摘  要:
为判断溴甲烷和硫酰氟对舞毒蛾不同虫态的杀灭效果,在25℃下,分别在经过气密性检测的熏蒸桶内投入16、20、24、32g/m3的溴甲烷和40、56、72、88g/m3的硫酰氟,熏蒸处理舞毒蛾卵、幼虫、蛹和成虫4.5h。结果表明,经过4.5h熏蒸,杀灭舞毒蛾卵、1龄幼虫、蛹和成虫的溴甲烷浓度分别为32、20、24和16g/m3,杀灭上述虫态硫酰氟浓度分别为88、56、72和40g/m3。本文结果表明,舞毒蛾卵为最耐受溴甲烷和硫酰氟熏蒸的虫态,在目前口岸实际熏蒸处理中应充分考虑熏蒸剂对舞毒蛾卵的杀灭效果。

摘  要:
In order to determine the fumigation effects of methyl bromide(MB) and sulfuryl fluoride(SF) on different development stages of the gypsy moth Lymantria dispar L.,the killing effects were tested in the laboratory at 25 ℃ and 16,20,24 and 32 g/m3 of MB,and 40,56,72 and 88 g/m3 of SF,respectively,for 4.5 h.The results showed that the adults,larvae,pupae and eggs could be completely killed after treated with 16,20,24 and 32 g/m3 of MB and 40,56,72 and 88 g/m3 of SF,respectively,at 25 ℃ for 4.5 h.These results showed that the egg was the most tolerant stage against MB and SF,which should be taken into consideration in port fumigation treatments.
