Field infestation and alfalfa seed chalcid (Hymenoptera:Eurytomidae) development in different Medicago clones

Larval development rates of the alfalfa seed chalcid in different Medicago sativa clones were compared, and factors affecting field infestations were tested. Development rates did not differ significantly. Variation in field infestations is probably dependent on factors affecting oviposition. Temper...

Zusammenfassung:	Larval development rates of the alfalfa seed chalcid in different Medicago sativa clones were compared, and factors affecting field infestations were tested. Development rates did not differ significantly. Variation in field infestations is probably dependent on factors affecting oviposition. Temperature, daylength, and resource competition affected field infestation levels and were associated with diapause. Larval diapause appears to be induced in the female parent.
