Aktywność fosfatazy kwaśnej i zasadowej u Drosophila melanogaster poddanej długotrwałemu działaniu dichlorfosu

The effects of a long-term action of organophosphate compound - dichlorvos (DDVP) on the acid and alkaline phosphatase activities in Drosophila melanogaster was studied. DDVP is among the most widely used chemicals in agriculture in the world. Examined enzymes: alkaline phosphatase and acid phosphatase were extracted from several generations of DDVP-treated strains of Drosophila melanogaster. The increased activities of tested enzymes (alkaline and acid phosphatase) in fruit flay is positively correlated with the resistance to phosphorus insecticide - DDVP. It was found that the stimulating effects of DDVP on the activities of both enzymes was time- and dose-dependent. The most visible changes in the activities of tested enzymes (increased activities of acid and alkaline phosphatase) were found in the XV and XX generations of Drosophila melanogaster.
