Larval survival on wheat plants carrying resistance genes to hessian fly (diptera: cecidomyiidae)‎ in Morocco

الملخص EN

A growth chamber test was conducted to determine which of the wheat genes that condition resistance to Hessian fly, Mayetiola destructor (Say) in Morocco, allow for larval survival on resistant plants.

ne results showed that H7H8 genes allowed the highest larval survival (34.8%) and that H5, HI l, HI 3, H22 and H23 genes allowed for little or no larval survival.

Theses larvae, which were plants, has little negative effect on plant growth, Resistance genes that allow avirulent larvae to survive on resistant plants should be ce selection for biotype development.
