摘　　要：调查结果表明,移栽稻田蜘蛛在分蘖期缓慢增长,拔节到齐穗期迅速增长,齐穗期后呈稳定增长,直播稻田蜘蛛消长曲线与移栽稻田一致,仅迅速增长期比移栽稻田迟10～15d,稳定增长期迟5～10d,移栽稻田蜘蛛种群数量明显高于直播稻田。在水稻不同生育阶段用药时,由于田间环境和各种蜘蛛的发育阶段不同,对水稻后期蜘蛛种群优势种比例有重大影响。The survey result indicated that the spiders grew slowly at tillering stage in transplant rice paddy,they increased rapidly from jointing stage to full heading stage,then increased steadily.The growth and decline curve of direct sowing rice paddy spiders was in accord with transplant rice paddy,but rapid growth than transplant rice paddy late 10～15 days,stable growth 5～10 days later,transplant rice paddy spider population quantity significantly higher direct sowing rice paddy.The use of pesticide in different growth stages in rice paddy,due to environment and the different development stages of spider of rice,which had a major impact on spiders dominant species proportion in rice later.
