Full textMixed fruit-tree-vegetable plots are diversified, agroforestery plot associating fruit trees and vegetables. In this type of cropping systems, the whole available 3D space is used to produce food based on vegetables at the ground level and on fruits at several heights. Mixed fruit-tree-vegetable plots are thus a possible response to the limited available space for agricultural areas.Moreover, conservation biological control, i.e. control of pests by their naturally occurring predators, is frequently increased in diversified plots although results seem to be context-dependent. The objective of this PhD thesis is to understand the mechanisms governing conservation biological control of vegetable pests in mixed fruit-tree-vegetable plots. As mixed fruit-tree-vegetable plots are diverse and their structure can be complex, we chose to base our study on the comparison of these mechanisms in experimental plots. Two plots mimic a simplified mixed fruit-tree-vegetable orchard associating apple trees and cabbages, and two control plots are vegetable monocultures. All plots were pesticide-free and the experiment was carried out during one growing season. First of all, we compared abundances of the cabbage pests and their predators, between fruit-tree-vegetable plots and vegetable monocultures. Combining pest and predator monitoring, an exclusion experiment and a model of pest population dynamics, we compared the predation rate, the survival rate and the immigration rate of the pests between the two plot types. Then, we focused on the predation function and on the ground predator community. We investigated if the fruit-tree-vegetable plots fostered the emergence of an efficient predator community, i.e. a community with 1) high abundances, 2) high complementarity, 3) low intraguild predation and 4) including key-stone species or functional groups that were high consumers of pests. According to our results, most of the vegetable pests, i.e. Myzus persicae, caterpillars, and white flies, but not the cabbage grey aphid Brevicoryne brassicae, were more abundant in mixed fruit-tree-vegetable plots . The pest survival rate was higher in mixed fruit-tree-vegetable plots and immigration was lower for one pest. Differences in predation rates between mixed fruit-tree-vegetable plots were pest dependant. For Myzus persicae and the caterpillars, predation rate was higher in monocultures whereas for Brevicoryne brassicae, it was higher in mixed fruit-tree-vegetable plots. Concerning the predator community, we found that, 20% of predator species were less abundant in mixed fruit-tree-vegetable plots. The species richness, the Shannon diversity, the equitability were also lower. The wolf spider Pardosa proxima was the only species with a positive impact on predation rate and only in mixed fruit-tree-vegetable plots. Lower predation rate of Myzus persicae and caterpillars in mixed plots were thus possibly explained by the fact that the predator community was less rich and thus less efficient. Predation in mixed fruit-tree-vegetable plots may thus be mainly due to just few species that are high pest consumers, which would have a greater impact on aggregated pests such as Brevicoryne brassicae. This PhD thesis results provides a first hint of mechanisms ruling pest control in a simplified mixed fruit-tree-vegetable plot and for one culture season, which can serve as a basis to plot design optimising pest control

Full textPhytoseiid mites are the most widespread predatory mites in agrosystems and some species are efficient to control phytophagous mite outbreaks. The aim of this work is to determine, in an experimental site in the South of France, the influence of Sorbus domestica and Pinus pinea co-planted in vine plots on the structure of Phytoseiidae occurring on vines. Before realising samplings, several experiments (morphological and molecular analyses) and hybridization were made under laboratory conditions to answer a taxonomic interrogation concerning the occurrence in the site of study of two real species, Typhlodromus exhilaratus and T. Phialatus, morphologically very close. The results of these experiments showed that the two species are not synonyms and can be distinguished morphologically only by the spermatheca or insemination apparatus shape (genital organ of females). Results of samplings (2003-2005) showed the occurrence of Phytoseiidae on vines and on co-planted trees. The densities of these predators on vine seem to be positively affected by the presence of trees particularly in 2005. However, diversity of Phytoseiidae does not seemed to be affected by the plantations of trees inside vine crops. Typhlodromus exhilaratus was the dominant species in vine plots (with trees or not) and on co-planted trees. Population exchanges of this species between vines and co-planted trees seem to be possible. Pinus pinea could be more favourable host plant to phytoseiid mites than S. Domestica on which very low densities of these predators were observed. The present work also showed the dominance of T. Phialatus in monocultural plots with trees and also in uncultivated areas surrounding vine crops. The interspecific competition and especially the side effects of pesticides applied on vine seem to be among factors tested in the present work the two more interesting for explaining the spatial segregation observed of T. Exhilaratus and T. Phialatus. Thus, plantation of trees inside vine crops could have many applied implications on biological control by conservation of the biodiversity and habitats and the durability of the agrosystems. However many studies remain necessary to have more information about biotic and abiotic factors affecting the occurrence and the development of these predators and their movement between the differents parts of the agrosystem and on the other hand the possibility to generalize the results of these studies to other sites and on other biological models especially others beneficials

Full textMulti-trophic interactions play a key role in structuring agro-ecosystems and regulating arthropod population dynamics. The objective of the PhD was (i) to study the possible disruptions of biotic interactions owing to the recent invasion by T. absoluta in European tomato crops, (ii) to identify local natural enemies attacking T. absoluta, (iii) to evaluate their effectiveness against T. absoluta when integrated into the agro-ecosystem. We showed that new interactions occurred after the arrival of T. absoluta, mainly apparent competition between whiteflies and T. absoluta, in presence of the omnivorous and generalist predator M. pygmaeus. We recorded possible new biocontrol agents and focused first on Trichogramma parasitoids, as Trichogramma achaeae was promptly commercialized against T. absoluta in France. Laboratory and field experiments failed to detect promising Trichogramma strains. In addition, intraguild predation of M. pygmaeus on parasitoid juveniles i.e. parasitized eggs, was observed and we demonstrated that T. absoluta was not a suitable host for Trichogramma parasitoids. Therefore, further studies switched on parasitoids of larval stages of T. absoluta. We demonstrated the importance of Stenomesius japonicus (Eulophidae) as a possible biological control agent against T. absoluta. The parasitoid was able to reproduce on T. absoluta over several generations under laboratory and greenhouse conditions. Despite negative interactions between the predator and the larval parasitoid, further greenhouse experiments demonstrated that two competitors can coexist for several months. Moreover, the presence of an alternative prey for the omnivorous predator (whitefly) in the agro-ecosystem did not prompt larval parasitoid exclusion, and the parasitoid remained in the crop even in the presence of other prey for the predator

