Abstract:

The new type of autodissemination, the technique of sex pheromone plus virus dispenser, was proposed. To the dispenser, which releases sex pheromone and has lnsect virus on it, males are attracted and contaminted with the virus. When the males with the virus mate with females, the virus is transfered to them and then to their eggs. Afterwards the larvae from the eggs get disease and died. The experiments in wind tunnel showed that when the males of Clania variegata flied to the sex pheromone plus virus dispenser and attempted to mate with it, they were contaminated with the nuclear polyhedrosis virus of C. variegata(CVNPV). Males contaminated with CVNPV artificially were able to pass the virus to the larvae of the next generation by mating with females in the wind tunnel and it resulted in larvae mortality at certain level. Those results demonstrated feasibility of the technique of sex pheromone plus virus dispenser in its two important steps in vertical transmisson of the virus disease.
