“…THE INTRODUCED FLEA BEETLE, Phyllotreta cruciferae (Goeze) (Coleoptera: Chrysomelidae), has become a signiÞcant agricultural pest on Brassica crops in the United States and Canada (Feeny et al 1970, Lamb 1984, Palaniswamy and Lamb 1992. Agricultural practices for the production of Brassica crops in the northeastern United States, in which the crops are seeded at regular intervals throughout the growing season, provide a constant source of food for many insects that are Brassica specialists, including P. cruciferae.…”

“…Field evaluation often results in high variability due to effects of weather on crop growth, beetle feeding, and beetle density (Palaniswamy and Lamb 1992). Laboratory evaluation is difficult because it is not possible to rear large numbers of P. cruciferae (Lamb 1988).…”

“…Additionally, the period for screening is limited to a short time in spring when flea beetles are most active (Lamb 1988). Scissors have been used to mimic flea beetle injury in resistance evaluations (Bodnaryk and Lamb 1991;Palaniswamy and Lamb 1992;Bodnaryk et al 1994). However, the scissors slice the cotyledon and do not accurately mimic the shape and size of a feeding "pit" created by a flea beetle.…”

Nowatzki, T. M. and Weiss, M. J. 1997. Effects of simulated and flea beetle injury to cotyledons on growth of droughtstressed oilseed rape, Brassica napus L. Can. J. Plant Sci. 77: 475-481. Simulated injury was compared with flea beetle injury on cotyledons of oilseed rape grown at various soil moistures to determine the effects of injury on seedling growth in the greenhouse. The cotyledons of 7-d-old seedlings were injured at 0, 25, 50, and 75% of the total area with a 0.5-mm mechanical pencil or by flea beetles. The soil moisture was maintained at the field capacity, half field capacity, and the permanent wilting point. The growth response of the seedlings was compared for simulated flea beetle injury and soil moisture 7, 14, and 21 d post-injury, and for simulated and flea beetle injury, and soil moisture 7 d post-injury. Simulated injury had the greatest effect on seedlings grown at the field capacity, at 7 d post-injury. At the reduced soil moistures, increased levels of simulated injury were necessary to cause a significant loss in growth. By 14 and 21 d post-injury, compensation to the simulated injury occurred. Simulated injury caused significantly less growth reduction across all injury levels compared with flea beetle injury. However, at injury levels above 25%, both simulated and flea beetle injury had similar trends in growth reduction. The simulated injury tested in these experiments cannot be used in place of flea beetles for resistance screening studies, but may be useful if incorporated as a preliminary tool. Nous avons comparé en serre les effets sur la croissance au dépot d'endommagements artificiels avec ceux des dégàts causés par l'altise des crucifères au cotylédon de plants de colza oléagineux cultivés sous divers régimes hydriques. Les cotylédons de plantules de 7 j étaient endommagés à raison de 0, 25, 50 et 75 % de la surface totale, soit à l'aide d'un stylo à pointe de 0,5 mm, soit par les altises. Le sol était maintenu à la capacité au champ, à la moitié de la capacité au champ et au point de flétrissement permanent. Le comportement des plantules à l'égard des endommagements artificiels et du niveau hydrique était observé 7, 14 et 21 j après les traitements et à l'égard des endommagements artificiels ou par altises et du niveau hydrique, 7 j après les traitements. 7 j après les traitements, l'effet le plus prononcé de l'endommagement artificiel était observé sur les plantules cultivées à la capacité au champ. Au niveau hydrique plus bas, des degrés d'endommagement simulés plus élevés étaient nécessaires pour provoquer une baisse significative de la croissance. Au 14 e et 21 e jours après les traitements, les plantes avaient compensé l'effet des endommagements artificiels. Tous niveaux d'endommagement confondus, le traitement artificiel provoquait une réduction de croissance significativement moins importante que les attaques réelles des altises. Par ailleurs, aux degrés d'endommagement supérieur à 25 %, la réduction de la croissance suivait des tendances semblables quel que soit le mod...

“…Antixenosis is one mode of resisiance that can reduce the level of damage to crops caused by flea beetles, Phyllotreta cruciferae (Goeze) and Phyllotreta strioleta (F.) (Lamb and Palaniswamy 1990; Bodnaryk and Lamb 1991;Palaniswamy and Lamb 1992). Antixenosis describes an attribute of a plant that reduces the level of damage caused by a particular pest (Kogan and Ortman 1978).…”
