Abstract

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
