Outline of Final Research Achievements

1)Ascovirus isolate found in Japan encoded plural parasitoid killer toxin (pkt) homologue were encoded in the genome.
2) Meteorus pulchricornis was a vector of Japanese isolate of ascovirus.
3) Progeny of M. pulchricornis was successfully emerged from the ascovirus infected host. It suggests that the hypothetical reason for ascovirus Japanese isolate encoding PKT is due to eliminate the competitor(s) of vectors’ progeny but not vectors’ progeny themselves.
