Application of ionizing radiation in the "licuri" (Syagrus coronata (Mart.)) as phytosanitary treatment of the Pachymerus nucleorum beetle (Fabricius, 1792). Brazilian Journal of Radiation Sciences, v. 9, n. 1A, p. 1-9, 2021. DOI: 10.15392/bjrs.v9i1A.1576

    Abstract: Pachymerus nucleorum (Fabricius, 1792), is a pest of economic importance it causes direct damages to the “licuri” almonds. The objective of this study was to determine the lethal doses of gamma radiation for stages egg, larvae, and pupae of this insect as a phytosanitary treatment in “licuri”. The samples were irradiated in a Cobalt 60 irradiator, Gammacell-220 type, installed at the Institute of Energy and Nuclear Research - IPEN / CNEN at a dose rate of 748 Gy / h. Each treatment consisted of 3 replicates, so 180 licuri were irradiated in the doses of 50, 75, 100, and 125 Gy. After irradiation, the samples were stored at a temperature of 25 ± 5°C and relative humidity of 70 ± 5%. The evaluation of the fruits was performed by the emergence of insects. It is concluded that the dose of 125 Gy was sufficient to inhibit the development of insect life stages. Therefore, this dose of radiation can be used for control of the immature stages of the P. nucleorum.

Application of ionizing radiation in the coconuts of “Licuri” Syagrus Coronata (mart.) in the control of the Pachymerus Nucleorum beetle (Fabricius, 1792). In: INTERNATIONAL NUCLEAR ATLANTIC CONFERENCE, October 21-25, 2019, Santos, SP. Proceedings... Rio de Janeiro: Associação Brasileira de Energia Nuclear, 2019. p. 2141-2149.

    Abstract: The “licuri” fruit palm (Syagrus coronata) is harvested extractively from palm trees that grow in native forests, pastures, and in association with other cultures being part of the regional economy in the hinterland of Bahia. Among the problems related to the “licuri” palm is the insect specie Pachymerus nucleorum (Fabricius, 1792), which stands out as a pest of economic importance because it causes direct damages to the “licuri's” almonds. Due to this the objective of the work was to determine the lethal doses of gamma radiation for the phases of egg, larvae and pupae of Pachymerus nucleorum aiming at its control in almonds of coconuts of licuri. A Cobalt 60 irradiator, Gammacell-220 type, installed at the Institute of Energy and Nuclear Research - IPEN / CNEN, located in São Paulo / Brazil, at a dose rate of 748 Gy / h, was used to carry out the research with the Pachymerus nucleorum biological cycle. Each treatment for all stages of egg, larvae and pupae inside of coconuts consisted of 3 replicates with 12 coconuts each, in a total of 216 coconuts per test that were irradiated in the following doses: 0 (control), 50, 75, 100 and 125 Gy. After irradiation, the samples were stored at a temperature of 25 ± 5 ° C and relative humidity of 70 ± 5%, where the development of egg, larvae and pupae stages until adult transformation in irradiated almonds. From the results obtained it is concluded that the dose of 125 Gy was sufficient to interrupt the development of the phases of the insect. Therefore, this dose of radiation can be used for quarantine treatment of the immature stages of Pachymerus nucleorum in the coconuts of “licuri” Syagrus coronata palm.

DOI: 10.15392/bjrs.v9i1A.1444

    Abstract: The objective of experiment was determinate the radiation dose for disinfestation to mango Mangifera indica cv. Haden, infested by Anastrepha fraterculus larvae. For realization of the experiment, were collected fruits in the field, which were taking to Entomology laboratory where there was an infestation by the flies in cages during 72 hours period. Waited for the development of the larvae 5 and 8 days to infestation, after the mangos were irradiated in a Cobalt-60 source with doses of: 0(control), 50, 100, 200, 300, 400, 500, 600, 700, 800, 900, 1000, 1.100, 1.200 and 1.300 Gy. After the irradiation, the fruits were placed in climate chamber with 25 ±5°C of temperature and 70±5% of relative humidity. Waited the larvae exit to out of the fruit until the transformation in pupae and adult stage. By the results obtained we can concluded that the lethal dose to larvae in mangoes infested with 5 and 8 days were 600 Gy and 1.000 Gy (0.6 and 1 kGy) respectively. The dose of 50 Gy prevented the total adult emergence for both treatments.

    HADDAD, GIANNI Q.; MACHI, ANDRE R. ; ARTHUR, VALTER . Gamma radiation for all phases of life cycle of cotton bollworm Helicoverpa armigera aiming at its control. In: INTERNATIONAL NUCLEAR ATLANTIC CONFERENCE, October 22-27, 2017, Belo Horizonte, MG. Proceedings... Rio de Janeiro, RJ: Associação Brasileira de Energia Nuclear, 2017.

