“…Their maximum presence was between 17 and 31 May (Figure 1), with 624 individuals, of which 577 (93% of total) were aphids; in the following period, numbers were low and more or less uniform. The presence of aphids during this time interval is similar to that reported in different studies performed during spring, summer and autumnal dispersal all over Europe, carried out to monitor the diffusion of viruses possibly borne by these species (Dewar et al 1980;Taylor et al 1981;Tatchell et al 1988;Harrington et al 1990;Basky & Harrington 2000;Ferrara et al 2001;Coceano et al 2009). …”

Passive wind dispersal is one of the major mechanisms through which organisms disperse and colonise new areas. The detailed understanding of which factors affect this process may help to preserve its efficiency for the future. Despite its interest, the analysis of factors affecting the aeroplankton dispersal in urban environments is rare in literature. We sampled the aeroplankton community uninterruptedly every 4 hours from 17 May to 19 September 2011 in the urban garden of Parco d'Orléans, within the campus of the University of Palermo (Sicily). Sampling was performed by means of a JohnsonTaylor suction trap with automatised sample storing. Weather variables were recorded at a local meteorological station. Overall, 11,739 insects were caught during the present study, about 60% of which belonged to the order Hymenoptera, with particular presence of families Agaonidae and Formicidae. The suction trap also captured specimens of very small size, and in some cases, species caught resulted in new records for Italy. Composition and abundance of the aeroplankton community was influenced by alternation of day/night, as well as by daily fluctuations of climatic variables, for example fluctuating temperature. The taxonomic diversity of the samples was also studied, and was higher when the wind blew from the nearby green area. Our findings confirm that passive transport of arthropods strictly depends on weather conditions, and that the presence of natural areas within the urban environment significantly contributes to raising aeroplankton diversity, eventually fuelling overall biodiversity at a local scale.

“…For instance, the development of holocyclic populations is synchronized with the timing of bud burst and winged aphids are produced in the second and third generation on the primary hosts (Dicker 1940;Hiile Ris Lambers 1950). Also, effects of latitude on phenology may be shown through the gradual movements of winged aphids to the north, from southern areas where abundant winged aphids develop earlier (Dewar et al 1980). We found no significant relationships between soil moisture deficit or rainfall, and aphid phenology.…”

Daily samples between 1964 and 1991 from suction traps throughout Great Britain were used to study the migration phenologies of five aphid species: Brachycaudus helichrysi, Elatobiinn abietiuum, Metopolopbitim dirhodum, Myzus persicae and Sitobioft avenae, and their relationship with temperature. Regression relationships have been established between characteristics of aphid phenology and temperature, latitude and longitude for each species. There were differences between species in the period for which temperature was most strongly associated with aphid phenology. The study indicates that temperature, especially winter temperature, is the dominant factor affecting aphid phenology, for all five species. A 1 °C increase in average winter temperature advanced the migration phenology by 4-19 days depending on species. Effects of temperature on the aphid phenology are similar between holocyclic and anholocyclic species, unlike the effects of temperature on date of first flight record which have been previously shown to be important only in anholocyclic species.

“…These features of M. dirhodum flight activity seem to support the observation of PRIOR (1976); that M. dirhodum anholocyclic in Western Europe. However field observations showed that M. dirhodum is almost entirely holocyclic in England DEWAR et al (1980). The lack of autumn flight cannot be explained by the low population at Rothamsted, because an autumn flight occurred in 1991 when the total catch for the year was 413 individual and there were not any M. 1990-1997 Szolnok, andRothamsted ty peaks indicated that M. dirhodum alternates between Rosa and Gramineae.…”

“…This work has generally been done at national level until now (HARRING-TON, 1998) apart from few exceptions eg. DEWAR et al (1980). Based on the data of the suction trap network HARRINGTON et al (1990); showed that there is a strong statistical relationship between winter temperatures and subsequent phenology and abundance of anholocyclic species.…”

Cereal aphid flight was monitored by 12.2 m suction traps at Szolnok in the middle of the Great Hungarian Plain and at Rothamsted, UK. Flight activities of Rhopalosiphum padi, Metopolophium dirbodum and Sitobion avenae were compared by the cross correlation function (CCF) between Hungary and UK. There was significant synchrony between flight a‐tivity in Hungary and UK of R padi, M. dirbodum and S. avenae based on the eight years weekly sample data. The peak flight occurred 1, 3 and 2 weeks later at Rothamsted than at Szolnok for the three species (the CCF values were at – 1 week lag, r = 0.854, – 3 week lag r = 0.809, – 2 week lag r = 0.883, P < 0.05 respectively). When the flights in individual years were compared within species and between places the syn‐chrony was lowest for R. padi: – in 4 years out of 8 and there was no synchrony, in the other years when synchrony occurred the time lag varied between – 1 week and – 4 weeks. For M. dirhodum the time lag varied between 1 and – 5 weeks, the synchrony was the best for S. avenae the week lag varied between 0 and – 3 weeks. Our results show that flight activity of cereal aphids at Szolnok occurs 1‐3 weeks earlier than at Rothamsted. The crop season is earlier in Hungary than in England.
