| Popis: | This is the report on the biology of insect injurious to the confections in Aichi Prefecture by our observation. Injurious insects mostly appear between July and September through the year. We report herewith thirteen species of insect injurious to the confections, of which eight species were directly examined and determined of their specific names. Most important species were Plodia interpunctella Hubner and Oryzaeophilus surinamensis Linne.According to our observation, the packages of thin cellophane and alminium foil were invasive easily by the larva of P. interpunctella and its adult of more oviposited to the comparatively dark places.We determined the effectiveness of repellent medicine and had compared the different thirteen repellents to P. interpunctella, O. surinamensis and Tribolium castaneum Herbst. Most repellents were useful to P. interpunctella and O. surinamensis but heptyl acetate to O. surinamensis and camphene, n-heptyl alcohol, isoamyl acetate and di-n-butyl Succinate to P. interpunctella indicated the inducement. Acetophenone, camphene and indalone were useful to T. castaneum, but α-pinene, 2, 3, 4-tetrachlorobutane and heptyl acetate indicated the inducement and put the insect to death.Additionally, the larva of Cryptolestes turcicus (Grouvelle) is described and illustrated first in Japan. |
