Taiwan is at the northeastern limits of the Asian center of diversity for fruit flies in the tribe Dacini, and the country has several endemic species.
We found no genetic structure between B. dorsalis and B. carambolae and our findings suggest recent and most likely ongoing, genetic exchange between these two species in the wild. Hyper-diverse mitochondrial genetic diversity in the native range suggests large population sizes and relatively high mutation rates.
The increase in abundance of A. treitschkiella in the Netherlands since the early 1990s and in Great Britain in recent years must be regarded as part of a recent expansion into north-western Europe, whereas the native A. petryi is hardly expanding and less abundant
The Solanum fruit fly, Bactrocera latifrons (Hendel) is one of four invasive true fruit flies in Hawaii and primarily attacks peppers, tomatoes and other Solanaceae. The University of Hawaii Insect Museum collections hold a greater variation of forms than was described in the literature, which has likely led to some confusion regarding identification
We present here a molecular phylogeny based on eight gene fragments from 355 species, representing 20 out of 22 extant Nepticulidae genera. Using two fossil calibration points, we performed molecular dating to place the origin of the family in the Early Cretaceous, before the main Angiosperm diversification.
We provide a historical overview of taxonomic research on Nepticuloidea and a brief ‘state of the art’. A DNA barcode dataset with 3205 barcodes is made public at the same time, providing DNA barcodes of ca. 779 species, of which 2563 are identified as belonging to 444 validly published species.
The research I performed focused on comparing their species-level phylogenetic diversification patterns, based on a dataset that included the majority of their global diversity, to understand common factors that have driven their evolution.
These observations suggest that species-level non-monophyly in COI gene trees is less common than previously supposed, with many cases reflecting misidentifications, the subjectivity of species delimitation or other operational factors
Larvae of Phyllocnistis unipunctella (Stephens) mining the upperside and underside of leaves of Populus spp. were compared in terms of gross morphology and the COI DNA barcoding section of mitochondrial DNA.
After finding distinct clades in a molecular phylogeny for Nepticulidae that could not be placed in any known genera and discovering clear apomorphic characters that define these clades, as well as a number of Neotropical species that could be placed in known genera but were undescribed, three new genera and nine new species are here described from the Neotropics
