Abstract
The spatial and temporal distribution of South American leaf miner situation was observed under the conditions of greenhouse in Pingliang Jing river area.The results showed that the rise and fall of the South American leaf miner populations were two high,middle and low momentum in the greenhouse vegetable production period,and adult density gradually decrease in the solar greenhouse from south to north.In the melon,the eggs produced mainly in plants at the top and upper parts,the dangers of young larvae above as the main department.In bean crop in many branches,the eggs produced mainly in the periphery of the plant canopy and middle to outer most.The pupation sites are related with the kinds of greenhouse vegetable crops,mostly to ground to pupate,and more concentrated in the shallow soil surface.关键词
