Influence of temperature and photoperiod on the developmental biology of the obliquebanded leafroller, Choristoneura rosaceana (Harris) (Lepidoptera:Tortricidae)

Creator:

Ranga Rao, Gangavalli V.

Abstract:

Developmental thresholds and thermal unit (degree day) requirements for eggs, different larval instars, pupal stage and preoviposition period were determined for the obliquebanded leafroller (OBLR), Choristoneura rosaceana (Harris). Separate thresholds and degree day requirements were determined for males and females, but differences between the sexes were not significant. However, there...
