The okra crop is infested by a number of insect pests, but Amrasca devastans consider among notorious and major insect pests. Many insect and non-insect predators are the sources for control this noxious pest. The crop was observed after 25 days of germinations with 10 days intervals. The insect pest populations and natural enemies were recorded. Jassid population starts from second week of observation and continued till last picking. Different types of natural enemies were recorded at different time periods; among these are many sp. of spider, lady bird beetle, ant, and green lacewing. This study show that Jassid populations appeared after the germinations and infested the crop till the end of crop, jassid populations were significantly increased with increase of plant vegetative growth, different natural enemies appeared at different times, and populations were also increased with increased numbers of jassid per plant. It also observed that natural enemies suppressed the jassid populations and is the good sources of pest control in the field.
