“…Arthropods (i) are systematically more abundant in CT than in T (Holland and Reynolds, 2003;Rodríguez et al, 2006), however increasing herbicide quantity in a given CT system negatively affects arthropods (Pereira et al, 2007). Thus, strict insectivorous bird species (i.e.…”

Crops management is known to influence biodiversity, especially conservation tillage (CT, no-till) often found as a positive method compared to conventional tillage (T, inversion of soil) but without controlling for underlying farming practices. There are many ways to perform CT, in particular concerning the control of weeds, but few studies have taken into account these methods, which could explain the lack of consensus about the effect of CT compared to T. We tested differences in breeding birds abundance between CT and T while accounting for weed control methods in oilseed rape and wheat CT fields. During the intercrop period, one CT system used a cover crop to control weeds (CTcc), the other used herbicides (CTh) and the control (T) system only used a tillage. We made CTcc/T and CTh/T comparisons by sampling bird abundance (respectively 49 CTcc/51 T and 30 CTh/33 T point counts). We show substantial differences between CTcc/T and CTh/T comparisons as we detected greater bird abundances in CTcc than T for 5 species (2.3-4.1 times more individuals) and a lower abundance in CTh than T for 2 species (2.1-2.2 times less individuals). Our results demonstrate the importance to account for system features to ensure the CT efficiency for farmland birds, declining strongly in Europe since 1980 (-55 to-67%). Results also highlight an even more negative impact of herbicides than tillage, showing that stopping tillage to intensify herbicide use is not a promising way.

“…In all these studies, the activity of strictly insectivorous bats was measured during their foraging activity, known to be driven by arthropod availability (Charbonnier, Barbaro, Theillout, & Jactel, 2014;Hayes, 1997). Thus, the lack of consensus about effects of farming systems on bats could be linked to an effect of the gradient of practices on their arthropod prey, such as herbicides and tillage intensity (Evans, Shaw, & Rypstra, 2010;Pereira et al, 2007;Rodríguez, Fernández-Anero, Ruiz, & Campos, 2006;Taylor, Maxwell, & Boik, 2006). Although some studies revealed herbicide accumulation in bats along the farming intensification gradient (Bayat, Geiser, Kristiansen, & Wilson, 2014;Stechert, Kolb, Bahadir, Djossa, & Fahr, 2014), the relative effects of herbicide use and tillage intensity on crop attractiveness for bats remain unstudied.…”

The increased use of pesticides and tillage intensification is known to negatively affect biodiversity. Changes in these agricultural practices such as herbicide and tillage reduction have variable effects among taxa, especially at the top of the trophic network including insectivorous bats. Very few studies compared the effects of agricultural practices on such taxa, and overall, only as a comparison of conventional versus organic farming without accurately accounting for underlying practices, especially in conventional where many alternatives exist. Divergent results founded in these previous studies could be driven by this lack of clarification about some unconsidered practices inside both conventional and organic systems. We simultaneously compared, over whole nights, bat activity on contiguous wheat fields of one organic and three conventional farming systems located in an intensive agricultural landscape. The studied organic fields (OT) used tillage (i.e., inversion of soil) without chemical inputs. In studied conventional fields, differences consisted of the following: tillage using few herbicides (T), conservation tillage (i.e., no inversion of soil) using few herbicides (CT), and conservation tillage using more herbicide (CTH), to control weeds. Using 64 recording sites (OT = 12; T = 21; CT = 13; CTH = 18), we sampled several sites per system placed inside the fields each night. We showed that bat activity was always higher in OT than in T systems for two (Pipistrellus kuhlii and Pipistrellus pipistrellus) of three species and for one (Pipistrellus spp.) of two genera, as well as greater species richness. The same results were found for the CT versus T system comparison. CTH system showed higher activity than T for only one genus (Pipistrellus spp.). We did not detect any differences between OT and CT systems, and CT showed higher activity than CTH system for only one species (Pipistrellus kuhlii). Activity in OT of Pipistrellus spp. was overall 3.6 and 9.3 times higher than CTH and T systems, respectively, and 6.9 times higher in CT than T systems. Our results highlight an important benefit of organic farming and contrasted effects in conventional farming. That there were no differences detected between the organic and one conventional system is a major result. This demonstrates that even if organic farming is presently difficult to implement and requires a change of economic context for farmers, considerable and easy improvements in conventional farming are attainable, while maintaining yields and approaching the ecological benefits of organic methods.

O objetivo deste estudo foi contextualizar trabalhos publicados com manejo de solo e nutrição de plantas e seu efeito sobre a incidência, desenvolvimento do ciclo biológico e danos causados por insetos pragas em agroecossistemas. O manejo de solos e a nutrição de plantas são fatores importantes na determinação de ocorrência de pragas em agroecossistemas. Os solos com adoção de práticas ecológicas de manejo são apontados como fator importante na obtenção de plantas saudáveis. A nutrição de plantas de acordo com as recomendações regionais, aliado a adoção de adubação verde e orgânica, e plantio direto na palha, podem reduzir os surtos de insetos pragas. Dessa forma, as práticas de manejo de pragas devem considerar as intervenções realizadas no solo para reduzir o uso de agrotóxicos em sistema convencional, produção integrada e de insumos ecológicos em agricultura orgânica.
