“…Nevertheless, misidentifications still occur (e.g., Hoelmer & Pickett 2003; Wanntorp 2004). Moreover, the status of some species of ladybirds remains controversial, as is the case within the genus Adalia (L.) (Palenko et al. 2004) or Coccinella L. (Iablokoff‐Khnzorian 1982).…”

2010). Coccinella septempunctata (Coleoptera, Coccinellidae): a species complex? -Zoologica Scripta, 39, 591-602. Coccinella septempunctata L., the seven spot ladybird is widely distributed across the Paleartic region. Based on a few morphological characteristics and geographical origin, some populations are recognized as distinct species, e.g., the North African Coccinella algerica Kovář and Japanese Coccinella brucki Mulsant later considered to be a subspecies -C. septempunctata brucki. The objective of this study is to discuss the taxonomic status of the seven spot ladybird, in particular whether it is a complex of species or the same species throughout the Paleartic region. The relationship between populations was clarified by using a combination of molecular and limited morphometric data and assessing potential reproductive barriers by means of cross breeding. Although there is considerable variation in the size of the spots on the elytra, the results of this study confirm that all studied populations belong to the same species.

“…Numerous studies have used the mitochondrial gene cytochrome oxidase I (COI) and the internal transcribed spacer (ITS) regions of ribosomal DNA (rDNA) to identify genetic relationships between species. Studies at within‐species level using COI and ITS regions are more limited: Genetic variation in COI and ITS regions have been used to simply characterize intraspecific variation (Palenko et al., 2004), explain the population changes due to geographic isolation (Leebens‐Mack & Pellmyr, 2004), document hydrographic separation of subterranean and surface habitats (Verovnik et al., 2004), and classify individuals into strains (Gomez & Gonzalez, 2004), subspecific clades (Shufran, 2003), or haplotypes (Tuda et al., 2004).…”

Genetic differentiation between eastern populations and recent introductions of potato psyllid (Bactericera cockerelli) into western North America

Although tomato psyllid, Bactericera cockerelli (Sulc) (Homoptera, Psyllidae), annually causes significant losses in potato and tomato crops in eastern Mexico and the central United States, infestations in western North America have been historically rare. However, substantial populations appeared in 2001 in western North America and caused losses in tomato production exceeding 80%; losses in 2004 reached 50%. To determine if these new outbreaks were the result of a simple range expansion or the evolution of a new B. cockerelli biotype, inter simple sequence repeat (ISSR) markers, as well as mitochondrial gene cytochrome oxidase I (COI), internal transcribed spacer 2 (ITS2), and wsp sequence data were used to characterize populations of the psyllid. Western populations from Baja, Mexico, Orange County, and Ventura County were compared with populations from central USA (Colorado and Nebraska) and eastern Mexico (Coahuila). Based on ISSR markers, the psyllid populations clustered into two groups, with one group including populations from western North America and the other group including populations from central USA and eastern Mexico. For COI comparisons, there was one base‐pair difference found in the 544 bp‐long COI fragments, but the populations again segregated along the same geographic lines. Two strains of Wolbachia were identified, the maximal differences between wsp clones from all populations was 5 bp for strain Bac1 and 23 bp for strain Bac2 out of a 555‐bp fragment. The ISSR data, therefore, were consistent in indicating the development of a new psyllid biotype that has adapted to western North America rather than a simple range expansion, but the other genetic data sets were less conclusive.

“…The Palaearctic 10-spot ladybird, Adalia decempunctata, is the sibling species of the well-studied generalist Adalia bipunctata (Lusis, 1973;Iablokoff-Khnzorian, 1982;Palenko et al, 2004) and the two species will even produce hybrid offspring in the laboratory . However, A. decempunctata is more specialised: whereas A. bipunctata occurs in the herbaceous layer, including crops, as well as shrubs and deciduous trees, A. decempunctata is largely restricted to the latter (Hon k 1985;Hon k & Hodek, 1996;Sloggett & Majerus, 2000).…”

Are we studying too few taxa? Insights from aphidophagous ladybird beetles (Coleoptera: Coccinellidae)

Abstract. Many areas of biology employ standard model organisms on which a majority of research effort is concentrated. However, there is invariably a danger associated with the use of too few or atypical models for studies of particular taxonomic groups, guilds or biological phenomena. Using aphidophagous ladybirds, I show that in this group, in the last ten years, 69% of research has been concentrated on just five species, all generalist ecotypes. Much research is now concentrated on invasive species, originally biocontrol agents, and over half the aphidophagous ladybird work on intraguild interactions is centred on two of the five predominant species, Coccinella septempunctata and Harmonia axyridis. Using examples from differing areas of research, I show that studies of more unusual, non-commercial specialists can enhance our understanding of the commonly studied groups. I suggest further areas where a similar approach may lead to equally illuminating results.
