1. Conjoint effect of oil-seed cakes and Pseudomonas fluorescens on the growth of chickpea in relation to the management of plant-parasitic nematodes
Soil application of organics has been explored as an alternative means of organic management of plant-parasitic nematodes. Efficiency of different oil-seed cakes of neem (Azadirachta indica), castor (Ricinus communis), groundnut (Arachis hypogaea), linseed (Linum usitatissimum), sunflower (Helianthus annuus) and soybean (Glycine max) were evaluated in field

2. Toxicity of neem's oil, a potential biocide against the invasive mussel Limnoperna fortunei (Dunker 1857)
O Mexilhão dourado Limnoperna fortunei (Dunker 1857) é uma das espécies invasoras melhor distribuídas na América do Sul, sendo motivo de grande preocupação para a indústria local. Neste estudo, nós realizamos ensaios de toxicidade de soluções de Óleo de Neem em larvas e adultos bentônicos de L. fortune (7, 13 e 19 ± 1 mm). Com o objetivo de ava

3. Effect of PONNEEM# on Spodoptera litura (Fab.) and its compatibility with Trichogramma chilonis Ishii
Antifeedant and growth regulating activities of PONNEEM, an oil formulation containing neem and pungam (karanj) oils were evaluated along with individual neem and karanj oils and Nimbicidine, a commercial neem-based pesticide against fourth instar larvae of Spodoptera litura (Fab.). Among all the treatments, PONNEEM recorded the maximum antifeedant activity

4. O extrato de neem (Azadirachta indica) causa alterações no desenvolvimento ninfal, no aparelho reprodutor e sistema digestivo do predador Supputius cincticeps (Heteroptera: Pentatomidae)? / Does the neem (Azadirachta indica) extract cause nymphal development, the reproductive system and digestive tract of the predator Supputius cincticeps (Heteroptera: Pentatomidae)?
The subfamily Asopinae presents important species of predators, as Supputius cincticeps (Stal) (Hemiptera: Pentatomidae). These stinkbug present potential for the biological control of Lepidoptera defoliators in eucalyptus plantations in Brazil.Botanical insecticides, mainly neem (Azadirachta indica), are alternative for the control of herbivore insects of a

5. The neem [Azadirachta indica a: juss (meliaceae)] oil reduction in the in vitro production of zearalenone by Fusarium graminearum
Zearalenone, a mycotoxin produced by fungi of the genus Fusarium, including F. graminearum, triggers reproduction disorders in certain animals and hyperestrogen syndromes in humans. Current research investigates three concentrations of neem oil extract (0.1, 0.25 and 0.5%) in reducing the production of zearalenone. Neem oil extract decreased zearalenone amou

6. Toxicity of neem oil to Bemisia tabaci biotype B nymphs reared on dry bean.
The objective of this work was to determine the most susceptible nymphal stage of Bemisia tabaci biotype B to neem (Azadirachta indica A. Juss.) oil applied to dry bean (Phaseolus vulgaris L.) in a screenhouse. A solution of commercial oil (Dalneem) extracted from neem seeds was sprayed directly on each nymphal instar at 0, 0.1, 0.25, 0.5, 1 and 2% conce

7. Neem oil antifeedant and insecticidal effects on Oebalus poecilus (Hemiptera: pentatomidae) males and females.
Avaliou-se o efeito das formulações comerciais de óleo de nim (Azadirachta indica) Dalneem e Nim-I-Go sobre a alimentação e sobrevivência de O. poecilus, em arroz irrigado. O efeito sobre a alimentação foi avaliado nas concentrações de 1% e 2% (v/v) das formulações. O efeito inseticida foi avaliado nas concentrações de 0,5%; 1%; 2%; e 4% (v/v)

8. Toxicity of neem oil to Bemisia tabaci biotype B nymphs reared on dry bean.
O objetivo deste trabalho foi determinar o estágio ninfal de Bemisia tabaci biótipo B mais suscetível ao óleo de nim (Azadirachta indica A. Juss.) aplicado em feijoeiro (Phaseolus vulgaris L.), em casa telada. Foram avaliados o tempo letal (TL) e concentração letal (CL) do óleo comercial de sementes de nim Dalneem. Para CL, concentrações de 0, 0,1,

9. Synthesis of biodiesel from Neem oil using sulfated zirconia via tranesterification
Sulfated zirconia (SZ) is a widely used catalyst, which is synthesized by a solvent free method and the synthesized catalyst has been characterized. Neem Methyl Ester (Biodiesel) was prepared by a two-step process of esterification and transesterification from Neem oil with methanol in the presence of catalyst. Acid catalyst was used for the esterification a

10. Selectivity of neem to Trichogramma pretiosum Riley and Trichogrammatoidea annulata De Santis (Hymenoptera: Trichogrammatidae)
Trichogramma pretiosum Riley and Trichogrammatoidea annulata De Santis are commonly found in avocado and persimmon orchards in northern Parana state. However, their abundance depends on whether insecticides are used or not to control the key lepidopteran pests Stenoma catenifer (Wals.)

12. Uso de CLAE no controle de qualidade em produtos comerciais de Nim: reprodutibilidade da ação inseticida
The Neem tree, Azadirachta indica, provides many useful compounds that are used as pesticides. However, the efficiency in field of products like neem oil can be committed because they have not been observed reproductive content of secondary metabolic like azadirachtin. Based on reverse-phase high-performance liquid chromatography (HPLC) a new method was deve
