3年的观测说明,温度是影响柑桔大实蝇蛹发育的主要生态因子。测得发育起点温度为10.57℃,有效积温为567.90日度。在贵州都匀自然条件下,预蛹期2—2.5天,蛹期160—170天。据室内恒温处理,蛹在30℃以上不羽化,在30—35℃高温下5—8天死亡;20—25℃是最适发育温区,20℃时蛹历期52—58天,25℃时32—36天;5—10℃时蛹不能羽化,在此低温下最长成活期达247天;-5-0℃时,蛹的忍耐致死期为6—18天。变温处理和光照对蛹的羽亿元影响。蛹对土壤的最适含水量要求为15—20％。
Three years of observations show that temperature is the main ecological factor that affects the development of pupae in the citrus fruit fly. The measured onset temperature was 10.57 ° C and the effective accumulated temperature was 567.90 days. Duyun in Guizhou under natural conditions, pre-pupal stage 2-2.5 days, pupal stage 160-170 days. According to the room thermostat treatment, the pupae did not emerge above 30 ℃ and died 5-8 days at the high temperature of 30-35 ℃. The optimum developmental temperature range was 20-25 ℃. The pupae period was 52-58 days at 20 ℃, When pupae can not emerge at 5-10 ℃, the longest survival time reaches 247 days at this low temperature; when the temperature is -5-0 ℃, the lethality of pupae is 6-18 days. Effects of Temperature Treating and Illumination on Pupae of Pupae. Pupa requirements of the soil moisture content of 15-20%.
