Used field surveys, data collection methods, the following conclusions:(1)Robinia honey changes have shown a fundamental parabolic, hill slope of south, north, southeast, southwest and plains being shown no differences, but hill slope of north being found significant differences from any others, the highest output in the hill slope of south reach 6.8 kg/ box, the lowest average 2.7 kg / box. The maximum output for minimum yield is two-folded.
(2)Main nursing techniques included strictly regulating temperature and humidity of breeding box during breeding period, proper ventilation, sunshine, good hygiene and tender care from nursing staff. (3) Colony behaviour taming began at 20 days old. Taining of returning -to-colony began at 145 days old, and it was successfully returned to the cage-raised colony and admitted by Other golden monkeys.
Planting mulberry sapling in diseased soil inside a box with glass in both sides, it's observed that mycelia of Helicobasidium mompa Tanaka grew slowly and the healthy roots wouldn't be infected even after contacting, whereas most rhizomorph can infect healthy roots. When the mycelia and the mulberry roots has established parasitism relations, the mycelia spred quickly in the mulberry roots.
2. The Cloned BmandHSC70-4 and BmHSC70-4 5'FR, and Characterestic and functional analysis of BmandHSC70-4 and BmHSC70-4 promotersThe Cloned BmandHSC70-4 and BmHSC70-4 5'FR, consisting of the partial first exon, the central promoter region and 5'-upstream region, harbor six GATAs, two CAATs and two HSFs, but no TATA and GC box.
The BmUCE2I gene contains 4 exons and 3 introns and the putative promoter was between-219 bp～-268 bp of 5′upstream sequence relative to translation start site. The BmUCE2I promoter contains no TATA box,but potential binding sites for the transcription factors were detected in both forward and reverse orientation : CF2-Ⅱ、FTZ、DFD、BRCZ2、DL、STAT、PRD-HD.
Yuhang city began to introduce and rear a new silkworm variety for Summer-autumn Rearing, Fangcao ×Chen·Xing in 1996. It demonstrated that the new var1ety pos-sess strong reslstance to fluoride and other disadvantageous factors,and the yield of cocoonraised more than 7% per box,income enhanced RMB 20-45 yuan per box by pot and con-trast experiment,and sampling survey.
Results indicated that constant temperature of(29±1)℃, relative humility from 50% to 70% and the rearing density of 300 per box were appropriate for mass production of G. mellonella . Light had little effect on development of G.
