Evaluation of AquatainTM monomolecular surface film against mosquito larvae of Culex pipiens in a full-grown rice field in Greece

The impact of the monomolecular surface fi lm AquatainTM against mosquito larvae was tested in a rice field in Central Greece. AquatainTM was poured in a 1.2 hectare rice paddy along the one side of the field. Laboratory reared mosquito larvae of Culex pipiens were introduced into cages placed in three different transects along the short side of the rice paddy. Larval mortality was counted 3, 6, 15 and 25 days after application. In the line located closer to the site of AquatainTM application, larval mortality ranged from 100% to 70%, 25 days after application. Mortality ranged from 88% to 25% in the middle transect and from 42%, to 10% in the more distant line. The results indicated that AquatainTM provides sufficient larval control in wide mosquito larval habitats
