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
