Abstract
Oulenziella bakeri Hughes is a promising alternative prey for mass rearing of predatory mites. However, little is known regarding the effects of different temperatures on the population growth of O. bakeri. In the present study, the developmental duration, survival rate, longevity, fecundity, and sex ratio of O. bakeri were observed under laboratory conditions at 16°C, 20°C, 24°C, 28°C, and 32°C. The developmental duration and whole generation time of O. bakeri shortened with increasing temperature, except for the protonymphal duration, which was the shortest at 24°C. The maximum fecundity of O. bakeri was recorded at 28°C (176.73 eggs/female) but did not significantly differ from that at 24°C (173.80 eggs/female). The sex ratio for the progeny of O. bakeri was female-biased, and showed no significant difference among 16°C, 20°C, and 24°C, but a significant decrease as the temperature further increased. Life table analysis indicated that the net reproductive rate of O. bakeri was highest at 28°C, with a value of 140.37. Furthermore, the intrinsic rate of increase (rm) of O. bakeri ranged from 0.12 to 0.38, and increased with the temperature. Our findings suggested that temperatures of 24°C and 28°C were most suitable among the tested temperatures for rearing O. bakeri.
期刊介绍:
Systematic and Applied Acarology (SAA) is an international journal of the Systematic and Applied Acarology Society (SAAS). The journal is intended as a publication outlet for all acarologists in the world.
There is no page charge for publishing in SAA. If the authors have funds to publish, they can pay US$20 per page to enable their papers published for open access.
SAA publishes papers reporting results of original research on any aspects of mites and ticks. Due to the recent increase in submissions, SAA editors will be more selective in manuscript evaluation: (1) encouraging more high quality non-taxonomic papers to address the balance between taxonomic and non-taxonomic papers, and (2) discouraging single species description (see new special issues for single new species description) while giving priority to high quality systematic papers on comparative treatments and revisions of multiple taxa. In addition to review papers and research articles (over 4 printed pages), we welcome short correspondence (up to 4 printed pages) for condensed version of short papers, comments on other papers, data papers (with one table or figure) and short reviews or opinion pieces. The correspondence format will save space by omitting the abstract, key words, and major headings such as Introduction.
