GNA has been shown previously to be toxic towards rice brown planthopper Nilaparvata lugens.

GNA dissolved in a 2 m sucrose solution had no antifeedant effect on female aphid parasitoids Aphidius ervi but had a direct negative effect on their longevity. Thirty-two independently derived plants were subjected to molecular and biochemical analyses. The effects of snowdrop lectin Galanthus nivalis agglutinin GNA on the Glasshouse Potato Aphid Aulacothum solani were tested by bioassays where the protein was incorporated into an artificial diet at a single concentration of 01 w vThe results showed that the presence of GNA in the diet throughout the insects life cycle decreased the fecundity of.

Snowdrop lectin Galanthus nivalis agglutinin. In planta bioassays conducted with T0 or T1 generation PTA lines showed that the growth of aphid Myzus persicae Sulzer was reduced by 89-92 when compared with untransformed UT plants. They found that aphids died when fed on a diet containing the isolated snow drop lectin.

Agrobacterium-mediated transformation in chrysanthemum was studied to prevent the insect pest of aphid Mizus persicae. The SFI1GNA fusion protein comprising of snowdrop lectin Galanthus nivalis agglutinin GNA fused to an insecticidal spider venom neurotoxin Segestria florentina toxin 1 SFI1 was tested for toxicity against the rice brown planthopper Nilaparvata lugens Stål and the peach-potato aphid Myzus persicae Sulzer by incorporation into artificial diets. However its effectiveness against plant-parasitic mites.

BPH feeds by phloem abstraction and causes. Tri-trophic interactions involving pest aphids predatory 2-spot ladybirds and transgenic potatoes expressing snowdrop lectin for aphid resistance Abstract Transgenic crops genetically engineered for enhanced insect resistance should be compatible with other components of IPM for the pest resistance to be durable and effective. General description Lectin from Galanthus nivalis snowdrop is a tetrameric 12 kDa mannose binding lectin.

Sitobion avenae F Schizaphis graminum Rondani and Rhopalosiphum padi L. Application Lectin from Galanthus nivalis snowdrop has been used. Snowdrop lectin inhibits development and decreases fecundity of the glasshouse potato aphid Aulacorthum solani when administered in vitro and via transgenic plants both in laboratory and glasshouse trials.

Snowdrop lectin inhibits development and fecundity of the glasshouse potato aphid Aulacorthum solani when administered in vitro and via transgenic plants both in laboratory and glasshouse trials J. GNA an aphid pest Myzus persicae Sulz and a beneficial predator the 2-spot ladybird Adalia bipunctata L were investigated. To coat ELISA plates.

This study investigated the impact of transgenic wheat expressing Galanthus nivalis agglutinin GNA commonly known as snowdrop lectin on three wheat aphids. Myzus persicae Sulz and a beneficial predator 2-spot ladybird.

Transgene integration varied from one to. An experimental potato line was genetically engineered to express an anti-aphid plant protein snowdrop lectin GNA and assessed for possible interactions of the insect resistance gene with a beneficial pest predator. It is specific to α-13- or 16- linked D-mannose of carbohydrates.

Studies were carried out to determine if susceptibility of the cereal aphid Metopolophium dirhodum to the fungus Pandora neoaphidis was affected by wheat expressing snowdrop lectin GNA.
