Geostatistics and Geographic Information System to Analyze the Spatial Distribution of the Diversity of Anastrepha Species (Diptera: Tephritidae): the Effect of Forest Fragments in an Urban Area

Abstract

Fruit flies are among the most damaging insect pests of commercial fruit in Brazil. It is important to understand the landscape elements that may favor these flies. In the present study, spatial data from surveys of species of Anastrepha Schiner (Diptera: Tephritidae) in an urban area with forest fragments were analyzed, using geostatistics and Geographic Information System (GIS) to map the diversity of insects and evaluate how the forest fragments drive the spatial patterns. The results indicated a high diversity of species associated with large fragments, and a trend toward lower diversity in the more urbanized area, as the fragment sizes decreased. We concluded that the diversity of Anastrepha species is directly and positively related to large and continuous forest fragments in urbanized areas, and that combining geostatistics and GIS is a promising method for use in insect-pest management and sampling involving fruit flies.

Geological Resource Planning and Environmental Impact Assessments Based on GIS

“…GIS can integrate the unique visualization effect and geographic analysis function of a map with general database operations (such as query and statistical analysis) to map and analyze the phenomena and events on the earth [3]. It is divided into five parts: personnel, data, hardware, software, and process [4]. The method of geological resource planning involves correctly and reasonably arranging and designing land resources within a certain range [5].…”

Spatiotemporal analysis of distribution of pest and predator in corn crops

“…Pest sampling works can be seen in FARIAS et al (2001a). The use of spatial models is already commonly used in the literature, as can be seen in FARIAS et al (2001b), DUARTE et al (2015), GARCIA et al (2017), MEHRJARDI et al (2008), among others. A more complete approach is time-space analysis, which uses robust models to describe and predict pest incidence by studying space-time dynamics together.…”

New records of Anastrepha Schiner, 1868 (Diptera, Tephritidae) in an urban forest fragment in Manaus, Amazonas, Brazil

“…The geographic diversity of Anastrepha species is related directly and positively to the size and continuity of forest fragments in urbanized areas (Garcia et al 2017). Araujo et al (2019) compared two sampling methods (trapping and fruit sampling) on the campus of the Luiz de Queiroz College of Agriculture (ESALQ; Piracicaba, São Paulo, Brazil), and discussed that although fruit sampling has resulted in a greater diversity and abundance of species, it did not adequately represented the composition of the Anastrepha species in the area.…”
