“…In Brazil, many are the hosts of the blackfly [4]. In Rio de Janeiro, for example, recently-three new host plants for A. woglumi were identified: Artocarpus heterophyllus (Moraceae), Pouteria caimito (Sapotaceae), and Struthanthus flexicaulis (Loranthaceae) [32]. In spite of the use of various substances as alternative to the synthetic insecticides, insect pests are destructive especially in small farms that produce fruit [46,47], 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.…”

“…In Pará, there has been an increase in parasitism by microwasps which was not identified, with parasitism reported up to 90% [31]. In Rio de Janeiro, for the first time, the association of Encarsia pergandiella Howard (Hymenoptera: Aphelinidae) acting as a parasitoid of A. woglumi nymphs infesting Citrus latifolia leaves was recorded [32].…”

“…The potential of these predators to reduce the population of many pests is a factor, which has been reported by several researchers as promising on control of CBF [23,33]. As well as the occurrence of species Chrysopidae (Neuroptera) [32] was common, and the species of Coccinellidae (Coleoptera) was also recorded as the natural biological control of CBF in C. latifolia orchards in Brazil. In fact, species of Chrysopidae and Coccinelidae (Coleoptera) are important in the control of CBF, for example in the north region of Brazil, 11 species of Chrysopidae and Delphastus pusillus (Le Conte) (Coccinelidae) were observed preying CBF [11,34,35].…”

Citrus BlackFly (CBF) always represented a threat to Brazil. The impact of the introduction in Brazil of the CBF has led to serious economic and environmental consequences. 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. We are intending to emphasize in this chapter the main challenges and opportunities of some important tactics to promote sustainable management of CBF in citrus, such as: (i) biological control, (ii) chemical and others methods, and (iii) induced resistance.

“…Citrus blackfly (Aleurocanthus woglumi Ashby, 1915), an exotic pest widely disseminated in Brazil, is capable of infecting more than 300 species including fruit trees and ornamental plants. Citrus species, considered its primary hosts, are highly susceptible to infestation by this pest (EPPO, 2008;RAGA et al, 2016;ALVIM et al, 2016). Citrus blackfly eggs are creamy white until the second day after laying, resemble curved rods, with spiral-shaped, concentrating on the abaxial surface of leaves, adhered by a short peduncle.…”

The main objectives of this study were to determine the content of secondary metabolites (carotenoids, flavonoids, phenolic compounds, and tannins) of Argemone mexicana L., Ipomoea carnea Jacq. subsp. Fistulosa (Martius ex Choisy), Amorimia rigida (A.Juss.) W. R. Anderson, Ricinus communis L. and Syzygium aromaticum (L.) Merr. & L. M. Perry using UV-VIS spectroscopy, and evaluating the bioactivity of the ethanolic extracts on citrus blackfly eggs (Aleurocanthus woglumi Ashby, 1915). Pera sweet orange leaves infested with citrus blackfly eggs were treated by immersion in 0.5, 1.0, 5.0, and 10%; each replicate consisted of 30 eggs. The experimental design was completely randomized, with seven treatments and four replications. Three immersions of leaves with eggs were performed, and the mortality was evaluated seven days after the procedure. Leaves were placed in Petri dishes and kept in incubators [25±1°C; relative humidity (RH) 60±5% and 12 hours]. S. aromaticum peduncle presented high content of tannins and phenolic compounds, while R. communis leaves showed high content of phenolic compounds. The commercial product Bioneem © caused egg infeasibility greater than 85% at all concentrations. Treatments (10%) that caused the greatest egg mortality were Bioneem © (94.74%), R. communis extract (81.58%), and the extract of S. aromaticum peduncle (80.57%). RESUMO: Os principais objetivos deste estudo foram determinar, utilizando espectroscopia UV-VIS, os compostos secundários (carotenoides, flavonoides, compostos fenólicos e taninos) das espéciesArgenome mexicana L., Ipomoea carnea Jacq. subsp. Fistulosa (Martius ex Choisy), Amorimia rigida (A.Juss.) W. R. Anderson, Ricinus communis L. e Syzygium aromaticum L. (L.) Merr. & L. M. Perry, bem como avaliar a bioatividade de extratos etanólicos sobre ovos da mosca -negra-dos-citros (Aleurocanthus woglumi Ashby, 1915). Folhas de laranja Pêra infestadas com mosca-negra-dos-citros foram imersas nos tratamentos, a 0,5%, 1,0%, 5,0% e 10% de concentração; cada replicata foi constituída por 30 ovos. O delineamento foi inteiramente casualizado, sete tratamentos e quatro repetições. Foram realizadas três imersões das folhas com ovos, tendo sido avaliada a mortalidade sete dias após as imersões. As folhas foram alocadas em placa de Petri e mantidas em câmaras climáticas (25±1°C; U.R 60±5% e 12 horas). O pedúnculo do craveiro-da-india apresentou alto teor de taninos e compostos fenólicos, e folhas de mamona apresentavam alto teor de compostos fenólicos. O produto comercial Bioneem © , em todas as concentrações, causou inviabilidade de ovos superior a 85%. Os tratamentos (10%) que causaram a maior inviabilidade de ovos foram o Bioneem © (94,74%), o extrato de mamona (81,58%) e o extrato do pedúnculo do craveiro-da-india (80,57%).
