“…Additionally, the maximum total area is only 12.56 ha for a centered sampling plot of L. striatellus, even at the 200 m radius buffer zone. In comparison with our study, previous studies were mostly conducted at larger spatial scales [4,27], because their research subjects had stronger flying or moving capabilities than L. striatellus. Even though the research subject belongs to the same family of Delphacidae (Delphacodes kuscheli) like our study, the spatial scale at the agricultural landscape had over 2000 m for a radius buffer [19,[28][29][30][31].…”

“…Landscape metrics were calculated in concentric ring buffers with a center radius of 50, 100, 150, and 200 m in each sampling plot using ArcGIS 10.0 (ESRI, 2010). The maximal radius was set at 200 m to avoid artificially large correlations due to overlapping buffers [27]. Landscape composition and configuration can affect planthopper dynamics independently and interactively [19,[28][29][30][31], the measures of landscape composition and configuration would be calculated in this study.…”

Abstract:The spatial distribution of crop and non-crop habitats over segmented agricultural landscapes could be used as a means to reduce insect pest populations. Seven land cover categories such as wheat, rapeseed, vegetable, water, built-up, paved road, and unsurfaced road were extracted from GeoEye satellite images dating from late May to late June of 2010. Three diversity metrics and three evenness metrics were estimated from the abovementioned land cover categories for quantifying the effect of landscape composition on nymphal and adult Laodelphax striatellus Fallén. The degree of correlation between the proportion of crop cover and adjacent spatial scales (r: 0.651-0.983) was higher than the correlation between the proportion of crop cover and nonadjacent spatial scales (r: −0.255-0.896). While the degree of correlation between diversity indices and abundance of L. striatellus decreased gradually when the spatial scales varied from large (>100 m radius buffer) to small (<100 m). Our study suggests that when using natural biological pest control and ecological engineering practices in the rural-urban fringes, the crop field's width should be less than 200 m and increasing vegetation diversity within such a scale will be helpful to regulate the insect pests under a certain density.

“…The laboratory populations cannot express the evolution promoted by modification of environment (Onstad, 2008). Moreover, insects are influenced by the agronomic practices (Ricci et al, 2009) and the dispersion of insects, as occurs between pests of peach and apple (Allen & Brunson, 1943). The genetic alterations caused by environmental parameters can be assessed by biological and biochemical parameters (Dres & Malet, 2002;Burd & Porter, 2006).…”

The use of laboratory insects for physiological studies, both genetic and toxicological, has become very common, but the continuous strains available in the laboratory for several generations without the insertion of genetic material can change the wild phenotypic and behavioral characteristics of the population compared with the field population. The aim of this research was to evaluate susceptility of field and laboratory Oriental Fruit Moth populations with the insecticide, based in toxicological, biochemical, and physicochemical characteristics. Experiments were conducted with four groups of chemical insecticides serving as chlorpyrifos, carbaryl, deltamethrin, and tebufenozide, with seven concentrations defined after pilot testing. Thereafter, the activity of acetylcholinesterase (AchE), glutathione S-transferase (GST), and Near Infrared Spectroscopy (NIRS) was evaluated. It was possible to detect differences between populations with regard to carbaryl and chlorpyrifos insecticides. The infrared analysis showed that the populations were distinct from each other, and they exhibit high activity of GST and AchE. The populations from both the field and the laboratory are different in their susceptibility to insecticides.

“…The spatial population dynamics of the codling moth can affect these control strategies in several ways (Mazzi and Dorn, 2012). Landscape, orchard and tree canopy structure influence codling moth dispersal at the local scale and thus its spatial population dynamics (Stoeckli et al, 2008;Ricci et al, 2009Ricci et al, , 2011. The selection of insecticide-resistant individuals in orchards under regular insecticide sprays could be reduced by immigration and gene flow of susceptible individuals from unmanaged areas (Basoalto et al, 2010, Fuentes-Contreras et al, 2014.…”

Body mass and wing geometric morphology of the codling moth (Lepidoptera: Tortricidae) according to sex, location and host plant in the region of Maule, Chile

Codling moth, Cydia pomonella (L.) (Lepidoptera: Tortricidae), is the key pest of apple and walnut production worldwide. Among other variables, successful management of this pest is dependent on adult dispersal at the local scale. Body mass and wing geometric morphology were evaluated on female and male codling moth adults collected from apple and walnut trees in three localities of the Region of Maule. Codling moth adults were obtained by rearing diapausing larvae collected from the field. Newly emerged adults were killed, and the total dry weight, thorax weight and abdomen weight were calculated. The wings were cleared and mounted for morphometric analyses: 15 and 11 characteristics of the fore and hind wings, respectively, were measured, including the meeting points of the veins and attaching points to the margins. In addition, wing length, area, loading, and aspect ratio were evaluated. As previously reported, females showed larger thorax, abdomen and total body mass, with longer, larger, and wider wings than males but with similar wing loading as males. The geometric morphology analysis also confirmed a sexual dimorphism in the fore and hind wings' size and shape. Significant differences in body mass and wing loading were found between localities, with morphological differences detected in the fore and hind wing shape but not in size. Host plant (apple and walnut) did not influence body mass, wing size or shape variables. Potential consequences of body mass and wing morphology differences on the dispersal and management of this major pest are discussed.
