Detection and characterization of phytoplasmas infecting tomato plants in Greece
(2007)Over the course of the 2005 and 2006 growing seasons, surveys were carried out in tomato fields in different parts of Greece in order to determine the occurrence and distribution of phytoplasma diseases of tomato, and to ... -
Detection and geographical distribution of the organophosphate resistance-associated Delta 3Q ace mutation in the olive fruit fly, Bactrocera oleae (Rossi)
(2014)BACKGROUND The olive fruit fly, Bactrocera oleae (Rossi) (Diptera: Tephritidae), is the most important pest of olives. Its control is based mostly on organophosphate (OP) insecticides, a practice that has led to resistance ... -
Diapause completion in the almond seed wasp, Eurytoma amygdali (Hymenoptera : Eurytomidae) following early low temperature treatment
(2006)Fruit of two almond, Primus amygdahis Linnaeus, cultivars (Retsou and Truoito) containing diapausing larvae of Eurytoma amygdali Enderlein, were collected in early August from coastal areas in northern Greece. Some larvae ... -
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 ... -
Does natal habitat preference modulate cereal kernel preferences in the rice weevil?
(2013)The influence of larval diet source in Sitophilus oryzae (L.), a primary grain feeder, on the choice of a new cereal host by young adult was investigated through a multiple choice comparative bioassay. For this purpose, ... -
Dual reproductive cost of aging in male medflies: Dramatic decrease in mating competitiveness and gradual reduction in mating performance
(2011)Although age-based effects on the reproductive success of males have been reported in several animal taxa the cost of aging on male mating success in lekking species has not been fully explored. We used the Mediterranean ... -
Effect of cotton cultivars on the oviposition preference of pink bollworm (Lepidoptera: Gelechiidae)
(2010)The effect of four cotton cultivars on the oviposition behavior of the pink bollworm Pectinophora gossypiella (Saunders) was studied under laboratory and semi-field conditions. Young plants and bolls from four commercial ... -
Effect of Diet on Development and Reproduction of Pezothrips kellyanus (Thysanoptera: Thripidae)
(2010)The developmental time, fecundity, and longevity of Pezothrips kellyanus (Bagnall) (Thysanoptera: Thripidae) encaged on lemon, Citrus limon (L.) Burm.f., leaves supplied with different food sources (pollen, sucrose, and ... -
Effect of elevation on spatio-temporal patterns of olive fly (Bactrocera oleae) populations in northern Greece
(2008)The spatio-temporal patterns of olive fly populations in a managed olive-growing region in the area of Chalkidiki in northern Greece were followed during 2005. The trapping grid consisted of 700 traps. Throughout the growing ... -
Effect of Short Exposures to Spinetoram Against Three Stored-Product Beetle Species
(2012)Laboratory bioassays were carried out to evaluate the effectiveness of two formulations of spinetoram, water dispersible granules (WG), and suspension concentrate (SC-NC), against three major stored-grain beetle species, ... -
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 and relative humidity on the efficacy of spinetoram for the control of three stored product beetle species
(2013)The effect of temperature and relative humidity (r.h.) on the efficacy of spinetoram on wheat was investigated against three stored product insect species. Laboratory bioassays were conducted on wheat in all combinations ... -
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 ... -
Effect of Temperature on the Development and Longevity of Pezothrips kellyanus (Thysanoptera: Thripidae)
(2009)The developmental biology and adult longevity of Pezothrips kellyanus (Bagnall) (Thysanoptera: Thripidae) on lemon (Citrus limon L.) leaves was studied at five constant temperatures (15, 20, 25, 30, 32.5, and 35 degrees ... -
Effect of uneven distribution of spinetoram-treated wheat and rice on mortality and progeny production of Rhyzopertha dominica (F.), Sitophilus oryzae (L.) and Tribolium confusum Jacquelin du Val
