Bt crops benefit natural enemies to control non-target pests
Crops producing insecticidal crystal (Cry) proteins from Bacillus thuringiensis (Bt) control important lepidopteran pests. However, pests such as aphids not susceptible to Cry proteins may require other integrated pest management (IPM) tactics, including biological control. We fed aphids on Bt and non-Bt plants and analyzed the Bt protein residue in aphids and compared the effects of Bt plants ...
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 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 کاملCompatibility of two systemic neonicotinoids, imidacloprid and thiamethoxam, with various natural enemies of agricultural pests.
Two systemic neonicotinoids, imidacloprid and thiamethoxam, are widely used for residual control of several insect pests in cotton (Gossypium spp.), vegetables, and citrus (Citrus spp.). We evaluated their impact on six species of beneficial arthropods, including four parasitoid species--Aphytis melinus Debach, Gonatocerus ashmeadi Girault, Eretmocerus eremicus Rose & Zolnerowich, and Encarsia ...
متن کاملResponses of Crop Pests and Natural Enemies to Wildflower Borders Depends on Functional Group
Increased homogeneity of agricultural landscapes in the last century has led to a loss of biodiversity and ecosystem services. However, management practices such as wildflower borders offer supplementary resources to many beneficial arthropods. There is evidence that these borders can increase beneficial arthropod abundance, including natural enemies of many pests. However, this increase in loc...
