An experiment on the population fluctuation of the diamondback moth; Plulella xyloslefla (L.) and the cabbage looper; Trichop/usia ni (Hubner) on cabbage was carried out at EI-Manawat village, Giza Govemorate along two succes~ive seasons; 2001·2002 and 2002-2003. Results revealed that the diamondback moth was abundant during fall and the beginning of winter, while the cabbage looper occupied summer and fall seasons throughout the two seasons of study. Two high peaks of the former pest population (eggs, larvae and pupae) occurred from the second week of September to the last week of November, as compared with three peaks for T. ni; in the second half of July, along September and from the second half of October to the first half of November. The two insects were rare through January and February.
