Review on ecological characteristics and control of aphids

Abstract
Aphids have two different life cycles-incomplete life cycle and complete life cycle. High intensity ultraviolet lights lead to genetic differentiation of aphids. The living habits and behavior of insects are closely related with lights. The conditions of 15~30 ℃ temperature and 70% humidity were optimal for aphids growth. However, there were fewer reports about the response of aphids to lights to our best knowledge. Plant secondary metabolism had effects of poison, repellent, anesthesia and growth inhibition or attracting on aphids. Multifunctional transgenic plants with these metabolites may effectively control aphids. There were great breadth and depth in researches about biological characteristics, environmental factors and control policy of aphids. However, researches about optical characteristic and control policy of aphids for different hosts should be carried out in the future to extent the knowledge about ecological characteristics of different aphid genotypes and their control policy.
