| natural transovarial transmission of dengue 4 virus in aedes aegypti in trinidad. | the isolation of dengue 4 virus from adult aedes aegypti, reared from eggs collected in nature, is reported for the first time. from the locality where the isolate was made, 25 pools consisting of 1,848 ae. aegypti reared from eggs were processed. in this study, 10 different localities were sampled and a total of 10,957 ae. aegypti adults, collected as eggs or larvae in nature, were processed for virus isolation. from a total of 158 mosquito pools tested, one recovery of dengue 4 virus was made. ... | 1984 | 6542323 |
| transmission thresholds for dengue in terms of aedes aegypti pupae per person with discussion of their utility in source reduction efforts. | the expense and ineffectiveness of drift-based insecticide aerosols to control dengue epidemics has led to suppression strategies based on eliminating larval breeding sites. with the notable but short-lived exceptions of cuba and singapore, these source reduction efforts have met with little documented success; failure has chiefly been attributed to inadequate participation of the communities involved. the present work attempts to estimate transmission thresholds for dengue based on an easily-de ... | 2000 | 10761719 |
| surveillance for the dengue vector aedes aegypti in tobago, west indies. | an island-wide house survey was conducted in january 2002 to determine the geographic distribution, container profile, and population density of the aedes aegypti in tobago, west indies. the results showed the ae. aegypti infestation levels were significantly different (p > 0.01) among the 4 districts, with greater infestation levels (p > 0.01) observed in the northern and windward districts than in the central and leeward districts. from the 50 towns in tobago, houses were found positive in del ... | 2003 | 14524540 |
