First record of Duponchelia fovealis (Lepidoptera: Crambidae) in South America

Abstract

ABSTRACT

Trichogramma galloi and Trichogramma pretiosum for the management of Duponchelia fovealis (Lepidoptera: Crambidae) in strawberry plants

“…Duponchelia fovealis Zeller (Lepidoptera: Crambidae), popularly known in Brazil as the strawberry caterpillar (Paes et al, 2015), is a polyphagous pest with several reported botanical species as hosts (Bonsignore & Vacante, 2010;Franco & Baptista, 2010). Recently introduced in Brazil, D. fovealis has been establishing itself in strawberry fields (Fragaria x ananassa), causing large losses (Zawadneak et al, 2016).…”

“…Duponchelia fovealis Zeller (Lepidoptera: Crambidae), popularly known in Brazil as the strawberry caterpillar (Paes et al, 2015), is a polyphagous pest with several reported botanical species as hosts (Bonsignore & Vacante, 2010;Franco & Baptista, 2010). Recently introduced in Brazil, D. fovealis has been establishing itself in strawberry fields (Fragaria x ananassa), causing large losses (Zawadneak et al, 2016).Biological control by the release of parasitoids of the genus Trichogramma (Hymenoptera: Trichogrammatidae) has shown promise for controlling agriculture and forestry insect pests before they damage the crop (Pratissoli et al, 2007). Moreover, this control is favored because of Trichogramma parasitism on many lepidopteran species (Pizzol et al., 2010).…”

Biological parameters of Duponchelia fovealis (Lepidoptera: Crambidae) reared in the laboratory on two diets

“…Thus, biological control may provide an alternative way of managing D. fovealis (Zawadneak et al, 2016). However, in the development of a biological control program of any agricultural pest, the fi rst step is to obtain a good understanding of the basic biology of the target species and how it can be effi ciently reared in the laboratory (Sørensen et al, 2012).…”

“…Given the recent history of D. fovealis as a nonnative pest and the signifi cant damage it causes (Zawadneak et al, 2016), lack of pest control can have serious economic implications. Thus, biological control may provide an alternative way of managing D. fovealis (Zawadneak et al, 2016).…”

“…This insect is a pest of strawberry in Portugal, Italy, France, Brazil and Turkey (Bonsignore & Vacante, 2010;Franco & Baptista, 2010;Zawadneak et al, 2011Zawadneak et al, , 2016Efi l et al, 2014).…”
