“…In 2002 and 2003, seed tests were conducted for both BPMV and SMV because of increased populations of the soybean aphid and the inability to discern BPMV from SMV based on symptoms on foliage or seed (Tables 2 and 3). In 2002, based on reports that well-timed application of foliar insecticide may reduce final disease incidence and improve yield and seed quality (Krell et al, 2004), an additional set of seeds of the soybean cultivars selected for the 2001 test was treated with the insecticide imidacloprid to reveal any effect on the characters measured. Although application of imidacloprid as a seed treatment may reduce beetle populations after emergence (Cullen et al, 2003), pairwise comparisons of these cultivars in 2002 showed no significant differences (t test, P 5 0.05) in all characters measured for each soybean cultivar (data not shown).…”

Development of a method to identify field tolerance to bean pod mottle and soybean mosaic viruses (BPMV and SMV) in soybean [Glycine max (L.) Merr.] allowed evaluation of 33 soybean accessions for field response to BPMV and SMV. Based on measurement of parameters that included relative level of virus antigen in seed and mottling of soybean seed coats, three accessions showed tolerance to SMV and BPMV (PI 561353, M90‐18411, PI 507353), eight were tolerant to SMV (MN 1301, M92‐160047, M91‐113037, PI 423826A, A99‐216031, NE 3001, U96‐2408, Colfax), and four were tolerant to BPMV (PI 184042, M93‐326056, M95‐255017, Spansoy 201). Treatment of seed with the insecticide imidacloprid (1‐[(6‐chloro‐3‐pyridinyl)methyl]‐N‐nitro‐2‐imidazolidinimine) did not effect disease control. The relative level of virus antigen in seed harvested from experimental plots was shown to correlate significantly with virus incidence in plots. The data suggest that quantitative assay of virus seed antigen may provide a useful estimate of relative virus incidence in test plots and aid identification of field tolerance to seed‐borne viruses.

“…A single beetle per square metre can cause yield losses of 3 kg ha À1 through pod damage (Smelser & Pedigo, 1992). The bean leaf beetle is also the primary vector of bean pod mottle virus and transmission of this virus to soybean can cause seed discolouration and further yield reduction (Krell et al, 2003(Krell et al, , 2004Bradshaw et al, 2008). An additional issue is the lack of consistent biological control.…”

The bean leaf beetle, Cerotoma trifurcata, has become a major pest of soybean throughout its North American range. With a changing climate, there is the potential for this pest to further expand its distribution and become an increasingly severe pest in certain regions. To examine this possibility, we developed bioclimatic envelope models for both the bean leaf beetle, and its most important agronomic host plant, soybean (Glycine max). These two models were combined to examine the potential future pest status of the beetle using climate change projections from multiple general circulation models (GCMs) and climate change scenarios. Despite the broad tolerances of soybean, incorporation of host plant availability substantially decreased the suitable and favourable areas for the bean leaf beetle as compared to an evaluation based solely on the climate envelope of the beetle, demonstrating the importance of incorporating biotic interactions in these predictions. The use of multiple GCM-scenario combinations also revealed differences in predictions depending on the choice of GCM, with scenario choice having less of an impact. While the Norwegian model predicted little northward expansion of the beetle from its current northern range limit of southern Ontario and overall decreases in suitable and favourable areas over time, the Canadian and Russian models predict that much of Ontario and Quebec will become suitable for the beetle in the future, as well as Manitoba under the Russian model. The Russian model also predicts expansion of the suitable and favourable areas for the beetle over time. Two predictions that do not depend on our choice of GCM include a decrease in suitability of the Mississippi Delta region and continued favourability of the southeastern United States.

“…Many viruses are spread by insect vectors between and within crops. Strategies which suppress insect populations below a threshold level could potentially reduce the damage caused by transmitted plant viruses [8]. Aphids, mites and nematodes are the largest and most significant insect vectors.…”

BackgroundPlant viruses cause many serious plant diseases and are currently suppressed with the simultaneous use of virucides and insecticides. The use of such materials, however, increases the amounts of pollutants in the environment. To reduce environmental contaminants, virucides with insecticidal activity is an attractive option.ResultsA series of substituted ferulic acid amide derivatives 7 and the corresponding hydrogenated ferulic acid amide derivatives 13 were synthesized and evaluated for their antiviral and insecticidal activities. The majority of the synthesized compounds exhibited good levels of antiviral activity against the tobacco mosaic virus (TMW), with compounds 7a, 7b and 7d in particular providing higher levels of protective and curative activities against TMV at 500 μg/mL than the control compound ribavirin. Furthermore, these compounds displayed good insecticidal activities against insects with piercing-sucking mouthparts, which can spread plant viruses between and within crops.ConclusionsTwo series of ferulic acid derivatives have been synthesized efficiently. The bioassay showed title compounds not only inhibit the plant viral infection, but also prevented the spread of plant virus by insect vectors. These findings therefore demonstrate that the ferulic acid amides represent a new template for future antiviral studies.
