“…Since then, H. armigera has been reported from countries neighbouring Uruguay; including Paraguay (Senave, 2013), Argentina (Murúa et al, 2014;Arneodo et al, 2015), and Bolivia (Kriticos et al, 2015). Kriticos et al (2015) modeled the anticipated spread of H. armigera across the southern and northern American continents.…”

ABSTRACT. Since its detection in Brazil in 2013, the Old World cotton bollworm Helicoverpa armigera has been reported in Argentina, Paraguay, and Bolivia. Here we present evidence extending the South American range of H. armigera to Uruguay, using polymerase chain reaction and sequencing of the partial mitochondrial DNA (mtDNA) cytochrome oxidase I region. Molecular characterization of this gene region from individuals from Paraguay also supports previous morphological identification of H. armigera in Paraguay. Shared mtDNA haplotypes in H. armigera from Brazil, Uruguay, and Paraguay were identified. Additional surveying of populations in this region will be imperative to better monitor and understand factors that are underpinning its presence and successful adaptation in these South American regions. We discuss our findings with respect to the development of resistance pest management strategies of this invasive insect pest in a predominantly monoculture soybean crop landscape in the Southern Cone region.

“…Em 2013 foi relatada pela primeira vez nas Américas, no Brasil, nos estados de Goiás, Mato Grosso, Bahia e Paraná (Czepak et al, 2013;Specht et al, 2013;Tay et al, 2013); antes disso, era considerada praga quarentenária. Poucos meses depois foi registrada no Paraguai (Senave..., 2013) e Argentina (Murúa et al, 2014). Cunningham & Zalucki (2014) As lagartas de H. armigera atacam tanto estruturas vegetativas quanto reprodutivas de seus hospedeiros, como cotilédones, folhas, flores e frutos (Johnson & Zalucki, 2005).…”

Control of Helicoverpa armigera (Lepidoptera: Noctuidae) in soybean with chemical and biological insecticidesAbstract -The objective of this work was to evaluate the performance of insecticides authorized on an emergency basis to control of Helicoverpa armigera (Lepidoptera: Noctuidae) in soybean. Seven insecticides were sprayed on the field and, 24 hours after that, soybean pointer leaves were collected and offered to 2 nd instar larvae in the laboratory. Fourth instar larvae received the last trifoliate leaf that was fully expanded at the time of spraying. Another larvae group was exposed to leaves collected from 72 hours onwards after spraying. In the field, six insecticides were sprayed, and then the plants were infested with 2 nd and 3 rd instar larvae. In the first study, flubendiamide, chlorantraniliprole, chlorfenapyr, indoxacarb, and methoxyfenozide caused 100% mortality of the 4 th instar, eight days after the beginning of exposure, while baculovirus and Bacillus thuringiensis (Bt) caused 60-75% mortality, which reached 88-90% at the end of the pupal stage. For 2 nd instar larvae, only flubendiamide and chlorantraniliprole caused 100% mortality. Flubendiamide, chlorantraniliprole, and chlorfenapyr showed the lowest lethal time for the 4 th instar, and flubendiamide and chlorantraniliprole for the 2 nd instar. Seventy-two hours after spraying, the performance of insecticides was not satisfactory. In the field, there was satisfactory efficiency of flubendiamide, spinosad, baculovirus, and Bt on 2 nd and 3 rd instar larvae.

In Brazil, the caterpillar Helicoverpa armigera (Hübner) is a key economic pest of soybean, from seedling emergence to the reproductive stage. Control of this pest has relied on foliar insecticide sprays, and the use of insect-resistant cultivars. Characterization of the efficacy of insecticides that can be used for seed treatment, as a complement or alternative control for this pest, is needed for the production sector. The study objective was to evaluate the insecticidal potential of diamides for control of H. armigera larvae, when applied to soybean seeds. The effects of seed treatment with cyantraniliprole or chlorantraniliprole on 1st-and 3rd-instar H. armigera larvae, in both conventional and in "Bt soybean" (Cry1Ac), were evaluated under laboratory conditions. Two infestations were carried out at 8, 13 and 21 days after plant emergence, to determine the leaf area consumed, and mortality of larvae. The insecticides cyantraniliprole and chlorantraniliprole, used at rate of 60 and 62.5 g a.i./100 kg seeds, respectively, have potential for the control of 1st-instar H. armigera larvae up until at 13 days after the emergence of soybeans plants. The Cry1Ac protein controlled both 1st-and 3rd-instar H. armigera larvae at least until 21 days after plants emergence.
