Several protection methods are recommended to control the development of whiteflies on zucchini in France:
- treat plants before uprooting in the presence of high pest populations;
- check the sanitary quality of the plants before and during their introduction into the shelter;
- produce the plants in an shelter insect-proof ;
- install canvases insect-proof at shelter openings;
- weed the greenhouse and its surroundings;
- detect the first pests thanks to the yellow sticky panels placed above the crop as soon as the plants are introduced;
- use auxiliaries such as the insects Encarsia formosa, Eretmocerus eremicus (these two insects are especially effective on Trialeurodes vaporariorum, Eretmocerus mundus - mainly effective on Bemisia tabaci ) and Macrolophus caliginosus and the fungi Paecilomyces fumosoroseus and Verticillium lecanii (note that its effectiveness may vary from one strain to another);
- reason the chemical protection (r) (e-phy whiteflies, Trialeurodes vaporariorum and Bemisia tabaci ) *, in particular if you use auxiliaries.
