The excretion of honeydew coats the leaf surfaces and encourages the growth of sooty mold. Advances in Plant Sciences, 9 2: This increasing was probably due the low pluviometric index in those months – 26, 51, and 46 mm Table 2allied to the fact that no chemical control was used.

Within 24 hours after emergence, the insect is covered with a fine wax powder, which gives it a slate blue appearance Dietz and Zetek This reaction is considered an essential step in the phenylpropanoid pathway producing many products, including lignin, involved in plant defense reaction. Description Top of page The following details are based on Smith et al.

Synthetic insecticides should not be sprayed when much of the blackfly population is in the adult stage; therefore, it is recommended to wait 10—12 days for the decrease in adult population allowing the young stages egg and nymphs to emerge which can be controlled before they cause damage [ 40 ].

An Amitus hesperidum population will expire soon after suppression of the citrus blackfly population Nguyen et al. Look for distorted leaves with immature stages on the undersides. Teak plants have high diameter andcanopy, what increases the shading and reduces the wind, possibly favoring a higher aggregation of the pest, which facilitates the maintenance and the increase of citrus blackfly in this field.


In this area, the teak plants are distributed between every three citrus planting lines, totalizing 11 teak lines, plants, and It spread to Cuba inMexico in Smith et al. Among the elicitors, silicon has attracted the attention and interest of researchers.

This resistance is also enhanced with presence of suberin or deposition of suberin lamella covering the cell wall of this process is called suberization. Encarsia perplexa Figure 6 has a lower rate of reproduction than Amitus hesperidumbut has better searching ability.

Journal of Natural History, The aleurocantus about major infestation potential of CBF and its seasonal dynamics is essential for the orientation of management strategies, which may result in the minimization of production losses [ 12 ].

Aleyrodidae [ 3 ]. Aleyrodidae in El Salvador.

Noncitrus trees and shrubs, when they grow by themselves, are not normally attacked by this insect, wogumi they may be when they grow close to heavy infestations on citrus. The kriging map Fig. In Brazil, many are the hosts of the blackfly [ 4 ].

Chemical insecticides and other methods Chemical insecticides have been used to control its infestation; however, this strategy reduces the insect pest of infestations only alurocanthus triggering the imbalance in the environment that in turn, poses threat to nontarget organisms [ 1936 ]. Hosts of the citrus blackfly in Mexico.


The fourth instar, or so-called pupa case, is ovate and glossy black with a marginal fringe of white wax Figure 2. Zea mays oil 0. The CV statistic can be used to identify homogeneous places as well as to help in the sampling planning.

This fact can be observed in this work, where the amplitude ranges from 0. Eggs are laid in a spiral pattern on the underside of the leaf.

Conservative and release of natural enemies like Chrysopidae are potential to control CBF populations. The resistance induced by silicon is expressed in various ways, such as cell wall lignification, papillae formation, or induction of various defense proteins [ 48 ].

Observing those data, it can be inferred that the pest population found again favorable development conditions. From September to October12 samplings were taken, in these specific dates: If you would like to, you can learn more about the cookies we use.
