Evaluation De L’activité Acaricide De Quelques Biopesticides Sur L’acarien Tarsonème, Polyphagotarsonemus Latus Banks (Acari : Tarsonemidae) Infestant L’aubergine Gboma (Solanum Macrocarpon L.) Au Sud-Bénin

Potential of the predatory mite, Amblyseius swirskii to suppress the Broad Mite, Polyphagotarsonemus latus on the Gboma Eggplant, Solanum macrocarpon

In Benin, the tarsonemid mite Polyphagotarsonemus latus (Banks) (Prostigmata: Tarsonemidae) is a key pest of gboma eggplant Solanum macrocarpon (L.) (Solanales: Solanaceae), a leafy vegetable on which it causes considerable damage to the plants and substantial reduction in yield. Predatory mites in the family Phytoseiidae have been successfully used in the biological control of numerous agricul...

Dispersal of Amblyseius swirskii (Acari: Phytoseiidae) on High-Tunnel Bell Peppers in Presence or Absence of Polyphagotarsonemus latus (Acari: Tarsonemidae)

Amblyseius swirskiiAthias-Henriot (Acari: Phytoseiidae) is a predatory mite used to control thrips (Thysanoptera), whiteflies (Bemisia tabaci Genn., Hemiptera: Aleyrodidae), and broad mites (BMs) (Polyphagotarsonemus latus Banks, Acari: Tarsonemidae). Dispersal of A. swirskii, using the ornamental pepper "Explosive Ember" as a banker plant was evaluated for control of BMs in high-tunnel peppers...

Quelques mots sur l’inégalité de concentration de Azuma-Hoeffding

L’inégalité de concentration de Azuma-Hoeffding fait partie de ces beaux outils mathématiques à la fois simples et utiles. Elle mérite d’être connue par tous ceux qui s’intéressent aux probabilités. Dans cet exposé, on en donne une version due à McDiarmid, ainsi qu’une application aux mesures spectrales empiriques de matrices aléatoires, puis au problème du voyageur de commerce en optimisation ...

THESE DE DOCTORAT DE L ’ UNIVERSITE PARIS SUD - 11 Ecole

Photosystem II (PSII) uses light energy to oxidise water and reduce quinone. The water oxidation site is a Mn4Ca cluster located on the luminal side of the membrane protein complex, while the quinone reduction site is made up of two quinones (QA and QB) and a nonheme Fe located on the stromal side of the membrane protein. In this thesis I worked on both oxidation and reduction functions of the ...
