BRITO, Giovani Greigh de et al. Pickleworm [Diaphania nitidalis Cramer, 1782 (Lepidoptera: Pyralidae)]preference for cucumber cultivars in greenhouse. Cienc. Rural [online]. 2004, vol.34, n.2, pp.577-579. ISSN 1678-4596.

The pickleworm (Diaphania nitidalis) is a major pest on different crops, particulary on cucumber. This species has shown a preference for determined cultivars to its feeding and oviposition habits. Thus, the aim of this study was to evaluate the occurence of D. nitidalis larvae in fruits of six cucumber cultivars in greenhouse. The cultivars Patton, Victoria, Premier, Vlaspik and Napoleon showed, respectively, 50%, 43.75%, 37.50%, 34.37% and 25.87% of bored fruits. Promising results were obtained with the cultivar Marinda, which showed only 10.37% of bored fruits.

Keywords : pickleworm; Diaphania nitidalis; plant resistant; integrated pest management.
