Summary: | As an alternative to synthetic insecticides, mineral oils and vegetable oils have been shown to be promising in controlling Bemisia tabaci biotype B. This study aimed to evaluate the effect of mineral and vegetable oils on eggs, nymphs and adults of B. tabaci biotype B, in the transmission of the bean golden mosaic virus and on dry production. The experiments were conducted at screenhouse at Embrapa Rice and Beans, Santo Antônio de Goiás, Goiás. The following oils in the concentration of 1% were used: Assist® mineral oil, Neem Max® neem oil, Veget'oil® vegetable oil, Citrole® orange oil, Castor Oil®, Sesame Oil®. The two last oils were emulsified with detergent Zupp® at 2%. Thiamethoxam at 200 g pc/ha (GD - dispersible granule) was used as a standard for comparison of chemical insecticide and distilled water as control. In all experiments, the experimental unit consisted of a polyethylene pot (34 cm diameter x 12 cm) containing two seedlings of common bean cv. Pearl. The experimental design was completely randomized with four replications / treatment. In the first experiment was evaluated the effect of oils on the mortality of eggs of B. tabaci. The second experiment was conducted to verify that the treatment of eggs with the oils would affect first instar nymphs. In the third experiment was evaluated the mortality of nymphs of the second to fourth instar after spraying of oil on the second instar nymphs. In these experiments, seedlings of bean cv. Pearl infested with eggs or nymphs of the whitefly were sprayed with 250 μL of each treatment on the abaxial surface of leaves. In the fourth experiment, four seedlings infested with adults and distributed in one m2 were sprayed with 30 ml of treatment. In the fifth experiment the effect of oils on adult mortality, the incidence of bean golden mosaic virus and crop production were evaluated by spraying only vegetable oils before the infestation of the seedlings with adults. All treatments caused mortality of eggs lesser or equal to 9.5%. Vegetable oils, when applied to eggs, caused mortality of newly-hatched nymphs lesser or equal to 22.3%. All treatments caused significant mortality of second instar nymphs, ranging from 46.5% for thiamethoxan to 81.6% for to castor oil. The treatments also affected the development of the nymphs until the fourth instar. Mortalities of nymphs greater than 80% were observed with castor, neem, sesame and orange oils. Only castor, sesame and mineral oils caused significant adult mortalities of 41.2%, 25.7% and 38.0%, respectively, one day after spraying. The orange, castor, neem and sesame oils, when sprayed prior to insect infestation of beans seedlings, caused mortality of whitefly adults ranging from 32.1% to 53.6%, one day after application. The castor and orange oils reduced the incidence of golden mosaic virus in bean. Castor oil favored greater pod yield, while the lowest pod yield was observed on sesame oil. The total number of seeds, mean number of seeds per pod and seed weight was not increased with the use of vegetable oils. The use vegetable and mineral oils have the potential to control B. tabaci biotype B. |

Esse trabalho teve como objetivo avaliar o efeito de óleos vegetais e mineral sobre ovos, ninfas e adultos da B. tabaci biótipo B e sobre a transmissão do vírus do mosaico dourado no feijoeiro e na sua produtividade. Os experimentos foram conduzidos em casa telada na Embrapa Arroz e Feijão, Santo Antônio de Goiás, Goiás. Utilizaram-se os seguintes óleos na concentração de 1%: óleo mineral Assist®, óleo de nim Max Neem®, óleo vegetal Veget’oil®, óleo de laranja Citrole®, óleo de Mamona®, óleo de Gergelim®, sendo os dois últimos emulsificados com detergente neutro Zupp® a 2%. Como padrão de comparação de inseticida químico utilizou-se o thiamethoxam a 200 g p.c./ha (granulado dispersível-GD) e como testemunha água destilada. Em todos os experimentos, a unidade experimental foi constituída por um vaso de polietileno (34 cm de diâmetro x 12 cm de altura) contendo duas plântulas do feijoeiro comum cv. Pérola. O delineamento experimental utilizado foi o inteiramente casualizado com quatro repetições/tratamento. No primeiro experimento foi avaliado o efeito dos óleos sobre a mortalidade dos ovos da B. tabaci. O segundo experimento foi instalado para verificar se o tratamento de ovos com os óleos afetaria as ninfas de primeiro ínstar da mosca-branca. No terceiro experimento foi avaliada a mortalidade de ninfas do segundo ao quarto ínstar após a pulverização dos óleos sobre ninfas do segundo ínstar. Nestes experimentos, plântulas de feijão cv. Pérola infestadas com ovos ou ninfas da mosca-branca foram pulverizadas com 250 μL de cada tratamento na face abaxial das folhas. No quarto experimento, quatro plântulas infestadas com adultos e distribuídas em um m2 foram pulverizadas com 30 ml dos tratamentos. No quinto experimento avaliou-se o efeito dos óleos na mortalidade dos adultos, na incidência do vírus do mosaico dourado do feijoeiro e na produtividade dessa cultura, pulverizando-se apenas os óleos vegetais antes da infestação dos adultos nas plântulas. Todos os tratamentos causaram