Zusammenfassung: | <jats:p>1. Diapause is generally believed to entail costs that manifest themselves as decreased survival, rate of development, and/or reproduction after diapause completion. The present study is a first step in investigating such diapause costs in the spider mite Tetranychus urticae.</jats:p><jats:p>2. The relationship was assessed between diapause duration and the post‐diapause life‐history traits of longevity and egg production, under six photoperiods at 19 °C.</jats:p><jats:p>3. The relationship between diapause duration and longevity was negative under five out of six treatments; in three cases this negative relationship was significant.</jats:p><jats:p>4. Most evident were the negative correlations between diapause duration and rate of oviposition, peak rate of oviposition, and total egg production. These phenotypic correlations suggest that there may be a trade‐off between diapause duration and post‐diapause reproduction.</jats:p> |
