Dead neonatal mice are currently used as bait for delivery of toxin to invasive brown treesnakes (Boiga irregularis) on Guam; once deployed in the field the mice are highly attractive to the snakes but only for about four days. An artificial bait containing a mixture of fats mimicking those in skin of the mice is also highly attractive to the snakes and remains attractive 2–3 times longer. The artificial bait, however, costs more than the mice, and is more difficult to attach to the capsules of a novel aerial bait delivery system. This paper describes a reformulation of the bait which reduced the ingredient cost to 11% of its former value, without compromising its attractiveness to free-ranging snakes. Three lipid formulations using different source materials to produce the same fatty acid profile target were tested along with two levels of pork fat to yield six test formulations. No differences in bait disappearance were noted in field testing of the baits, indicating that decisions regarding bait formulation could be made on the basis of cost without sacrificing efficacy. Separately, testing of 17 commercially available adhesives identified five for field testing. Among these, two demonstrated strong, weather-resistant bonds between the oily surface of the artificial baits and the bait capsules as evidenced by only 13.4% and 4.5% of baits falling off suspended capsules. Importantly, neither of these adhesives impacted bait removal by snakes in field trials in comparison to baits with no adhesive.. The results represent an advance in technology development for landscape-scale suppression of brown treesnake populations.

死亡的新生小鼠目前被用作诱饵，将毒素传递给侵入性棕色树蛇（不规则Boiga））在关岛；一旦部署到野外，老鼠对蛇非常有吸引力，但只持续了四天。含有模仿老鼠皮肤脂肪的混合物的人造诱饵对蛇也极具吸引力，并且保持诱饵的时间长2至3倍。然而，人工诱饵的成本比小鼠高，并且更难以附着到新型空中诱饵输送系统的胶囊上。本文介绍了一种重新设计的诱饵，该诱饵将原料成本降低到其原价的11％，同时又不损害其对散养蛇的吸引力。测试了三种使用不同原料产生相同脂肪酸谱目标的脂质配方，以及两种水平的猪肉脂肪，得出了六种测试配方。在诱饵的现场测试中没有发现诱饵消失的差异，表明有关诱饵配方的决定可以在不牺牲功效的前提下根据成本做出。另外，对17种市售粘合剂的测试确定了5种用于现场测试。其中，两个表明在人造诱饵的油性表面和诱饵胶囊之间具有牢固的耐候性结合，只有从悬吊胶囊掉落的诱饵中分别有13.4％和4.5％证明了这一点。重要的是，与没有粘合剂的诱饵相比，在田间试验中，这两种粘合剂都不会对蛇的诱饵去除产生影响。结果表明，在抑制棕树蛇种群的景观规模技术发展方面取得了进展。对17种市售粘合剂的测试确定了其中5种用于现场测试。其中，两个表明在人造诱饵的油性表面和诱饵胶囊之间具有牢固的耐候性结合，只有从悬吊胶囊掉落的诱饵中分别有13.4％和4.5％证明了这一点。重要的是，与没有粘合剂的诱饵相比，在田间试验中，这两种粘合剂都不会对蛇的诱饵去除产生影响。结果表明，在抑制棕树蛇种群的景观规模技术发展方面取得了进展。对17种市售粘合剂的测试确定了其中5种用于现场测试。其中，两个表明在人造诱饵的油性表面和诱饵胶囊之间具有牢固的耐候性结合，只有从悬吊胶囊掉落的诱饵中分别有13.4％和4.5％证明了这一点。重要的是，与没有粘合剂的诱饵相比，在田间试验中，这两种粘合剂都不会对蛇的诱饵去除产生影响。结果表明，在抑制棕树蛇种群的景观规模技术发展方面取得了进展。
