Provenance & quality
Third instar M. viciae aphid individuals were set onto 2 week old plants at densities varying from 5 to 200, with each plant placed in a 47.5 x 47.5 x 47.5 cm Bug Dorm cage. One female Aphidius megourae parasitoid was placed in each cage for a 24-hour period, after which point it was removed. Aphids were then left for 2 weeks before all mummies were counted. We used two set ups: unlit controls and artificial light at night at 20 lux and control, 1 lux and 20 lux. After two weeks all mummified aphids were counted. To test for the behavioural response of parasitoids to different light intensities, 100 3rd instar M. viciae aphids were placed on a 3 week old broad bean. This infested plant was then placed in a cage in complete darkness. Different light treatments were then applied over the top of the cage, these being 0 (control) 1, 5, 20, and 100 lux, measureable at the height of the plant. 20 mated female A. megourae parasitoids were then released into the cage, and were left for one hour. After one hour the locations of the parasitoids (on the or away from plant) were noted. To test for parasitoid attack rate during day and night, single broad bean plants with 60 3rd star M. viciae aphids per plant, and placed in a cage. These aphids were left to settle for 1 day before being placed in incubators (Percival Model 1-30 vl) set to 18 degrees Celsius with a 12:12 day night cycle. A single, mated female A. megourae parasitoid was placed in each cage, and left for 12 hours in either dark or light settings. After 12 hours the parasitoid was removed and placed in another cage, again with 60 3rd instar aphids and left for a further 12 hours at the opposite light treatment.
