OBSERVATIONS ON ARTHROPODS FROM THE SEED CABBAGE CROP DURING THE GROWING SEASON AND UNDER THE CLIMATIC CONDITIONS IN BACAU.

White cabbage (Brassica oleracea L.) is a biennial species. The culture intended for seed production is realized in the fall. Insect pest attack is a key factor contributing to low seed yield. Data show that, several arthropos were found to attack cabbage crops and have been identified as belonging to five orders. The most numerous order was represented by the order Coleoptera with 34% of the collected specimens followed by the orders Araneae and Hemiptera, each with 22% and the orders Hymenoptera and Trombidiformes with 11% each. This paper presents the arthropod fauna of the seed cabbage crop during the growing season in the climatic conditions of the Bacau area, focusing on the pest species of this crop. Pests affecting seed cabbages at Vegetable Research and Development Station from Bacau include: rape beetle - Meligethes aeneus (Fabricius, 1775), Cabbage stem weevil - Ceutorhynchus pallidactylus (Marsham, 1802), Cabbage seed pod weevil - Ceutorhynchus assimilis (Paykull, 1800), Cabbage aphid - Brevicoryne brassicae (Linné, 1758).
