Flea beetles are pest of brassicaes, creating holes in the leaves and stems of seedlings. The seedlings are highly attacked as soon as they surface above the ground level and the damage of these beetles are very pronounced on young plants and even cause plant death. Some flea beetles are general feeders, others attack only particular types of plant.
The flea beetle has a narrow host range to plants primarily in the brassicaceae. Most of the flea beetles prefer cruciferous plants which produce allyl isothiocyanate, known as aggregation pheromone of the cabbage flea beetle. The most-preferred hosts are in the genus Brassica (Cruciferae), which include the major agricultural host attacked by flea beetle, oil rapeseed and mustard.
