The Metabolic Basis And Hormonal Regulation For Flight And Reproduction Trade-off In A Female Wing-dimorphism Cricket,Velarifictorus Aspersus

The phenomenon of wing polymorphism is an important adaptation mechanism for insects to cope with environmental changes.This phenomenon has been reported in various insects.In this paper,we studied the female cricket of Velarifictorus aspersus the long-winged and short-winged females in different days,the number of days after emergence,and the nutrient content in the flying and reproductive organs.The fifth day after emergence The long-winged females were treated with different lengths of slings to compare the nutrient content of the worms;the long and short-winged female adults on the fifth day after emergence were treated with different doses of juvenile hormones and precocious vegetatives.The nutrient content in the body,in turn,explores the metabolic basis and hormone regulation of the flight and reproductive physiological trade-offs of long-winged(LW)and short-winged(SW)femalesThe comparison of nutrient content in the female adult between long-winged (LW)and short-winged(SW)showed that the protein content of the long-winged female adult was higher than that of the short-winged female adult,and the protein content of the short-wing female adult increased rapidly,which was significantly higher than that.Long-winged female adults,and the content of phospholipids was significantly higher than that of long-winged females within 9 days after emergence.In contrast,the total lipid and triglyceride content in the long-winged female adult was higher than that of the short-winged female within 9 days after emergence,and the glycogen content was not significantly different between the long-winged(LW) and short-winged(SW)females.The results of various nutrient contents in the flying muscle,ovary and fat of the female adult of the winged type II showed that the protein,total lipid and triglyceride content in the flying muscle of the long-winged female were significantly higher than that of the short-winged female.There is no significant difference in the phospholipid and glycogen content.The contents of protein,total lipids,triglycerides and phospholipids in the ovary of short-winged females were higher than those of long-winged females after the fifth day of emergence,and there was no significant difference in glycogen content within 9 days after emergence.There was no significant difference in the amount of metabolites in the fat body between SW and LW females.The results of the nutrient content of the long-winged female adults on the fifth day after emergence showed that the content of nutrients in the long-winged females after 5 minutes flight has no effect.but 30 minutes of flight can promote the synthesis of phospholipids in the long-winged female.After treatment with different doses of juvenile hormone on the fifth day after emergence,the results of nutrient content in the worm showed that high concentration of juvenile hormone treatment can promote the content of phospholipid in the long-winged female.These results indicate that there are differences in the metabolic material distribution patterns of long and short-winged female adults.The long-winged female adult synthesizes more triglycerides and proteins to develop flying muscles,while the short-winged female adults synthesize more proteins,triglycerides and phospholipids to develop the ovaries.In addition,the 30-min flight behavior promotes the synthesis of phospholipids in long-winged females,which may mean that longer-term flight behavior can accelerate the growth of long-winged females into the breeding stage.At the same time,high concentrations of juvenile hormone treatment can promote the synthesis of insect phospholipids in long-winged females,which may mean that high concentrations of juvenile hormones can also promote the growth of long-winged females into the breeding stage.
