release of romanomermis culicivorax for the control of anopheles albimanus in el salvador i. mass production of the nematode.	the mosquito parasite, romanomermis culicivorax, was mass produced for the treatment of 144,000 m2 of anopheles albimanus breeding area in el salvador. the production of the necessary inoculum required the exposure of 1.6 x 10(6) first-instar culex p. quinque-fasciatus larvae to 137 x 10(6) preparasites (1:14 ratio) each week for 6 weeks. the method employed produced an average 13.7 g (ca. 2,200/g) of postparasitic nematodes per rearing tray (20,000 mosquitoes), a total of 6,392 g (14.1 lb) for ...	1978	727330
release of romanomermis culicivorax for the control of anopheles albimanus in el salvador ii. application of the nematode.	the mosquito breeding area of lake apastepeque, el salvador, was treated 11 times over a 7-week period with romanomermis culicivorax to control anopheles albimanus and an. p. pseudopunctipennis. parasitism averaged 58% but varied greatly from treatment to treatment and from site to site. however, three applications made during evening hours to avoid wind and wave action on the lake produced an average 86% parasitism. no significant differences in susceptibility to r. culicivorax were found betwe ...	1978	727331
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
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

efficiency of techniques for the mass release of sterile male anopheles albimanus wiedemann in el salvador.	during a 3-year program that required daily releases of large numbers of sterile male anopheles albimanus wiedemann mosquitoes in a coastal area of el salvador, we were able to compare methods of transport and release of adults and pupae. the disadvantages of the laboratory handling and packaging of adults were largely overcome when improved methods were devised for release of pupae. such releases saved time and laboratory space and overcame several logistical problems arising from evening relea ...	1980	7406117
