| Research Abstract |
(1) Studies on sex pheromones and mating behaviors of 7 species of genus Ostrinia in Japan
Sex pheromone components of 6 species ; O.furnacalis, scapulalis, zaguliaevi, zealis, palustralis and latipennis were identified. Geographical variations in pheromone components of O.furnacalis and genetic variations in O.scapulais were shown
(2) Phylogenetic analyzes of genus Ostrinia in Japan by using mitochondrial COII gene
COII genes of 6 species were sequenced. Interspecific analyzes supported the relationship based on traditional morphology between group 2 (O.palustrallis and latipennis) and group 3 (O.furnacalis, orientalis, scapulalis, zagliaevi and zealis), but did not among species in group 3.Intraspecific analyzes showed variations of nearly 1% in each species except O.furnacalis having no variation.
(3) Re-examination of morphological comparison in Ostrinia
Five species in group 3, which were very difficult in morphological identification, were found to be distinguished from each other by morphology of middle-legs, abdominal scales and genitalia in male adults. Some specimens very closed to O.zagliaevi collected in southern islands of Japan were found to be a different species based on the morphology of male abdomen.
(4) Male pheromone of Conogethes punctiferalis
Tiglic acid was identified from male moths as attractive substance to male moths.
