Direct behavioral evidence for hydrocarbons as nestmate recognition cues in Formica japonica (Hymenoptera: Formicidae)
TLDR
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. Expand
Sexual dimorphism in body dimensions and antennal sensilla in the white grub beetle, Dasylepida ishigakiensis (Coleoptera: Scarabaeidae)
TLDR
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 Disruption for Control of Melanotus okinawensis (Coleoptera: Elateridae) with Synthetic Sex Pheromone
TLDR
Results indicated that the mating disruption effectively reduced an isolated population of Melanotus okinawensis Ohira on Minami-Daito Island. Expand
Control of the sugarcane click beetle Melanotus okinawensis Ohira (Coleoptera: Elateridae) by mass trapping using synthetic sex pheromone on Ikei Island, Okinawa, Japan
TLDR
The results indicated that mass trapping with a high density of sex pheromone traps may effectively reduce an isolated population of M. okinawensis. Expand
Reinvestigation of sex pheromone components and attractiveness of synthetic sex pheromone of the pink borer, Sesamia inferens Walker (Lepidoptera: Noctuidae) in Okinawa
TLDR
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. Expand
Intraspecific Variation of Cuticular Hydrocarbon Composition in Formica japonica Motschoulsky (Hymenoptera: Formicidae)
TLDR
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. Expand
Presence of larval and adult diapauses in a subtropical scarab beetle: graded thermal response for synchronized sexual maturation and reproduction
TLDR
Evidence is presented indicating that this beetle has two diapauses that appear to synchronize this long life cycle with the seasons, and adults of this beetle emerge from pupae late in the autumn and remain in the soil for 2 months, effectively serving to synchronizing the time of sexual maturation with the coldest month of the year.
