Host specialization by Cotesia wasps (Hymenoptera: Braconidae) parasitizing species-rich Melitaeini (Lepidoptera: Nymphalidae) communities in north-eastern Spain

In order to investigate parasitoids of the genus Cotesia (Hymenoptera: Braconidae), larvae of a speciose group of butterflies, the tribe Melitaeini (Lepidoptera: Nymphalidae), were collected from several sites in Catalonia, northern Spain, a region that harbours ten out of the 20 European species of Melitaeini. New information on the natural history of the butterflies is presented, and the structure of their communities and patterns of larval parasitism are described. On the basis of mtDNA sequence data (COI gene), microsatellite data (ten loci) and behavioural experiments, we recognize seven biologically distinct species of Cotesia parasitizing the Melitaeini communities within this relatively small geographical area. In particular, the notional species C. melitaearum and C. acuminata each represents a series of cryptic species with narrow host associations. The possibility of direct competition among the parasitoids and/or indirect interactions between butterflies mediated by Cotesia parasitoids is explored.  © 2005 The Linnean Society of London, Biological Journal of the Linnean Society , 2005, 86 , 45–65.

Non-destructive direct polymerase chain reaction (direct PCR) greatly facilitates molecular identification of spider mites (Acari: Tetranychidae)

Spider mites (Acari: Tetranychidae) include serious agricultural pests and some species have spread globally as invasive species.. For this reason, rapid and simple identification of spider mite species is necessary for agricultural field and plant quarantine inspection. DNA sequence-based molecular techniques can rapidly identify spider mites. However, extracting DNA from minute invertebrates is difficult, expensive and time consuming. Here, we describe a polymerase chain reaction (PCR) technique in which the whole body of a spider mite adult is non-destructively soaked in PCR solution. The mite is then removed intact and can be used as a voucher specimen, leaving the PCR solution as the template and avoiding the need for a DNA extraction kit. For this study, we used six common spider mite species from four genera [Tetranychus urticae Koch (red form), Tetranychus kanzawai Kishida, Tetranychus parakanzawai Ehara, Oligonychus gotohi Ehara, Eotetranychus smithi Pritchard & Baker and Panonychus citri (McGregor)]. A portion of the mitochondrial cytochrome c oxidase subunit I (COI) gene was amplified with a universal primer pair from all individuals examined and sequenced. This method shortened the time for molecular identification from 9 to 5 h and eliminated the cost of commercial kits for DNA extraction [ca. 600 yen (~5.3 USD) per sample].

Cross‐species amplification of zebrafish and central stoneroller microsatellite loci in six other cyprinids

One hundred and twenty Danio rerio and Campostoma anomalum microsatellite loci were tested for amplification in the cyprinids Phoxinus phoxinus, Scardinius erythrophthalmus, Rutilus rutilus, Abramis brama, Carassius carassius and Gobio gobio .

Molecular approach in spider mites (Acari: Tetranychidae): Preliminary data on ribosomal DNA sequences

DNA sequence data were used to examine phylogenetic relationships between six species of economically important Tetranychidae mites:Eotetranychus carpini (Oudemans),E. pruni (Reck),Tetranychus pacificus McGregor,T. mcdanieli McGregor,T. turkestani Ugarov & Nikolski andT. urticae Koch. With primers directed toward conserved elements flanking the target region, the Polymerase Chain Reaction was used to amplify the ITS2 spacer of the ribosomal DNA molecule. The nucleotide sequence of a 300-bp fragment of the ITS2 was determined by direct sequencing and nucleotide divergence used for intra-generic comparison in mites. The resulting phylogenetic tree expressing interspecific relationships in genusTetranychus agrees with morphological data. The study demonstrates the usefulness of the approach in the assessment of the systematics and evolution of the group.

Molecular variation and fingerprinting of Leucadendron cultivars (Proteaceae) by ISSR markers

BACKGROUND AND AIMS: There are more than 80 species of Leucadendron and most are used as cut flowers. Currently, more than 100 cultivars are used by industry and many of them are interspecific hybrids. The origin of most cultivars is unclear and their genetic diversity and relationships have not been studied. This investigation was carried out to evaluate the genetic variation and relationships among 30 Leucadendron cultivars. METHODS: ISSR markers were applied to determine the genetic variation and to discriminate Leucadendron cultivars. Sixty-four ISSR primers were screened and 25 primers were selected for their ability to produce clear and reproducible patterns of multiple bands. KEY RESULTS: A total of 584 bands of 305-2400 bp were amplified, of which 97 % were polymorphic. A dendrogram generated using the Unweighted Pair Group Method with Arithmetic Average based on a distance measure of total character difference showed that the Leucadendron cultivars clustered into two main groups. Twenty-four of the 30 cultivars can be unequivocally differentiated, but identical profiles were observed for three cultivar pairs, 'Katie's Blush' and 'Silvan Red', 'Highlights' and 'Maui Sunset', and 'Yellow Crest' and 'Yellow Devil'. CONCLUSIONS: ISSR profiling is a powerful method for the identification and molecular classification of Leucadendron cultivars. A fingerprinting key was generated based on the banding patterns produced using two ISSR primers (UBC856 and UBC857). In addition cultivar-specific ISSR bands were obtained for 17 of the 30 Leucadendron cultivars tested.

Phylogenetic and taxonomic relationships of northern Far Eastern phoxinin minnows, Phoxinus and Rhynchocypris (Pisces, Cyprinidae), as inferred from allozyme and mitochondrial 16S rRNA sequence analyses

Analyses of allozyme (18 loci) and partial mitochondrial DNA (mtDNA) sequences (1295 bp, 16S rRNA) support the classification of phoxinin minnows from the northern Far East into 2 genera of 8 species: Phoxinus phoxinus, Rhynchocypris oxycephalus, R. perenurus, R. czekanowskii, R. kumgangensis, R. semotilus, R. lagowskii and R. sp. (bergi ?). Although R. lagowskii from Japan and the Amur basin and R. sp. from Vladivostok region to Korea have been classified into a single species by many authors as R. lagowskii, they form separate clusters in both analyses, suggesting different specific status. Some R. oxycephalus and R. perenurus had the mtDNA haplotypes of R. lagowskii and R. czekanowskii, respectively, which probably indicates that local introgression of mtDNA occurred through inter-specific hybridization. Rhynchocypris forms a monophyletic cluster with dace genera Tribolodon and Pseudaspius, not with Phoxinus. Eurasian and American Phoxinus are suggested to be paraphyletic.

Host plant-mediated interactions between Tetranychus urticae and Eotetranychus carpini borealis (Acari: Tetranychidae)

Competitive interactions between Tetranychus urticae and Eotetranychus carpini borealis were investigated under laboratory and greenhouse conditions. When placed first to colonize red raspberry leaves, T. urticae caused extinction of E. carpini borealis populations. E. carpini borealis had detrimental effects on T. urticae but did not cause T. urticae population extinction. The area used by E. carpini borealis for egg deposition decreased with an increase in the number of T. urticae eggs. Red raspberry showed an induced response to T. urticae and E. carpini borealis feeding after two weeks of infestation. Population growth of each species was reduced on plants that were previously infested by conspecifics but inducible response by one species had no effects on the other species.
