HIGHLIGHTS

• who: dell from the Baghdad University have published the research work: ‫‪2017‬‬ ‫‪Laborarory Studies on the Effect of Population Density of the Scale Insect‬‬ ‫‪Parlatoria blanchardi on Some Biological Aspects of the Predator‬‬, in the Journal: (JOURNAL)
• how: Result showed that larval‬‬ ‫‪development periods are inversely proportional to the density of the scale insect P. Blanchardi.‬‬ ‫‪The shortest larval period was 20 days on the density of 80 nymphs However the period of‬‬ ‫‪larval development was increased to 33.5 days on the density of 25 nymphs with significant‬‬ ‫‪diffrences.
