ABSTRACT
In order to describe the developmental biology of the tick Argas neghmei Kohls & Hoogstraal under laboratory conditions, 40 females and 40 males were collected from chicken coops located in Calama (II Region, Chile). They were fed on chickens and maintained under two laboratory conditions one group at 30 ± 5 ºC and 35 ± 5 percent RH and another at 27 ± 5 ºC and 80 ± 5 percent RH, both at 12 12 h LD photoperiod. The ticks were observed daily to determine larval feeding periods, preoviposition, oviposition, egg incubation as well as the frequency of egg laying, number of eggs laid, and percentage of larval hatching. Females did not lay eggs at 80 ± 5 percent RH, and data on the biology of this tick was obtained only at 35 ± 5 percent RH. The life cycle of A. neghmei lasted an average of 269 days. Feeding period of each nymphal stage as well as of adult females between oviposition events lasted less than a day. Females laid on average 1.8 egg batches and egg-laying period lasted on average 14 days, during which about 96 eggs were laid per female.
