Full textUnderstanding of driving forces that affect diversity in herbivorous insect communities figures prominently in ecological research, and is necessary for integrated pest management, because some herbivorous insect can become crop pests. Natural enemies and environmental variables are among factors that structure herbivorous insect communities. While natural enemies regulate herbivorous insects, environmental variables affect their diversity and their spatial distribution. The main goal of this thesis was to understand effects of landscape features on diversity of herbivorous thrips communities along elevational gradients in Reunion, and to investigate effects of natural enemy diversity in biological control of pest thrips. In first study, thrips were sampled along replicated elevational gradients, and at each sampling site, landscape features and abiotic variables were estimated within buffers surrounding the site. Study has shown that the greatest diversity of thrips in Reunion is concentrated at lower elevation, although habitats situated in these localities are highly degraded. Thrips diversity was not affected by fragmentation but landscape heterogeneity and habitat amount interacted to affect positively thrips diversity.In second study, we manipulated communities composed of two pest thrips Thrips parvispinus and Frankliniella occidentalis, and two predatory mites Amblyseius swirskii and Proprioseiopis mexicanus. These communities were in cages and were established in greenhouse. Study has shown that both predators are better than one in thrips regulation. That confirms the necessity to maintain biodiversity at the upper trophic level for herbivore control. Moreover, this study revealed that despite intraguild predation, predators would have coexisted because of competition-colonization trade-off

Full textDate fruits are subject to major attacks by insect pests. Fumigation with toxic gases is the classic and effective response to insect infestation, but it is neither environmentally friendly nor compatible with organic date certification. Alternative forms of disinfestation by thermal processes are therefore considered. The present work aims to develop experimental and modelling approaches to evaluate the impact of heat transfer (convection and electromagnetic waves) on the disinfestation of dates, while limiting browning. To achieve this, a breeding population of insects (Ephestia kuehniella Zeller) was established and a database of survival rate of eggs and larvae between 46 °C and 75 °C constructed. The two kinetic models selected (first order for eggs and a Weibull distribution for larvae) accurately describe insect survival according to their thermal history. In parallel, a 2D axis-symmetric numerical model of energy transfer was designed and solved by the finite element method (Comsol). It takes into account the various parts of a date fruit (pulp, air layer and pit) and the position of an insect in the fruit. The dielectric properties of insects and date fruit were measured and used in the model in order to simulate the coupling between the energy transfer, the survival rate of larvae located in the air layer (between pulp and pit), that of eggs on the date surface, and their interactions during heating and cooling. Achieving a low survival rate of larvae is the limiting factor for disinfestation by convection, whereas in contrast, the survival rate of eggs becomes the limiting factor for treatment by electromagnetic waves. Due to their high specific surface area, the eggs do not become hot enough to die during microwave treatment (915 MHz) at an electric field . Disinfestation by microwaves is therefore only of interest if associated simultaneously or sequentially with a surface treatment using a hot fluid (air, liquid, vapour). In contrast, an intense convective transfer (with liquid) used alone may lead to unacceptable surface browning. A microwave treatment (1 290 V m-1) associated with moderate ventilation (20 W m-2 K-1) with hot air (60 °C) for 180 s achieves an insect survival rate of 0.01% while limiting surface browning. However, this combined operation is only effective if the water content of dates is homogeneous. Indeed, the dielectric loss factor of date pulp depends strongly on water content

Full textInsect nicotinic acetylcholine receptors (nAChRs) are nowadays one important target for insecticide discovery. In this work, we have determined from a multiscale molecular modeling approach (i) the structural and conformational features of nine competitive modulators of insect nAChRs, among which the seven neonicotinoids and two emerging compounds (sulfoxaflor and flupyradifurone) (ii) the interactions of the nine compounds with a 3D model of insect nAChRs, Ac-AChBP, from docking (iii) the structural fluctuations and the variation of interaction energies of the different complexes as a function of time from molecular dynamic (MD) simulations over a period of 40 ns (iv) refined structural and energetic parameters of a selection of the most relevant complexes from QM/QM’ calculations. These studies have highlighted the important flexible character of the compounds, a significant number of energetic minima (from 5 to 10) being observed on a narrow energetic range (of about 10 kJ mol-1). The docking and MD simulations have pointed out notable differences of interactions of the ligands allowing the determination of a ranking of their interaction energies with Ac-AChBP. Finally, the trends suggested by the previous molecular modeling investigations have been refined by QM/QM’ calculations, that have led to accurate structural and energetic parameters for the various key components of the binding of these important insecticides to their target

Full textNatural ecosystems are unavoidably spatially structured and the induced heterogeneity affects various processes of ecological systems. In many cases, the influence of spatial heterogeneity on population dynamics remains unclear. This thesis contributes to a better theoretical understanding of the effects of such heterogeneity on host-parasitoid interactions. In this way, three spatial approaches were developed and adapted to the aphid pest Aphis gossypii and one of its parasitoids Lysiphlebus testaceipes in a melon greenhouse. The importance of spatial structure was tested by comparing a non-spatial model with a spatially explicit model (a lattice one). Our results showed that considering space is essential to describe the spatial heterogeneous distribution of populations Observed in the field. The way in which space should be considered was tested by comparing the spatially explicit model with a new implicit approach, which describes the level of plant infestation by a continuous variable corresponding to the number of plants with a given density of pests at a given time. When the explicit model needs as many equations as plants in the greenshouse, our novel approach has only a partial differential equation. We could infer from the comparisons between the two spatial models that the predicted host-parasitoid dynamics were similar under most conditions; and the differences were due to local dispersal (considered only in the explicit model), because it could have a strong impact on population dynamics but did not change the conclusions for crop protection. The new implicit model thus generated relevant predictions with a more synthetic formalism than the common plant-by-plant model. This implicit model was used to test biological control strategies. We showed that (i) preventive releases are less efficient than curative ones, if the cost of infestation detection is not too high; (ii) strategies with several releases are always better than single releases strategies. As a conclusion, we demonstrated that the effectiveness of a biological control depends on the functional response of the parasitoids, the initial distribution of pests (that determines the infestation process) and the costs affected to each type of strategies
