Attempted discrimination of Myzus persicae and Myzus nicotianae (Homoptera : Aphididae) by random amplified polymorphic DNA polymerase chain reaction technique
(1998)Random amplified polymorphic DNA (RAPD) analysis was applied to several clones of the Myzus persicae (Sulzer) group from Greece to assess genetic markers that could distinguish the tobacco feeding clones from those feeding ... -
Development, growth, feeding and reproduction of Ceratomegilla undecimnotata, Hippodamia variegata and Coccinella septempunctata fed on the tobacco aphid, Myzus persicae nicotianae
(2015)The demographic parameters and the larval aphid consumption of the predatory coccinellids Hippodamia variegata (Goeze) and Ceratomegilla undecimnotata (Schneider) were examined at five constant temperatures (17, 20, 23, ... -
Distribution of common genotypes of Myzus persicae (Hemiptera: Aphididae) in Greece, in relation to life cycle and host plant
(2007)Microsatellite genotyping was used to identify common clones in populations of the Myzus persicae group from various hosts and regions in mainland Greece and southern Italy and to compare their distribution and occurrence ... -
Effect of temperature and photoperiod on the life cycle in lineages of Myzus persicae nicotianae and Myzus persicae s. str. (Hemiptera : Aphididae)
(2006)Male production was examined in 70 Myzus persicae s.str and M. persicae nicotianae clonal lineages at 17 degrees C and 10L : 14D. Sixty nine were characterised by a partial loss of sexuality (androcyclic producing few ... -
Effect of temperature on development, growth and feeding of Coccinella septempunctata and Hippodamia convergens reared on the tobacco aphid, Myzus persicae nicotianae
(2005)Preimaginal development, mortality, aphid consumption rate, and size and weight upon reaching the adult stage of the aphidophagous coccinellids Hippodamia convergens Guerin-Meneville and Coccinella septempunctata L. collected ... -
Evolution of imidacloprid resistance in Myzus persicae in Greece and susceptibility data for spirotetramat
(2017)BACKGROUND: Myzus persicae s.l. is a major crop pest globally and has evolved resistance to a range of insecticide classes making it increasingly difficult to control in some areas. Here we compare bioassay monitoring data ... -
Feeding studies on gynoparae, males and apterous virginoparae of Myzus persicae on potato by electrical penetration graph
(2004)Feeding behaviour of parthenogenetic apterae, post-teneral gynoparae and males of a holocyclic parthenogenetic lineage of Myzus persicae (Sulzer) (Hem., Aphididae) was studied on potato plants, Solanum tuberosum L. ... -
Genetic variation in Myzus persicae populations associated with host-plant and life cycle category
(2001)Random amplified polymorphic DNA (RAPD) analysis was applied on 96 clones of Myzus persicae (Sulzer) (Homoptera: Aphididae) representing seven populations collected from different host-plants and regions of Greece. Ten ... -
Host selection by winged colonisers within the Myzus persicae group: A contribution towards understanding host specialisation
(2005)1. Myzus persicae sensu lato demonstrates considerable genetic variation in respect to adaptation to host plants. The subspecies M. persicae nicotianae shows a preference for tobacco, while M. persicae sensu stricto (s. ... -
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 ... -
Insecticide resistance status of Myzus persicae in Greece: Long-term surveys and new diagnostics for resistance mechanisms
(2016)BACKGROUND: Myzus persicae nicotianae is an important pest in Greece, controlled mainly by neonicotinoids. Monitoring of the aphid populations for resistance mechanisms is essential for effective control. RESULTS: Two new ... -
An interval timer controls the production of sexual morphs in Myzus persicae (Homoptera : Aphididae)
(2002)The interval timer mechanism was examined in two clones of Myzus persicae (Sulzer) originating from peach in Naousa, North Greece. Overwintering eggs were collected in April 1997 and after egg hatch the morphs of progeny ... -
Long-term studies on the evolution of resistance of Myzus persicae (Hemiptera: Aphididae) to insecticides in Greece
(2021)The aphid Myzus persicae s.l. (Hemiptera: Aphididae) is an important pest of many crops worldwide with a complex life cycle, intensely controlled by chemical pesticides, and has developed resistance to almost all used ... -
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 ... -
Performance of the tobacco aphid Myzus persicae (Hemiptera : Aphididae) on Oriental and Virginia tobacco varieties
(2003)1 The life parameters of one red and one green clone of Myzus persicae reared on 11 Oriental tobacco type varieties (KP7, K63, KZ10/z, MA13/b, BX2/a, N34/4, KP14/a, Kolindros, S79, TA21 and BX81) and on five Virginia ones ... -
