Further to "Ladybug, quickly fly away home!" by Claire Gilbert,
I received a flood of inquiries as a result of my article,
"Ladybug, quickly fly away home!" The following is a basic
reference. The article in the London Times was was based upon the
research of Birch, et al.
A.N.E. Birch, I.E. Geoghegan, M.E.N. Majerus, C. Hackette, &
J. Allen, "Interactions between plant resistance genes, pest aphid
populations and beneficial aphid predators," Scottish Crop Research
Institute (SCRI) Annual Report 1996-1997, esp. pp 70-72.

The potatoes were transgenic, using an anti-insect gene encoding
for the snowdrop lectin (Galanthus nivalis agglutinin - GNA).
A numer of ecological "fitness indicators" were used to monitor the
ladybirds fed on aphids from control or GNA potatoes.
