Drosophila melanogaster commonly known as Fruit Fly has been used as a model organism in a great number of toxicity test due to its ease of manipulating and cultivating it. One such study on the toxicity of AgNPs on Drosophila melanogaster reported acute and chronic toxicity effect. By reporting acute toxicity, half of the flies tested failed to finish their development cycle when exposed to a concentration of 20 mg L -1 . The fertility of Drosophila was decreased significantly after long time exposure to 5 mg L -1 AgNPs. However, due to adaptation the fecundity of Drosophila was regenerated . In other study of the Larvae of Drosophila were exposed to a concentration of silver nanoparticles at 50 and 100 µg mL -1 , which resulted in DNA damage and apoptosis related toxicity . This is summarized in Table .
