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 ... -
Altered GPI modification of insect AChE improves tolerance to organophosphate insecticides
(2011)The olive fruit fly Bactrocera oleae is the most destructive and intractable pest of olives. The management of B. oleae has been based on the use of organophosphate (OP) insecticides, a practice that induced resistance. ... -
Are citrus species favorable hosts for the Mediterranean fruit fly? A demographic perspective
(2009)We studied, under laboratory conditions, demographic parameters of adult Mediterranean fruit flies, Ceratitis capitata (Wiedemann) (Diptera: Tephritidae) (medfly), obtained from three sweet orange varieties, lemon, and ... -
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 ... -
Behavioral interactions between Sitophilus zeamais and Tribolium castaneum: the first colonizer matters
(2015)There is lack of knowledge on the interactions between kernel aging and the simultaneous infestation by insects, both internal and external feeders. In the present paper, we report results obtained in arena-olfactometer ... -
Behavioral responses of Sitophilus zeamais Motschulsky adults to conditioned grain kernels
(2013)Laboratory experiments were conducted in order to assess the intra- and inter-specific interactions in cereal kernels and behavioral responses of maize weevil (Sitophilus zeamais) adults. For that purpose, conditioning of ... -
Bioactivity of five monoterpenold vapours to Tribolium confusum (du Val) (Coleoptera : Tenebrionidae)
(2007)Five monoterpenoids (terpinen-4-ol, 1,8-cineole, linalool, R-(+)-limonene and geraniol) were tested in vapour form against different stages of Tribolium confusum. Terpinen-4-ol (with LC(50) values ranging between 1.1 and ... -
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 ... -
Comparison of spinosad with three traditional grain protectants against Prostephanus truncatus (Horn) and Ephestia kuehniella (Zeller) at different temperatures
(2013)The insecticidal effects of deltamethrin, chlorpyriphos-methyl, pirimiphos-methyl, and spinosad were evaluated against adults of Prostephanus truncatus (Horn) (Coleoptera: Bostrychidae) and larvae of Ephestia kuehniella ... -
Comparison of two pirimiphos-methyl formulations against major stored-product insect species
(2013)The insecticidal effect of two pirimiphos-methyl formulations [emulsifiable concentrate (EC) and capsule suspension (CS)] was evaluated in laboratory bioassays against adults of Sitophilus granarius, S. oryzae, Rhyzopertha ... -
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 ... -
Cross-amplified microsatellites in the European cherry fly, Rhagoletis cerasi: medium polymorphic-highly informative markers
(2011)The European cherry fruit fly, Rhagoletis cerasi (Diptera: Tephritidae), is a major pest of cherries in Europe and parts of Asia. Despite its big economic significance, there is a lack of studies on the genetic structure ... -
Cyclocephala (Coleoptera: Scarabaeidae: Dynastinae) evolution in Lesser West Indies indicates a Northward colonization by C. tridentata
(2012)A dual cytogenetic and molecular analysis was performed in four species of Cyclocepala (Coleoptera: Scarabaeidae: Dynastinae) from Lesser Antilles (Martinique, Dominica and Guadeloupe). Two species/sub-species, C. mafaffa ... -
Degradation and adsorption of terbuthylazine and chlorpyrifos in biobed biomixtures from composted cotton crop residues
(2010)BACKGROUND: Biobeds have been well studied in northern Europe, whereas little is known regarding their use in southern Europe. The degradation and adsorption of terbuthylazine (TA) and chlorpyrifos (CP) were studied in ... -