    Abstract: Since the 1950s, scientists have used ionizing radiation to sterilize insects, which are released in nature to mate, but without any progeny. Known as the sterile insect technique (SIT), this insect control method traditionally uses ionizing radiations to sterilize insects, being a technique that does not generate residue, and can act in synergy with the other techniques within integrated pest management. For several years, Brazil has been fighting against the increase of pests, introducing new tactics and techniques within IPM programs, to overcome the resistance of chemical products, such as: reducing residues of pesticides. For some important crops of our country, we have a wide spectrum of pests occurring from beginning to end of the harvest, one of them is the cotton crop and among the key pests of this crop, we have some extremely important caterpillars among them Helicoverpa armigera. Due to this the objective this study was establishes doses of gamma radiation to sterilizing of the phases of : eggs, larvae, pupae and adults of H. armigera aiming their control. The experiment was carried out with application of gamma radiation from a Cobalt-60 source. The treatments consisted of doses of gamma radiation varying of according with the insect phase, being this variation of: 0 (control) to 400 Gy. The experiments with pupae and adult phases showed satisfactory results in the sterilization of H. armigera for use in autocide control programs. The sterilize dose to adult and pupae phase were 400 Gy and 100 Gy respectively, being the best doses for the application of the sterile insect technique to this pest in cotton.

Larval application of sodium channel homologous dsRNA restores pyrethroid insecticide susceptibility in a resistant adult mosquito population. Parasites & Vectors, v. 9, n. 397, p. 1-14, 2016. DOI: 10.1186/s13071-016-1634-y

    Abstract: Background: Mosquitoes host and pass on to humans a variety of disease-causing pathogens such as infectious viruses and other parasitic microorganisms. The emergence and spread of insecticide resistance is threatening the effectiveness of current control measures for common mosquito vector borne diseases, such as malaria, dengue and Zika. Therefore, the emerging resistance to the widely used pyrethroid insecticides is an alarming problem for public health. Herein we demonstrated the use of RNA interference (RNAi) to increase susceptibility of adult mosquitoes to a widely used pyrethroid insecticide. Methods: Experiments were performed on a field-collected pyrethroid resistant strain of Ae. aegypti (Rio de Janeiro; RJ). Larvae from the resistant Ae. aegypti population were soaked with double-stranded RNAs (dsRNAs) that correspond either to voltage-gate sodium channel (VGSC), P-glycoprotein, or P450 detoxification genes and reared to adulthood. Adult mortality rates in the presence of various Deltamethrin pyrethroid concentrations were used to assess mosquito insecticide susceptibility. Results: We characterized the RJ Ae. aegypti strain with regard to its level of resistance to a pyrethroid insecticide and found that it was approximately 6 times more resistant to Deltamethrin compared to the laboratory Rockefeller strain. The RJ strain displayed a higher frequency of Val1016Ile and Phe1534Cys substitutions of the VGSC gene. The resistant strain also displayed a higher basal expression level of VGSC compared to the Rockefeller strain. When dsRNA-treated mosquitoes were subjected to a standard pyrethroid contact bioassay, only dsRNA targeting VGSC increased the adult mortality of the pyrethroid resistant strain. The dsRNA treatment proved effective in increasing adult mosquito susceptibility over a range of pyrethroid concentrations and these results were associated with dsRNA-specific small interfering RNAs in treated adults, and the corresponding specific down regulation of VGSC gene expression level. Finally, we demonstrated that the efficiency of our approach was further improved by ‘tiling’ along the VGSC gene in order to identify the most potent dsRNA sequences. Conclusions: These results demonstrate that dsRNA applied to mosquito larvae retains its biological activity into adulthood. Thus, the RNAi system reported here could be a useful approach to control the widespread insecticide resistance in mosquitoes and other insect vectors of human diseases.

    ARTHUR, VALTER ; ARTHUR, PAULA B. ; MACHI, ANDRÉ R. . Pupation, adult emergence, and F1 egg hatch after irradiation of Spodoptera frugiperda (Lepidoptera: Noctuidae) last instars. Florida Entomologist, v. 99, Special issue 2, p. 59-61, 2016.

