ABSTRACT

Ticks are ubiquitous in nature and have considerable medical and veterinary importance. They act as vectors for a diverse array of pathogens affecting animals and humans. Rhipicephalus sanguineus is the most prevalent species infesting the dogs in Tamil Nadu. Control of this three-host tick mainly depends on the use of acaricides, with attendant problems of development of acaricidal resistance in ticks and possibility of drug residues. In the current study, pheromones were evaluated as an alternative substance for control of the dog tick. Optimal concentration of attractant sex pheromone (ASP), assembly pheromone (AP), and combination of both ASP and AP were encapsulated using calcium alginate beads for sustained release of pheromones. Bamboo sticky traps were designed as a platform to hold these pheromone encapsulated beads. Field trials were conducted using these pheromone lures as bait in the bamboo trap. Field trials revealed that AP encapsulated calcium alginate beads lured the maximum number of different stages of dog ticks. Thus, a bamboo trap with AP encapsulated calcium alginate beads can be used in integrated pest management along with other routine practices for control of dog tick in kennels. Statistical analysis by chi-square test revealed that there was a highly significant (p < 0.01) difference in the level of attraction between engorged and questing stages of ticks to the pheromones in the trap.

摘要

cks虫在自然界无处不在，在医学和兽医方面具有相当大的重要性。它们充当影响动物和人类的多种病原体的媒介。红头蛇是泰米尔纳德邦最流行的犬种。对这种三宿主tick的控制主要取决于杀螨剂的使用，伴随出现problems中杀螨抗药性发展和药物残留可能性的问题。在当前的研究中，信息素被评估为控制狗虱的替代物质。使用藻酸钙珠粒封装引诱性信息素（ASP），装配信息素（AP）以及ASP和AP的组合的最佳浓度，以持续释放信息素。竹粘陷阱被设计为容纳这些信息素封装的珠子的平台。使用这些信息素诱饵作为诱饵在竹陷阱中进行了田间试验。现场试验表明，AP封装的海藻酸钙珠吸引了狗虱不同阶段的最大数量。因此，带有AP封装的海藻酸钙珠的竹陷阱可以与其他常规方法一起用于综合害虫管理，以控制狗窝中的狗虱。卡方检验的统计分析表明，充实和探索阶段的to对诱捕剂中信息素的吸引水平之间存在极显着（p <0.01）的差异。
