The Ecology of Heliothis Species in Relation to Agroecosystems

Ocorrência da lagarta-da-maçã-do-algodoeiro em frutos de tomateiro no estado do Espírito Santo

“…Heliothis virescens (Fabricius) é praga que tem sido relatada alimentandose de diversas culturas no norte e sul do continente americano (Fitt, 1989 m e temperatura média anual de 22,2ºC), onde havia, na época da ocorrência, apenas café e pastagem nas regiões adjacentes.…”

Attractiveness and non-preference of soybean cultivars to Heliothis virescens (Lepidoptera: Noctuidae) feeding

“…The tobacco budworm, Heliothis virescens (Fabricius 1781), is a defoliating caterpillar that damages soybean crops at all stages of crop development, feeding on pods and flower buds, promoting defoliation, and reducing the plant photosynthetic rate and consequently the crop yield (Tomquelski and Maruyama, 2009;Bueno et al 2013;Owen et al, 2013). The main host of this pest is cotton (Gossypium hirsutum L.), but because of its polyphagous feeding behavior, this pest also feeds on tomato, sunflower, bean, and tobacco (Fitt, 1989;Pratissoli et al, 2006;Karpinski et al, 2014). This insect is a facultative migratory pest that can fly long distances in search of its host plants (Farrow and Daly, 1987).…”

Genetic diversity and susceptibility to Vip3Aa20 protein in Brazilian populations of <i>Helicoverpa armigera</i> and <i>Helicoverpa zea</i> (Lepidoptera: Noctuidae)

“…Therefore, the sustainable management of H. armigera will likely become a significant challenge for Brazilian entomology in the coming years, especially considering the polyphagous feeding habit, the great dispersal ability, and the numerous reports of resistance to insecticides and Bt crops for this insect (FITT, 1989;NIBOUCHE et al, 1998;MARTIN et al, 2000;GUNNING et al, 2005;ZHANG et al, 2009;ACHALEKE;BRÉVAULT, 2010;NAIR et al, 2013). This scenario requires immediate attention, as there is an imminent risk of H. armigera expanding throughout the American territory and perhaps reaching agricultural areas in Central and North America.…”

“…The two Heliothinae pests, Helicoverpa armigera (Hübner) and Helicoverpa zea (Boddie) (Lepidoptera: Noctuidae), are important pests due to their high polyphagy, high dispersal and rapid adaptation to various control tactics (FITT, 1989;HEAD et al, 2010;EDWARDS et al, 2013;YANG;WU, 2013;RAZMJOU;NASERI;HEMATI, 2014;WALSH et al, 2014). H. zea is endemic in the Americas, while H. armigera were found only in the Old World until it was first detected in Brazil in 2013 (CZEPAK et al, 2013;TAY et al, 2013).…”

“…armigera is considered to be one of the most important agricultural pests in the world. This insect is widely distributed throughout Asia, Africa, Europe, and Australia, and it has been shown to attack more than 100 host species from 45 different plant families (FITT, 1989;POGUE, 2004;WU et al, 2008). In contrast, H.…”
