Flight capacity determination of adults of Sylepta derogata
摘要
Abstract
[Objective]This study aims to clarify the flight capacity of adults of Sylepta derogata.[Methods]Using an insect flying mill system,the flight capacity for 24 h of male and female adults of S.derogata at 1 day old,and flight parameters for 12 h of adults in different genders and ages of S.derogata were measured;the flight distance,flight time,and flight speed of S.derogata under different mating states,ambient temperatures,and complementary nutrition conditions were also measured in the laboratory.[Results]The adults of S.derogata can be divided into three types:short flying type,intermediate flying type,and long flying type.The dividing points of 24 h cumulative flight time of short and intermediate flying type,intermediate and long flying type were 0.90 h and 2.02 h,respectively.The 1-or 2-day-old adults of S.derogata had relatively weak flight capacity,while the 5-day-old adults had the strongest flight capacity.And there is no significant difference in flight parameters between female and male adults of S.derogata at the same ages.Compared with unmated adults,the flight distance,flight time,and flight speed of 5-day-old mated female adults of S.derogata decreased by 49.85％,35.63％,and 31.97％,respectively;as for 5-day-old mated male adults,the flight distance,flight time,and flight speed significantly decreased by 82.28％,66.58％,and 53.65％,respectively.The 5-day-old adults of S.derogata were able to fly normally under the temperature of 22-28 ℃.Under different ambient temperatures,the average flight distance and speed of male and female adults were 26 ℃＞28 ℃＞22 ℃.The flight time is the longest under 26 ℃.In addition,after feeding on 8％honey water,the flight capacity of 5-day-old unmated male and female adults of S.derogata was significantly better than that of those fed on water or sugar-vinegar solution.[Conclusion]The adults of S.derogata had a certain level of flight capacity,and the ages,mating status,ambient temperature,and complementary nutrition have important effects on its flight capacity.关键词
