- common bean weevil 大豆象
- Note: Kidney bean include Common bean and Scarlet runner bean. 多花菜豆、普通菜豆习惯上称为芸豆。
- Larvae of the bean weevil cannot move from bean to bean, so they have to compete for limited resources when two or more larvae are in the same bean. 豆象是属于内食性的昆虫,因此当一个寄主豆中有一只以上的幼虫存在时,常有幼虫竞争的现象产生。
- Environmental manipulations were used to explore the effects of larval competition on the life history strategy of the bean weevil, C. maculatus. 试验中取有或无幼虫竞争经历之四纹豆象雌虫,提供寄主豆不足与充裕两种资源状况,以比较两者在成虫期生活史特徵表现上之差异。

- The pollen extine ornamentation of common bean and lima bean were reticulated, and the other three cultivars were foveolated-reticulated. 菜豆和小莱豆花粉外壁呈网状,而绿豆、小豆和长豇豆花粉外壁呈穴网状。
- The accessions with introgression from Mesoamerican to the Andean group could be useful as bridge varieties for common bean breeding. 由中美基因库向安第斯基因库渗透的天然杂交种质可为普通菜豆高产、优质、抗逆育种提供有价值的桥梁品种。
- The effect of NO3 assimilation from dilute, constantly maintained concentrations of N on soybean and common bean nodulation are demonstrated (Table 5). 表5说明了从稀释的维持恒定氮浓度的硝酸盐同化对大豆和菜豆结瘤的影响。
- However, even species such as common bean that frequently respond to nitrogen have a low yield response relative to the N input. 然而,即使像菜豆这样的往往对氮素有反应的种,相对于氮投入来说也仅不大的产量效应。
- The morphological diversity and classification of 324 common bean (Phaseolus vulgaris L.) germplasm resources were researched in the present study. 摘要对324份普通菜豆种质资源的形态多样性进行了研究。
- The variation of each trait among food legumes accessions revealed different,therein protein content of Common bean and Chickpea as well as starch content of cowpea varied most. 不同来源的食用豆类种质资源品质性状比较结果表明,国内绿豆种质资源粗蛋白含量明显优于国外种质资源。
- Shang Qing mao,Qiao Xiao jun.Regulation of external homone on common bean (Phaseolus vulgaris L.)leaf water under the high temperature stress[J].China Vegetables,1998(5):9-12. [9]尚庆茂;乔晓军.;生长调节物质对高温下菜豆叶片水分的调节作用[J]
- The effect of N on nodule development is much more pronounced on common bean than on soybean while soybean nodule initiation is relatively more delayed by N. 尽管大豆根瘤初始时间比菜豆的相对地被氮推迟的更多,但在根瘤发育方面则氮对菜豆的影响比大豆更明显。
- The results show that the larval competition of these bean weevils was density dependent. 寄主豆中起始幼虫比例是竞争成败的关键之一。
- In recent years,a lot of bean weevils have been found in import goods,which are difficult to be controlled. 近年来,在进口货物上截获到很多的豆象,防治困难。
- In this study, the effects of intraspecific and interspecific male interference on the fecundity and longevity of female bean weevils were explored. 因此进行试验探讨对绿豆象及四纹豆象雌虫于同种或不同种雄虫干扰下,其产卵数、卵孵化率及寿命的影响。
- The possi bility of identifying the species of bean weevils by using the electophoresis method on larval lipase isoenzyme was discussed. 由此探讨利用酯酶同工酶电泳法鉴别豆象的可能性。
- The results showed that the morphological diversity was high among the accessions assessed.The average diversity index (1.632) was 40.5% higher than that of alien common bean germplasm. 结果表明,我国普通菜豆种质资源具有丰富的形态多样性,平均多样性指数为1.;632,高于国外材料(1
- Prevention and Cure of Green Bean Weevil in Storage Green Bean and Red Bean 绿豆和小豆种子仓贮时绿豆象的防治
- Knowledge without common sense counts for little. 光有学问而无常识,则这种学问无甚价值。
