1. Effect of the chitin synthesis inhibitor triflumuron on the development, viability and reproduction of Aedes aegypti
The control of Aedes aegypti is impaired due to the development of resistance to chemical insecticides. Insect Growth Regulators (IGR) exhibit distinct mechanisms of action and are considered potential vector control alternatives. Studies regarding the effects of sublethal IGR doses on the viability of resulting adults will contribute to eval-uating their im

3. Padronização da expressão heterologa e de modelo de ensaio de atividade para a proteina quinase humana S6K / Standardization of the heterologous expression and of a model assay of activity for the human protein kinase S6K
The 70kDa ribosomal S6 protein kinase 1 (S6K1) is a phosphoprotein involved in the regulation of genes related to translational control in mammals. S6K1 shows distinct nuclear (a1) and cytoplasmic (a2) forms. Phosphorylation of the S6K1 best characterized target, the protein of the small ribosomal subunit (RPS6), has been generally associated to the selectiv

4. Efeito de alguns inseticidas sobre a mariposa Plutella xylostella (L., 1758) (Lepidoptera, Plutellidae) por meio de iscas esterilizantes. / Inseticide effects on the diamondback moth Plutella xylostella (L., 1758) (Lepidoptera, Plutellidae) by using sterilizing baits.
Plutella xylostella (L., 1758) (Lepidoptera, Plutellidae), commonly known as diamondback moth, is an important pest of Brassicaceae in Brazil and several other countries. Its control is usually done with frequent applications of conventional insecticides. However, this approach is sometimes ineffective, besides some drawbacks such as environmental contaminat

5. Susceptibilidade de Aedes aegypti (L) aos reguladores de crescimento de insetos diflubenzuron e methoprene em Uberlândia, Estado de Minas Gerais
Aedes aegypti (L) (Diptera: Culicidae) foi criado em várias concentrações de diflubenzuron e methoprene sob condições de laboratório em Uberlândia, Minas Gerais, sudeste do Brasil. Foram estudados aspectos tais como, CL50 e CL95, suscetibilidade de estágios imaturos de diferentes idades a estes insect growth regulators e seu efeito residual. As CL50

6. Susceptibilidade de Digitonthophagus gazella (Fabricius : 1787) (Coleoptera: Scarabaeidae) aos reguladores de crescimento de insetos (IGRs) Diflubenzuron e Methoprene em UberlÃndia, MG
The Insect Growth Regulators are considered more selective than the conventional insecticides, are not toxic to mammals if used in the recomended dose and are easily degradable in environment. Diflubenzuron and Methoprene are IGRs from the chitin sinthesis inibithors and juvenile hormones analogs classes, respectively. These IGRs show comprovated eficience a

7. Chemosterilization of the sugarcane borer Diatraea saccharalis (Fabricius, 1794) (Lepidoptera: Crambidae) with sugar solution bait and insecticides of insect growth regulators group / Esterilização química da broca da cana-de-açúcar Diatraea saccharalis (Fabricius, 1794) (Lepidoptera: Crambidae) através de isca com melaço e inseticidas do grupo dos reguladores de crescimento de insetos
A broca da cana-de-açúcar Diatraea saccharalis (Fabricius, 1794) (Lepidoptera: Crambidae) é uma das pragas mais prejudiciais aos canaviais brasileiros. Atualmente, o controle biológico aplicado é o método mais utilizado para o controle das lagartas. Entretanto, em certos talhões, o parasitóide Cotesia flavipes (Cameron) (Hymenoptera: Braconidae) não

8. Control of the german cockroach Blattella germanica with Metarhizium anisopliae and insect growth regulators. / Controle de Blattella germanica (L.) com Metarhizium anisopliae e inseticidas reguladores de crescimento.
It was evaluated the effect of Metarhizium anisopliae and the insect growth regulators triflumuron and pyriproxifen for adults and nymphs of the German cockroach Blattella germanica, and the efficacy of its association in the control of this urban pest. High doses of the pathogen caused high mortality of adults and nymphs. There was no mortality of B. german

10. Insect juvenile hormone resistance gene homology with the bHLH-PAS family of transcriptional regulators
Juvenile hormone analog (JHA) insecticides are relatively nontoxic to vertebrates and offer effective control of certain insect pests. Recent reports of resistance in whiteflies and mosquitoes demonstrate the need to identify and understand genes for resistance to this class of insect growth regulators. Mutants of the Methoprene-tolerant (Met) gene in Drosop

11. Bruchins: Insect-derived plant regulators that stimulate neoplasm formation
Pea weevil (Bruchus pisorum L.) oviposition on pods of specific genetic lines of pea (Pisum sativum L.) stimulates cell division at the sites of egg attachment. As a result, tumor-like growths of undifferentiated cells (neoplasms) develop beneath the egg. These neoplasms impede larval entry into the pod. This unique form of induced resistance is conditioned

12. Differential lipid biosynthesis underlies a tradeoff between reproduction and flight capability in a wing-polymorphic cricket
The biochemical basis of life-history tradeoffs is a poorly studied aspect of life-history evolution. We used radiotracer and endocrine approaches to investigate the extent to which morphs of a wing-polymorphic insect differ in the biosynthesis of lipid classes important for dispersal capability vs. reproduction (ovarian growth). The flight-capable genotype
