Volatiles obtained by air entrainment of aphid infested plants were more attractive to A. ervi than those from uninfested plants, in both behavioral bioassays and activity of pure compounds, which significantly increased parasitoid responses to these compounds.

Using harmonic radar, it is shown for the first time a striking ontogeny to honeybee orientation flights, suggesting a learning process adapted to changes in weather conditions, flower availability and the needs of bee colonies.

Bumble bees were found to be able to learn a pure odorant when it was presented in paired association with a sugar reward, but not when odour and reward were presented in an explicitly unpaired procedure, which suggests an associative basis for this olfactory learning.
Strategies Involved in the Location of Hosts by the ParasitoidAphidius erviHaliday (Hymenoptera: Braconidae: Aphidiinae)

This learning ability provides the parasitoid with behavioral plasticity to adapt its responses to suit prevailing foraging opportunities, and attempts are being made to manipulate field populations using host pheromone lures.
Relative importance of semiochemicals from first and second trophic levels in host foraging behavior ofAphidius ervi
Aphidius ervi probably overcomes the reliability-detectability problem by selectively responding to herbivore-induced, volatile, semiochemical cues emitted by the first trophic level and by distinguishing between the volatiles induced by host and nonhost aphids.

It is shown here that the behaviour of non-target insects can also play a part in determining how their populations will be affected by Bt plants.

Physical and chemical cues influencing the oviposition behaviour of Aphidius ervi

- 1 March 2000
This work confirms the existence of an aphid cuticular kairomone, and shows that host exuviae, which also elicited strong and persistent oviposition reactions from A. ervi females, appear to be a good alternative source of ovipositional k airomone(s).
