在不同的温度(20,25,30,35,40℃)和暴露时间(6,12,18,24,30,36,48,54小时)内,在真空庄热器条件下(34.6～44,0KPa),对CO _2:防治各生活期的谷蠹、米象、据谷盗和印度谷螟效果进行了试验.在20℃处理54小时;25℃,30小时;30℃,24小时,35℃,18小时;40℃,12小时的条件下能阻止这些害虫在任一发育期的存活.试验证明,成虫特别敏感,在20℃,24小时或30℃以上,6小时的条件下可以达到100%的死亡率.谷蠹的卵,印度谷螟的成熟幼虫及蛹在20℃时的耐受力特强,分别需暴露54小时和48小时才能阻止其成活. At different temperatures (20,25,30,35,40 ℃) and exposure time (6,12,18,24,30,36,48,54 hours), in the vacuum Zhuang conditions (34.6 ~ 44 , 0 kPa) were used to test CO_2: rice borer and rice elephant in each stage of life, treated at 20 ° C for 54 hours, 25 ° C for 30 hours, 30 ° C for 24 hours, 35 ℃, 18 hours, 40 ℃, 12 hours under the conditions to prevent the survival of these pests in any development period.Experiments have shown that adults are particularly sensitive at 20 ℃, 24 hours or 30 ℃, 6 hours of conditions can be achieved 100% mortality.Growth eggs, mature larvae and pupae of the Indian rice stem borer at 20 ℃ tolerance exceptionally strong, were exposed to 54 hours and 48 hours, respectively, to prevent its survival.
