| Popis: | Larvicides play a vital role in controlling mosquitoes in their breeding sites. The present study was carried out to establish the larvicidal and anti-ant activities of polyester amide based polyurethane coating from algae oil against mosquitos’ larvae and red ants responsible for diseases of public health importance. The polyester amide synthesized by N , N -bis (2-hydroxy ethyl) algae oil fatty amide and ethylene diamine tetra acetic acid through condensation polymerization. After that resin cured with MDI to obtained polyurethane coatings. Coating performance was tested. Larval mortality of mosquito’s larvae was observed at 12, 24 and 48 h of exposure to different weight of PU films. The efficacy of polyurethane coating films against mosquitos’ larvae (LC 50 and LC 90 ; 5.35 and 17.15 mg/mL) respectively were observed by probit analysis while the mortality of ants also observed at 2, 4, 6 and 12 h of exposure to PU coatings. Polyurethane coatings can be recommended effectively in mosquitos and ants controlling practices. The cytocompatibility study was also carried out and study shows good results. |
