前言柑桔红蜘蛛是防治次数最多的柑桔害虫,因而,防治费用也多。由于红蜘蛛一年发生多达10—12代,影响其发生量的因素极为复杂,所以给发生量预测增加了困难。柑桔红蜘蛛的发生量,决定于红蜘蛛的基数和寄主植物,以及气象等环境条件对二者的影响;也

Preface Citrus red spider is the most control citrus pests, therefore, prevention and control costs more. Since spider mites occur for up to 10-12 generations a year, the factors that affect their occurrence are extremely complex, making it difficult to predict the occurrence.
