Effects of Prestorage Food and Storage Duration on the Fitness of Coelophora biplagiata Adults
摘要
Abstract
This study aimed to explore the effects of pre-storage food and storage duration on the fitness of Coelophora bi-plagiata adults to provide a theoretical reference for the development of storage technology for C.biplagiata adults.Through indoor controlled experiments,the survival rates of C.biplagiata adults stored at various temperatures(7℃,10℃,13℃,16℃,and 25℃)for different durations were analyzed under various pre-storage food(aphids and artificial diet).In addition,the oviposition capacity of adults fed an artificial diet before storage for 35 days and 42 days was determined.The results showed that the survival rate of adults in all treatments showed a decreasing trend with increasing storage duration;at all experimental temperatures,the survival rate of C.biplagiata adults fed an artificial diet before storage was higher than that of adults fed with cowpea aphids and the control group(stored immediately after eclosion).The survival rate of C.biplagiata fed with an artificial diet before storage and stored at 13℃for 42 days reached 73.05%,which was the highest survival rate under all storage conditions.The preoviposition period of C.biplagiata adults stored for 35 days was 6.31 days,which was not signifi-cantly different from that of the control group but was significantly shorter than that of adults stored for 42 days(p<0.05).The total oviposition amounts of C.biplagiata adults stored at 13℃for 35 and 42 days and then reared normally for 30 days were 5 820.67 and 5 635.67 eggs,respectively,which were significantly lower than that of the control group(unstored)(8 209.67 eggs)(p<0.05).After low-temperature storage at 13℃,the survival rates of C.biplagiata adults in the two storage periods reared normally for 30 days were lower than those of the control group.In summary,feeding C.biplagiata adults an artificial diet before storage can improve their survival rate and extend the storage duration,while long-term low-temperature storage can reduce the oviposition capacity of C.biplagiata adults.关键词
