    Genetically modified potatoes expressing Cry 3A protein do not affect aphidophagous coccinellids

  • Original language description

    Field investigations showed that genetically modified Bacillus thuringiensis (Bt) potato plants expressing Cry 3Aa toxic protein were not damaged by the Colorado potato beetle Leptinotarsa decemlineata and contained diverse populations of the aphidophagous coccinellids Coccinella septempunctata, Coccinula quatuordecimpustulata, Hippodamia variegata and Propylea quatuordecimpunctata. The insecticides, alpha-cypermethrin and fipronil, which were used for control of Leptinotarsa in the fields with the non-transgenic standard potatoes caused significant decrease in the abundance of aphidophagous coccinellids. Laboratory experiments revealed that Bt potatoes expressing Cry 3Aa had no effect on the aphid Myzus persicae and that the aphids fed on Bt potatoeshad no effect on the larval development and mortality of C. septempunctata.

    Geneticky modifikované brambory produkující toxický protein Cry 3Aa neovlivňují afidofágní slunéčka

  • Czech description

    Polní pokusy ukázaly, že geneticky modifikované brambory obsahující toxický protein Cry 3Aa z baktérie Bacillus thuringiensis (Bt) nebyly poškozené mandelinkou bramborovou a hostily stabilní populace afidofágních slunéček Coccinella septempunctata, Coccinula quatuordecimpustulata, Hippodamia variegata a Propylea quatuordecimpunctata. Insecticidy alpha-cypermethrin a fipronil, aplikované proti mandelince v polích se standardními kultivary brambor způsobily významný pokles početnosti afidofágních slunéček. Laboratorní pokusy prokázaly, že transgenní brambory neměly vliv na mšice Myzus persicae sající na listech těchto rostlin a že vývoj a mortalita larev slunéčka sedmitečného krmených těmito mšicemi se nelišil od parametrů larev krmených mšicemi ze standardních brambor.
