The effect of photoperiod, temperature, humidity, rainfall and moisture were examined on the annual migration ofLuprops tristis (Fabricius, 1801) (Coleoptera: Tenebrionidae) from rubber plantations to shelters, and the induction of 9 months dormancy thereafter. Results confirm the role of rainfall-mediated wetness from summer showers as the cue that induces dormancy in Luprops tristis and provide further proof to the function and significance of moisture in diapause induction in tropical insects. Other factors did not have any significant independent effect on migration and dormancy induction. Reserve food accumulation by teneral adults well ahead of the onset of adverse conditions and the non-return of beetles to the field in short-term favorable conditions strongly indicate that Luprops tristis has evolved the ability to "predict" and avoid adverse conditions and the inheritance of dormancy-regulating factors from the parent generation. 展开更多