    Abstract: The fall armyworm, Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae), is a quarantine pest that may be found as eggs or larvae on a number of fresh vegetable and fruit commodities. The objective of the research was to evaluate the effects of gamma radiation as a phytosanitary treatment applied to the 5th (last) instar larvae. Larvae were reared on an artificial diet. Each treatment of twenty 15–20 d-old larvae had 5 repetitions. The larvae were irradiated with doses of gamma radiation of 0 (non-irradiated control), 50, 100, 200 and 300 Gy in a Cobalt-60 source (Gammacell-220) at a dose rate of 508 Gy/h. Pupation, adult emergence and hatching of F1 eggs were monitored. When the last instars were irradiated with100 Gy the rates of pupation, adult emergence and F1 egg hatch were 85, 39 and 50 percent, respectively, and the corresponding values in the non-irradiated control were 95, 85 and 90 percent, respectively. However, when the last instars were irradiated with 200 Gy, the pupation rate was reduced to 30 percent and adult emergence was reduced to 10 percent, and all of the adults that emerged were deformed, unable to fly, and died after about 2 h. Therefore, irradiation with 200 Gy is recommended as the appropriate dose for phytosanitary irradiation of S. frugiperda eggs and larvae. In addition this study supports the previously proposed generic dose of 250 Gy for eggs and larvae of lepidopteran pest species generally.

Quarantine treatment by gamma radiation for different development stages of Callosobruchus maculatus in bean Vigna sinensis. In: INTERNATIONAL NUCLEAR ATLANTIC CONFERENCE, October 22-27, 2017, Belo Horizonte, MG. Proceedings... Rio de Janeiro, RJ: Associação Brasileira de Energia Nuclear, 2017.

    Abstract: The loss of stored grain caused by insects generates a problem of economic order of importance, due to concern about the increased supply of food for the world population is expanding. Associated with this fact, there is the problem of nutritional deficiency due to lack of protein, especially for the less privileged populations. The use of ionizing radiation in grains and products stored without a doubt can solve the problem of the losses in these products, since it does not induce resistance to insects and leaves no toxic residue in the products, and is considered an effective and safe method. The aim of the experiment was to determine the effect of ionizing radiation from cobalt-60 as a quarantine treatment for the different stages of development of Callosobruchus maculatus (Fabr., 1972) (Coleóptera, Chysomilidae) in bean Vigna sinensis. The experiment was conducted in the laboratory of Radiobiology and Environment CENA / USP., Piracicaba, SP, Brazil. Bean samples infested with eggs, larvae, pre-pupae and pupae C. maculatus, the experiment consisted of 4 replicates for each stage of the insect's life cycle, and each repetition consisted of 20 individuals (eggs, larvae, pre-pupae and pupae), a total of 200 subjects per treatment which were irradiated with doses of 0 (control), 25, 50, 75 and 100 Gy, a source of cobalt-60, Gammabeam-650 type, in a rate dose of 1.3 kGy / h. The experiment was conducted in a room with a relative of 25 ± 2 ° C temperature and humidity of 70 ± 5%. After 35 days of irradiation process were carried out evaluations of the number of insects emerged in each repetition within the treatments. From the results obtained it was concluded that the dose lethal to eggs and larvae was 25 Gy, while for pre-pupae was 50 Gy, to pupae 100 Gy was not sufficient to control the adult emergence.

O Repositório Digital do IPEN é um equipamento institucional de acesso aberto, criado com o objetivo de reunir, preservar, disponibilizar e conferir maior visibilidade à Produção Científica publicada pelo Instituto, desde sua criação em 1956.

Operando, inicialmente como uma base de dados referencial o Repositório foi disponibilizado na atual plataforma, em junho de 2015. No Repositório está disponível o acesso ao conteúdo digital de artigos de periódicos, eventos, nacionais e internacionais, livros, capítulos, dissertações, teses e relatórios técnicos.

O gerenciamento do Repositório está a cargo da Biblioteca do IPEN. Constam neste RI, até o presente momento 20.950 itens que tanto podem ser artigos de periódicos ou de eventos nacionais e internacionais, dissertações e teses, livros, capítulo de livros e relatórios técnicos. Para participar do RI-IPEN é necessário que pelo menos um dos autores tenha vínculo acadêmico ou funcional com o Instituto. Nesta primeira etapa de funcionamento do RI, a coleta das publicações é realizada periodicamente pela equipe da Biblioteca do IPEN, extraindo os dados das bases internacionais tais como a Web of Science, Scopus, INIS, SciElo além de verificar o Currículo Lattes. O RI-IPEN apresenta também um aspecto inovador no seu funcionamento. Por meio de metadados específicos ele está vinculado ao sistema de gerenciamento das atividades do Plano Diretor anual do IPEN (SIGEPI). Com o objetivo de fornecer dados numéricos para a elaboração dos indicadores da Produção Cientifica Institucional, disponibiliza uma tabela estatística registrando em tempo real a inserção de novos itens. Foi criado um metadado que contém um número único para cada integrante da comunidade científica do IPEN. Esse metadado se transformou em um filtro que ao ser acionado apresenta todos os trabalhos de um determinado autor independente das variáveis na forma de citação do seu nome.
