【摘要】 本文对甘蔗黄螟雌蛾的性外激素腺体外部形态进行观察,同时还对腺体不同发育时期进行了组织学研究。结果证明甘蔗黄螟性外激素腺体是位于第8～9腹节之间节间膜背面的一个能外翻的褶叠囊状物,表面长满小齿状突起。本文以腺体细胞的高度、细胞核的位置、细胞内液泡的数量等变化作为腺体不同发育时期的细胞分泌活动的形态指标,初步探明了甘蔗黄螟性外激素腺体发育的生长期、成热期和衰落期界限。结合参考本院昆虫毒理研究室饲养黄螟的资料。本文提出用羽化后1～2天的未交配的雌蛾作为提取黄螟性外激素粗提物的材料最为适宜。更多还原

【Abstract】 Observations were made on the pheromone sex gland of the sugarcane yellowb borer (Argyroploce schistaceana) (Snellen) (Tortricidae) , by means of light microscope and electron microscope.The sex pheromone gland of sugarcane yellow borer is an eversible saclike structure situated dorsally in the intersegmental membrane between the eighth and ninth abdominal segments of the female. Sections of candal tip revealed glandular area which is crescent -shaped. The glandular cells are enlarged, columnar, nucleated gland cells.The morphology of the glandular cells is different at various ages of the adult. The position of the nucleus size of the cells and the vacuole-laden cytoplasm are different in different stages.According to these characteristics the development of pheromone gland may be divided into three stages.( 1 ) first (early) stage of development.( 2 )the maturation stage, ( 3 )the atrophied stage.The males are very attractive to the virgin female 1-2 days after emergence and this is the right time to prepare extracts of the pheromone from the females for experimental purpose.更多还原
