Tanggap Fungsional Parasitoid Eriborus argenteopilosus (Cameron) terhadap Crocidolomia pavonana (Fabricius) pada Suhu yang Berbeda

oC, 25 o C, and 30 o C. Data were analyzed using logistic regression to determine the type of functional response. At 20 o C E. argenteopilosus showed type II functional response, while at 25 o C and 30 o C the functional response is type III. Based on surface analysis, the optimal parasitism rate occurred at 22.24 o

Functional Response of the Parasitoid Eriborus argenteopilosus (Cameron) to Crocidolomia pavonana (Fabricius) under Different Temperature

Since the discovery of cryopreservation method for bull semen, cryopreservation become an alternative method for maintaining gamet resources of certain animal which is threatened or near extinction. This technology was then applied to the preservation of embryo, oocyte, ovary and testis. The application of intracytoplasmic sperm injection (ICSI) for which sperm motility is unnecessary had supported the effort to create simplified method such as freeze-drying for sperm preservation. Due to the benefit of ICSI over the conventional in vitro fertilization (IVF) the spermatozoon could be mechanically driven to pass through the zona pellucida and entering the cytoplasm of oocytes prior to fertilization. The freeze-drying method is an alternative method in sperm preservation which ignored the motility of sperm. The sperm resulted from this technique is in drying state, therefore, it might be stored in room temperature or in refrigerator. Many reports have claimed that freeze-dried sperm which is not motile but has an intact DNA was able to fertilize oocytes, even produced offspring in mouse.A screening for antiinflammatory effects was performed on several Indonesian Umbelliferae plants based on the contents of saponins and flavonoids. They were compared with Bupleurum falcatum L. as an introduced antiinflammatory plant. Roots and grains of each plant were collected, dried, and extracted with ethanol. The ethanolic extracts were then analyzed for their saponin and flavonoid contents by gravimetric and UV-vis spectrophotometric method. Antiinflammatory activity test was conducted on carragenin induced rat paw oedema. The results showed that the highest contents of saponin and flavonoid were found in the grains of Apium graveolens L. and showed antiinflammatory effect that was equivalent to that of the root of B. falcatum.
