The western flower thrips Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae) is a cosmopolitan, polyphagous insect pest that causes bronzing to fruit of strawberry (Fragaria x ananassa). The main aim of this study was to test whether mass trapping could reduce damage and to predict whether this approach would be economically viable. In semi-protected strawberry crops, mass trapping...
Genetically modified (GM) crops are used extensively worldwide to control diploid agricultural insect pests that reproduce sexually. However, future GM crops will likely soon target haplodiploid and parthenogenetic insects. As rapid pest adaptation could compromise these novel crops, strategies to manage resistance in haplodiploid and parthenogenetic pests are urgently needed. Here, we develope...
BACKGROUND A simulation model is used to explore the influence of biological, ecological, genetic and operational (management) factors on the probability and rate of glyphosate resistance in model weed species. RESULTS Glyphosate use for weed control prior to crop emergence is associated with low risks of resistance. These low risks can be further reduced by applying glyphosate in sequence wi...
Evolution of resistance by pests is the main threat to long-term insect control by transgenic crops that produce Bacillus thuringiensis (Bt) toxins. Because inheritance of resistance to the Bt toxins in transgenic crops is typically recessive, DNA-based screening for resistance alleles in heterozygotes is potentially much more efficient than detection of resistant homozygotes with bioassays. Su...
The Canadian Food Inspection Agency (CFIA) regulates environmental releases of plants with novel traits, which include transgenic plants such as Bt crops. Bt crops are regulated in Canada because they express insect resistance novel to their species. Commercialization of crops with novel traits such as the production of insecticidal Bt proteins requires an approval for environmental release, as...
The cultivation of transgenic pest-resistant cropsmay reduce pesticide application, improve production and increase economic benefit. Breeding and planting transgenic pest-resistant crops is expected to be a promising way to control pests. Pest-resistant transgenic researches in China began in the early 1990s. In 1992, China developed the country’s first Bt protein gene (CryIA gene) with the in...
Trehalose-6-phosphate synthase (TPS), as the key enzyme for the synthesis of plants trehalose, has effects of enhancing its anti-dehydration, as well as protecting biofilm, proteins, and others from harm. Additionally, reproductive isolation between species can be broken with transgenic technology, and beneficial gene of other species can be transformed and utilized to improve resistance of cro...
