Abstract:
The sunflower moth (Lepidoptera: Pyralidae) is one of the most serious pests of sunflower heads and seeds resulting in heavy economic losses to sunflower growers. This paper reviews the current status of resistance of sunflowers to two closely related species of sunflower moth, Homoeosoma nebulellum Denis et Schiffermüller and Homoeosoma electellum Hulst. Interactions between the morphological structure and chemical composition of different sunflower varieties, and the effects of tubular florets, achene characteristics and secondary components (phytomelanin, sesquiterpene lactones, and pollen extracts) on resistance are outlined. Finally, some potentially useful traits for breeding more resistant sunflower varieties are proposed.
