Resumen:
The
toxicity of essential oils from the citrus peel has been proposed as
the major resistance mechanism offered
by citrus
to fruit fly
infestation. We evaluated the insecticidal activity of the ether
extracts from the lemon (Citrus
limon [L.]
Burm.) and grapefruit (C.
paradisi Macfadyen)
peel as well as from limonene and citral against Anastrepha
fraterculus (Wiedemann)
and Ceratitis
capitata (Wiedemann)
immature stages. We also evaluated the toxicity of the extracts at
two ripening stages. Extracts proved toxic to A.
f raterculus egg
and larvae. The lemon and grapefruit extracts showed the same
toxicity in both fruit fly
species. For A.
f raterculus eggs,
citral was more toxic than limonene; for larvae, they showed equal
toxicity. Anastrepha
f raterculus eggs
were more sensitive than C.
capitata eggs.
In conclusion, we provide evidence of chemical resistance mechanisms
that could account for the nonhost condition of lemon for A.
f raterculus.
