摘要

在棉花生长季节对侵染棉花的常见棉铃虫、粉棉铃虫、果胶棉铃虫和刺棉铃虫进行了荧光假单胞菌和白僵菌的鉴定。连续喷3次，每次间隔15 d，测定了害虫和幼虫含量的降低。考虑了荧光假单胞菌对籽棉产量的间接影响，并与未处理对照进行了比较。本研究结果表明，叶面施用荧光假单胞菌和白僵菌对棉铃虫侵染的影响最大。土壤和叶面施用荧光松的棉种产量最高。

FIELD EVALUATION OF PSEUDOMONAS FLUORESCENS AGAINST THE PINK BOLLWORM, PECTINOPHORA GOSSYPIELLA AND THE SPINY BOLLWORM, EARIAS VITELLA.

Pseudomonas fluorescens and Beauveria basianna were evaluated in cotton growing season against the common bollworms that infested cotton, pink bollworm, Pectinophora gossypiella and the spiny bollworm, Earias vitella. Reduction in the infestation and larval content was determined after three successive sprays with 15 days interval. The indirect effect of Pseudomonas fluorescens on seed cotton yield was considered and compared with the untreated check. Results of the present study revealed that the foliar application of P. fluorescens and Beauveria basianna treatment exhibited the greatest reduction in bollworms infestation. Soil and Foliar application of P. fluorescens, was recorded with the highest amount of seed cotton yield.
