A new water-resistant fire ant bait (T-bait; cypermethrin 0.128%) consisting of dried distillers grains with solubles (DDGS) as a carrier was developed and evaluated against a standard commercial bait (Advion; indoxacarb 0.045%) under both laboratory and field conditions.
When applying the normal T-bait or Advion in the laboratory, 100% of Solenopsis invicta Buren worker ants were killed within 4 days. However, when the T-bait and Advion were wetted, 70.6 and 39.7% of the ants were killed respectively. Under field conditions, dry T-bait and dry Advion had almost the same efficacy against ant colonies. However, when T-bait and Advion came in contact with water, the former's ability to kill S. invicta colonies in the field was only marginally reduced, while Advion lost virtually all of its activity. In addition, DDGS was also shown to be compatible with a number of other insecticides, such as d-allethrin, permethrin and pyrethrin.
Based on its properties of remaining attractive to the fire ants when wetted, combined with its ant-killing abilities both in the laboratory and in the field, T-bait is an efficient fire ant bait, especially under moist conditions.
一种新的耐水型红火蚁毒饵（T 型毒饵；氯菊酯 0.128%）由干燥的酒糟（DDGS）作为载体研制而成，并在实验室和野外条件下对标准商业毒饵（Advion；茚虫威 0.045%）进行了评估。
在实验室中正常使用 T 型毒饵或 Advion 时，100%的红火蚁工蚁在 4 天内死亡。然而，当 T 型毒饵和 Advion 被弄湿后，分别有 70.6%和 39.7%的蚂蚁死亡。在野外条件下，干 T 型毒饵和干 Advion 对蚁群具有几乎相同的功效。然而，当 T 型毒饵和 Advion 接触到水时，前者在野外杀死红火蚁群体的能力仅略有下降，而 Advion 则几乎失去了所有活性。此外，DDGS 还与其他一些杀虫剂如 d-苎烯、氯菊酯和除虫菊酯兼容。
T 型毒饵具有遇水仍能吸引红火蚁的特性，结合其在实验室和野外的杀蚁能力，T 型毒饵是一种高效的红火蚁毒饵，尤其是在潮湿条件下。
