Correlation Between Cyclin B1 Immunostaining in Cervical Biopsies and HPV Detection by PCR
(2009)In recent years, experimental data on the roles of viruses and cyclin B1 in G2/M arrest has accumulated. The aim of our study Was to immunohistochemically examine a series of cervical squamous intraepithelial lesions for ... -
Diapause termination of Rhagoletis cerasi pupae is regulated by local adaptation and phenotypic plasticity: escape in time through bet-hedging strategies
(2014)Persistence and thriving of univoltine, herbivore insect species of the temperate zone rely on obligate diapause response that ensures winter survival and synchronization with host phenology. We used a stenophagous fruit ... -
Genetic diversity and insecticide resistance during the growing season in the green peach aphid (Hemiptera: Aphididae) on primary and secondary hosts: a farm-scale study in Central Chile
(2014)The seasonal dynamics of neutral genetic diversity and the insecticide resistance mechanisms of insect pests at the farm scale are still poorly documented. Here this was addressed in the green peach aphid Myzus persicae ... -
Host-related morphological variation within Myzus persicae group (Homoptera : Aphididae) from Japan
(2007)There have been independent long-term studies of tobacco-adapted populations of Myzus persicae in Japan and Greece, but until now no direct comparisons have been made between them. In Japan, as in Greece, tobacco aphids ... -
Insecticide resistance status of Myzus persicae (Hemiptera : Aphididae) populations from peach and tobacco in mainland Greece
(2007)The susceptibility of 88 and 38 field samples of Myzus persicae (Sulzer) to imidacloprid and deltamethrin respectively was examined using the FAO dip test bioassay. The field samples were collected from tobacco and peach ... -
Micro-evolutionary change in relation to insecticide resistance in the peach-potato aphid, Myzus persicae
(2010)2. Asexual organisms rely on mutation whereas sexual organisms combine mutation with recombination. 3. Few organisms provide examples of species that are both sexual and asexual, but aphids do. 4. To examine evolution on ... -
Plankton Microorganisms Coinciding with Two Consecutive Mass Fish Kills in a Newly Reconstructed Lake
(2012)Lake Karla, Greece, was dried up in 1962 and its refilling started in 2009. We examined the Cyanobacteria and unicellular eukaryotes found during two fish kill incidents, in March and April 2010, in order to detect possible ... -
Predominance of parthenogenetic reproduction in Aphis gossypii populations on summer crops and weeds in Greece
(2009)The photoperiodic response of 56 parthenogenetic lineages of Aphis gossypii Glover was examined by rearing the aphids for three generations under short day conditions (SD, L 10:13 14) and 17 degrees C. The lineages were ... -
Prolonged pupal dormancy is associated with significant fitness cost for adults of Rhagoletis cerasi (Diptera: Tephritidae)
(2012)In temperate areas, dormancy (diapause and/or quiescence) enables herbivorous insect species to persist and thrive by synchronizing growth and reproduction with the seasonal phenology of their host plants. Within-population ... -
Recent changes in the distribution of carboxylesterase genes and associated chromosomal rearrangements in Greek populations of the tobacco aphid Myzus persicae nicotianae
(2014)We present data on the frequency of amplified E4 and FE4 carboxylesterase genes in Myzus persicae s.l. clones collected during the years 2002-2007 and 2012 in Greece. Most clones were of the tobacco aphid, Myzus persicae ...
