Acetogenins, a class of natural compounds produced by some Annonaceae
species, are potent inhibitors of mitochondrial electron transport systems. Although the
cellular respiration processes are an important biochemical site for the acaricidal action of
compounds, few studies have been performed to assess the bioactivity of acetogenin-based
biopesticides on spider mites, mainly against species that occur in orchards. Using
residual contact bioassays, this study aimed to evaluate the bioactivity of an ethanolic
extract from Annona mucosa seeds (ESAM) (Annonaceae) against the citrus red mite
Panonychus citri (McGregor) (Acari: Tetranychidae), an important pest of the Brazilian
citriculture. ESAM is a homemade biopesticide which was previously characterized by its
high concentration of acetogenins. It caused both high mortality of P. citri females
(LC50 = 7,295, 4,662, 3,463, and 2,608 mg l-1, after 48, 72, 96, and 120 h of exposure,
respectively) and significant oviposition deterrence (EC50 = 3.194,80 mg l-1). However,
there was no effect on P. citri female fertility (hatching rate). In addition, the ESAM
efficacy (in terms of its LC90) was compared with commercial acaricides/insecticides (at
its recommended rate) of both natural [Anosom 1 EC (annonin), Derisom 2 EC (karanjin),
and Azamax 1.2 EC (azadirachtin ? 3-tigloylazadirachtol)] and synthetic origin
[Envidor 24 SC (spirodiclofen)]. Based on all of the analyzed variables, the ESAM
exhibited levels of activity superior to other botanical commercial acaricides and similar
to spirodiclofen. Thus, our results indicate that ESAM may constitute a biorational
acaricide for citrus red mite integrated pest management in Brazilian citrus orchards,
particularly for local use. MenosAcetogenins, a class of natural compounds produced by some Annonaceae

O custo de producao de feijao-de-vagem, em Santa Catarina, e considerado muito elevado em razao, principalmente, da mao-de obra e fertilizantes, responsaveis por 62% do custo total da lavoura. Objetivou-se neste trabalho, determinar o efeito residual da adubacao mineral e organica utilizada no tomateiro sobre o rendimento do feijao-de-vagem, em cultivo sucessivo. Os tratamentos de adubacao residual consistiram na combinacao de doses crescentes de N (30;60;120 e 180kg/ha de N), P (75;150;300 e 450kg/ha de P2 05), K (30;60;120;e180kg/ha de K20) e estrume de galinha (0,10 e 20t/ha). A semeadura do feijao-de-vagem, cultivar macarrao favorito Ag-480, foi feita em 10/09/86, com 2 plantas/cova, em sistema estaleirado anteriormente utilizado para o tomateiro. O rendimento de vagens mostrou estreito relacionamento com os teores de fosforo residual no solo e adubacao organica, tendo as doses de 60kd/ha de N + 150kg/ha de P2 O5 + 60kg/ha de K2 0 + 20t/ha de cama de aviario feita na cultura do tomate, proporcionando a mais alta producao de vagens. |
