Geographic Variation in Sex Pheromone of Asian Corn Borer, Ostrinia furnacalis, in Japan
TLDR
Geographic variation in the sex pheromone of the Asian corn borer, Ostrinia furnacalis (Guenée), was surveyed in populations sampled at four locations in Japan and confirmed that there were two distinct phenotypes regarding the E ratio.
Sex pheromone of the butterbur borer, Ostrinia zaguliaevi
TLDR
It was concluded that the sex pheromone blend of O. zaguliaevi is composed of Z9‐, E11‐ and Z11‐14:OAc at a ratio of 45:5:50, and removal of any single compound from the ternary blend significantly diminished the pheromonal activity.
Predicted voltinism of the camellia spiny whitefly, Aleurocanthus camelliae (Hemiptera: Aleyrodidae), in major Japanese tea-producing districts based on life history parameters
TLDR
Results suggested A. camelliae voltinism of two to three generations per year in Kanto, Tokai, and Kinki districts and three to five generations peryear in the Shikoku and Kyushu districts, Japan.
Development and Fecundity of Orius sauteri (POPPIUS) (Hemiptera: Anthocoridae) Reared on Aphis gossypii GLOVER and Corn Pollen.
TLDR
Aphis gossypii is a sufficient diet for rearing this species, compared to Thrips palmi, a suitable diet reported by NAGAI (1993), suggesting that corn pollen alone is not sufficient for reared O. sauteri.
Sex pheromone of the rice leaffolder moth, Cnaphalocrocis medinalis (Lepidoptera: Crambidae): Synthetic Indian and Philippine blends are not attractive to male C. medinalis, but are attractive to C.
TLDR
Field bioassays with 3 different types of synthetic pheromone blends (Japanese, Indian and Philippine blends) based on geographic variation in the sex phersomones in Cnaphalocrocis medinalis were performed in 1998 and 1999 in the South-Western Islands of Japan, finding that neither the Japanese nor the Philippine blend showed attractiveness, as in the Japan mainland.
Relationships Between Nest-Dwelling Lepidoptera and Their Owl Hosts
TLDR
Tineids are presumed to decompose keratin found in owl nests and help maintain the cleanliness of the nest chamber, and such relationships between tineids and owls may be mutualistic.
