“…When this does not happen, i.e., when the trap crop consists of relatively non-preferred host plants, it results in failure of pest management system (Rust 1977;Maguire 1984). Where trap crops have proved successful in managing insect-pests, they were grown as border rows surrounding the main crop or as strips running at right angle to the pests' entry route into the crop (Srinivasan and Krishna Moorthy 1991;Luther et al 1996;Mitchell et al 2000;Asman 2002;Rousse et al 2003;Barari et al 2005;Fearson et al 2005).…”

The large white butterfly, Pieris brassicae (L.), is an important pest of Indian mustard, Brassica juncea (L.) Czern., and inflicts heavy damage to all the above ground plant parts with strong yield reducing impacts. Farmers have few practical options other than to spray insecticides to protect their crop. In this study, an attempt was made during 2012-2013 and 2013-2014 crop seasons at Ludhiana, India, to evaluate Ethiopian mustard, Brassica carinata A. Braun as a trap crop to manage this pest as an alternate pest management strategy. B. carinata borders surrounding B. juncea were compared to chemically protected B. juncea and control (without B. carinata borders) plots for their effects on P. brassicae infestation and grain yield. Oviposition preference of adult butterflies was studied in a two-choice test in field cages, while the effect of two host plants on larval performance was studied under laboratory conditions under no choice conditions. B. juncea plots bordered with B. carinata harbored significantly lower larval population compared to control B. juncea plots during both the seasons. The grain yield in the bordered plots was also significantly higher than that from control plots and was statistically non-significant from that obtained in chemically protected plots. Female butterflies showed distinct oviposition preference for B. carinata over B. juncea and the larvae reared on B. carinata completed development in shorter period and grew bigger and heavier than those reared on B. juncea. Results indicated that B.carinata has potential to be used as trap crop to manage P. brassicae.Keywords Brassica carinata Á Brassica juncea Á Oviposition preference Á Pieris brassicae Á Push-pull strategy Key message• With the aim to provide environmentally sound ''alternative'' pest management strategy against Pieris brassicae, Ethiopian mustard was evaluated as a trap crop around Indian mustard. • Ethiopian mustard is highly preferred for egg laying and feeding by adults and larvae, respectively, compared to Indian mustard and can be used as an effective trap crop against this pest. • However, further research is required to optimize trap cropping system for maximum efficiency under field conditions.

“…The damage to oilseed Brassica crops through flea beetles exceeds US$ 300 million annually in North America (Knodel and Olsen, 2002). Psylliodes chrysocephala (cabbage stem flea beetle) is the major stem-mining pest of oilseed rape (Barari et al, 2005) and an important pest of other Brassica spp. in Europe (Bromand, 1990;Bartlet and Williams, 1991;Bartlet et al, 1996;Vig, 2002;Valantin-Morison et al, 2007).…”

“…The cabbage seedpod weevil therefore needs to find a host plant at two stages of its life cycle: upon emergence from pupation in the summer (pre-diapause weevils), and upon emergence from hibernation the following spring (post-diapause weevils) (Bartlet , 1993).

“…Turnip rape showed good potential as a trap crop for oilseed rape pests, particularly the pollen beetle, as its odour was more attractive to pests than that of oilseed rape (Cook et al, 2006). A study by Barari et al (2005) examining turnip rape as a trap crop to reduce oilseed rape infestation, and the effects of insecticide treatment on pest incidence and larval parasitism, showed that the turnip rape trap crop borders reduced P. chrysocephala but not C. pallidactylus infestation of oilseed rape plots. Treatment of the trap crop with insecticide had little effect on either pest or parasitoid incidence in the oilseed rape.…”

