本研究测定了饲养密度、温度与花绒寄甲成虫产卵量及寿命的关系,及营养缺乏条件下成虫的耐饥饿能力。结果表明,饲养密度和温度对松褐天牛生物型花绒寄甲产卵量均有显著影响。在单盒容积为1 552.5 cm3的饲养盒中,50头/盒和60头/盒的花绒寄甲单雌产卵量最高,但后者总产卵量更高,60头/盒为最佳饲养密度。营养充足时,在23~26℃下,成虫产卵量最大,产卵高峰期为5—7月,10月产卵量最低。人工繁育花绒寄甲的最适温度为23℃。成虫累计死亡率与饲养密度存在显著正相关。30~80头/盒饲养密度下,密度越大,死亡率越高。在营养缺乏条件下,23、26和29℃下的成虫死亡率达50%的时间分别为170 d左右、160 d和120 d。表明该生物型花绒寄甲具有极强的耐饥力,且其寿命长短与温度相关。
In this study, the relationship between stocking density, temperature and the fecundity and longevity of adult malachite, and the hunger resistance of adults under nutrient deficiency were measured. The results showed that both stocking density and temperature had significant effects on the fecundity of the brown cashmere. In the box with a single box volume of 1 552.5 cm3, the numbers of single fecundity per females were the highest in 50 heads / box and 60 heads / box, but the latter had the highest total fecundity, 60 heads / box Good feeding density. Adequate nutrition, at 23 ~ 26 ℃, the largest adult fecundity, spawning peak for May-July, October minimum fecundity. The optimum temperature for manual breeding of cashmere toxins is 23 ℃. Adult cumulative mortality and feeding density there is a significant positive correlation. 30 to 80 heads / box stocking density, the greater the density, the higher the mortality rate. Under conditions of nutrient deficiency, adult mortality rates at 23, 26, and 29 ° C were about 170 days, 160 days, and 120 days, respectively, at 50% mortality. Show that the biological type of cashmere has a very strong resistance to hunger, and its length of life and temperature-related.
