Results of interpopulation crossing test of mating, fertilization rate, embryo growth and hatchability under the condition of cage feeding indicated that:(1) due to difference in body size, morphology, habits and characteristics and reproducing season, crossing fertility between wild Japanese quail in China and domestic quail population was lower than that of intrapopulation mating, but fertilized egg through reciprocal crossing could be incubated and produced F1 without prezygotic isolation; (2) crossing of wild male quail? female small-type domestic quail produced the best effect among all combinations of reciprocal crossings.
通过关于笼饲环境下交配行为、受精率、胚胎发育、种蛋孵化率的种群间杂交试验证明：由于体量、形态、习性、繁殖季节性的差异，我国境内的野生日本鸣鹑与家鹑群体之间的杂交能育性低于同种群交配水平，但可以实现正、反杂交，产生受精卵、孵出杂种一代，不存在合子前生殖隔离；在正反杂交组合中，以野雄鹑X小型雌家鹑的效果最好。

Assulta and the induction of GST activity by nicotine and capsicine in H. assulta provided partial supports for the hypothesis that diet breadth was governed by detoxification abilities. The results also indicated that two sibling species had different strategies of adaptation to toxic substances: H. assulta saves expenditure of nutrients and energy by restricting their countermeasures to a few potentially toxic compounds. H. armigera, by contrast, must be prepared to counter a wider range of potential toxins. 5. Compared with parental species, hybrids of reciprocal hybridization had significant difference in feeding preference for hot pepper.
结果显示，广食性的棉铃虫在中肠羧酸酯酶和谷胱甘肽-S-转移酶活性方面高于寡食性的烟青虫，但烟青虫谷胱甘肽-S-转移酶活性可以被寄主植物内的烟碱和辣椒素所诱导，表明解毒酶活性在一定程度上影响着植食性昆虫的食性广度；同时也暗示着二近缘种对有毒的次生物质采取不同的适应策略：烟青虫有选择地对付种类较少的植物次生物质以减轻营养和能量的消耗；棉铃虫则必须对付存在于其寄主植物内的种类繁多的有毒次生物质。
According to market investigation, as to many weak points in the use of common oscilloscopes at present, the design of our products (VD252/422/252/622M) adopts the computer mouse to control the measurement positions of parameters and uses such functional switch as voltage level difference, time difference and reciprocal of time difference.
