Multigenerational Effects of Short-Term High Temperature on the Development and Reproduction of the Zeugodacus cucurbitae (Coquillett, 1899)

Zeugodacus cucurbitae is an important pest of fruit and vegetable crops in tropical subtropical regions, high-temperature stress can have different effects on the development reproduction successive generations Z. cucurbitae. To clarify multigenerational short-time high temperature cucurbitae, newly emerged adults contemporary (F1 generation) next generation (F2 were exposed to short-term temperatures 25 °C, 33 37 41 45 °C for 1 h, (F1, F2, F3 these evaluated. The results showed that (1) when F1 was temperature, egg production lifespan decreased continuously with increasing except treatment which stimulated production. Only group had significantly higher than control F3. (2) In F2 consistent temperature. conclusion, intensity frequency multiple different. this study elucidate growth, development, generations, provide a reference basis integrated
