中文摘要:为了栎旋木柄天牛Aphrodisium sauteri Matsushita生殖为的方式点,寻找有效手段本试观察栎旋木柄天牛的生殖为,并在林间尝试了成虫诱集结果表明:雌雄成虫之间表现出吸引作用,近距离时雌雄可相互吸引而远距离时雌引诱力更强。室内试验中求偶时间会随着成虫的衰弱而增加。成虫交配主要发生于白天羽化出1~14日龄雌虫和 2~13日龄雄均可次交配。成虫一次完整交配平均需时70. 12 min交配后护平均仅3. 86 min一次完整交配中,日龄成虫的交配历时交配间隔历时及交配次数都存在差异各日龄成虫的交配间隔历时均大交配历时交配或产卵历对雄交配行为的影响显大虫。产卵前期平均30.71 h每产1粒卵平均需时99.58 s并随日龄增长显著加长每头雌平均每日产卵量总产卵量7. 8926. 20虫多在白天产卵,用产卵器触探树皮表面寻找产卵部位主要于树皮裂缝枝条疤痕内一般每次产卵1卵表面无覆盖物。
英文摘要:
  • In order to find effective control methods for Aphrodisium sauteri Matsushitathe reproductive behavior of this longhorn beetle was observed and a field test for trapping adultsconducted The results show that females and males mutually attract each other at short distancesbut at long distances females tend to attractmales In a laboratory experimentthe duration of calling behavior increased with adult ageMating mainly took place in daytime 1st14th day females and 2nd13th day males could mate several times after they left eclosion holes A complete mating lasted 70. 12min on averageThe average protective duration after mating was 3. 86 min In a complete matingthe duration of matinginterval of mating and frequency of mating differed among adults of different ages The interval of mating was always longerthan the duration of mating Previous reproductive experience had a greater influence on malesmating behaviors than on femalesThe average preoviposition period of females was 30. 71 h Females tookon average99.58 s to lay an eggand oviposition time increased with female age The average number of eggs laid by a female was 7. 89 in one day and the total number of eggs laid by a female in her life time was 26. 20. Females touched the bark surface with their ovipositors tofind oviposition sites and usually laid eggs in daytimeEggs were mainly laid in cracks in bark and scars on branchesUsually only one egg was laid at a time and the eggs were uncoated
