Protection methods

Several protection methods are recommended to control the development of aphids on zucchini in France:

• 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 Aphelinus abdominalis, Aphidius colemani, Aphidius ervi, Aphidoletes aphidimyza and  Macrolophus caliginosus (the latter is of secondary efficacy) and the fungus Verticillium lecanii (note that its efficacy may vary from one strain to another );
• consider chemical protection (r) ( e-phy ) *, in particular if you use auxiliaries.

(r): resistance to insecticides or acaricides is known in these pests.