Full textThis research explores the interrelations between war and the destruction of the environment through the entanglements of the soviet policy of chemical struggle against agricultural pest and the preparation for war. The first chapter is organized around the institutionalization of applied entomology and the telescoping of war and « natural disasters » until the early 1920s. The second chapter focuses on the collaborations between military, industrial chemists and entomologists for the transfer of technologies to agriculture and the policy of the establishment of the double standard policy of the German war economy. The introduction of war gas and plane dusting in agriculture is supported by the military sector organizing the promotion of a new « aerochimical » weapon. The third chapter focuses on the regions of the South East in the 1920s where intertwined human and nonhuman risks cross-fertilized and where warlike modes of struggle against pest are forged. The fourth chapter relates to the creation of a hyper centralized and planned system of struggle against pest stimulated by the mass proliferations of the Great Turn and to the promotion of “brute force technologies” for pest control during the first Five Year Plan. The fifth chapter focuses on the interdependencies of the internal colonization of the USSR, the struggle against pest and dekulakization during the crisis of the collectivization, the famine and preparation for war. In 1933, the intertwined destruction of life reaches an apogee. New organizational practices emerge during this period for the whole decade

Full textIn the context of reducing pesticide use, the potential role of some arthropod groups as pest natural enemies provides them an ecological and economic interest. In particular, ground beetles and spiders are generalist predators likely to be effective biocontrol agents. Previous studies have shown that the structure and composition of their communities, as well as the effectiveness of biological control, are influenced by landscape heterogeneity, and in particular by the presence of semi-natural habitats. However, the role of the crop mosaic, which can be highly heterogeneous in space and time, have been little considered. The main objective of our study was to determine the influences of spatial and temporal heterogeneity of agricultural landscapes on generalist natural enemies and the potential for biological pest control. We sampled carabid and spider communities in winter cereal fields, and estimated biological control potential using sentinel aphids glued on predation cards. We characterized the spatial heterogeneity of the landscapes around each cereal field by 1) the amount of wooded habitats and the length of the hedgerow network, 2) the average size of the agricultural fields, and 3) crop diversity. We also proposed four new metrics that synthesize different aspects of the multi-year temporal heterogeneity of cropped areas. Our results show that in spring, landscapes characterized by small fields, and therefore by a high density of non-cropped field margins, promote spiders abundance in cereal fields. In early summer, landscapes with small fields also promote aphid predation rates and the abundance of carabid spring breeders, which overwinter as adults in semi-natural habitats. Crop diversity promotes the abundance of carabids overwintering in soils of arable fields and breeding in autumn. Our results also show that the temporal heterogeneity of the crop mosaic - characterized among other things by the changes in crop diversity over a five year period - benefits some carabid species commonly found in agricultural landscapes (such as Poecilus cupreus and Pterostichus melanarius) which are likely to play an important role as pest natural enemies. These results highlight the complementary role of the crop mosaic and the non-cropped field borders for generalist natural enemies, and show the importance of taking into account the spatial and temporal heterogeneity of the cultivated area in further ecological studies on biodiversity in agricultural landscapes. In the context of reducing pesticide use, our results suggest that landscapes with 1) a high crop diversity that change over time, and 2) small fields that promote the interspersion between crops and semi-natural habitats, are likely to promote generalist natural enemies and biological pest control

Full textIntroduced rats (Rattus spp.) are one of the major invasive species threatening native biodiversity on islands worldwide. Twospecies, the black rat (R. rattus) and the Pacifie rat (R. exulans) are sympatric in New Caledonian rainforests, where questionsasto the feasibility and the utility of their control (i.e. local limitation of their abundance) for the conservation of nativebiodiversity remain unanswered. ln response to the lack of a conceptual framework for control projects, we fi rst conducted areview of invasive rat control operations in island natural areas worldwide. Then we sought to characterize and understand thepopulation dynamics of these two sympa tric rat species and the ir interactions with native biodiversity in the rainforest of MontPanié mountain. Lethaltrapping operations and capture-mark-recapture showed that black rats were more abundant thanPacifie rats. Diet analysis revealed that the two species consume both shared and unshared prey likely resulting in astrengthening and a broadening oftheir impacts on native biodiversity, relative to the impact that each species would haveal one. Rats consume a large quantity of fruits and seeds, invertebrates, and Squamates. However, birds, which often justify theimplementation of rat management projects, do not appear here to be one of the ir preferred prey, either as adults or throughnest predation. A potential positive rat impact on seed dispersal was a Iso highlighted through a comparison of seedgermination after seeds had passed through rat versus native frugivore digestive tracts. Finally, we propose lethal trappingstrategies to efficiently control invasive rat populations. A better understanding ofboth rat impacts in sympatric situations,and the link between rat density and the intensity of their effects on biodiversity would allow optimizing rat control strategieswhen eradication is not feas ible

It is based on the following principle: the interests of an animal, not to suffer and to live a fulfilling life, is as important as the equivalent interests of a human being. Both of them want the same: to live their life. The animal liberation struggle wants to be seen as a progressist struggle, as a political change in our relationships to other animais and to ourselves.
