These studies were carried out in 1961-1964,in Nanking,KiangsuProvince.The results are summerized as follows:1.On the rice plant during the tillering-prebooting stages,thenewly-hatched larvae of Tryporvza incertulas(Walker)always leave theleaf-portion,than crawl downward the leaf sheath and bore into theplant.Such orientation behavior is not determined by positive geotropism.2.The feeding site of the newly hatched larvae seems to dependupon the developmental stage and the variety of the rice plant.For in-stance,on the tilleting stage plant,the distance between the bore andthe basal part of plant is less than 10cm;on the prebooting stage plantis 10-20 cm;after the booting stage is more than 30 cm.3.The feeding behavior of the newly hatched larva in response tothe various stages of rice-plant was found to coinside with the ovipo-site selection of the adults.In the different stages of rice plant,theleaf sheath of fillering and booting stage were found to be preferredby the first instar larva than that of the prebooting and grain-fillingstage.4.An attractant substance for the newly-hatched larva was foundto exist in leaf-sheath and in the booting stage of rice plant;whereasin the leaf tissue,an anti-feeding substance may possibly exist.5.The order of establishment quantity of the newly-hatched larvaon the rice plant is:seedling of 17 days>seedling of 44 days;for thesurvival of first instar larva is:old seedling>young seedling.6.The compound“oryzonone”synthesized by the authors wasfound to be attractive to the newly-hatched larva in certain concen-trations.The cause in change of the orientation site and establishment quan-tity of the newly-hatched larva is also discussed.

本项工作的目的在于探求水稻三化螟Tryporyza incertulas(Walker)初孵幼虫在稻株上的定向特性,为鉴定水稻的不同生育期、品种植株间的抗螟性能做一些基本工作。其次,以人工合成的“稻酮”进行蚁螟趋化反应试验。工作系于1961—1964年进行。所得结果初步表明:1.在稻株上的定向部位:蚁螟侵入孔距稻株基部的相对高度为,分蘖期<10厘米;圆秆期10—20厘米,孕穗期后>30厘米。在生长期相同的植株上,籼稻>粳稻。入侵途径以叶鞘侧部的脉间蛀入为主,部分咬脉而入。2.蚁螟在分蘖期至圆秆期稻株上主动选择叶鞘部位入侵,并非由“向地性”所支配。3.蚁螟对各生育期水稻叶鞘组织的趋化反应与成虫的产卵选择性相吻合,即偏选分蘖期与孕穗期的稻株(或叶鞘)。4.在稻株叶鞘及孕穗穗苞内含有诱致蚁螟的物质,而在稻叶叶片组织内可能含有拒食作用的物质。5.蚁螟着生数量,在秧苗上为,17天秧>44天秧;在分蘖与圆秆期稻株上,籼稻>梗稻。6.一定浓度的人工合成“稻酮”能明显地引起蚁螟的嗅觉反应。

Investigations were carried out on the orientation behavior of adult Campylomma chinensis Schuh (Hemiptera:Miridae) toward plant hosts Lantana camara,L.camara cv.‘Flava',and L.montevidensis (Spreng.) Briq.(Verbanaceae).Surveys on three Lantana plants showed that the distribution of C.chinensis in inflorescences was not related to floral color (partial correlation coefficient was 0.240,P=0.147,n=40),but to the number of Thrips hawiiensis Morgan (partial correlation coefficient was 0.512,P<0.0001,n=40) and...

对马缨丹(Lantanacamara)、黄花马缨丹(Lantanacamaracv.‘Flava’)和紫花马缨丹(Lantanamontevidensis)花序上中华微刺盲蝽(Campylommachinensis)的密度调查结果表明,中华微刺盲蝽在3种颜色马缨丹花序上的分布与花序颜色无关(偏相关系数为0.240,P=0.147,n=40),但与花序中的黄胸蓟马数量和花序中小花数的偏相关系数分别为0.512(P<0.0001,n=40)和0.451(P<0.0001,n=40),达到极显著水平.中华微刺盲蝽对不同颜色粘卡的试验也表明,该盲蝽寻找植物寄主时,视觉刺激并不起作用.四臂嗅觉仪的试验结果表明,中华微刺盲蝽对马缨丹的气味有强烈的趋向作用.采用固相微萃取和气相质谱联用技术分析表明,3种马缨丹花序的挥发物有7种相同的化学成分.
