The pea moth Cydia nigricana (Lepidoptera: Tortricidae) is the key pest of the pea Pisum sativum (Fabaceae). Alternative pest control techniques need to be developed since efficient control options are scarce. Field studies in Northern Hessen, Germany, in the years 2006 - 2008 demonstrated a strong correlation between the seasonal flight period of C. nigricana and the phenology of pea. With this starting point, we propose to study the olfactory space between the pea plant and the pea moth, aiming to identify volatile cues encoding host recognition and host finding in pea moth females, and the potential use of these compounds for control of the pea moth. As a first step, two-choice experiments in the laboratory concerning complex plant odours were conducted to study the preference between different phenological development stages of pea plants using male and female C. nigricana (mated and non-mated). Males and non-mated females showed no preference, whereas mated females clearly preferred flowering pea plants. To study the host finding behaviour and upwind orientation of C. nigricana we conducted wind tunnel experiments, using pea plants in different phenological development stages. The preference of mated females for the pea flower has been confirmed and additionally, high attraction of mated females for the late bud stage was recorded. Overall, the flower and the late bud stage of P. sativum seem to be the most important phenological development stage of pea for host finding behaviour of C. nigricana. The next steps in this study are the identification, selection and characterisation of behavioural active pea plant compounds.
