The Australian plague locust Chortoicetes terminifera (Walker) exhibits facultative embryonic diapause during autumn. To approximate natural photoperiod changes during late summer and autumn, locust nymphs were reared under different total declines in laboratory photophase (-0.5, -0.75, -1.0, -1.25, -1.5, -1.75, -2. h each lowered in 15. min steps) in a 24. h photoperiod to quantify any effect on the subsequent production of diapause eggs. Induction of diapause eggs was significantly affected...[Show more]
