Growth disruption, abnormalities and mortality of Spodoptera littoralis (Boisduval) (Lepidoptera: Noctuidae) caused by Azadirachtin

Abstract: Redução do Crescimento, Deformidades e Mortalidade de Spodoptera littoralis (Boisduval) (Lepidoptera: Noctuidae) Causadas por Azadiractina RESUMO -A azadiractina é o composto mais eficiente extraído da planta Azadirachta indica A. Juss, com propriedades insecticidas e que afetam o crescimento de diversas espécies de insetos. Seus efeitos no desenvolvimento e na sobrevivência de Spodoptora littoralis (Boisduval) foram estudados em condições de laboratório. Larvas de terceiro ínstar foram aliementada individua… Show more

“…Similarly, Bogorni and Vendramim (2003) where neem seed extracts and T. pallens leaves were used. Growth inhibition and poor weight gain can be attributed to reduced feeding and impaired ability to convert nutrients into biomolecules to form the tissues of insects, preventing growth and weight gain (Martinez and Emden, 2001). For Tanzubil and McCaffery (1990), significant weight reduction caused by the extracts indicates that the insects, in need of degrading possible secondary metabolites present in the extracts, can be diverted for this purpose, resources that would be used to gain biomass.…”

“…Os efeitos da azadiractina sobre insetos incluem repelência, deterrência alimentar, interrupção do crescimento, interferência na metamorfose, esterilidade e anormalidades anatômicas (Mordue & Nisbet 2000, Martinez & Emden 2001, Ve nzon et al 2007, Santos et al 2004.…”

“…Os dados de mortalidade média foram analisados mediante análise de variância (ANOVA ), utilizando o Proc ANOVA do SAS (SAS Institute 1999-2001, e as médias comparadas pelo teste de Tukey a 5% de probabilidade quando significativo, sendo os dados transformados para √ (x + 0,5).…”

“…Juss., como alternativa ao controle químico de diversos insetos-praga (MAR-TINEZ, 2002). Dessa espécie tem sido extraída a azadiractina, que possui propriedades inseticidas, afetando diversas espécies de insetos, cujos extratos têm-se revelado tão potentes quanto os inseticidas comerciais (SCHMUTTERER, 1988;SCHMUT-TERER, 1990; MARTINEZ; VAN ENDEM, 2001).…”
