Photoperiodic sensitivity was no longer detected after late January. Short-day photoperiod maintained diapause for larvae sampled until late January.

Each trapping station consisted of a Jackson trap (baited with trimedlure) and a McPhail trap (baited with ammonium acetate, putrescine, and trimethylamine). More males than females were captured throughout the season. Males and females exhibited different spatial dispersion patterns. Females were first detected during the summer (June-July) in apricot and peach trees bearing ripe fruits and significantly aggregated there toward the end of July. In the autumn, females significantly aggregated in apple orchards bearing mature fruits. Early aggregations of males were first detected in August in cherries and plums. In September, males significantly clustered in pears at the edges of the orchard, and by October, after an increase in population density, their spatial dispersion pattern became random (no significant spatial autocorrelation). At the end of the season (November), the dispersion of both sexes became random. Our results show that spatial autocorrelation statistics can provide an important tool in studying the spatial dynamics of this fly even in small orchards. Results also suggest that the incorporation of knowledge on spatial patterns into area-wide control projects may improve monitoring efforts and reduce program costs.}, keywords = {Host phenology, Mixed fruit orchard, Moran{\textquoteright}s I, Spatial autocorrelation, Spatial dispersion patterns}, author = {Papadopoulos, N.T. and Katsoyannos, B.I. and Nestel, D.} } @article {7256, title = {Spatial pattern of Saissetia oleae (Homoptera: Coccidae) in Greece}, journal = {Environmental EntomologyEnvironmental Entomology}, volume = {26}, number = {6}, year = {1997}, note = {TY - JOURExport Date: 7 September 2006Source: ScopusReferences: Argyriou, L.C., Studies on the morphology and biology of the olive black scale (Saissetia oleae Bernard) in Greece (1963) Ann.

The results indicated that the distribution of S. oleae was highly aggregated and the degree of aggregation changed considerably during the generation, as indicated by the values of the exponent k of negative binomial distribution and the I{\"a} index of aggregation. Aggregation increased during the ovipositional period in summer and during winter, whereas it decreased during autumn and spring. The increased aggregation during summer was caused by the combined effect of crawler behavior as they searched for settlement, and of mortality, which is negatively related to population density. During autumn, and possibly during spring when the main action of natural enemies occurred, the reduced aggregation was caused by the direct density dependence of mortality. This relationship was determined to a certain extent by the action of the internal parasitoid Metaphycus helvolus (Compere). The increased aggregation during winter was attributed to an inverse density-dependent relationship between mortality and population density and also to larval movement from leaves to branches. A strong relationship between the mean and variance of population density (Taylor power law) was established with 2 types of sampling units (leaf, branch). The corresponding 2 values of the coefficient b were remarkably similar. However, the exponent k of negative binomial and the Morisita index of aggregation (I{\"a}) were found best to describe changes in the spatial pattern during the generation compared with the Taylor relationship.}, keywords = {mortality, Saissetia oleae, Spatial pattern}, author = {Kapatos, E.T. and Stratopoulou, E.T. and Sahinoglou, A.} } @article {6822, title = {Use of geostatistical analysis to characterize the spatial distribution of Lobesia botrana (Lepidoptera: Tortricidae) larvae in northern Greece}, journal = {Environmental EntomologyEnvironmental Entomology}, volume = {35}, number = {2}, year = {2006}, pages = {497{\DH}506}, author = {Ifoulis, A.
