“…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). Essa espécie apresenta ampla capacidade de dispersão (Farrow & Daly, 1987), pode migrar para uma distância de até 1.000 km (Pedgley, 1985), consegue sobreviver em condições adversas (Karim, 2000;Mironidis et al, 2010) e tem alto potencial reprodutivo (Naseri et al, 2009a(Naseri et al, , 2009b. Tais características, associadas à ampla distribuição geográfica e diversidade de plantas hospedeiras, possibilitam elevada capacidade de disseminação e têm contribuído para sua rápida adaptação às diversas regiões agrícolas brasileiras, oferecendo riscos para diferentes sistemas produtivos.…”

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.

“…The cotton bollworms used to appear also in the Central-Europian Region; they even did appear in larger numbers in Hungary every [16][17] th year due to their gradation in the primary distribution areas. This pest cannot overwinter in Hungary due to low winter temperatures and frost (Udwardy 1983;Farrow & Daly 1987). An unexpected presence of larger numbers was observed all over the country from 1993 until present (Szeőke 1994;Szeőke & Vörös 2001).…”

To determine the cotton bollworm migrating population rate in Hungary, we examined the weights and the front wing morphological feautures of trapped moths. We used sex pheromone traps to monitor field populations during the maize vegetation cycle period in 2008. We examined moths trapped at various times, and measured their body mass (m) and morphological features, namely the front wing quotient (fWQ = quotient of length of front wing/width of front wing), modified wing loading (WL = weight of moth/surface of front wing), and the relative thorax size (RTS = width of thorax/width of head). The data were analysed by Student t-test, anterior wing abrasion and darkness were analysed by a Adobe Photoshop 7.0 software. The Hungarian appearance of three cottom bollworm generations in 2008 was also observed. Based on the examined morphological features we found regularity in body mass, front wing quotient and modified wing loading changes during the flight period. The specimens trapped in the first and third part of the flight period had lower body mass, larger wing surface, longer wings and more favourable modified wing loading than the specimens trapped in the middle of the flight period. The abrasion and colour of the anterior wings of cotton bollworms were concordant to morphometric investigations. The abrasion in darker spots E1 and E3 clearly showed a more intensive usage of the wings in case of specimens trapped at the beginning and at the end of the flight period.

“…Some control measures are focused on avoiding or at least revealing the migratory routes of these species (Riley & Reynolds, 1983;Farrow & Daly, 1987;Riley & Reynolds, 1990;Pedgley, 1993;Chapman et al, 2010). Oedalus senegalensis is a pest species that can migrate up to 350 km in just one night (Cheke, 1990).…”
