Abstract:

To investigate the control effects of different types of traps on Grapholitha molesta in the field, this study compared the control effects of four types of traps on G. molesta in cherry orchards. A field experiment was conducted in a cherry orchard in Baoding using sex pheromones as attractants. The results showed that the triangular trap had the best trapping efficacy, capturing 394 moths in two weeks with 10 traps. The boat-shaped trap ranked second, capturing 207 moths, while the two general bucket-shaped traps captured 90 moths (with yellow lids) and 56 moths (with green lids), respectively. Through an investigation of shoot-breaking rates, it was found that all four traps effectively mitigated the shoot-breaking phenomenon caused by G. molesta. The CK group (control group) experienced a 12.46% increase in shoot-breaking rate within one week, whereas the triangular trap showed the slowest increase at only 2.38%, followed by the bucket-shaped (green) trap at 2.99%, the boat-shaped trap at 4.01%, and the bucket-shaped (yellow) trap had the worst effect at 4.92%. Additionally, by comparing the trapping of other insects by the four traps, it was found that the triangular trap and the bucket-shaped (green) trap captured 100% harmful insects, and the bucket-shaped (yellow) trap and boat-shaped trap had a certain degree of false capture of beneficial insects. The research results indicate that the triangular trap has the best trapping efficacy against G. molesta and can be promoted for application in production.
