Dynamics of re-migration of sexuparae to their primary hosts in the gall-forming Fordinae (Homoptera: Aphidoidea: Pemphigidae)
- N/A
Migratory flight of sexuparae of gall forming Fordinae to 3 species of Pistacia hosts was monitored using sticky traps. Sexuparae arrived from late March to July. Species arrival time distributions overlapped but modes did not coincide. Although the Fordinae are strictly host-specific, sexuparae landed and reproduced not infrequently on the wrong Pistacia host, a reproductive dead end. These results show that their host-selection ability is imperfect.
