Study On Some Factors On Ovarian Development And Oogenesis Of Telenomus Theophilae

In this thesis, we studied the structure and development of female internal reproductive organs in Telenomus theophilae, and effects of several facters including diet, temperature on the ovarian development of Telemomus theophilae, and the growth and development of larval, and changes of nutritive matter of parasitized host eggs. 1. The female internal reproductive of adult of Telenomus theophilae is composed of ovary, lateral and median oviduct and soermatheca. During adult stage, the size of ovarian increased with the growth of adult instar, adult stage, then decreased aferward. The size of other organ generally grew with the increase onf adult day age and then keep stabilization. 2. At early pupal stage of Telenomus theophilae, no egg chamber could be observed. At the late pupal stage, egg chambers had occurred, while yolk had not been deposited yet. Mature eggs began to be generated in the ovary at pharate adult stage. Mature egg of Telenomus theophilae, which was deprived of diets as well as host pupae at adult stage, peaked at 18h after emergence. 3.Ovarian development and oogenesis were observed in the female adults of Telenomus theophilae feeding on five diets, i.e., water solutions of honey , sucrose, glucose, fructose and mannose, respectively. It was concluded that , honey , sucrose, glucose and fructose can promot Ovarian development and oogenesis. Comparatively, such a capacity was less effective in the mannose, and fairly little in water. 4Ovarian development and oogenesis were observed in the female adults of Telenomus theophilae at 19,22,25,28 and 31℃. It was concluded that , both rates of ovary growth and oogenesis increased tradually as temperature increased from 19 to 28 ℃. When the temperature reached 31℃, both ovary length and mature eggs were greatly decreased at one day after emergence as compared with those at 25 and 28℃; however , since 2d after...
