Abstract (english)

Beauveria bassiana is an entomopathogenic fungus widely used in biocontrol tactics over the world. Its potential has been tested on several pest species, included the Western Flower Thrips Frankliniella occidentalis Pergande. However, knowledge on B. bassiana-thrips interactions is limited. In laboratory bioassays, we exposed different developmental stages of F. occidentalis (first and second instar larvae, adults) to residual or topical applications of a B. bassiana commercial strain
(strain ATCC 74040, Naturalis®). A moderate to high mortality was noticed for first instar larvae, late second instar larvae and adults when the two routes of exposure were combined. The results stress on the importance to favor the contact of thrips with B. bassiana to obtain satisfactory control of this pests. The significant reduction in thrips survival after B. bassiana applications suggests that the latter can be included in IPM tactics.
