A researcher checks trichogramma larvae (tiny black dots) parasitizing on tussor eggs in the pest natural enemy rearing center under Hunan Academy of Forestry in Changsha, capital of central China's Hunan Province, March 11, 2015. Without chemical pesticides, forestry scientists in the rearing center curb local forest pests by their natural enemies such as Dastarcus helophoroides, trichogramma and ladybird beetles. Those natural enemies could destroy pests of 200 species, according to a researcher of the center. snapress@snakorea.com
