| 中文摘要: |
| 为研究白蚁饵料成型工艺，比较了9种胶黏剂对白蚁纤维素饵料成型效果、耐水性能以及对白蚁取食的影响。结果表明：20%、40%剂量糊精；50%、100%剂量三聚氰胺甲醛树脂，10%、20%、40%田菁胶、卡拉胶、壳聚糖、明胶；10%、50%、100%聚乙烯醇、硅酸钠对微晶纤维素的成型效果较好，经上述剂量胶黏剂处理后，纤维素饵块的邵氏硬度（HD）极显著高于对照。耐水性能试验至第30天时，50%聚乙烯醇、100%聚乙烯醇、100%三聚氰胺甲醛树脂处理的纤维素饵块的溃散程度指数分别为1.33、1.00、2.00，其余饵块的溃散程度指数均达3级。生测结果显示，在7 d的室内强迫取食试验中，白蚁对50%聚乙烯醇、100%聚乙烯醇、100%三聚氰胺甲醛树脂处理的块状纤维素饵料的取食率均极显著低于对照，说明饵块中添加的上述胶黏剂对白蚁的取食具有一定的影响。综上，50%聚乙烯醇、100%聚乙烯醇、100%三聚氰胺甲醛树脂适用于白蚁纤维素饵料成型，但若想获得白蚁喜食的饵块仍需对配方做进一步的优化。 |

| Effects of 9 adhesives on the shaping, water resistance of termite cellulose bait and feeding of termites were compared in order to explore the shaping technology of termite bait. The results showed that 20% or 40% of dextrin, 50% or 100% of melamine formaldehyde resin, 10% or 20% and 40% of sesbania gum, carrageenan, chitosan, gelatin; 10% or 50% and 100% of polyvinyl alcohol and sodium silicate had better performance on shaping effect of microcrystalline cellulose. The shore hardness of cellulose block bait was significantly higher than the control after treatment with these adhesives. The results of water resistance test showed that the grade index of collapse of the cellulose block baits which were treated with 50% polyvinyl alcohol, 100% polyvinyl alcohol and 100% melamine formaldehyde resin were 1.33, 1.00 and 2.00 after 30 d, respectively, but other block baits all reached grade index 3. However, the results of bioassay showed that the consumption rate of cellulose block bait was significantly lower than the control after treatment with 50% or 100% polyvinyl alcohol and 100% melamine formaldehyde resin in 7 d s no choice feeding test under laboratory conditions. It indicated that these adhesives which were added into the block bait had a certain influence on the feeding of termites. In summary, 50% or 100% polyvinyl alcohol and 100% melamine formaldehyde resin are suitable for the shaping technology of termite cellulose bait, but further optimization of the formula of block bait is needed to obtain a kind of termite liked block bait. |
