At no time did parasitoids physically touch the central filter paper discs that had received no treatment or treatment with hexane alone.
The waxy layer of the vitelline membrane was then removed by sequential treatment with isopropanol and hexane.
The control stimulus was a similar pipette containing a filter paper impregnated with a 10-ml aliquot of hexane.
Control treatments with 1 ml droplets of hexane alone did not stimulate aphid movement.
The hexane extract was removed for column chromatography taking extreme care not to damage the mosquito sample.
Samples were desorbed with 5 ml of hexane.
This was diluted with hexane for easier application; the hexane soon evaporated.
The hexane was evaporated and the oil weighed.
