Application of random amplified polymorphic DNA (RAPD) markers to evaluate intraspecific genetic variation in red mullet (Mullus barbatus)
(1998)The random amplified polymorphic DNA (RAPD) technique was used to evaluate genetic affinities among eight red mullet (Mullus barbatus L., 1758) samples from the Mediterranean Sea. Twenty-nine random primers were used. ... -
Co-existence of different host-adapted forms of the Myzus persicae group (Hemiptera : Aphididae) in southern Italy
(2003)Multivariate morphometric analysis (method of canonical variates) was used to compare 38 parthenogenetic lineages and three field collections of aphids of the Myzus persicae (Sulzer) group sampled on peach and tobacco in ... -
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, ... -
Discrimination of the closely related biocontrol agents Macrolophus melanotoma (Hemiptera : Miridae) and M-pygmaeus using mitochondrial DNA analysis
(2003)The separation of the closely related predatory species Macrolophus melanotoma Costa (= M. caliginosus Wagner) and Macrolophus pygmaeus (Rambur) based exclusively on the different colour pattern of the first antennal segment ... -
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 ... -
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 ... -
Life cycle variation of Myzus persicae (Hemiptera : Aphididae) in Greece
(2002)During the years 1995-1999 the life cycle category of 2797 clones of Myzus persicae (Sulzer) was examined. The clones originated from primary and secondary hosts from different localities of North and Central Greece and ... -
Morphological discrimination of Aphis gossypii (Hemiptera : Aphididae) populations feeding on Compositae
(2006)Aphis gossypii Glover is a polyphagous aphid pest with a worldwide distribution. However, there is evidence that on a global scale the name A. gossypii is being applied to a number of forms with different life cycles and/or ... -
Performance of cotton aphid Aphis gossypii (Hemiptera : Aphididae) lineages on cotton varieties
(2006)The performance of three clonal lineages of Aphis gossypii Glover originating from central Greece was studied on six commercial cotton cultivars that differ with respect to leaf pubescence traits (Zeta-2, Zeta-5, Eva, ... -
Performance of Myzus persicae (Hemiptera : Aphididae) clones on different host-plants and their host preference
(2003)The performance of eighteen clones of Myzus persicae (Sulzer) on pepper and tobacco plants at 20degreesC and L16:D8 and the choice of young adult apterae between tobacco and pepper leaf-discs were examined. The clones were ... -
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 ... -
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 ... -
Seasonal abundance and spatial distribution of the predator Macrolophus costalis and its prey Myzus persicae on tobacco
(2003)Field studies were conducted to assess the population and the spatial dynamics of the predatory bug Macrolophus costalis Fieber (Hemiptera: Miridae) and of its prey, the aphid Myzus persicae (Sulzer) (Hemiptera: Aphidoidea), ...
