Abstract:

  [Objectives]  To provide a theoretical basis for breeding cotton varieties resistant to Apolygus lucorum (Meyer-Dür) and improve the IPM of this pest. [Methods]  With pure air as the blank control, we explored the relative preference of experienced or inexperienced A. lucorum for the odors of two cotton varieties (lines): Ling-29 (resistant) vs. Kelin08-23 (susceptible), 07 Shengshi6 (resistant) vs. Kangbingdanzhu-1 (susceptible) in a “Y” tube olfactometer.    [Results]  Both experienced and inexperienced A. lucorum significantly preferred the susceptible cotton varieties Kelin08-23 and Kangbingdanzhu-1 to the resistant varieties, Ling-29 and 07 Shengshi. Furthermore, A. lucorum significantly preferred susceptible cotton plants that had been previously damaged by A. lucorum. [Conclusion]  Generally speaking, A. lucorum significantly preferred intact susceptible cotton varieties to intact resistant cotton varieties. But A. lucorum insignificantly preferred induced susceptible cotton varieties to induced resistant cotton varieties.
