Dose-response relationship between abamectin and mortality of Panonychus ulmi (Acari: Tetranychidae)

60-65In this study, the dose-response relationship between abamectin and mortality of larval and adult forms of Panonychus ulmi (Koch) was established. Abamectin was investigated at a dilution series of 1/1, 1/1.15, 1/1.35, 1/1.6, 1/2, 1/2.55, 1/4, 1/8 and 1/16 of its field recommended concentration, in order to calculate the ECi – values. Results showed that the lowest ECi – values were observed on larvae, which showed high sensitivity to abamectin than adults. Both statistical models led to satisfactory findings and the linear model was ranked as the best model for describing the dose-response relationship. This research highlighted the importance of toxicity risk assessments to obtain a more accurate estimation of the compatibility of abamectin in the integrated pest management (IPM) programs

Séparation de composantes des signaux biomécaniques par une approche parcimonieuse

International audienceIn this communication, we are interested in processing of biomechanical signals in order to separate their active and passivecomponents. To do so, we propose a sparsity-based approach using two families of algorithms, one greedy and the other based on relaxationnamely Orthogonal Matching Pursuit (OMP) and Least Absolute Shrinkage and Selection Operator (LASSO).We use the discrete sinus transformas a dictionary to extract the active component from the ground reaction signal. The theoretical results will be validated on real biomechanicalsignals.Dans cette communication, nous nous intéressons au traitement des signaux biomécaniques dans le but de séparer leurs composantesactive et passive. Pour ce faire, nous proposons une approche basée sur la parcimonie utilisant deux familles d’algorithmes, un de type glouton etl’autre repose sur la relaxation à savoir Orthogonal Matching Pursuit (OMP) et Least Absolute Shrinkage and Selection Operator (LASSO). Nousemployons la transformée en sinus discrète comme dictionnaire afin d’extraire la composante active du signal de réaction au sol. Les résultatsthéoriques seront validés sur des signaux biomécaniques réels
