Preliminary Study on Shelf Life of Artificial Feed of Chilo suppressalis
|
摘要
In order to preliminarily explore the preservation effect of ordinary refrigerator( 4℃) on artificial diet of Chilo suppressalis,the effects of artificial feed preserved at refrigerator for different time on percentage of pupation and pupa weight of C. suppressalis were investigated to understand the impact of long-term storage of artificial feed on the growth and development of C. suppressalis. The results showed that the percentage of pupation of C. suppressalis fed with artificial diet that had been stored in refrigerator for 40 d( T40) was highest( 67. 1%),followed by CK( 1 d,63. 5%),and the percentage of pupation of C. suppressalis fed with artificial diet that had been stored in refrigerator for10 d( T10) was 61. 9%. No significant difference was found in percentage of pupation among the treatment groups( P > 0. 05). The female pupa weight of the short-term preservation treatment group( 71. 9 mg) was significantly larger than that of the long-term preservation treatment group( 66. 1 mg)( P < 0. 05),and was insignificantly different from that of CK( P > 0. 05). The male pupa weight of the short-term preservation treatment group( 51. 2 mg) was significantly larger than that of CK( 47. 7 mg)( P < 0. 05),and the male pupa weight of the long-term preservation treatment group was slightly larger than that of CK( P > 0. 05). In conclusion,the artificial diet of C. suppressalis can be stored for at least 40 d in refrigerator( 4℃).
