本研究还克隆了植物凝集素基因，以解决棉花蚜虫的危害问题，蚜虫属同翅目昆虫，通过吸取植物韧皮部的汁液造成直接危害，又通过传播植物病害对植物造成间接危害，植物凝集素是一类具有特异糖结合活性的蛋白，在植物基因工程中具有较大的应用潜力。

Aphids in the process of inhaling plant sap virus particles and auxiliary proteins also be inhaled, thus completing the process by poison, which also supports the field citrus aphid is non-persistent decline disease vector of disease, while the citrus Huanglongbing is phloem restricted by the bacteria caused the main pathogens present in the phloem, the fleas only by phloem feeding in diseased plants, pathogens in the body through the back to complete the salivary glands in the course of the next through the sieve tube feeding in the secretion of saliva the pathogens into the healthy tree, Citrus Huanglongbing different characteristics with aphid-borne diseases, Huanglongbing to persistent disease.

蚜虫在吸入植物汁液的过程中病毒粒子和辅蛋白同时也被吸入，从而完成获毒过程，这也支持了田间蚜虫是柑桔衰退病等非持久性病害传播介体，而柑桔黄龙病是由韧皮部限制性细菌类引起，病原体主要存在于韧皮部中，木虱只有通过在病株韧皮部取食，病原在体内完成循回到唾液腺中，在下一次取食过程中通过在筛管中分泌的唾液将病原体带到健树，柑桔黄龙病与蚜虫传病特点不同，黄龙病为持久性病害。

In seedling of wheat, implementing the test of Nonpreference by means of releasing alate aphids in order to make them freely select location, the results indicate that most of the wheat varieties have not distinct difference each other, except that Hongmanghong and 885479-2 have distinct difference with others.

在小麦苗期，通过在网罩内人工释放有翅成蚜让其自由选择寄主进行不选择性试验，结果显示，在测定的15个不同抗性材料中仅红芒红和885479-2两个品种表现出与其它品种有较大差异，而大多数小麦品种之间的不选择性没有显著差异。

Chrysopa septempunctata Wesmael is a kind of important natural enemy insects, which can control agricultural and forestry pests effectively, such as aphids, coccids and aleyrodid. Due to wide feeding habits, large appetite, wide distribution and large quantity, it has been paid great attention to by biological control workers.
