摘要:

在林间自然条件下观察褛裳夜蛾的羽化、求偶、交配与产卵等行为,通过林间诱蛾试验验证其性趋向.结果表明: 褛裳夜蛾的成虫于6月初开始羽化,至6月中旬达到羽化高峰,整个羽化期持续将近1个月,日羽化高峰在21:00—23:00.雌雄性比1:1.02, 雄蛾先羽化.雌蛾最早在羽化3天以后才开始求偶,一周左右表现最为强烈,3~5日龄的雌蛾求偶高峰期在2:00—4:00,而6~7日龄的求偶高峰期在24:00—2:00,求偶高峰期随虫龄的增加逐渐提前.褛裳夜蛾雌雄成虫一生只交尾1次,交尾高峰期在4:30前后,光期未见交尾.雌蛾的交尾活动受日龄影响显著,6和7日龄蛾交尾能力最强,其交配时间最短, 其他日龄雌蛾交尾时间较长.褛裳夜蛾卵单粒散产,未交配雌蛾产卵期为6.2天,交配后的雌蛾产卵期为4.9天; 产卵行为主要发生在夜间,产卵高峰期在0:00—2:00,该时段的产卵量达到总产卵量的69.6%.雌、雄蛾交配过后平均寿命分别为15.44和12.22天, 雌、雄蛾未交配的平均寿命分别为19.78和16.11天.种内个体间表现为雌蛾引诱雄蛾, 6~7日龄处女雌蛾林间诱蛾量最高,显著高于其他日龄(P<0.05).

Abstract:

Catocala remissa (Lepidoptera: Noctuidae)is a defoliator of Populus euphratica. In this paper, adult reproductive behavior, such as eclosion, courtship, mating and oviposition, was investigated under natural conditions in the woods and the sexual tendency of C. remissa was verified by field trap trial. The results showed that the eclosion period of C. remissa lasted for about a month with a peak of eclosion at the mid-June. The daily emergence peak occurred from 21:00 to 23:00. The ratio of female to male was 1:1.02 and the male emerging before the female. The mating and calling behavior was observed at the scotophase. The females called in three days after emergence. The calling peak varied with age of female. In their whole life,both the male and female mated only once. The mating peak occurred at 4:30 and mating behavior was influenced by female age. The mating ability is strongest when females were 6 or 7 days old in which the mating time was shortest. The mated female oviposited sporadically and the oviposition period was 4.9 d. The oviposition behavior of all female moths occurred during the scotophase. The oviposition peak occurred 0:00-2:00 by which the egg quantities accounted for 69.6% of the total. The lifespan of unmated female and male was 19.78 days and 16.11 days on average, whereas that of the mated female and male was 15.44 days and 12.22 days on average. In the field experiment virgin female moths were used as lure to trap the males. The number of the males attracted by the 6 or 7 days old virgin females was the most, significantly more than that trapped by older females. The results showed that the male was attracted by the virgin female before mating within the species. In conclusion, the adult reproductive characters are the first link in controlling the population of C. remissa by interfering sexual communication. The result laid the foundation for sex pheromone-relevant researches.

Key words: Catocala remissa, reproductive behavior, sex pheromone
