“…GIS and geostatistics have opened up new ways to characterize distributions of insects (Park & Obrycki, 2004; Moral, 2007; Decante & van Helden, 2008) and can be of great help in understanding the biology of species in extended agro‐ecosystems such as P. leporinus . Understanding insect distribution also has practical implications for effective sampling and management programmes.…”

1 Cixiid planthoppers (Hemiptera: Fulgoromorpha: Cixiidae) are considered to be important economic pests because of their ability to transmit phloem-restricted prokaryotes causing emerging plant diseases worldwide. However, little information is available on the biology and ecology of such species. This is the case for Pentastiridius leporinus (Linnaeus), a cixiid planthopper reported to live on common reed across Countries of Central and Northern Europe. However, in the east of France, the same planthopper species appears to complete its life cycle in the sugar beet-wheat cropping system and has been repeatedly shown to transmit prokaryotic plant pathogens that are associated with an emerging disease of sugar beet called syndrome 'basses richesses'. 2 To gather evidence on the biology of the planthopper in the cropping rotation, we analysed the flight activity of adults. We used transparent sticky traps for sampling migrating adults and quantified nymphs as well as emerging adults on the roots of wheat plants. 3 Results showed a significant correlation between disappearance of nymphs and emerging adults from wheat roots and the occurrence of migrant adults in nearby sugar beet fields. Planthoppers migrated more abundantly and colonized sugar beet for longer periods than any other crop available. Flight activity was very pronounced during the migratory phase that was extended from the middle of June to the middle of July. A geographic information system and geostatical analysis revealed that planthoppers flew and colonized the centre of the sugar beet field rather than the borders. 4 Overall, results obtained in the present study suggest that the ecology and biology of the planthopper vector in the cropping rotation is a primary factor that leads to the emergence of the syndrome 'basses richesses' disease of sugar beet.

“…Further, the distribution can change according to the insects' developmental stage, the season, the phenological status of the crop, and the weather conditions. For example, alternating periods of clumped and random patterns were observed to be recurrent in fruit orchards and vineyards for leafhoppers, thrips, and fruit flies (Nestel & Klein 1995;Papadopoulos et al 2003;Farias et al 2004;Decante & van Helden 2008;Rhodes et al 2011). Consequently, in situ observations are necessary to depict the spatio-temporal dynamics of a pest and descriptive maps must be developed to have a visual representation of pest presence in the agro-ecosystem.…”

Sciarretta A., Trematerra P. (2014): Geostatistical tools for the study of insect spatial distribution: practical implications in the integrated management of orchard and vineyard pests. Plant Protect. Sci., 50: 97-110.Spatial heterogeneity in agricultural systems is recognised as an important source of variability to be investigated. In the evolution of Integrated Pest Management (IPM), patterns and processes that influence spatio-temporal dynamics in insect populations tend to assume more importance compared to the classical theory. Geostatistics represent a valuable tool to investigate the spatial pattern of insect populations and to support pest control. After an explanation of the geostatistical analysis, in the present paper we provided an overview of practical applications in managing pests, focusing on fruit orchards and vineyards. The utility of geostatistical tools is illustrated with examples taken from field studies, with attention to the analysis of spatial patterns, monitoring schemes, use of traps, scale issues, precision targeting, and risk assessment maps. Potential approaches in the context of IPM are discussed in relation to future perspectives.

“…The tea green leafhopper, Empoasca vitis G€ othe (Hemiptera: Cicadellidae), is a serious pest of the tea plant, Camellia sinensis (L.) O. Kuntze (Theaceae), in tea-producing countries in Asia, e.g., China, Japan, India, and Vietnam (Hazarika et al, 2009;Jin et al, 2012a). This piercing-sucking herbivore is also an important grapevine pest in southern Europe, including France, Switzerland, Italy, and Greece (Candolfi et al, 1993;Decante & van Helden, 2008;Pavan & Picotti, 2009). In Chinese tea plantations, E. vitis adults and nymphs feed solely on the young tea shoots and generally occur in 9-11 overlapping generations throughout the growing season of the tea plants (Feng et al, 2004;Pu et al, 2005).…”

The tea green leafhopper, Empoasca vitis G€ othe (Hemiptera: Cicadellidae), is a serious pest of tea crops in China. The effectiveness of five aromatic non-host plants, Corymbia citriodora (Hook.) (Myrtaceae), Ocimum basilicum L. (Lamiaceae), Lavandula pinnata L. (Lamiaceae), Ruta graveolens L. (Rutaceae), and Rosmarinus officinalis L. (Lamiaceae), was investigated to determine their ability to suppress E. vitis on tea plants. Volatile organic compounds derived from L. pinnata, R. officinalis, and C. citriodora were found to repel leafhoppers and to mask the host's odors. Intercropping L. pinnata and C. citriodora with tea plants significantly reduced the E. vitis population levels in the tea plantation associated with higher population densities of generalist predators. The volatile compounds from the five non-host plants were collected by headspace absorption under field conditions, and the 10 major components were identified. Qualitative and quantitative differences were found among the five odor profiles. Moreover, the emission dynamics of non-host volatiles were monitored. Non-host volatile emissions showed two peak periods, one in the spring and one in the autumn period. These peaks were almost consistent with the population dynamics of E. vitis. Our findings suggested that this newer approach to ecologically based, sustainable pest management implemented via intercropping with non-host aromatic plants such as L. pinnata and C. citriodora offers a promising alternative to chemical control of the leafhopper population.
