摘要
【目的】为明确温度对军配盲蝽Stethoconus japonicus生长发育及繁殖的影响。【方法】以悬铃木方翅网蝽Corythucha ciliata为猎物,置于15、20、25、30和35℃的人工气候箱恒温条件下饲养军配盲蝽,统计恒温处理下军配盲蝽发育历期、存活率和成虫繁殖力等指标,计算其发育起点温度与有效积温。【结果】在15-35℃内,军配盲蝽各虫态发育历期均随温度升高而缩短。军配盲蝽卵、若虫、卵-成虫、产卵前期及世代存活率随温度升高均先增加后降低,在25℃下的存活率最高。军配盲蝽全世代的发育起点温度为10.59℃,有效积温550.22日·度。随着温度升高,成虫寿命和雌虫产卵期逐渐缩短,雌虫寿命较雄虫长,25℃时单雌平均产卵量最大,为218.36粒,35℃时最低,为47.62粒。25℃下军配盲蝽实验种群趋势指数值最大,为I=18.01,是20℃的2.05倍,30℃的7.97倍。【结论】25-30℃最有利于军配盲蝽实验种群的增长。研究结果为室内人工繁殖军配盲蝽提供基础参考数据。
[Objectives]To determine the effect of temperature on the development and reproduction of laboratory populations of Stethoconus japonicus.[Methods]The developmental duration,survival rate,fecundity and population parameters of S.japonicus feeding on Corythucha ciliate,were investigated in an artificial climate chamber at a range of temperatures(15,20,25,30) and(35±1)℃.[Results]The average duration of various developmental stages of S.japonicus shortened as the temperature increased from 15 to 35℃.S.japonicas required just 84.35 d to complete its life cycle at 15℃,but 1985 d at 35℃.The survival rate of eggs,nymphs,egg-adults,pre-laying stages and a complete generation,of S.japonicus,first increased,then decreased,with increasing temperature.Survival was highest at 25℃,the developmental starting temperature of a complete generation was 10.59℃,and the effective accumulated temperature was 502.48 day-degrees.The adult life span and female laying period gradually shortened with increasing temperature.The life span of females was longer than that of males.The average number of eggs laid per female was highest at 25℃(218.36),and the lowest at 35℃(47.620).The highest population trend index of S.japonicus was I=18.01 at 25℃,which was 2.05 times higher than that at 20℃,and 7.97 times higher than that at 30℃.The optimal temperature for nymph development,survival,adult reproduction and population growth was 25℃.These results provide a basic reference for the captive breeding of S.japonicus feeding on C.ciliata.[Conclusion]The most suitable temperature range for population growth of S.japonicus,in terms of developmental duration,survival rate,developmental rate,longevity and fecundity,is 25-30℃.
