2.3 two kinds of fumigant smoked killing effect evaluations to semanotus bifasciatus respectively
Result illustrates:
1) when the dosage of carbonyl sulfide is 44.73g/m3When, the dead probit value of semanotus bifasciatus is 5, i.e. dead Rate reaches 50%, say, that lethal concentration of 50 LC to semanotus bifasciatus for the carbonyl sulfide50=44.73g/m3。
2) when the dosage of carbonyl sulfide is 193.63g/m3When, the dead probit value of semanotus bifasciatus is 9, i.e. dead Rate reaches 50%, say, that absolute lethal concentration LC to semanotus bifasciatus for the carbonyl sulfide100=193.63g/m3。
3) when the dosage of vikane is 38.99g/m3When, the dead probit value of semanotus bifasciatus is 5, i.e. the death rate Reach 50%, say, that lethal concentration of 50 LC to semanotus bifasciatus for the carbonyl sulfide50=38.99g/m3。
4) when the dosage of vikane is 140.77g/m3When, the dead probit value of semanotus bifasciatus is 9, i.e. the death rate Reach 50%, say, that absolute lethal concentration LC to semanotus bifasciatus for the carbonyl sulfide100=140.77g/m3。
Therefore, learn that the lethal concentration of 50 of two kinds of medicaments is more or less the same by calculating, all at 35～45g/m3Between；And In actual mechanical process (Tables 1 and 2) also it is seen that, the lethal concentration of 50 of two kinds of medicaments is more or less the same equally, all exists equally 35～45g/m3Between.But, by the comparison of the absolute lethal concentration numerical value of two kinds of medicaments, it appeared that the drug effect of vikane Better.Further, since cypress can adsorb fraction of fumigant, so the data of the data that draw of theory and practical operation are slightly There is deviation.
