Popis: Tomatoes can be screened for resistance to Drosophila by using a slit-fruit technique, or by trapping adult flies in jars containing sections of fruit of different varieties. These techniques can be used on a turntable to eliminate light effects, or by randomization in a greenhouse or an enclosed room with uniform light. Significant differences were found, both when Drosophila could choose between varieties and when they were restricted to cages containing fruit of only one variety. Due to the large amount of variation encountered when screening tomatoes for Drosophila resistance, large numbers of replications are necessary. The variation can be partially accounted for by differences in fruit maturity and differences between plants of a variety or line.
