Aedes aegypti infestation-associated containers in Lisa municipality

[摘要] INTRODUCTION: Aedes aegypti has great ecological plasticity that allows it to use a range of containers to lay its eggs.OBJECTIVE: to identify the main containers associated with indoor and outdoor infestation by this species.METHODS: one municipality of the City of Havana (Lisa) was completely sampled during November 2007 and January 2008; all water containers were checked and also breeding reservoirs were classified into 10 groups.RESULTS: a total number of 773 containers were found positive to this vector; 654 of them (84.6 %) outdoors and 119 (15.4 %) indoors. Forty eight different containers were detected outdoors and 31 indoors. The main positive groups found inside and outside the house were water containers amounting to 45 (37.81 %) and 314 (48.01 %) respectively, and non-useful artificial containers covering 27 (22.68 %) and 209 (31.95 %), respectively. Tanks located on the ground indoors and outdoors represented more than half of the positive containers, that is, 23 (51.11 %) and 180 (57.32 %) whereas in the group of non-useful artificial containers located outdoors, cans showed the highest positivity rate with 57 (27.28 %), followed by casseroles and a group of various reservoirs which accounted for the highest positivity indoors, that is, 12 (44.44 %).CONCLUSIONS: the containers associated with the highest rate of infestation by Ae. aegypti indoors and outdoors were water tanks and the group of non-useful artificial containers, taking also into account vases, water glasses for religious ritual offerings, flower pots and toilets inside the house, and troughs, tyres and sewages outside.
