本科毕业论文(设计) 题 目:影响蝇蛆蛹羽化率因素的探讨 院 系: 专 业: 姓 名: 学 号: 指导教师: 教师职称: 填写日期: 年 月 日 影响蝇蛆蛹羽化率因素的探讨 摘要 为测定总结各种外界因素对蝇蛆蛹羽化率的影响,本课题以家蝇蛹为研究材 料,通过设计多组对照实验研究了蝇蛆蛹在不同光照条件下羽化率的变化,并测 定出最适宜蝇蛆蛹羽化的光照条件。发现随着光照强度的增强,蝇蛆蛹的羽化率 也逐渐升高,但当用100W以上的日光灯来作为光源时,羽化率不再提高。本文 还探讨了其它外界因素对蝇蛆羽化率的影响,包括温度和湿度。发现温度在5°C 以下时,蝇蛆蛹不会羽化,但也不会死亡,在10°C以上时,随温度的升高羽化 率也逐渐升高,当温度高于45°C时,蝇蛆蛹则会大量死亡,经测定最适温度为: 30°C-35°Co另外,在研究湿度时,发现湿度低于15%时,蝇蛆蛹会大量干死, 而在湿度高于95%时,蝇蛆蛹则会大量发霉而死,不能正常羽化,经测定最佳湿 度为:50%—55%o 关键词:家蝇;蝇蛆;蛹;羽化率;光照强度; Study on the Influence Factors of Fly Maggot Pupa WANG Yu-jun (Guiyang University Department of chemistry and materials science 09 science class 550005) Abstract For the determi nation of various external factors on the summary of fly maggot pupal eclosi on rate in flue nee, the topics to Musca domestica pupa as the research material, through the design of multiple groups of controlled experimental study the maggot pupa in different light conditions eclosion rate of change, and the determination of the most suitable fly pupae illumination conditions? With the light intensity enhancement, fly pupal eclosion rate gradually increased, but with more than 100W fluorescent lamp as light source, eclosi on rate no Ion ger in creases ? The paper also discusses other outside factors on the fly maggot eclosion rate effect, including temperature and humidity. It is found that the temperature at 5 DEG C, maggot pupa not eclosion, but not death, in more than 10 DEG C, with the temperature eclosion rate gradually increased, when the temperature is higher than 45 DEG C, maggot pupa will be a large number of death, the determination of the optimum temperature for: 25 degrees - 30 degrees. In addition, in the study of humidity, found the humidity is lower than%15, maggot pupa will dry out and die, and the humidity is higher than %85, maggot pupa will be a large number of mold die, not the normal eclosi on, the determi nation of optimal humidity :%50 ? %55. Key words: maggot, pupal eclosion rate, light intensity. 目录 摘要 2 Abstra