-Brassica crops are grown worldwide for oil, food and feed purposes, and constitute a significant economic value due to their nutritional, medicinal, bioindustrial, biocontrol and crop rotation properties. Insect pests cause enormous yield and economic losses in Brassica crop production every year, and are a threat to global agriculture. In order to overcome these insect pests, Brassica species themselves use multiple defence mechanisms, which can be constitutive, inducible, induced, direct or indirect depending upon the insect or the degree of insect attack. Firstly, we give an overview of different Brassica species with the main focus on cultivated brassicas. Secondly, we describe insect pests that attack brassicas. Thirdly, we address multiple defence mechanisms, with the main focus on phytoalexins, sulphur, glucosinolates, the glucosinolate-myrosinase system and their breakdown products. In order to develop pest control strategies, it is important to study the chemical ecology, and insect behaviour. We review studies on oviposition regulation, multitrophic interactions involving feeding and host selection behaviour of parasitoids and predators of herbivores on brassicas. Regarding oviposition and trophic interactions, we outline insect oviposition behaviour, the importance of chemical stimulation, oviposition-deterring pheromones, glucosinolates, isothiocyanates, nitriles, and phytoalexins and their importance towards pest management. Finally, we review brassicas as cover and trap crops, and as biocontrol, biofumigant and biocidal agents against insects and pathogens. Again, we emphasise glucosinolates, their breakdown products, and plant volatile compounds as key components in these processes, which have been considered beneficial in the past and hold great prospects for the future with respect to an integrated pest management.Brassicas / insect pests / chemical ecology / trophic levels / glucosinolates / isothiocyanates / defence mechanisms / biocontrol / trap crops / integrated pest management

Comment favoriser la r egulation biologique des insectes de l' echelle de la parcelle a celle du paysage agricole, pour aboutir a des strat egies de protection int egr ee sur le colza d'hiver ?Durant ces soixante dernieres annees, les modes de production agricole des pays du Nord ont permis d'assurer l'augmentation de la productivite agricole, grâce a une intensification importante des modes de conduite via le recours a une forte mecanisation et a une utilisation massive d'intrants. Ces nouvelles pratiques agricoles ont bel et bien conduit a une augmentation de la productivite mais ont egalement entraîne des impacts environnementaux et sanitaires considerables. D'abord, l'utilisation massive de fertilisants et de pesticides est reconnue comme ayant des effets nefastes sur les ecosystemes, et sur la gestion durable des bio-agresseurs, via l'apparition de resistance (Aubertot Abstract: How to enhance biocontrol of insects from the field scale up to agricultural landscape in order to propose integrated management strategies on winter oilseed rape? Continuous increases in the use of synthetic fertilisers and pesticides in agro-ecosystems have led to an increase in crop production, but also to a simplification of landscape and a decline in biodiversity at the field, cropping system level. Changes at landscape level, such as regional farm specialisation, increases in field size and the removal of hedgerows and woodlots suppression, have strengthened this tendency towards decline. The loss of biodiversity in agro-ecosystems has increased the need for external inputs, as important functions are no longer provided by beneficial species. This has led to an apparently inevitable reliance on petrochemicals in production systems. However, many scientists are arguing that this reliance on pesticides could be considerably reduced by making better use of biotic interactions. This review explores, in the light of recent studies, possible ways to increase beneficial biotic interactions in agro-ecosystems, and to improve bio control pest management at field and landscape scales. This review also points out the possible integrated cropping system on oilseed rape and concludes on the future research that has to be engaged to achieve the goal of improvement the natural bio-control of pests. For example at field scale, it has been shown that the choice of cultivar, the sowing date and nitrogen fertilisation practices can be manipulated to prevent interactions between pests and crop, in either time or space . We have also highlighted that beneficial biotic interactions may result from appropriate changes to the habitats of beneficial species, mediated by soil management and cover or mixing species utilisation. Finally, changes achieved at landscape scale appear promising. However, these approaches frequently also present drawbacks that may not necessarily be outweighed by the beneficial effects. Endly, we propose the approaches to design integrated crop management systems to reduce the damage of pests. However, major research efforts a...
