温度对瓜实蝇实验种群生长发育及生殖的影响研究
Effect of temperature on the development and reproduction of Bactrocera cucurbitae(Coquillett)population
摘要
Abstract
[Objective]The present experiment was conducted to study the effect of temperature on developmental and reproductive stages of Bactrocera cucurbitae population (Coquillett) in order to provide basic information for its integrated control. [Method]The B. Cueurbitae populations were artificially fed at five constant temperatures (15, 20, 25, 30 and 35℃) and the development, reproduction and their survival rates were determined by artificial feeding method during various developmental stages. [Result]The threshold temperatures for the development of eggs, larva, pupa, pre-oviposition period and generation of B. Cueurbitae were 10.56, 7.33, 10.77, 9.72 and 10.77℃ respectively, and the effective accumulated temperature of them were 12.68, 117.91, 107.15, 364.43 and 602.17 d·℃, respectively. The pupa could not survived at 35℃. The female adults were found to produced maximum eggs (1428.3 eggs per female) under the condition of 25℃, while minimum egg production (240.3 eggs per female) was recorded at 15℃. The population trend indices of B. Cueurbitae was recorded over 1, and it was recorded as maximum (447.37) at 25℃, followed by 301.19 at 30℃. [Conclusion]The B. Cueurbitae population was found to be developed normally in the range of 15-301], which was the optimum temperature for its development and reproduction.关键词
