Competitive interaction and niche differentiation among burying beetles (Silphidae, Nicrophorus) in northern Japan
Composition of aquatic invertebrates associated with macrophytes in Lake Tonle Sap, Cambodia
It is suggested that water movement can be an important factor determining the distribution and abundance of the sessile animals by controlling larval dispersions and might be associated with the hydrological characteristic of the lake, i.e., the lake opens to the large Mekong River with drastic seasonal changes in water level.
Contribution of Multiple Isolating Barriers to Reproductive Isolation Between a Pair of Phytophagous Ladybird Beetles
Host fidelity contributed most strongly to reproductive isolation by reducing interspecific hybridization through several important types of ecological isolation, including microspatial, habitat, and seasonal isolation.
CLASSIFICATION AND EVOLUTION OF THE PHYTOPHAGOUS LADYBIRDS BELONGING TO HENOSEPILACHNA VIGINTIOCTOMACULATA COMPLEX （COLEOPTERA, COCCINELLIDAE）

Title Classification and Evolution of the Phytophagous Ladybirds Belonging to Henosepilachna vigintioctomaculata Complex (Coleoptera, Coccinellidae) (With 165 Text-figures and 12 Tables) Author(s)…
Comparison of genetic variation in growth performance on normal and novel host plants in a local population of a herbivorous ladybird beetle, Epilachna vigintioctomaculata
The results are compatible with the view that natural selection, which improved the ability of the population to use a particular host plant, has reduced genetic variation within that population in the ability to use that host plant.

It is concluded that E. vigintioctopunctata, a notorious pest of solanaceous crops in Asia and Australia, is composed of at least two reproductively isolated biological species that probably occupy different geographic ranges.
Molecular Phylogeny of Twelve Asian Species of Epilachnine Ladybird Beetles (Coleoptera, Coccinellidae) with Notes on the Direction of Host Shifts
The nucleotide sequences of a part of the mitochondrial cytochrome c oxidase I gene (1,000 bp) for twelve species of Asian phytophagous ladybird beetles belonging to the genus Epilachna are determined and molecular phylogenetic trees are constructed using two “Epilachnines” species as outgroups.
A PRELIMINARY STUDY ON THE FAUNAL MAKE-UP AND SPATIOTEMPORAL DISTRIBUTION OF CARRION BEETLES (COLEOPTERA : SILPHIDAE) ON THE ISHIKARI COAST, NORTHERN JAPAN
Female internal reproductive organs, modes of sperm transfer, and phylogeny of Asian Epilachninae (Coleoptera: Coccinellidae).
A total of 22 Indonesian and Japanese species of epilachnine ladybird beetles were divided into the following three groups on the basis of the conditions of bursa copulatrix and spermatheca, and…
Divergent host plant specialization as the critical driving force in speciation between populations of a phytophagous ladybird beetle
This work tested isolating barriers between host races of a phytophagous ladybird beetle, Henosepilachna diekei, and found significant genetic divergence between the host races, and extremely divergent host preference and host performance.
