| Abstract |
The field dispersal ability of cotton bollworm, Helicoverpa armigera (Hübner) irradiated with 300Gy of γ-rays was studied. The results showed that about 97% of cotton bollworm was dispersed in 720m. The 615 m was the farthest of average dispersal distance. The dispersal density of cotton bollworm was correlated with the reciprocal of dispersal distance, as the model: N= - 0183 + 1647134 / x. The dispersal of cotton bollworm had taxis to the green and fresh host |