mortalidade de ovos menor ou igual a 9,5%. Os óleos vegetais quando aplicados sobre os ovos, apresentaram efeito residual, causando mortalidade de ninfas recém-eclodidas menor ou igual a 22,3%. Todos os tratamentos causaram mortalidades significativas de ninfas do segundo ínstar, variando de 46,5% para o thiamethoxan até 81,6% para o óleo de mamona. Os tratamentos também afetaram o desenvolvimento das ninfas até o quarto ínstar. Foram observadas mortalidades de ninfas maiores que 80% com o óleo de mamona, nim, gergelim e laranja. Somente os óleos de mamona, gergelim e mineral causaram mortalidades significativas de adultos de 41,2%, 25,7% e 38%, respectivamente, um dia após a pulverização. Os óleos vegetais de laranja, mamona, nim e gergelim, quando pulverizados antes da infestação do inseto em plântulas de feijão, causaram mortalidade de adultos da mosca-branca variando de 32,1% a 53,6%, um dia após aplicação. Os óleos de mamona e laranja reduziram a incidência do vírus do mosaico dourado no feijoeiro. O óleo de mamona favoreceu maior produção de vagens, enquanto que o gergelim proporcionou menores valores de produção. O número total de grãos, número de grãos por vagem e massa de grãos, não foi incrementado com o uso de óleos vegetais. O uso de óleos vegetal e mineral apresenta potencial no controle da B. tabaci biótipo B.Submitted by Erika Demachki (erikademachki@gmail.com) on 2014-11-07T17:02:36Z No. of bitstreams: 2 Dissertação - Míriam de Almeida Marques - 2011.pdf: 1500273 bytes, checksum: d34aa41a75621b87445ae291524bb2e7 (MD5) license_rdf: 23148 bytes, checksum: 9da0b6dfac957114c6a7714714b86306 (MD5)Approved for entry into archive by Erika Demachki (erikademachki@gmail.com) on 2014-11-07T17:02:51Z (GMT) No. of bitstreams: 2 Dissertação - Míriam de Almeida Marques - 2011.pdf: 1500273 bytes, checksum: d34aa41a75621b87445ae291524bb2e7 (MD5) license_rdf: 23148 bytes, checksum: 9da0b6dfac957114c6a7714714b86306 (MD5)Made available in DSpace on 2014-11-07T17:02:51Z (GMT).

description |
As an alternative to synthetic insecticides, mineral oils and vegetable oils have been shown to be promising in controlling Bemisia tabaci biotype B. This study aimed to evaluate the effect of mineral and vegetable oils on eggs, nymphs and adults of B. tabaci biotype B, in the transmission of the bean golden mosaic virus and on dry production. The experiments were conducted at screenhouse at Embrapa Rice and Beans, Santo Antônio de Goiás, Goiás. The following oils in the concentration of 1% were used: Assist® mineral oil, Neem Max® neem oil, Veget'oil® vegetable oil, Citrole® orange oil, Castor Oil®, Sesame Oil®. The two last oils were emulsified with detergent Zupp® at 2%. Thiamethoxam at 200 g pc/ha (GD - dispersible granule) was used as a standard for comparison of chemical insecticide and distilled water as control. In all experiments, the experimental unit consisted of a polyethylene pot (34 cm diameter x 12 cm) containing two seedlings of common bean cv. Pearl. The experimental design was completely randomized with four replications / treatment. In the first experiment was evaluated the effect of oils on the mortality of eggs of B. tabaci. The second experiment was conducted to verify that the treatment of eggs with the oils would affect first instar nymphs. In the third experiment was evaluated the mortality of nymphs of the second to fourth instar after spraying of oil on the second instar nymphs. In these experiments, seedlings of bean cv. Pearl infested with eggs or nymphs of the whitefly were sprayed with 250 μL of each treatment on the abaxial surface of leaves. In the fourth experiment, four seedlings infested with adults and distributed in one m2 were sprayed with 30 ml of treatment. In the fifth experiment the effect of oils on adult mortality, the incidence of bean golden mosaic virus and crop production were evaluated by spraying only vegetable oils before the infestation of the seedlings with adults. All treatments caused mortality of eggs lesser or equal to 9.5%. Vegetable oils, when applied to eggs, caused mortality of newly-hatched nymphs lesser or equal to 22.3%. All treatments caused significant mortality of second instar nymphs, ranging from 46.5% for thiamethoxan to 81.6% for to castor oil. The treatments also affected the development of the nymphs until the fourth instar. Mortalities of nymphs greater than 80% were observed with castor, neem, sesame and orange oils. Only castor, sesame and mineral oils caused significant adult mortalities of 41.2%, 25.7% and 38.0%, respectively, one day after spraying. The orange, castor, neem and sesame oils, when sprayed prior to insect infestation of beans seedlings, caused mortality of whitefly adults ranging from 32.1% to 53.6%, one day after application. The castor and orange oils reduced the incidence of golden mosaic virus in bean. Castor oil favored greater pod yield, while the lowest pod yield was observed on sesame oil. The total number of seeds, mean number of seeds per pod and seed weight was not increased with the use of vegetable oils. The use vegetable and mineral oils have the potential to control B. tabaci biotype B. |
