Abstract:
Cadmium is one of the important heavy metal pollutants with strong toxicity and wide distribution. It poses a threat to human health and invertebrates,especially to insects. It has been demonstrated that cadmium can infiltrate into insects through respiration ,food intake and so on. It can affect their development,and even induce apoptosis via oxidative damage. Insects can gradually develop defense mechanisms against cadmium with the help of metallothionein,antioxidant enzymes, excretion and heat shock protein. Toxicity effect varies among different species. This paper reviewsed the effect of cadmium on development,cell apoptosis mechanism and defense mechanism in insects.
