“…The results correspond to the so called Danilevski's rule that the CPP becomes about 1 h 30 min longer per 5° of increased latitude (Danilevski 1965, Danilevski et al 1970. Divergence can be estimated in darwin units based on the range of annual expansion speeds (80 -130 km year -1 ) and the distance between the populations (Haldane 1949, Johnson 1967). Evolution in CPP has been rapid as indicated by darwin unit estimates (between Emmen and Padua, 12537 -20198 units).…”

“…Indeed, the common name, Colorado potato beetle, stems from the first American state where a major outbreak occurred (Casagrande 1987). Today L. decemlineata is the worldwide most important insect pest of potato found in an area covering 16 million km 2 which stretches from Mexico, through North America, to most of Europe and deep into Asia (Johnson 1967, Alyokhin 2009, EPPO 2006. The invasion has been rapid, since the first major outbreak happened as recently as around 150 years ago (Casagrande 1987, Alyokhin 2009).…”

High Stability of a Mitochondrial Genetic Marker mtCOII in Polish Colorado Potato Beetle Populations

et al. 2014

Colorado potato beetle (CPB) (Leptinotarsa decemlineata (Say in Journal of the Academy of Natural Sciences of Philadelphia 3: 298-331, 1824)) (Coleoptera: Chrysomelidae) is one of the most serious potato pests. It has been reported worldwide, from North America to Europe and Asia. In this study we analyzed the genetic diversity of a mitochondrial DNA marker -a second subunit of cytochrome oxidase (mtCOII) in Polish CPB populations to assess the possible changes of this gene sequence over time and over the country, influencing the intra-specific variability of CPB. During a three-year survey in Polish potato fields the beetles were collected from 20 evenly spaced locations of varying climatic and geographic conditions, and the nucleotide sequence of this marker was analyzed. Our research revealed that in spite of three years of sampling the mitochondrial haplotype in all individuals was fixed, and no single nucleotide change was found in any individual, indicating a high stability of this maternally inherited marker in L. decemlineata. This finding about the level of biodiversity is of importance for plant protection strategies.Resumen El escarabajo de la papa de Colorado (CPB) (Leptinotarsa decemlineata (Say in Journal of the Academy of Natural Sciences of Philadelphia 3: 298-331, 1824)) (Coleoptera: Chrysomelidae) es una de las plagas más serias en papa. Se ha reportado en todo el mundo, desde Norteamérica a Europa y Asia. En este estudio analizamos la diversidad genética de un marcador de ADN mitocondrial -una segunda subunidad de citocromo oxidasa (mtCOII) en poblaciones polacas de CPB para ver los posibles cambios en la secuencia de este gene en el tiempo y en el país, que estuvieran influenciando la variabilidad intraespecífica del CPB. Durante los tres años del estudio en los campos de papa polacos se colectaron los escarabajos de veinte localidades espaciadas uniformemente de condiciones climáticas y geográficas variables, analizando la secuencia de nucleótidos de este marcador. Nuestra investigación reveló que a pesar de los muestreos por tres años, el haplotipo mitocondrial era fijo en todos los individuos, y no se encontró un solo cambio de nucleótido en ningún individuo, indicando una gran estabilidad de este marcador heredado maternalmente en L. decemlineata.

“…Stabilisation of population densities at a lower level following an initial population outbreak has been reported of several colonizing species after they had spread into new areas (Johnson, 1967). A recent example in Lake Zürich in addition to D. polymorpha is the gastropod Potamopyrgus antipodarum, which reached high local population densities (Ribi and Arter, 1986) shortly after it was first noticed in the lake (Walter, 1980), and which has maintained stable populations at lower densities in recent years (Ribi, unpublished).…”

A population explosion of the zebra mussel Dreissena polymorpha in Lake Zürich in the early seventies was followed by a decline, most noticeably in the littoral zone (Burla and Lubini-Ferlin, 1976). To check for further density changes, zebra mussels were counted every winter from 1978 to 1988, and larval settlement was recorded every summer from 1976 to 1988. During this period, mussel densities ranged from 11 to 1500 ind. m -2 ; juvenile densities from 11 to 108 ind. cm -2 . Counts of newly settled juveniles and counts of established mussels were positively correlated between years. This suggests that the number of larvae in any given year depends on the size of the breeding population of mussels. Juvenile counts from different sites were more similar than mussel counts in any given year, indicating that within-lake dispersal of larvae is high. In both newly settled juveniles and established mussels, density variation occurred in what appeared to be two full cycles of 5 years. Mussel densities were positively correlated with total bird counts of three known predators of D. polymorpha, the Coot (Fulica atra), Tufted duck (Aythya fuligula), and Pochard (A. ferina). Higher mussel densities were observed near Zollikon and Goldbach than at other sampling sites. This may be a consequence of a steeper, stonier slope of the lake bed at these sites. Twenty-eight years after it was first recorded in Lake Zürich, D. polymorpha appears to be firmly established in the lake.
