| Abstract |
Potential trap crops for aphids, Artogeia rapae L. and Plutella xylostella (L.) were evaluated through two experiments during two successive seasons (2005 and 2006). Hosts examined as trap crops were turnip, radish and rocket where cabbage was the trapped crop. In the second experiment, turnip plants were the trapped crop with cabbage, radish and rocket.
The monoculture of cabbage (cabbage x cabbage) was more infested by aphids and P. xylostella when trapped with turnip, but when trapped with radish it was more attacked by A. rapae. While cabbage trapped with rocket was less attractive to the three insects. Also, rocket was of low aphid population with no larval attack.
As to the second experiment, turnip plant was more attractive to the three insects when trapped with rocket then followed by the mono-culture treatment. The less recorded of aphids and A. rapae was detected when turnip was trapped with cabbage. This result proved that cabbage itself was more attacked by the insects. Turnip trapped with radish was less attacked by P. xylostella.
The percentages of aphids parasitized were significant in the difference between treatments. The presence of glucosinolates and their volatile hydrolysis products characterized the cruciferous plants which seem to be the main attractants. Trap crops could protect the cash crop leading to a reduction in pesticides application thus increasing beneficial insects.
