfilled ... | 1969 | 5306322 |

| population patterns of anopheles albimanus and their significance to malaria abatement. | data obtained between 1967 and 1972 on naturally occurring populations of a. albimanus in el salvador were used to construct 24-hour and seasonal patterns of activity for the species. the resulting patterns are discussed in terms of control implications, and specific examples are given to relate the importance of a knowledge of population dynamics to the success of conventional and alternative methods of anopheline control in malaria abatement programmes. a retrospective view of a successful fea ... | 1974 | 4548395 |
| recent developments in methods of mosquito control. | since residual insecticide spraying in domiciles does not sufficiently control some species of anophelines to halt malaria transmission, alternate methods of control have been investigated. these include ultra-low-volume (ulv) sprays or aerosols, the release of sterile males to suppress or eradicate populations, and the use of diseases or parasites to interfere with transmission or to reduce populations of mosquitos. the ulv aerial sprays gave practical control of anopheles albimanus in haiti an ... | 1974 | 4548396 |

| a prospective study of the effects of ultralow volume (ulv) aerial application of malathion on epidemic plasmodium falciparum malaria. i. study design and perspective. | a large-scale prospective study was designed to test the effects of aerial ultralow volume (ulv) application of malathion on epidemic plasmodium falciparum malaria. the study was conducted during 1972 to 1973, in the miragoane valley of haiti, an area having annual anticipated outbreaks of malaria, which allowed prospective assessment. spraying of malathion at a dosage of 4.5 fluid ounces per acre reduced populations of adult anopheles albimanus to less than 1% of prespray levels and interrupted ... | 1975 | 1091167 |
| a prospective study of the effects of ultralow volume (ulv) aerial application of malathion on epidemic plasmodium falciparum malaria. ii. entomologic and operational aspects. | in a large-scale study in the miragoane valley of haiti, designed to test the effects of aerial ultralow volume (ulv) malathion on epidemic plasmodium falciparum malaria, spray operations resulted in an immediate and sharp decline in numbers of the vector, anopheles albimanus. the adult population of this mosquito remained at less than 1% of previous levels until several weeks after a 50-day spray period (27 october-16 december 1972) during which six cycles were completed. the study area offered ... | 1975 | 1091168 |
| a prospective study of the effects of ultralow volume (ulv) aerial application of malathion on epidemic plasmodium falciparum malaria. iv. epidemiologic aspects. | in the miragoane valley of haiti a consistent pattern in the incidence of plasmodium falciparum malaria over a 10-year period made it possible to predict an annual outbreak and perform a prospective study to test the effects of aerial ultralow volume (ulv) malathion on epidemic levels of this disease. at the end of october 1972, after epidemic levels (100 cases/month/10,000 population) had been reached, spray operations were begun. the first spray cycle produced a sharp and immediate drop in pop ... | 1975 | 1091170 |
| natural infections of anopheles albimanus with plasmodium in a small malaria focus. | entomologic surveys conducted in a small village in an area of known high malaria transmission in el salvador yielded a high rate of infection in anopheles albimanus collected inside houses in which cases of malaria had occurred. of 324 specimens dissected, 12 were found to harbor sporozoites or oocysts. this is in contrast to prior reports of extremely low infection rates in collections of this species from malarious areas, and suggests that under some circumstances a. albimanus does meet the c ... | 1975 | 1098498 |
| results of spraying with ultra-low-volume malathion at ground level in panama city. | several ultra-low-volume (ulv) sprayings of technical malathion (95 per cent) were carried out in panama city. their purpose was to find out how useful this ulv technique could be in helping to combat mosquitoes, especially aedes aegypti. two residential areas were selected as sites for the trials. one of these was san francisco, a district near the shoreline of the bay of panama with many individual houses and a few tall buildings. the other was el cangrejo, a district further inland containing ... | 1975 | 1212538 |
| analysis of the principal problems impeding normal development of malaria eradication programs. | the problems currently impeding the advance of anti-malaria programs in the americas fall into several different categories. these include vector resistance to insecticides, parasite resistance to chloroquine, human behavior patterns which promote human/vector contact or reduce the impact of control efforts, and developments affecting operation, administration, and financing of the control program itself. vector resistance, of course, may be either physiological, behavioral, or both. with regard ... | 1975 | 1240013 |
