红铃虫生态对策与防治研究

Study on decision of ecological control for pink bollworm, Pectinophora gassypiella (Saunders)

本文按红铃虫生态对策，从棉花优质高产栽培入手，根据早蕾是一代红铃虫唯一食料，棉花早期过重生殖负担，是引起早衰的重要原因，７月上旬摘除全部早蕾，放弃伏前桃，有利于建立高光效营养体，能较大幅度提高优质棉产量和断绝一代红铃虫食料，使主动控制红铃虫为害成为现实。

Arccording to ecological control for pink bollworm , the cotton early squares were the the only food forthe insect in the first generation. Excision of nil early squares could cut off the food for initiatively controlling thepink blloworm and decreasing the cotton load at breoding stage and increasing the yield of the high quality cotton.
