Positive and adverse effects of bio-control and conventional chemical control programs in cotton fields were investigated through three successive cotton seasons on the population densities of sucking pests and major natural enemies in commercial cotton fields.
Data indicate the abundance of high population levels of natural enemies and low levels of secondary pests in bio controlled cotton fields meanwhile the opposite was recorded in the chemical controlled ones.
Results of this study so far, certified that, cotton key pests could be significantly reduced through area-wide management approaches of bio-control and to avoid the responsibility of chemical control for cotton major pest populations.
Conventional chemical control for cotton major pests resulted in secondary pests outbreaks. Bio-control applications indicated the abundance of high population levels of natural enemies.
