Adult emergence rhythm of the egg-parasitoid Telenomus busseolae
(1998)The adult emergence rhythm of Telenomus busseolae, an egg parasitoid of Sesamia nonagrioides, was examined when parasitoids were exposed to different light-dark regimes. Most of the adult parasitoids emerged throughout the ... -
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 ... -
Biological characteristics of the mirids Macrolophus costalis and Macrolophus pygmaeus preying on the tobacco form of Myzus persicae (Hemiptera : Aphididae)
(2003)Biological and population parameters of the predatory bugs Macrolophus costalis Fieber and Macrolophus pygmaeus Rambur preying on the tobacco aphid Myzus persicae (Sulzer) were examined. Tobacco was used as host plant and ... -
Centaur database: an information system for aphid surveys and pest control
(2003)The development and the use of an information system (Centaur) including aphid trapping data from suction and yellow traps are described. Centaur is a client-server database on an NT server and the interface is in Windows. ... -
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 ... -
Comparing the genetic structure of codling moth Cydia pomonella (L.) from Greece and France: long distance gene-flow in a sedentary pest species
(2012)Codling moth Cydia pomonella L. (Lepidoptera: Tortricidae) is the most important insect pest of apple production in Europe. Despite the economic importance of this pest, there is not information about the genetic structure ... -
A contribution to the aphid fauna of Greece
(2007)In the present study a list of the aphid species recorded in Greece is provided. The list includes records before 1992, which have been published in previous papers, as well as data from an almost ten-year survey using ... -
Development of an optimum sampling plan for the population of Aphis gossypii (Hom., Aphididae) on cotton in Greece
(1996)A sampling plan was developed for the study of the population dynamics of Aphis gossypii, Glover on cotton. The distribution of the population of A. gossypii within the plant is not randomly distributed in relation to ... -
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, ... -
Diapause Termination in Sesamia nonagrioides (Lepidoptera: Noctuidae) under Laboratory and Field Conditions
(1998)The influence of photoperiod and temperature on the termination of diapause of Sesamia nonagrioides (Levebvre) was evaluated under laboratory and field conditions. Long-day photoperiod enhanced termination of diapause. ... -
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 ... -
Dispersal ability in codling moth: mark-release-recapture experiments and kinship analysis
(2012)1 The present study focused on the dispersal patterns in the codling moth because such information is fundamental for determining the dynamics and genetics of the pest populations and for developing efficient management ... -
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 larval density on development and diapause of Sesamia nonagrioides (Lef.) (Lep., Noctuidae) under laboratory conditions
(1999)The effect of larval density on development and diapause of Sesamia nonagrioides (Lef.) was examined. Larvae were grown on an artificial diet at densities of five, 10, 20, 30 and 40 larvae per box, under two environmental ... -
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 ... -
Effects of Short- and Long-Day Photoperiods on Growth and Development of Sesamia nonagrioides (Lepidoptera: Noctuidae)
(1996)The effects of 2 photoperiods, a diapause-inducing (10:14 [L:D] h) and a non-diapause inducing one (16:8 [L:D] h) at 25°C on the growth and development of larvae of the corn stalk borer, Sesamia nonagrioides, were investigated. ... -
