In 2013, the presence of Helicoverpa armigera (Hübner) was reported in cotton, soybean, corn and weeds in diverse regions of Brazil. We studied the biology and the fertility life table of this pest when reared on cotton (293 cv. CNPA RF), soybean (cv. Brasmax Power), corn (cv. BRS 1010), wheat (cv. BR 18) and on an artificial diet. Caterpillars were reared using the vegetative and reproductive structures of the hosts, under laboratory conditions (temperature 25 ± 1°C; relative humidity (RH) 70 ± 10%; photoperiod =14 h). The experimental design was completely randomized, with five treatments (four host plants and artificial diet) and 17 replications. Significant effects were verified for the different types of hosts tested on the growth of the insect as well as on fecundity and laying rate. The results showed that cotton and soybean had higher viability at the stages of growth, higher rate of survival of adult females in the reproductive period than the other host crops, and similar values for insects reared on an artificial diet, which reveals that cotton and soybean can be appropriate for rearing H. armigera on a natural diet. Corn and wheat showed high larval and pupal mortality and low biotic potential.

“…Plants that are in flower, hairy and tall are more attractive for oviposition (Sullivan and Molet, 2014). During the oviposition period, which lasts 5-24 days, a female can lay over 3 000 eggs (CABI and EPPO, 1990), but 700-2 200 is the average total fecundity rate observed from females emerging from larvae feeding on different hosts (Razmjou et al, 2014). Eggs hatch in about three days at 25 °C, but take up to 11 days at lower temperatures (Venette et al, 2003).…”

“…Adults are nocturnal and, depending on food, pupal weight, temperature and activity, can live for up to 20 days (for males) and 18 days (for females) under laboratory conditions (Razmjou et al, 2014). Females emerge one to two weeks before males (Izquierdo and Millan, 1994).…”

The Panel on Plant Health undertook a pest categorisation of Helicoverpa armigera for the European Union territory. The taxonomy of H. armigera and related species worldwide is complex but, in Europe, only H. armigera is present. Although it has been recorded in all Member States, it persists throughout the year only in the southernmost parts of Europe where winters are not too cold. From these areas and from North Africa, longdistance northward migrations of up to 1 000 km can occur. In most of Europe, only transient populations are found outdoors. Nevertheless, damage to outdoor crops has been recorded as far north as the Netherlands. H. armigera also damages crops produced under protected conditions, with outbreaks related to the import of plants for planting. It is highly polyphagous, with over 180 host species recorded from more than 45 families, and it is particularly hard to detect and difficult to control because the larvae bore into reproductive structures with few visible external symptoms. Damage is especially severe in hot summers. Insecticide resistance is common and a wide range of insecticides may be applied. It is listed in Annex IIAII, and special requirements for H. armigera are formulated in Annexes IVAI and IVAII of Council Directive 2000/29/EC to regulate the movement of plants for planting of Solanaceae and three ornamental genera.

“…Although the exact evolutionary relationship between H. armigera and H. zea is uncertain, they are considered "twin" or "sibling" species, and are able to mate and produce fertile offspring under laboratory conditions (Laster and Hardee, 1995;Laster and Sheng, 1995;Cho et al, 2008, Pogue, 2013. Both H. armigera and H. zea are highly polyphagous and have high reproductive and dispersal capacities that favor their rapid adaptation to various control tactics (e.g., insecticides and genetically modified plants) (Fitt, 1989;Head et al, 2010;Yang et al, 2013;Razmjou et al, 2014;Walsh et al, 2014). Due to the invasion of H. armigera, both species now coexist in Brazilian landscapes.…”

ABSTRACT. The Old World bollworm Helicoverpa armigera (Hübner) was recently discovered in Brazil. This species is closely related to the New World bollworm H. zea (Boddie), and mating between these species has already been reported under laboratory conditions. Here, we tested the cross-species amplification of 20 microsatellite (SSR) loci in field populations of H. armigera and H. zea collected from Brazilian cropping systems. Seven SSR loci were successfully amplified and polymorphic in both species except for the locus HaC14, which was monomorphic for H. zea. All SSR loci were in linkage equilibrium, and deviations from HardyWeinberg equilibrium were only observed for the locus HarSSR1 in the HaRS-2 population, where null alleles were present. A moderate level of polymorphism was detected in H. armigera and H. zea populations with a mean allele number of 4.14, and 2.24, respectively. Interestingly, most of the populations of the recent invader H. armigera showed higher genetic diversity and inbreeding coefficients than H. zea populations. The genetic identity of each species was recovered using a STRUCTURE analysis, where the populations formed two clusters (K = 2) according to their species. STRUCTURE also suggested the occurrence of potential hybrid offspring between H. armigera and H. zea individuals in natural conditions. These SSR loci will be valuable in characterizing population differentiation, invasion routes, adaptation, reproductive behavior, and intra-and interspecific gene flow in H. armigera and H. zea populations in Brazil, the USA, and other areas where these two pests occur.
