Laboratory and field studies were undertaken to determine the effects of increased numbers of trichomes on seedling stems, petioles, and first true leaves of Brassica napus L., canola, on the feeding and behavior of the crucifer flea beetle Phyllotreta cruciferae (Goeze) (Coleoptera: Chrysomelidae). Seedlings of 'Westar' canola with genes inserted from

Field studies were conducted at two locations on the Canadian prairies to investigate use of reduced ratios of insecticide-treated seed in controlling flea beetle (Coleoptera: Chrysomelidae, Phyllotreta spp.) damage to canola (Brassica napus L. and Brassica rapa L.).

Abstract The hybrid canolas, Brassica napus hyb. K4-87 and B. napus hyb. K36-87, were tested for two modes of resistance, antixenosis and tolerance, against flea beetles, Phyllotreta spp. In feeding tests in which choices were offered between the hybrids and a standard inbred canola cultivar, B. napus cv.

Abstract Feeding damage by the flea beetles, Phyllotreta cruciferae (Goeze) and Phyllotreta striolata (Fabricius) (Coleoptera: Chrysomelidae), was assessed on Polish ( Brassica rapa L.) and Argentine ( Brassica napus L.) canola grown under conventional and zero tillage regimes, with three different row spacings (10, 20, and 30 cm) and three ...

Abstract Flea beetles (Coleoptera: Chrysomelidae) of the genus Phyllotreta are major pests of cole crops, canola, and related crops in the mustard family (Brassicaceae). Adults may damage seedlings or larger crop plants, impairing crop growth, rendering crops unmarketable, or killing seedlings outright.

Trapping experiments were carried out near Winnipeg, Canada, in the spring of 1987 and 1988 to test attraction of crucifer-feeding flea beetles to volatile glucosinolate (GS) hydrolysis products released from glass vials. Nine isothiocyanates (IC) or mustard oils and three nitriles (CN) were tested.
