中文摘要:
在云南西双版纳热带地区一种还未被描述属瘿蚊寄生于垂叶榕果内雌花房里并膨大形成虫靠取食花胚组织完成发育。2010定时定点的系统观察和研究瘿蚊的发生规律结果:该种瘿蚊在垂叶榕上发生频率抽样18批果有 17批被瘿蚊寄生,13批果生比率超过了 60%甚至达到 100%瘿蚊寄雌花平均率不超6%平均每榕果内有瘿蚊 1~40只不等瘿蚊寄不仅降低垂叶榕还致命性地影响着传粉榕小蜂殖。在对瘿蚊羽化交配行及其成虫的规律观察中,结果显示:在一榕果里瘿蚊需5~7 d才能羽化完其羽化高峰期出现在第 2~3天;一天内羽化高峰出现在上8:0010:00及晚上 20:000:00;而羽化后瘿蚊活高峰期出现在上8:0011:00雄蚊会帮助雌蚊离开榕果并优先获得交配权雌蚊交配后飞离繁自身树,去寻找适产卵榕果繁后代雄蚊不离开羽化树,而死在繁自身附近这些结果深入研究瘿蚊技术提供了科学依据
英文摘要:
In Xishuangbanna tropical region,an undescribed species of gall midge on Ficus benjamina lays its eggs in the ovary of female flowers,producing a large gall in which the larva feeds on the gall’s tissue to complete its life cycle. We investigated the occurrence of gall midge onF. benjamina through systematic sampling at a fixed time and location in2010. Eighteen crops were sampled and gall midges found to occur in 17 of them. The percentage of figs attacked by gall midges was over 60% in 13 of the crops,reaching as high as 100%. Gall midges parasitized only up to 6% of femaleflowers and on average produced fewer than forty individuals in a single fig. The occurrence of gall midges reduced the number of seeds produced and had a deadly effect on the reproductionof pollinators. We observed the behaviour of eclosion,mating and flight of the gall midge. We found that all gall midges colonizing a single fig took 5—7 days to complete eclosion,and that the eclosion peak appeared in the 2 nd —3rd In one day,eclosion peaks occured at 8:00— day
10:00 in the morning and 8:00—12:00 at night. The peak of activity after eclosion was at 8:00—11:00 in the morning.Male gall midges emerged first and assisted female gall midges to emerge. Once a female had emerged,a male would matewith her. Female gall midges left the natal fig trees after mating to search for appropriate trees for egg-laying. However, after mating,male gall midges died under the natal trees. Our results provide a basis for future study of the technology ofgall midge control. Key words gall midge,occupancy,biological characteristics,pollinating fig wasp,Ficus benjamina
