Abstract (sommario):
During a study on the parasitoids of the imported cabbageworm, Artogeia rapae (L.) (Lepidoptera: Pieridae), undertaken in 1993 and 1994, we recovered Cotesia rubecula (Marshall) (Hymenoptera: Braconidae) for the first time in Quebec, Canada. Samples were taken from pesticide-free plots of cabbage, broccoli, and Brussels sprouts located at Ste-Clotilde (45°09′N, 73°41′W) and L'Acadie, Quebec (45°18′N, 73°21′W), as described by Godin and Boivin (1998). In addition, survival of diapausing C. rubecula was evaluated after a 5-month incubation at 4°C (Godin 1997). Both A. rapae and C. rubecula are introduced species and originate most likely from Europe (Richards 1940). Artogeia rapae was discovered in 1860 in Quebec (Harcourt 1963), and C. rubecula was first reported in 1963 in British Columbia (Wilkinson 1966).

Abstract (sommario):
AbstractThe insect parasite Cotesia rubecula (Marshall) shows a long-day, photoperiodic response that results in diapause in the eonymph. Within the region of the critical photoperiod, the diapause response is modified by temperature and by the duration of the developmental period of the larval parasite, but in field populations in Vancouver, diapause is predominantly a response to short photoperiods. There is evidence that the parasite's response is largely independent of the host's response. Once diapause is induced, there is an obligatory dormant period of at least 2 months after which diapause terminates when specific-heat requirements are fulfilled. The estimated heat requirements are used to predict the date of diapause termination and the emergence of parasite adults in the field. Parasite activity begins almost 6 weeks after that of its host.The critical photoperiod for populations in Vancouver, Canada, lies between 15- and 16-h photophase but in Canberra, Australia, the critical photoperiod is less than 13 h. The significance of this difference in the diapause response of the 2 introduced populations is discussed and recommendations are made for further biocontrol efforts.

Abstract (sommario):
Rhizobacteria–induced systemic resistance (ISR) and pathogen-induced systemic acquired resistance (SAR) have a broad, yet partly distinct, range of effectiveness against pathogenic microorganisms. Here, we investigated the effectiveness of ISR and SAR in Arabidopsis against the tissue-chewing insects Pieris rapae and Spodoptera exigua. Resistance against insects consists of direct defense, such as the production of toxins and feeding deterrents and indirect defense such as the production of plant volatiles that attract carnivorous enemies of the herbivores. Wind-tunnel experiments revealed that ISR and SAR did not affect herbivore-induced attraction of the parasitic wasp Cotesia rubecula (indirect defense). By contrast, ISR and SAR significantly reduced growth and development of the generalist herbivore S. exigua, although not that of the specialist P. rapae. This enhanced direct defense against S. exigua was associated with potentiated expression of the defense-related genes PDF1.2 and HEL. Expression profiling using a dedicated cDNA microarray revealed four additional, differentially primed genes in microbially induced S. exigua-challenged plants, three of which encode a lipid-transfer protein. Together, these results indicate that microbially induced plants are differentially primed for enhanced insect-responsive gene expression that is associated with increased direct defense against the generalist S. exigua but not against the specialist P. rapae.

Bibliography: leaves 133-148. Examines sugar foraging in the field by adult female parasitoid wasp, Cotesia rubecula (Hymenoptera, Braconidae), to determine its effect on fecundity and lifespan. In the field, the area in which wasps search for sugar is likely to depend on the degree of association of hosts with nectar or honeydew, supporting the hypothesis that sugar encounters in the field happen opportunistically during host foraging activities. The survival gained by sugar feeding my often be severely limited by quality and quantity of sugary food and extrinsic mortality factors such as adverse weather conditions and predation, so the need for food must be studied in relation to a species' adaptation to its environment. Concentrations of sugar sources may distract wasps from host-foraging when the density of hosts is low. This has implications for flower propagation in agro-ecosystems with a view to supporting natural enemies of insect pests.
