Planococcus ficus is a polyphagous insect, not only feeds on Vitis vinifera but also other hosts. Your damages are direct by their presence in the cluster and indirect by their droppings containing sugars which are used by ants and serve as a substrate for mushrooms, I give appearance blackened in trunks, arms, leaves and clusters, preventing adequate photosynthesis and marketing. For better management of pest was performed population fluctuation of Planococcus ficus in the 2014-2015 campaign in the Carrizales batch of Agricola Andrea SAC located in Ica at an average temperature of 19.4ºC and average relative humidity of 74.5%. The batch was divided into 5 sections and 4 plants were taken at random from each sector recording the number of egg masses, nymphs I, nymphs II + III, young females and gravid females in the neck, trunk, arms, leaves and clusters . The results were: Postharvest 2014 the most abundant population was found with a maximum peak of a total of 2,050 individuals and were mainly in the arm. In budding and flowering begins increase in the neck. In harvest and postharvest amounts increase slightly in all plant organs mainly in the neck, followed by the trunk, arm, leaves and clusters. Throughout the campaign was found in total 548 egg masses, 3609 nymphs I, 1408 nymphs II + III, 1327 young females and 1525 gravid females. Concluding, the destole before evaluations was an important role for the efficiency of phytosanitary applications and counting populations, temperature and relative humidity influenced the growth of populations and their behavior. The nymph I is the most mobile was found in greater numbers than other stadiums including adult female. In leaves and clusters pest is present.
