摘要： Zeugodacus cucurbitae is an important pest of fruit and vegetable crops in tropical and subtropical regions, and high-temperature stress can have different effects on the development and reproduction of successive generations of Z. cucurbitae. To clarify the multigenerational effects of short-time high temperature on the development and reproduction of Z. cucurbitae, the newly emerged adults of the contemporary (F-1 generation) and the next generation (F-2 generation) were exposed to short-term high temperatures of 25 degrees C, 33 degrees C, 37 degrees C, 41 degrees C, and 45 degrees C for 1 h, and the multigenerational (F-1, F-2, and F-3 generation) effects of these temperatures on the development and reproduction of Z. cucurbitae were evaluated. The results showed that (1) when the F-1 was exposed to short-term high temperature, the egg production and lifespan of the F-1 decreased continuously with the increasing temperature, except for the 45 degrees C treatment for 1 h, which stimulated egg production. Only the 41 degrees C group had significantly higher egg production and lifespan than the control group in the F-3. (2) In the F-1 and F-2 that were exposed to short-term high temperature, the F-1 and F-3 were consistent with the results of F-1 that were exposed to short-term high temperature. In conclusion, the effects of high-temperature intensity and frequency on multiple generations of Z. cucurbitae were different. The results of this study can elucidate the effects of short-term high-temperature stress on the growth, development, and reproduction of Z. cucurbitae in different generations, and provide a reference basis for the integrated control of Z. cucurbitae.
