Abstract

Relative content of insecticidal protein in Bt rice pollen was much different after exposure to sunlight directly within different times.The content of insecticidal protein in Bt rice pollen decreased obviously at the beginning,and then tended to get higher along with the increase of treatment time.There was no significant effect of direct exposure to sunlight on the content of soluble protein in Bt rice pollen.Laboratory bioassay results showed the toxicity of Bt rice pollen exposed to sunlight directly within different times was similar against the first instars of silkworm,Bombyx mori,though LC50 value of the pollen increased with the treatment time extension.It suggested that there was no remarkable effect of exposure to sunlight directly on the content and activity of insecticidal protein in Bt rice pollen.
