美国采购需求：中国杀虫剂，中国杀虫剂清单，杀菌剂，杀虫剂，杀蝗虫，蝗虫微孢子虫

I'm looking to purchase your Nosema locustae product for effective grasshopper control. Can you let me know if you offer a powdered or freeze-dried formulation that is stable at room temperature and doesn't require refrigeration during shipping? Additionally, do you currently ship directly to the U.S. or have a distributor here? I'm eager to move forward, so any info you can provide would be greatly appreciated.
