%X Population dynamics of cotton pests and their natural enemies were investigated in fields with different coverings.Field coverings had great influence on the population dynamics.The difference of population dynamics of cotton aphids reached a very significant level between different coverings except for between narrow film and wide film coverings.The number of cotton aphids under complete film covering and straw mulching reached a peak value on July 16,which was five days earlier than that of under no cover...
