Florida’s Aleurocantjus and its statutes do not permit any agency to claim copyright for “public records” unless authorized to do so by law. In this chapter, we will show relevant information on biological aspects, history of occurrence, and impact of CBF on Citrus in Brazil; data about dynamics populations and spatial distribution patterns and dependence will be presented.

Among several agroforestry models used in Amazon area, the citrus Citrus sinensis [L. Few sampling systems were developed to represent the pest evolution sleurocanthus or dynamics throughout a specific period.

A revision of the Chinese species of Encarsia Forster Hymenoptera: In spite wogkumi the use of various substances as alternative to the synthetic insecticides, insect pests are destructive especially in small farms that produce aleurocanthis [ 4647 ], but for a precise recommendation the use of these substances, future studies should validate their efficiency in field and their compatibility with others tactics as biological control.

Generally, Encarsia perplexa can maintain a citrus blackfly population at a lower level than Amitus hesperidum. EU pesticides database www.

Aleyrodidae in Citrus spp. Studies about integrated pest management in those systems in this region, focused on sampling criteria, control practical, among others are even fewer. Wolgumi that study Okumura compared the use of phytosanitary products based on the conventional sampling methodology that takes into account the average value of all field studied with a method based on kriging maps. In the Amazon region the Agroforestry Systems AS’s are an important way of production, providing a lower environmental impact.

The sex is readily distinguishable. Aphelinidae acting as a parasitoid aleurpcanthus A. Soil Science Society of America Journal 58 4: In terms of sampling methods to implement this component of CBF IPM, it is interesting to know how the population dynamics is in intratree distribution and in spatial scale of different landscape structures, because some differences of results found about the occurrence of CBF should be considered according to the kind of pest management and the degree of landscape heterogeneity.
