在实验室条件下,以桔小实蝇三龄初幼虫为繁育寄主,考察了15、18、21、24、27及30℃6个梯度恒温对前裂长管茧蜂生长发育与繁殖的影响.结果表明:在试验温度范围内,前裂长管茧蜂的世代发育历期随着温度的升高而缩短,发育历期由15℃时的45.7d降至30℃时的15.2d.温度过低或过高对前裂长管茧蜂的生长发育均有一定的抑制作用,15℃与30℃时寄生蜂的幼期存活率分别为10.2%和31.3%,而在24～27℃时,幼期存活率维持在50%左右.在试验设定的温度范围内,前裂长管茧蜂成蜂的寿命随着温度的升高而缩短,雌蜂的寿命稍高于雄蜂.前裂长管茧蜂的繁殖力以24℃时最高,能繁育74.2个后代,其次为27、21与18℃,分别能繁育53.4、35.7与31.6个后代,而在其他温度条件下,前裂长管茧蜂繁育的后代不超过20个.在15～24℃的范围内,种群中雌性比率随着温度的升高而增加,在24℃时最高为0.59;在21～27℃范围内,后代种群中以雌性个体为主.从综合反映昆虫种群生长发育与繁殖情况的指标内禀增长率来看,27℃时的内禀增长率最高,为0.1318;其次为24、21、30与18℃,相应的内禀增长率分别为0.1239、0.0747、0.0318和0.0187.而15℃时的内禀增长率与种群趋势指数分别为-0.0240和0.8,种群数量呈负增长趋势.24～27℃是前裂长管茧蜂生长发育与繁殖的适宜温区.
Under the laboratory conditions, the first instar larvae of the orange fruit fly were used as the breeding host, and the effect of six gradient incubations at 15, 18, 21, 24, 27 and 30 ℃ on the growth and reproduction of A. californica was investigated The results showed that in the experimental temperature range, the developmental age of Brachionus calyciforra decreased with the increase of temperature, and the developmental period decreased from 45.7d at 15 ℃ to 15.2d at 30 ℃. Too low or too high had some inhibitory effects on the growth and development of C. elegans, and the survival rates of parasitoid at 15 ℃ and 30 ℃ were 10.2% and 31.3% respectively, while at 24-27 ℃ , The survival rate of juvenile remains at about 50% .In the experimental temperature range, the lifespan of adult beetles of C. elegans shortens with the increase of temperature, and the life span of female bees is slightly higher than that of drone The reproductive capacity of Braconidae was the highest at 24 ℃, which could breed 74.2 offspring, followed by 27, 21 and 18 ℃, respectively, which could breed 53.4, 35.7 and 31.6 offspring, respectively. At other temperatures, The number of progeny of Braconidae breeding does not exceed 20. In the range of 15 ~ 24 ℃, the female ratio in the population increases with the increase of temperature, the highest is 0.59 at 24 ℃; in 21 ~ 27 Within the range, the offspring population is dominated by female individuals.According to the intrinsic rate of increase of index, which reflects the growth, development and reproduction of insect population, the intrinsic rate of increase at 27 ℃ is the highest, 0.1318, followed by 24, 21, 30 and 18 ℃ respectively, the corresponding intrinsic rate of increase was 0.1239, 0.0747, 0.0318 and 0.0187 respectively, while the intrinsic rate of increase and population trend index at 15 ℃ were -0.0240 and 0.8, respectively, with a negative trend of population growth. ℃ is a suitable temperature zone for the growth, development and reproduction of C. elegans.
