“…2). Regardless of trap-to-trap spacing, all traps were placed in habitats that were shaded and contained vegetation (Lambrecht 1971). All sticky ovitraps were georeferenced with a hand-held global positioning system (GPS) device (MiTAC International Corp., San Dimas, CA).…”

Aedes albopictus (Skuse) is a container-breeding species with considerable public health importance. To date, Ae. albopictus oviposition behavior has been assessed in outdoor conditions, but only with laboratory-reared specimens. In outdoor large-cage and field studies, we used an attractive self-marking ovipositional device to assess Ae. albopictus skip oviposition behavior. In field studies, 37 wild Ae. albopictus that visited an attractive self-marking ovisite were subsequently captured at a sticky ovitrap within a 4-d period. Because the average Ae. albopictus gonotrophic period is 4.5-6 d, the wild-caught Ae. albopictus visited at least two oviposition sites within a single gonotrophic period. This provided field-based indirect evidence of skip oviposition. The mean distance traveled (MDT) during the 20-d evaluations ranged from 58 to 78 m. The maximum observed distance traveled was 149 m, which was the outer edge of our trapping ability. As populations of Ae. albopictus increased, the MDT during the 4-and 20-d post-marking period increased significantly. Additional observations of wild-marked and captured Aedes triseriatus (Say) are discussed.

“…In these islands, C. p. quinquefasciatus was relatively uncommon even as recently as 25 years ago, and was concentrated round Port Victoria, the capital (MATTINGLY and BROWN, 1955). Some 15 years later, LAMBRECHT (1971) found it was abundant throughout the Archipelago, where it had colonized not only its classical larval habitats but other less suitable types as well. Thus C. p. quinquefasciatus was successful in adapting to an environment where only a short time before it occupied only a relatively restricted habitat.…”

“…On the other hand, C. p. quinquefasciatus is widespread in the Ethiopian region, i.e. on the African continent south of the Sahara (HAMON el al., 1967) and in the neighbouring islands: Madagascar, the Mascarenes and the Comoro Archipelago (BRUNHES, 1975), the Seychelles and the Chagos Archipelago in the Indian Ocean (LAMBRECHT, 1971), Sao Tome and Fernando-Po in the Gulf of Guinea, and the Cape Verde islands in the Atlantic .…”

This paper is an attempt to synthesize information available on C. p. quinquefasciatus in Africa. The latter is presently found in most urban areas of the African continent and in rural settlements which show some trends towards urbanization. In East Africa, and the islands of the Indian Ocean, C. p. quinquefasciatus is one of the major natural vectors of Wuchereria bancrofti. In addition it can also transmit, under laboratory conditions, some other pathogenic agents.Preimaginal forms develop in different kinds of man-made breeding-places, especially those containing polluted water. The situation in each African region is reviewed in detail.Female behaviour during the different phases of the gonotrophic cycle is analysed, together with population dynamics.Control methods by synthetic insecticides are discussed in relation to resistance problems and the characteristics of the breeding sites. Other control methods based on the use of growth regulators, genetic manipulation, biological agents (parasites and predators) and environmental management have been investigated as well. Most of them cannot be easily applied or are not yet applicable for control operations.
