title: The mosquitoes of Sardinia: species records 35 years after the malaria eradication campaign.
abstract: 1. Thirty-five years ago malaria was eradicated from Sardinia by massive application of DDT directed against the mosquito vector species, Anopheles labranchiae, but the long-term effects on the mosquito fauna have not been investigated previously. 2. A 5-year mosquito survey (1980-85) involved in the inspection of 348 sites (plus 173 reinspections) and the processing of nearly 60,000 specimens. 3. Twenty-four species in six genera were identified from larval and adult collections. Species of the genera Culex (41%) and Aedes (22%) were more commonly encountered than Culiseta (18%) and Anopheles (17%) species. Orthopodomyia (1.6%) and Coquillettidia (0.6%) were far less frequent. 4. The species composition was similar to that described for the years of the eradication campaign, except for the genus Anopheles. Of the eight Anopheles species previously recorded, only four species were identified in collections of 1159 larvae from eighty-five positive sites. 5. Anopheles labranchiae was the most frequently collected species of its genus (49%), but was represented in only 12% of the total collections. Comparison with previous records indicated a progressive increase in sites positive for An.labranchiae over the past 35 years. 6. Anopheles hispaniola was not found, although it had apparently replaced An.labranchiae soon after the eradication campaign. An. labranchiae was common in the sites where the replacement phenomenon has been observed.
