Interactions between transgenic plants, the diamondback moth and natural enemies
Several Brassica crops have been transformed with -endotoxin genes from Bacillus thuringiensis (Bt) to provide resistance to the diamondback moth (Plutella xylostella) and other lepidopteran pests. This paper describes studies of the direct and indirect effects of Bt plants on a parasitoid of P. xylostella using Cry1Acexpressing transgenic oilseed rape (canola) as an example. The braconid wasp ...
متن کاملPlant-mediated interactions between whiteflies, herbivores, and natural enemies.
Whiteflies (Homoptera: Aleyrodidae) comprise tiny phloem-sucking insects. The sessile development of their immatures and their phloem-feeding habits (with minimal physical plant damage) often lead to plant-mediated interactions with other organisms. The main data come from the polyphagous pest species Bemisia tabaci (Gennadius) and Trialeurodes vaporariorum (Westwood), which are intricately ass...
متن کاملNatural Enemies Delay Insect Resistance to Bt Crops
We investigated whether development of resistance to a Bt crop in the presence of a natural enemy would be slower than without the natural enemy and whether biological control, in conjunction with a Bt crop, could effectively suppress the pest population. Additionally, we investigated whether insecticide-sprayed refuges of non-Bt crops would delay or accelerate resistance to the Bt crop. We use...
متن کاملNatural Insect Enemies for the Control of Chromolaena Odorata
Chromolaena odorata (L.) King & Robinson (Asteraceae: Eupatorieae), a shrub of neotropical origin, is a primary threat to the conservation of biodiversity, and to pastoral and crop agriculture and forestry in the subtropical regions of South Africa. It invades much of the sugarcane growing areas in KwaZulu-Natal and thus impacts negatively on the South African sugar industry. The plant presents...
متن کاملSymbionts modify interactions between insects and natural enemies in the field
Eukaryotes commonly host communities of heritable symbiotic bacteria, many of which are not essential for their hosts' survival and reproduction. There is laboratory evidence that these facultative symbionts can provide useful adaptations, such as increased resistance to natural enemies. However, we do not know how symbionts affect host fitness when the latter are subject to attack by a natural...
