AGERATUM CONYZOIDES, THE STERILITY EFFECT ON OXYA HYLA

Menthanol extract of Ageratum conyzoides and precocene I have similar effect on adult male Oxya hyla testicular cell cycle. Cell cycle was interfered on treatment with A. conyzoides extract. The sub-stages of prophase stage like leptotene, Zygotene, pachytene, diplotene and diakinesis were still developed, but the next stages were inhibited. The cell cycle was completely blocked in the prophase stage with no further development. A. cony-oides extract has activity to sterility and hence is important for reducing the population of the O. hyla.
