Graphene nanoparticles are one of the most attractive nanomaterials for commercialization applications. They have been widely used for antimicrobial, electronic and biomedical products. In this review, The exposure time to light plays an important role in mortality percentage, the percentage mortality increase when the exposure time increase and there an inverse relationship between concentration with the exposure time. Photoactive compound magnesium chlorophyllin had more significant effect on adult Bactrocera zonata after exposure to sunlight than magnesium chlorophyllin with graphene nanoparticles so that there was no benfit to use the mixture of magnesium chlorophyllin with graphene nanoparticles, magnesium chlorophyllin was more effeciant than Copper chlorophyllin with graphene nanoparticles or Copper chlorophyllin. Level of acid phosphatases in the homogenate of Bactrocera zonata, After exposure to sunlight for two hours after treated by compound Copper chlorophyllin or Magnesium chlorophyllin, results showed high increase (52.44%, 40.71%). After treated by compound Copper chlorophyllin with graphene nanoparticle or Magnesium chlorophyllin with graphene nanoparticle, the changes in alkaline phosphatases after treated by compound Copper chlorophyllin show limited rduction (-16.28%), on the other hand Magnesium chlorophyllin showed high incrase (77.14%) relative to control. Key wards: Bactrocera zonata, photoinsecticide, photosensitizer, chlorophyllin, illumination with sunlight, graphene nanoparticles, exposed, acid phosphatase (AcP), alkaline phosphatase (AlP).
