“…As a rational approach to control major pests, many integrated pest management (IPM) programmes have been developed, eg in oilseed rape crops,11 rice,12 oranges,13 vegetables14 and soybean 15. However, relatively few reports in the literature document the net profits of IPM programmes in comparison with conventional pesticide strategies.…”

Biorational and regular insecticide applications were evaluated for management of the diamondback moth (DBM) Plutella xylostella in cabbage (Brassica oleracea var capitata) in Karnataka State, India, in 1996 and 1997. The IPM programme, based on the pheromone trap catch threshold of eight moths per trap per night, included utilization of the parasitoid Cotesia plutellae.(250 000 adults ha À1 ), the predator Chrysoperla carnea (2500 eggs ha À1 ), the neem-based chemical nimbecidine (625 ml ha À1 ), the bacterium Bacillus thuringiensis (500 ml ha À1 ), and the synthetic insecticide phosalone (2.8 litre ha À1 ). The IPM programme induced a reduction of trap catches, egg and larval populations and, therefore, a low level of damage to the crop. The economic analysis showed that the cost of the IPM treatments was also considerably lower than that of ordinary insecticide practice (average of $62 relative to $123 ha À1 , respectively). Gross pro®t was also clearly higher in IPM plots than in farmer's ®elds, ranging from $777 to $810 ha À1 in the IPM plots compared with $456 to $462 ha À1 in the insecticide-treated ®elds. As a consequence of lower input costs and higher gross pro®t, net pro®t in IPM treatments was even more favourable, and the economic savings associated with the utilization of the IPM programme amounted to $380

“…This scenario may be especially viable with regard to generalist herbivores, since glucosinolates, a hypothesized antiherbivorant to generalist insects (Giamoustaris and Mithen, 1995), have been bred out of canola-quality rapeseed. Transgenic canola cultivars with insecticidal properties will certainly play a major role in integrated pest management strategies for canola pests (Talekar and Shelton, 1993;Evans and Scarisbrick, 1994).…”

The seeds of a number of Brassica L. species are cultivated for the production of oil. Collectively, the oilseed Brassica sp., generally referred to as rapeseed, supply more than 13% of the world's supply of edible oils and rank third behind soybean and oil palm in importance. The term "canola" was adopted by the Canadians in 1979 and used to describe oilseed Brassica cultivars that produce oils containing less than 2% erucic acid and to describe defatted seed meals with less than 30 pmol g-' of aliphatic glucosinolates. Brassica napus L. canola cultivars are currently dominant in U.S. production, although canola-quality Brassica rapa (synonymous with Brassica campestris) cultivars also exist (Raymer et al., 1990).Production of canola in the U.S. has grown at a modest rate during the last 10 years from virtually O in 1985 to 165,000 ha in 1995 (C. Boynton, U.S. Canola Association, personal communication). As production of canola continues to grow, insect problems are expected to become more serious (Lamb, 1989). This may be particularly true as canola production expands in the southeastern United States and California, where mild winter temperatures are likely to lead to increased herbivory, as compared with the much cooler areas (e.g. Canada), where canola has historically been produced. Ubiquitous lepidopteran Brassica specialists, such as the DBM and the CBL, and generalist lepidop-terans, such as the BAW and CEW, may increase in importance where canola is grown in warmer regions (Buntin and Raymer, 1994). This scenario may be especially viable with regard to generalist herbivores, since glucosinolates, a hypothesized antiherbivorant to generalist insects (Giamoustaris and Mithen, 1995), have been bred out of canola-quality rapeseed. Transgenic canola cultivars with insecticidal properties will certainly play a major role in integrated pest management strategies for canola pests (Talekar and Shelton, 1993;Evans and Scarisbrick, 1994). The objectives for this study were 2-fold. (a) To determine the effect of Bt expression in B. napus on antibiosis for severa1 lepidopteran insects. Unlike the related Bt soybean study (Stewart et al., 1996), in which only few, low-expressing synthetic Bacillus thuringiensis insecticidal crystal protein ( B t crylAc) plants were produced, the likelihood of obtaining a wide range of B t expression is greater using a species that is more amenable to genetic transformation, such as B. napus. (b) To develop biological tools to test models pertaining to biotechnological risk assessment. It is possible that a plant species, such as B. napus, that is able to persist in nonagricultural environments could become more weedy in a transgenic form if the transgene confers an increment of fitness and the plant is naturalized in areas of its cultivation. Thus, we developed the B t canola to ultimately test population-leve1 ecological hypotheses.

“…Infochemicals associated with prey habitat, in this case rutabaga, are clearly involved in the food foraging behaviour of A. bilineata adults, as also shown for several species of parasitoids (e.g., Dicke et al, 1984;Tumlinson et al, 1993;van Alphen & Vet, 1986) and predators (Flint et al 1979;Jalil & Rodriguez, 1970;Pitman & Vité, 1971;Reid & Lampman, 1989). The response to mechanically damaged rutabaga could result from an increased release rate of plant volatiles, possibly sulfur compounds (Blaakmeer et al, 1994;Evans & Scarisbrick, 1994;Roland et al, 1995), which did not persist after 24 h (e.g., scrubbed infested rutabaga without larvae). As also demonstrated in the parasitoids Microplitis croceipes (Cresson) (Eller et al, 1988), Cotesia glomerata (L.) (Mattiacci et al, 1994), and Cotesia rubecula (Marshal) (Agelopoulos & Keller, 1994a;Geervliet et al, 1994), A. bilineata adults chose infested over uninfested prey habitat.…”

Aleochara bilineata Gyll. (Coleoptera: Staphylinidae) adults feed on eggs and larvae of cabbage maggot, Delia radicum (L.) (Diptera: Anthomyiidae), and might be used to control this pest. We undertook tests in a Y‐tube olfactometer to determine if infochemicals are involved in the food foraging behaviour of A. bilineata adults and to precisely determine the potential sources of stimuli. A. bilineata adults oriented toward the stimuli from both the food‐plant of the prey (rutabaga: Brassica napus var. napobrassica (L.) Reichb.) and the prey‐plant complex (rutabaga infested by cabbage maggot larvae), but adults significantly preferred the effluvia of infested to uninfested rutabaga in a choice test. The sources of infochemicals in the infested rutabaga were the cabbage maggot larvae themselves and their frass. However, in a choice test adults preferred the effluvia of the larvae to that of the damaged rutabaga from which those larvae were obtained. It is not expected that a generalist predator uses precise herbivore‐derived signals in food foraging activity, but the preference of A. bilineata adults for the larval volatiles over frass volatiles may reflect the dependence of this species on dipteran pupae for reproduction.
