“…Although pesticide effects on ants in agroecosystems vary greatly depending on the type of pesticide and the species considered (Wilson et al ., ; Pereira et al ., ; Greenslade et al ., ), several studies have reported a lack of response in ants to sprayed chemicals (Wang et al ., ; Michereff‐Filho et al ., 2002; Matlock & de la Cruz, ; Kwon et al ., ). Others have found a significant reduction of ant diversity and abundances in agroecosystems treated with pesticides (Perfecto, ; Matlock & de la Cruz, ; Pereira et al ., ) or herbicides (Sonoda et al ., ). Insecticides do not affect all ant species equally (Michereff‐Filho et al ., 2002; Badji et al ., ) or lead to the dominance of a small number of ant species (Perfecto, ; Roth et al ., ; Perfecto & Snelling, ; Baraibar et al ., ).…”

1 Tropical small-holder farmers rely on sustainable food production. Crop seed predation by ants can cause substantial yield loss and result in high pesticide use. 2 We conducted field experiments and questionnaire-based surveys aiming to assess the effect of sown-seed predation on four crop species (Cucumis sativus, Daucus carota, Capsicum frutescens and Solanum melongena) in 15 vegetable gardens and the resulting impact on the net income of Indonesian farmers. Furthermore, we tested a commonly applied insecticide and herbicide for seed, seedling and plant protection aiming to understand their effect on ant seed predation. 3 We found that the mean percentage of seeds removed per garden was 42.0%, 49.4%, 48.0% and 50.6% for C. sativus, D. carota, C. frutescens and S. melongena, respectively, halving the farmers' income after considering initial and operational costs. Insecticide and herbicide treatments did not affect seed predation success or overall ant abundance, although they had positive and negative effects on ant species-specific abundance. 4 High overall ant abundance caused high seed predation rate in all gardens as a result of a functional redundancy of ant species, which compensated for pesticide-related species loss. 5 Environmentally-friendly and more sustainable practices such as overseeding or seedling production in nurseries could substitute for these inefficient approaches of chemical pest control, although this requires further research.

“…This effect is possibly due to the limited food sources of the species in cities and farmland. Moreover, the use of pesticides in farmlands can also affect insects (Sonoda, Izumi, Kohara, Koshiyama, & Yoshida, 2011), likely affecting the identification of hosts by M. alternatus and inhibiting dispersal.…”

Pine wilt disease (PWD), Bursaphelenchus xylophilus, is an extremely threatening invasion forest disease throughout the world, especially in Asia. B. xylophilus is spread in Asia by vector beetles of Monochamus alternatus, which has long no effective control method. Understanding of landscape effects on the dispersal and outbreaks of forest pests is crucial to establishing effective ecological control strategies. Here, we analyzed the samples of M. alternatus collected at landscapes in order to estimate the effects of landscape types on the genetic structure and dispersal of M. alternatus. The landscapes included the geographical scales, forest types and land uses. The individuals of M. alternatus were genotyped by using whole-genome resequencing. Population genetic structures were clearly differentiated at the intermediate scale, suggesting the intermediate scale is an effective barrier against natural dispersal of M. alternatus. We used the least-coat distances, least-cost transect analysis, and distance-based redundancy analysis to estimate the effects of forest types and land uses within the fine scales. The results showed that the gene flow and genetic diversity were positively correlated with host and mixed forests, whereas negatively with non-host forests. Among land-use landscapes, the roads had the positive effect on gene flow and genetic diversity but farmland and urban uses had negative effects. This highlights that human-mediated transport via roads was likely to be the main factor leading to the long-distance invasion of M. alternatus, whereas non-host landscapes could suppress the spread of this species. These findings may be useful to control the PWD dispersed by M. alternatus.

“…Many ground beetles are capable of flying and can disperse widely (Thiele, 1977) and are thus adapted to rivers with natural dynamics. As such, ground beetles have been used in numerous biodiversity studies in forest (Magura et al, 2001;Richard, 2004), in poplar plantations (Allegro & Sciaky, 2003;Denux et al, 2007;Elek et al, 2010), in agricultural areas (Liu et al, 2010;Sonoda et al, 2011;Holland et al, 2012), and in alluvial areas (Lambeets et al, 2008;Januschke et al, 2011). In alluvial areas, sand and gravel sediment bars are important for ground beetles (Lachat et al, 2001), where they are good bio-indicators for the management and restoration of river ecosystems (Gerisch et al, 2006;Januschke et al, 2011;Januschke & Verdonschot, 2016) and hydrological conditions (Gerisch et al, 2006).…”

Abstract. 1. The Loire River is one of the last European large rivers with important sediment dynamics and numerous sandbanks. The extraction of sediment from the riverbed during decades and the construction of levees for flood prevention have strongly affected and shaped the biodiversity of the Loire River.2. Many species from pioneer riverbanks have been impacted with particular consequences for psammophilous insects. The ground beetle Harpalus (Acardystus) flavescens (Piller & Mitterpacher, 1783), is considered to have disappeared from the Middle Loire River for 40 years and is endangered everywhere in Europe.3. In 2012 and 2013, we recorded two specimens of H. flavescens in R egion Centre-Val de Loire (France), in the course of a survey dedicated to evaluating the impact of fluvial maintenance operations upon sediment and biodiversity dynamics.4. The presence of H. flavescens may be linked to the interruption of riverbed extractions and the vegetation removal of sandbanks of the Loire River (ecosystem restoration).
