Resumo: Tomato cropping is relevant worldwide and the fruits are commercialized as fresh food or for industrial processing. Pest infestation, however, reduces tomato yield with Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae) considered as key insect pest of tomatoes, in special, in Brazil due to its recent record of introduction. The pest status is directly associated to the fruit damage. Thus, studies to determine yield losses and other information to help control decision are needed. The monitoring of H. armigera infesting 11 tomato fields for processing (80 to 120 hectares each) using traps lured with sex pheromone was carried out during 2015 and 2016 crop seasons. Further, the determination of crop losses during fruiting stage was done using field cages and artificial infestation with 2nd-instar larvae during 2017 and 2018. Adult moth fluctuation monitored with pheromone traps correlated positively with densities of eggs and larvae, and percentage of damaged fruits. Concerning the evaluation of losses for caged tomatoes plants there were significant relationship of damaged fruits with yield decrease. The economic threshold (ET) level varied from 1.23 to 3.08 larvae per linear meter of tomatoes in 2017 and 2018 trials, respectively. Based on the results of the percentage of damaged fruits accumulated as a function of the adults captured in a sex pheromone traps suggest decision to control H. armigera when catching 5 to 8 adults per trap accumulated per week. Thus, depending on control costs and yield value, the decision for recommending curative control against H. armigera larvae varies between 0.99 and 2.46 larvae per linear meter of plants for processing tomatoes.

Entretanto, infestações de pragas reduzem a produtividade, com destaque para a ocorrência da Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae), em especial, no Brasil, pela sua recente introdução. O impacto econômico desta praga em tomateiro está associado a redução direta na produção devido ao broqueamento dos frutos. Portanto, estudos para a caracterização das perdas, como também, as mensurações dos níveis populacionais para orientar a adoção de controle são necessárias. O monitoramento da H. armigera foi realizado com armadilhas de feromônio sexual em 11 áreas comerciais de tomate para processamento industrial (80 a 120 hectares cada) durante as safras de 2015 e 2016. Também, o nível de dano econômico (NDE) foi determinado mediante o confinamento de plantas de tomate na fase reprodutiva, em gaiolas em campo, e infestadas com larvas de segundo instar, em 2017 e 2018. A captura de adultos em armadilha de feromônio foi positivamente correlacionada com a infestação de ovos, larvas e porcentagem de frutos broqueados na planta. Referente à avaliação de perdas em tomateiro confinado em gaiolas, diferenças significativas foram encontradas nas relações entre a densidade larval, porcentagem de frutos broqueados, produção e perda de rendimento. O NDE variou entre 1,23 a 3,08 larvas por metro linear de plantas nas duas safras. Com base nos resultados da porcentagem de frutos broqueados acumulados em função da captura acumulada de adultos em armadilha iscada com feromônio sexual, sugere-se a tomada de decisão de controle de H. armigera quando for capturado de 5 a 8 adultos por armadilha acumulado na semana. Ainda, a depender do custo de controle e valor da produção, o nível de controle recomendado varia entre 0,99 a 2,46 larvas de H. armigera por metro linear de plantas de tomateiro para processamento industrial.Submitted by Mario BC (mario@bc.ufrpe.br) on 2019-11-25T13:18:36Z No. of bitstreams: 1 Nayara Cristina de Magalhaes Sousa.pdf: 1075737 bytes, checksum: 208fc45b0325103be306570c6ca283e9 (MD5)Made available in DSpace on 2019-11-25T13:18:36Z (GMT).
