Abstract
The tomato borer Tuta absoluta, native to western South America, is an
extremely devastating pest in tomato crops in most of South America,
Europe and Africa North of the Sahel, causes yield losses up to 100% and
decreases fruit quality in open field and greenhouse crops if control meth-
ods are not applied. In Brazil two other important lepidopteran pests –
Neoleucinodes elegantalis and Helicoverpa zea – occur in tomato, as well as
thrips, whiteflies and aphids. For control of these pests, frequent applica-
tions of pesticides of up to 5 times per week are needed, and these resulted
in the appearance of resistant populations to a number of active ingredi-
ents and decimation of natural enemies. Biological control may offer a
better, safer and more sustainable opportunity for pest management.
Mirid predatory bugs are currently used with success in southern Europe
to control T. absoluta and other pests. In Brazil, four Hemipteran predatory
bugs, not yet known to attack T. absoluta, were found to successfully prey
on eggs and larvae of this pest. The first results on their predation capacity,
development, survival and reproduction on T. absoluta on tomato plants
are presented.
Introduction
Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae),
the South American tomato pinworm or tomato
borer, a key pest of tomato and native to the western
part of South America, invaded Brazil around 1980
(Souza and Reis 1992) and Europe in 2006 (Desneux
et al. 2010). T. absoluta is an extremely devastating
pest in tomato crops in South America, Europe and
Africa North of the Sahel (Desneux et al. 2010). How-
ever, due to successful biological control, the pest can
be very well managed in Europe (Urbaneja et al.
2012). Without control methods, this pest causes yield
losses up to 100% and decreases fruit quality in both
field and in greenhouse tomato crops (Guilardo ´n
et al. 2001; Desneux et al. 2010). In Brazil, two other
important lepidopteran pests occur in tomato: the
tomato fruit borer, Neoleucinodes elegantalis (Guenee)
(Lepidoptera: Crambidae) and tomato fruitworm
Helicoverpa zea (Boddie) (Lepidoptera: Noctuidae). In
addition to these lepidopteran pests, also thrips,
whiteflies, aphids and mites are problematic tomato
pests.
Tomato is a very important vegetable crop in Brazil
with a production of 4.2 million tons on an area of
almost 65 000 hectares in 2010 (Agrianual 2011). The
consequence of the problematic pest situation in
Brazilian tomato production – many different pests
and, due to the warm climate, a fast development of
pest populations – is that a high frequency of insecti-
cide sprays is needed to be able to harvest tomatoes:
insecticide spray frequencies can be up to 5 times per
week and 36 times per production cycle of 12 weeks
(Guedes and Picanco 2011). Thus, development of
resistance to these insecticides is usually fast (Siqueira
et al. 2000), resulting in ineffectiveness and a decima-
tion of natural enemy species of the various pest
organism, as well as in high pesticide residue levels on
