Methods: Contact method with thin-layer of the products. Two insecticides were tested. The products were painted on test boards with the dose of 15mg a.I./m2 and the boards were stored at room temperature for 24 hrs, 0.5 year, 1 year, 1.5 year and 2 years. Two strains of sensitive cockroach ( Blattella germanica and Periplaneta americana ) were used in the efficacy tests and stability tests.

药膜接触法，2种药笔按国家标准分别进行药效测定，即在实验室采用相同的药膜板，2种药笔分别按15mg/m2均匀地涂抹于药膜板上，在室内常温自然存放24h、半年、1年、1年半和2年，每一个时段用两种敏感品系试虫分别进行药效和持效测定。

Its activity was specific and was affected by pH, reaching the peak in weak acidic condition. It obviously inhibits amylases from D. melanogaster, Solenopsis invicta, Odontotermes formosanus, Periplaneta Americana Linnaeus, and Alphitobius sp. In addiction, the study points out Phaseolus vulgaris, Phaseolus coccineus L. and Glycine max, which have significant inhibition toward pancreatic amylase.

经测试发现此抑制剂在85℃时仍具备抑制果蝇淀粉酶之活性，为一热安定性蛋白质，其抑制作用受pH 值影响很大，在偏酸性环境下的效果最好，且其抑制作用具特性，可明显抑制果蝇、入侵红火蚁、白蚁、蟑螂及面包虫等昆虫的淀粉酶活性。

Whole-cellpatch-clamp technology demonstrated that VDPG (1g/L) had notsignificant effects on the delayed-rectified K~+ current, TTX-sensitive Na~+ current and high-voltage-activated Ca~(2+) current of rat dorsalroot ganglion cells. The fast transiet K~+ current of cottonbollworm dorsal DUM cells, the fast transiet K~+ current, Na~+ current andhigh-voltage-activated Ca~(2+) current of Periplaneta Americana dorsalunpaired median cells were also not significantly affected byVDPG at the same concentration. However, VDPG had significant effecton the fast transiet K~+ current of Pieris rapae. The VES had not significanteffects on the high-voltage-activated and low-voltage-activated Ca~(2+)current of rat DRG cells.

膜片钳电生理实验显示1g／L毒囊粗毒对蜚蠊DUM神经元的快瞬时钾电流、钠电流、高电压激活的钙电流，对棉铃虫快瞬时钾电流和大鼠DRG细胞延迟整流钾电流、TTX-S型钠电流、高电压激活的钙电流均无明显作用，却对菜青虫快瞬时钾电流有明显作用；电刺激粗毒对大鼠DRG细胞低电压和高电压激活的钙通道无明显作用。

Bioinformatic analysis of this gene revealed that this protein belonged to the member of family 35 of glycoside hydrolyase superfamily 42, and had a closer genetic relationship with Arabidopsis thaliana, but farther with Persea americana and Picea sitchensis.

生物信息学分析结果表明，该番木瓜β-GAL属于糖苷水解酶超级家族42中家族35的成员，在进化过程中与拟南芥的亲缘关系较近，与鳄梨和北美云杉则较远。

The nucleotide sequences of the PAP gene and PAPⅡ gene in the root of Phytolacca americana were determined by reverse transcription polymerase chain reaction and PCR. The gene comprises 942bp and 933bp respectively, encoding 313 amino acids and 310 amino acids. When PAP gene and PAPⅡ gene sequences in the root were compared with those in the spring leaves and summer ones, the highest similarity 100% and 99. 8% were observed respectively. They both had one open reading frame . Analysis of the two sequences showed, in fact, they belonged to one species.

以美洲商陆根为材料，提取其总RNA、反转录，用一对PAP基因的特异性引物和一对PAPⅡ的特异性引物，分别对反转录产物进行PCR扩增，将扩增的目的片段进行序列分析，结果扩增出来的PAP基因与已经报道的序列完全相同，扩增出来的PAPⅡ基因与已经报道的序列同源性也在99.8％，而且它们都各自编码一个开放阅读框架，可以说美洲商陆根中肯定存在PAP和PAPⅡ基因，并已经转录。
