<abstract xmlns="http://www.w3.org/1999/xhtml">A prototype for pest development stages forecasting is developed in Kazakhstan exploiting data from the geoinformation technologies and using codling moth as a model pest in apples. The basic methodology involved operational thermal map retrieving based on MODIS land surface temperature products and weather stations data, their recalculation into accumulated degree days maps and then into maps of the phases of the codling moth population dynamics. The validation of the predicted dates of the development stages according to the in-situ data gathered in the apple orchards showed a good predictivity of the forecast maps. Predictivity of the prototype can be improved by using daily satellite sensor datasets and their calibration with data received from a network of weather stations installed in the orchards.</abstract>

<abstract xmlns="http://www.w3.org/1999/xhtml">The interactive relationship between the root–knot nematode <italic>Meloidogyne incognita</italic> and the root-rot fungus <italic>Macrophomina phaseolina</italic> in a root–rot disease complex of chickpea (<italic>Cicer arietinum</italic> var. <italic>avrodhi</italic>) was studied in a net house. The present study was carried out in such a manner so that the pathogenic potential of <italic>M. incognita</italic> and <italic>M. phaseolina</italic> individually, simultaneously and sequentially could be monitored. The pathogens singly as well as in combination led to significant reduction in growth, yield, nutrient and biochemical parameters. Gaseous exchange parameters like photosynthetic rate, transpiration rate and stomatal conductance were also reduced following infection of plants by the pathogens. However, maximum reduction was noticed in simultaneous inoculation with both pathogens. Sequential inoculation, where <italic>M. incognita</italic> preceded <italic>M. phaseolina</italic> by 15 days, was more damaging to the crop in comparison to that where <italic>M. phaseolina</italic> preceded <italic>M. incognita</italic> inoculation by 15 days. Infection by <italic>M. phaseolina</italic> caused a considerable reduction in the number of galls, egg–masses and nematode multiplication, with the highest reduction observed in plants simultaneously inoculated with the pathogens. Those plants also showed the highest disease severity in terms of percent root–rot. Thus, a manifold action plan to reduce the impact of the root-rot disease complex on chickpea crops has to be formulated.</abstract>

<abstract xmlns="http://www.w3.org/1999/xhtml">The present study is part of a survey for the identification of plant-parasitic nematodes in the rhizosphere of cultivated and wild olive trees in Crete, Greece. Sixteen species corresponding to 13 genera are added to 20 species belonging to 8 genera, previously reported in the survey. Seven nematode species, <italic>Filenchus ditissimus</italic>, <italic>Filenchus vulgaris</italic>, <italic>Ogma civellae</italic>, <italic>Pratylenchoides crenicauda</italic>, <italic>Psilenchus hilarulus</italic>, <italic>Tylenchus elegans</italic>, and <italic>Zygotylenchus guevarai</italic>, are recorded for the first time in Greece.</abstract>

<abstract xmlns="http://www.w3.org/1999/xhtml">The mite fauna in foliage and litter of a sprayed alfalfa hay field with the acaricide-insecticide bifenthrin, was studied based on monthly samplings from foliage and litter in Central Greece between 2008–2009. Potential differentiations between this field and two adjacent alfalfa hay fields, which were not subjected to pesticide applications and were managed with different number of cuttings, were also evaluated in terms of population fluctuation over time, population density, species richness, diversity and spatial distribution. The sprayed field hosted 50 and 68 species and morphospecies in foliage and litter respectively, depicting high relative abundance of oribatid and prostigmatic mites. <italic>Neoseiulus aristotelisi</italic> Papadoulis, Emmanouel and Kapaxidi, was a new record for alfalfa, previously found in rice in Macedonia, Greece. The seasonal fluctuation of mites, particularly in foliage, was similar in all fields. The spatial distribution of a <italic>Zygoribatula</italic> species, which was common and dominant in all fields, was also aggregated. Finally, the sprayed field shared similar mite diversity with the two non-sprayed fields, but not similar species richness.</abstract>

<abstract xmlns="http://www.w3.org/1999/xhtml">Mating disruption (MD) has been a successful approach for pest control of several lepidoptera. Field trials to evaluate the efficacy of communication disruption of low pheromone load formulation on <italic>Thaumetopoea pityocampa</italic> were carried out in 2010 and 2011 in an urban park. The efficacy of MD was assessed by comparing male <italic>T. pityocampa</italic> catches in pheromone traps, between MD and Control areas. In the 1st year of the application the percentage of male inhibition ranged from 85 to 100% during the 1st month of the flight period and 95-100% during the whole flight period in the 2nd year. The pheromone remained in the polymeric matrix was almost 30% after 7 weeks under laboratory aging conditions. Combining the pheromone release results with the male disorientation results we can assume that after 7 weeks the remaining pheromone concentration was still sufficient to achieve MD. This study indicates that air permeation with the major sex pheromone component (<italic>Z</italic>)-13-hexadecen-11-ynyl acetate, at a rate of 20 g/ha for one application per season, can affect the orientation of <italic>T. pityocampa</italic> males. Since mating disruption is an environmentally safe method for pest control, it could be a valuable tool to control <italic>T. pityocampa</italic> in urban areas and parks.</abstract>
