| Abstract | ||
| Using differently coloured sticky paper traps counts of captured insects of . cabbage aphid, Brevicoryne brassicae as well as of its predators; Orius spp. and Paederus a/fierii and its parasitoid Aphido/etes aphidimyza were carried out in two years (1998 and 1999) in Fayoum governorate. The obtained data showed that the white sticky traps were the best for capturing the cabbage aphid B. brassicae followed by the yellow one, then came the blue, green and red traps. The time course of count of trapped insects showed two phases: the first started on zs" of February and ended on 1 th of March with a ~eak on 13th of March, while the second phase started on 3'd of April and ended on 24t of April with a peak on io" of April. The other coloured sticky traps were less efficient and it can be arranged in the descending order as follows : white > yellow > blue > green> red. All traps showed the time phases of the time course of captured counts. Concerning the predators and parasites of B. brassicae, white traps were far more efficient in capturing them, while green traps were far inefficient. | ||
