谷实夜蛾和烟芽夜蛾是美国南部和中南部主要害虫。在保铃棉上烟芽夜蛾可得到控制,但谷实夜蛾仍需药剂防治。研究表明,当保铃棉的100%白花被谷实夜蛾侵染1～4周或50%白花被侵染2～4周,成熟明显地推迟;子棉产量随侵染白花数量的增加而降低,二者呈明显的负相关。该研究结果为确定
Helicoverpa zea and tobacco budworm are major pests in the southern and southern Central United States. The bollworm can be controlled on cotton bollworm, but it is still needed to control the drug. The results showed that when the 100% cotton bollworm was infected with Helicoverpa armigera for 1 ~ 4 weeks or 50% white flowers were infected for 2 ~ 4 weeks, the maturity was obviously delayed. The yield of cotton seedlings increased with the increase of the number of infected white flowers Lower, the two showed a significant negative correlation. The results of this study were confirmed
