Intérêts du phénotypage de la personnalité pour améliorer la lutte biologique : cas d’étude chez l’auxiliaire Trichogramma evanescens

2021

One promising approach to improve the use of biological control agents (BCA) consists in the exploitation of intraspecific variation on traits related to mass-rearing or field performance. Consistent inter-individual variations in behaviour (known as personality) have never been considered in biological control (BC) while they have proved to be heritable and correlated to phenotypic traits possibly related to fitness in rearing or field conditions. The aim of this PhD thesis was (i) to develop an experimental design to measure personality traits in a the egg-parasitoid Trichogramma evanescens, and (ii) to evaluate the feasibility and interest of phenotyping personality traits to set and imp…
