“…Brazilian mahogany (Swietenia macrophylla King) is the most commercially valuable Meliaceae species in the international timber market and one of the most exploited plant species in Brazil (SANTOS et al, 2008a). However, mahogany monoculture is jeopardized by severe pest attacks, which limit tree growth and cause excessive damage and plant death (ROCHA; QUOIRIN, 2004).…”

Few research on the entomofauna associated to forest plantations with Swietenia macrophylla (King) in Brazil has been reported. The aim of this study was to analyze the Coleoptera communities in forest ecosystems with S. macrophylla, Brazilian mahogany, with emphasis on the diversity of families and the main functional groups. The insects were collected through pitfall traps in three forest ecosystems: monoculture, consortium and forest enriched with Brazilian mahogany, during dry and rainy periods in two consecutive years. The identification of the captured insects occurred in the entomology laboratory of the Federal Rural University of Amazonia. The analysis was performed through Past Paleontological Statistic 3.14 and ANAFAU, where the difference was considered significant only when p ? 0.05. 11,358 specimens from 21 families were captured, of which 8,058 were sampled in the rainy season and 3,299 in the dry season. There was influence of seasonality and types of forest ecosystems during collection. The families Nitidulidae, Staphylinidae, Carabidae and Meloidae presented greater abundance and richness in the complex ecosystems. Anobiidae, Cerambycidae, Bostrichidae, Brentidae, Buprestidae, Curculionidae, Elateridae, Chrysomelidae and Lagriidae were considered to be pests and common to all studied ecosystems; however, the families Nitidulidae, Scarabaeidae, Tenebrionidae and Passalidae had the function of decomposers; Carabidae, Coccinellidae, Histeridae, Meloidae, Staphylinidae, Cantharidae and Hydrophilidae were the predators.

Azadirachta indica A. Juss, popularly known as neem, is a species native to India, belonging to family Meliaceae, considered the most important plant species with insecticidal action. The aim of this study was to evaluate the influence of growth regulators on induction and growth of neem callus and to observe their viability for embryogenesis through morpho-histological characteristics. In vitro germinated plants were used for excision of nodal explants. These segments were inoculated in Murashige and Skoog culture medium containing 1.0 mg/l 2,4-D (2,4-dichlorophenoxyacetic) combined with BAP (6-benzylaminopurine) at the following concentrations: 0.0, 0.5, 1.0 and 2.0 mg/l (T1, T2, T3 and T4 respectively), for callus induction. At 0 (mass of nodal segments without callus), 20, 40 and 60 days of culture, the percentage of callus formation was observed and the callus weight was measured for each treatment and at the end of the 60 days, consistency, color, and cell histology were evaluated. There was callus formation in all treatments tested. The highest induction of Azadirachta indica A. Juss callus is observed in the presence of 1.0 mg/l 2,4-D + 2.0 mg/l BAP, with callus showing light brown color, friable consistency and rounded cells with intense cell division, typical of cells with potential embryogenic capacity.

“…Quisen (2007) obtained calli from Eucalyptus globulus in the dark after a 30-days exposure followed by transference to light for 30 more days, but different cytokines (BAP, TDZ, KIN) and auxins (NAA, 2,4-D, picloran) combinations did not influence calli formation. Rocha & Quoirin (2004), on the other hand, induced calli in mahohany explants with BAP + NAA.…”

The cultivation of calli and cell suspension lines of aromatic plants is important because they are considered to be factories of active compounds such as, for instance, the rosmarinic acid found in Lavandula species. L. angustifolia is considered the most important species because it is regarded to be practically free from camphor, differently from other species in the genus, however, it is less productive than L. dentata, which is very productive and easily asexually propagated, but presents higher content of camphor. Information about calli and cell suspensions induction and maintenance for Lavandula species, especially the latter, is scarce. Not only that, but once callus formation is induced, it is necessary to identify the growth dynamic of the cells in order to maintain healthy, logarithmically phased growing cells for future elicitation. The goals of this work were to induce calli formation, evaluate growth curve and produce cell suspensions of Lavandula angustifolia and Lavandula dentata, two Lavandula species of great economical importance. Apical and lateral buds of L. angustifolia and L. dentata were placed on MS + 1 mg.L -1 2.4-D or picloran + 0.5 mg.L -1 BAP or 1 mg.L -1 2.4-D + 0.5 mg.L -1 GA 3 , in the presence of light or in the dark. Calli were obtained only from L. angustifolia, under light, with the combination of 2.4-D + GA 3 . The growth curve of L. angusifolia calli indicated the need for media exchange every three weeks. A blue pigment which may be interesting as a dye in the food industry was present in the media. Cells suspensions were formed.Key words: Growth regulator, lavender, micropropagation, tissue culture. Calogênese, curva de crescimento de calos e formação de suspensões celulares de Lavandula RESUMO O cultivo de calos e suspensões celulares de plantas aromáticas é importante porque estes são considerados fábricas de compostos ativos como, por exemplo, o ácido rosmarínico encontrado em espécies de Lavandula. L. angustifolia é considerada a espécie mais importante por ser praticamente livre de cânfora, todavia, é menos produtiva que L. dentata, que é facilmente propagada vegetativamente, mas apresenta alto teor de cânfora. Informação sobre indução e manutenção de calos e suspensões celulares de espécies de Lavandula, especialmente a última, é escassa. Não somente isto, mas uma vez que a formação de calos é induzida, é necessário identificar o crescimento dinâmico das células para mantê-las com crescimento saudável, em fase logarítmica para futuras elicitações. Os alvos deste trabalho foram indução de calos, avaliação de curva de crescimento e formação de suspensões celulares de Lavandula angustifolia e Lavandula dentata, duas espécies de Lavandula de grande importância econômica. Gemas de L. angustifolia e L. dentata foram colocadas em MS + 1 mg.L -1 2,4-D ou picloran + 0,5 mg.L -1 BAP ou 1 mg.L -1 2,4-D + 0,5 mg.L -1 GA 3 , em condições de luz, ou no escuro. Foram obtidos calos de L. angustifolia em condições de luz, sendo 2,4-D + GA 3 a melhor combinação. A curva de cr...
