- Abstract
In order to explore the trapping effect of trap plants on Frankliniella occidentalis on protected cultivated strawberries, the Y⁃shaped olfactometer was used to measure the trapping effect of 7 plants (jasmine, gardenia, verbena, night sky petunias, snap bean, red rose and eggplant) on Frankliniella occidentalis. The trapping effects of different planting orientations (east, west, south, north and centre) planting modes (spot and sheet planting), and planting densities (ratios of 1: 4, 1: 7 and 1: 11 to strawberry seedlings, respectively) of trap plant on Frankliniella occidentalis were studied in the field. The results showed that the preference order of Frankliniella occidentalis for 7 types of trap plants was jasmine>gardenia>verbena>night sky petunias>snap bean>red rose>eggplant. The selective experiment results of Frankliniella occidentalis between different plants and strawberry showed that jasmine was the most attractive plant for Frankliniella occidentalis, and it was the most suitable for conducting subsequent field trapping effect experiments intercropping with strawberry. In the field experiment, the jasmine planted in the south direction was the earliest to attract Frankliniella occidentalis, and the trap number was the highest throughout the entire investigation period; The number of Frankliniella occidentalis trapped by jasmine planted in four directions of east, west, south, and north first increased and then slightly decreased; The number of Frankliniella occidentalis trapped by jasmine planted in the centre direction continued to increase, but was less than the number of Frankliniella occidentalis trapped in the south direction. During the entire survey period, the number of Frankliniella occidentalis trapped by jasmine in the spot planting area was significantly higher than that in the sheet planting area; On April 15, jasmine in the spot planting area first trapped Frankliniella occidentalis; On May 15, the number of Frankliniella occidentalis trapped by jasmine in both point and sheet planting areas reached the highest. The number of Frankliniella occidentalis on strawberry intercropping with jasmine was significantly lower than that of strawberry monoculture (CK), and the best trapping effect was achieved when the intercropping ratio of jasmine to strawberry was 1: 7; On May 25, June 5 and June 15, the number of Frankliniella occidentalis trapped under this proportion treatment decreased by 343 individuals per plant, 295 individuals per plant and 300 individuals per plant, respectively, compared with CK.
