Examples of lacewinglacewing Lacewing weights were not affected by plant type. In contrast, on non-transgenic plants, lacewings had a choice between feeding on aphids, lacewings or moth larvae and pupae. Two days later 20 first instar lacewing larvae were placed on each plant. The differences in lacewing recovery rates observed in the present study could be due to either lower lacewing survival or changes in predator behaviour that increased lacewing dispersal. A preliminary experiment had shown that lacewing recovery rates were very low if no shelters for lacewings to hide and rest during the day were provided. The offspring were reared for a number of further days on the same plants, in the predator treatment the lacewing larvae were taken off the plant. In predator treatments, one lacewing larva was placed on the lowest leaf pair of the plant to give aphids time to recover before first contact with a predator larva. In fact, other insects, such as lacewings, ladybirds and damsel bugs, are not affected by the genetically modified pollen in question. From the Hansard archive Example from the Hansard archive.
