Abstract:		"Dermanyssus gallinae, also known as the poultry red mite (PRM), is one of widespread ectoparasite in the poultry industry worldwide, causing direct and indirect detriments to poultry as well as substantial financial losses. Novel control methods are urgently needed to improve the current acaricide-based control of D. gallinae. The control approach based on arrestment pheromone is environment-friendly but the related research is limited in PRMs. In the present study we found two compounds from the mite feces acting as arrestment pheromones of D. gallinae, which could lead to mite arrestment upon contact. One is guanine, which was also found in unfed female mites' acid-saline extract. The other is hematin. Moreover, it was found that the ferric ion of hematin played a pivotal role in stimulating the arrestment of mites. Finally, it was found the combination of guanine or/and hematin plus cypermethrin led to significantly improved mite-killing performance compared with cypermethrin, showing a promising potential of novel control method based on the arrestment pheromone"
