Contribution of Multiple Isolating Barriers to Reproductive Isolation Between a Pair of Phytophagous Ladybird Beetles
TLDR
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. Expand
Composition of aquatic invertebrates associated with macrophytes in Lake Tonle Sap, Cambodia
TLDR
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.

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)Expand
Comparison of genetic variation in growth performance on normal and novel host plants in a local population of a herbivorous ladybird beetle, Epilachna vigintioctomaculata
TLDR
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. Expand
Two Cryptic Species of the Phytophagous Ladybird Beetle Epilachna vigintioctopunctata (Coleoptera: Coccinellidae) Detected by Analyses of Mitochondrial DNA and Karyotypes, and Crossing Experiments
TLDR
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. Expand
Molecular Phylogeny of Twelve Asian Species of Epilachnine Ladybird Beetles (Coleoptera, Coccinellidae) with Notes on the Direction of Host Shifts
TLDR
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. Expand
Divergent host plant specialization as the critical driving force in speciation between populations of a phytophagous ladybird beetle
TLDR
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. Expand
Genetic basis for established and novel host plant use in a herbivorous ladybird beetle, Epilachna vigintioctomaculata
TLDR
Examining growth performance on both the established and a novel host in a herbivorous ladybird beetle, Epilachna vigintioctomaculata Motschulsky, suggests that host expansion may not be constrained genetically, at least at the initial stage of host range evolution. Expand
Genetic architecture for normal and novel host‐plant use in two local populations of the herbivorous ladybird beetle, Epilachna pustulosa
TLDR
The results suggest that the host‐range is not restricted by the antagonistic genetic associations among exploitation abilities on different plant species, but rather that selection of different host‐plants may improve the coordination between genes responsible for the use of different plants.
