Direct behavioral evidence for hydrocarbons as nestmate recognition cues in Formica japonica (Hymenoptera: Formicidae)
There is direct evidence that cuticular hydrocarbons are responsible for nestmate recognition in Formica japonica distributing in Southern Honshu in Japan and both n-alkanes and (Z)-9-alkenes are necessary to discriminate nestmates from foreign conspecifics.
Sexual dimorphism in body dimensions and antennal sensilla in the white grub beetle, Dasylepida ishigakiensis (Coleoptera: Scarabaeidae)
The white grub beetle, Dasylepida ishigakiensis shows sex dimorphism in body dimensions and abundance of antennal sensilla and among individuals that were collected as third stadium larvae on Miyako Island, Okinawa, Japan and reared in the laboratory, three emerged as adults with asymmetrical antennae.
Mating sequence and evidence for synergistic component in female contact sex pheromone of the white-spotted longicorn beetle, Anoplophora malasiaca (Thomson) (Coleoptera: Cerambycidae).

Mating Disruption for Control of Melanotus okinawensis (Coleoptera: Elateridae) with Synthetic Sex Pheromone
Results indicated that the mating disruption effectively reduced an isolated population of Melanotus okinawensis Ohira on Minami-Daito Island.
Control of the sugarcane click beetle Melanotus okinawensis Ohira (Coleoptera: Elateridae) by mass trapping using synthetic sex pheromone on Ikei Island, Okinawa, Japan
The results indicated that mass trapping with a high density of sex pheromone traps may effectively reduce an isolated population of M. okinawensis.
Reinvestigation of sex pheromone components and attractiveness of synthetic sex pheromone of the pink borer, Sesamia inferens Walker (Lepidoptera: Noctuidae) in Okinawa
Two EAG-active compounds were found in the solvent extract of abdominal tips ofirgin females of the pink borer Sesamia inferens, and the attractiveness of this blend is comparable with that of virgin females.

Intraspecific Variation of Cuticular Hydrocarbon Composition in Formica japonica Motschoulsky (Hymenoptera: Formicidae)
The occurrence of four distinct types of CHC composition suggests that the colonies that produce them are separate species, and is supported by a principal component analysis.
