TL;DR: A method for identifying the members of the endemic genus Wiseana Viette from New Zealand by generating molecular markers generated via amplification of the cytochrome oxidase subunit I and II of the mitochondrial DNA by the polymerase chain reaction (PCR).
Abstract: A method for identifying the members of the endemic genus Wiseana Viette from New Zealand is described. Seven species have been described in the genus: W. cervinata (Walker), W. copularis (Meyrick), W. fuliginea (Butler), W. jocosa (Meyrick), W. mimica (Philpott), W. signata (Walker) and W. umbraculata (Guenee). No morphological characters have been identified to distinguish between the larvae of each species and adult females exhibit high levels of intra and interspecific morphological variation making identification difficult or impossible. Adult males can be distinguished by a combination of scale, antennal and genital characters, but this requires considerable taxonomic experience. Molecular markers were generated via amplification of the cytochrome oxidase subunit I and II (COI and II) of the mitochondrial DNA by the polymerase chain reaction (PCR). Amplified DNA was digested with restriction enzymes to give characteristic fragment patterns. Fourteen restriction enzymes were surveyed and a combination of four of these distinguish all Wiseana taxa except W. fuliginea and W. mimica.
TL;DR: Three viruses, Wiseana nuclear polyherosis (WNPV), Wiseana entomopox (WEpox), and Wiseana granulosis virus, have been found to infect this insect and have been shown to be effective in controlling this pest to subeconomic levels.
TL;DR: The phylogeny of the New Zealand hepialid moths was estimated from a 527-bp nucleotide sequence from the mitochondrial DNA cytochrome oxidase subunit I and II gene regions and suggested that the genus Wiseana may have diverged 1-1.5 mya.
TL;DR: In young pastures virus mortality was shown to have a density-dependent relationship in which infected larvae ingeneration n could be related to the rate of virus infection in generation n + 1, which suggested that larvae were being infected at an early stage of their life cycle but that the virus could not be detected.
