Resumo: | Use of synthetic insecticides remains the main tactic used to control agricultural pests. Small growers, such as cabbage producers of agricultural areas of Pernambuco, use synthetic insecticides as the main way to solve their problems with insect pests. However improper use results in a high number of insecticide sprays, resulting in undesirable side effects such as, the natural biological control depression, incease of the production cost, developing of insect resistance to pesticides, among others. Diamondback moth (L.) (Lepidoptera: Plutellidae) is the main pest of the family Brassicaceae, and the insect which has the highest reported cases of resistance to synthetic insecticides, so that spraying of such products has shown inefficiency. The need to develop new chemicals for pest control has increased the development of researchs with botanical insecticides. Essential oils of the species Mentha arvensis L., Mentha piperita L. and Mentha spicata (L.) has shown insecticidal activity against a wide variety of arthropods, causing repellent, ovicidal, larvicidal, and feeding deterrent effects and still affecting biological parameters to such organisms. The oils of Mentha species showed an interesting insecticidal action against 3rd-instar larvae of DBM producing DL50 lower the que Azamax, a synthetic insecticide of plant origin. However the insecticides Premio® 200 SC and Decis® 25 EC, had a lower DL50 all oils. The spraying of oils over the eggs inhibited the emergence of P. xylostella. The exhibition of DBM larvae to sublethal doses of the Mentha species oils caused effects on biological parameters, affecting the percentage of pupation, pupal weight, viability of eggs, larval survival and viability of offspring. |

Pequenos agricultores, como os produtores de couve das áreas de Pernambuco, usam os inseticidas sintéticos como o principal meio para solucionar seus problemas com insetos pragas. Entretanto, o uso inadequado resulta em um elevado número de pulverizações ocasionando efeitos indesejáveis como depressão do controle biológico natural, aumento do custo de produção, desenvolvimento de resistência de insetos aos inseticidas, entre outros. Plutella xylostella (L.) (Lepidoptera: Plutellidae) é a principal praga da família Brassicaceae, e é o inseto que apresenta o maior registro de casos de resistência aos inseticidas sintéticos, de tal modo que a pulverização desses produtos tem demonstrado ineficiência. A necessidade de desenvolver novos compostos químicos para o controle de pragas tem impulsionando o desenvolvimento de pesquisas com inseticidas botânicos. Os óleos essenciais das espécies Mentha arvensis L., Mentha piperita L. e Mentha spicata (L.) tem apresentado ação inseticida contra uma vasta diversidade de artrópodes, desempenhando efeito repelente, ovicida, larvicida, deterrente alimentar e ainda afetando parâmetros biológicos desses organismos. Os óleos das espécies de Mentha mostraram uma interessante ação inseticida contra lagartas de 3º instar de P. xylostella apresentando DL50 menor que o Azamax, um inseticida sintético de origem vegetal. Entretanto os inseticidas comerciais, Premio® 200 CS e Decis® 25 CE, tiverem uma DL50 menor que todos os óleos testados. A pulverização dos óleos sobre os ovos inibiu a eclosão de P. xylostella. A exposição das lagartas de P. xylostella às doses subletais dos óleos das espécies Mentha ocasionou efeito sobre seus parâmetros biológicos, afetando o percentual de pupação, peso de pupa, viabilidade de ovos, sobrevivência e viabilidade larval da prole.Submitted by Mario BC (mario@bc.ufrpe.br) on 2018-12-05T13:24:17Z No. of bitstreams: 1 Antonio de Almeida Paz Neto.pdf: 941208 bytes, checksum: e4780c302bbbd82d00ef7925929887de (MD5)Made available in DSpace on 2018-12-05T13:24:17Z (GMT).

Use of synthetic insecticides remains the main tactic used to control agricultural pests. Small growers, such as cabbage producers of agricultural areas of Pernambuco, use synthetic insecticides as the main way to solve their problems with insect pests. However improper use results in a high number of insecticide sprays, resulting in undesirable side effects such as, the natural biological control depression, incease of the production cost, developing of insect resistance to pesticides, among others. Diamondback moth (L.) (Lepidoptera: Plutellidae) is the main pest of the family Brassicaceae, and the insect which has the highest reported cases of resistance to synthetic insecticides, so that spraying of such products has shown inefficiency. The need to develop new chemicals for pest control has increased the development of researchs with botanical insecticides. Essential oils of the species Mentha arvensis L., Mentha piperita L. and Mentha spicata (L.) has shown insecticidal activity against a wide variety of arthropods, causing repellent, ovicidal, larvicidal, and feeding deterrent effects and still affecting biological parameters to such organisms.
