Fleas fleas or white scales (Coccidae, Homoptera order family) is one of the pests on the plants. These fleas suck the fluids in the body of the host (Napitu et al.). Ticks are polifag white, almost all types of plants potentially stricken white lice oeh. The extent of damage caused by the attack of Pseudococcus SP. ranging from medium to high attack. Risk posed on attack high, that could result in the failure of cultivation. Pest mite White has more than 100 host plants of the genus of plant family 62. The spread of head lice is very easy through the white seeds yield duplication plants vegetatively (Kalshoven 1981). This is in accordance with the conditions of the teak seedlings in the nursery as the result of multiplication by cuttings and shoots. Based on the observations, the mite insects found along white black ants are seen in Figure 16. According to William (2004), insect infestation of white symbiotes with ants. Mutualisme symbiosis between ants and fleas ants protect IE white white lice from its natural enemies attack, and from the bad weather, as well as aiding in the transmission or dissemination of these white lice. The result of the symbiosis, the ants get dew honey produced by this mite as the ants food source.White lice pest can spread it easily with the help of the wind, carried away by the seeds, carried away by a human, or be carried away by other animals. This allows because of the size of small bugs. The white leaf and suck the fleas excrete toxins and led to chlorosis, leaf malformation, dwarf, and produces honey dew exudate to can cause death in plants (Director General Horticulture 2010). Result observation of teak seedlings in the nursery shows the large number of seedlings that underwent a malformation on leaves like in Figure 17a. In addition, teak is also found on the leaves of honey dew in Figure 17b. This is in accordance with the Director-General of Horticulture (2010).
