1. Silicon application as an auxiliary method to control diamondback moth in cabbage plants
RESUMO Entre as estratégias de Manejo Integrado de Pragas (MIP) estão os fatores que induzem a resistência da planta hospedeira. A adubação mineral com silício pode aumentar a resistência de plantas ao ataque de pragas. Este trabalho teve como objetivo avaliar o potencial da aplicação de silício no controle da traça-das-crucíferas (TDC), Plutella

2. Detection of carboxylesterase and esterase activity in culturable gut bacterial flora isolated from diamondback moth, Plutella xylostella (Linnaeus), from India and its possible role in indoxacarb degradation
Abstract Diamondback moth (DBM), Plutella xylostella (Linnaeus), is a notorious pest of brassica crops worldwide and is resistant to all groups of insecticides. The insect system harbors diverse groups of microbiota, which in turn helps in enzymatic degradation of xenobiotic-like insecticides. The present study aimed to determine the diversity of gut microfl

3. Development and survival of the diamondback moth, Plutella xylostella (L.) (Lepidoptera: Yponomeutidae) as a function of temperature: effect on the number of generations in tropical and subtropical regions
The diamondback moth, Plutella xylostella (L.), is the most important pest of brassicaceous crops worldwide. Since temperature is the major abiotic factor influencing insect development and thermal requirements may vary among insect populations, it is important to know the effect of temperature on development and survival of a subtropical strain of P. xylost

4. Insecticide resistance in populations of the diamondback moth, Plutella xylostella (L.) (Lepidoptera: Plutellidae), from the state of Pernambuco, Brazil
The diamondback moth Plutella xylostella (L.) has a great economic importance in Brassicaceae crops in many parts of the world. Recurrent infestations of this pest in growing areas of Pernambuco state, Brazil, have led farmers to frequently spray their crops with insecticides. However, control failures by several insecticides have been alleged by farmers. Th

5. Resistance of Diamonback moth, Plutella xylostella (L.,1758) (Lepidoptera : Plutellidae) populations from Pernambuco state to insecticides / Resistência de populações pernambucanas de traças-das-crucíferas, Plutella xylostella (L.,1758) (Lepidoptera : Plutellidae) a inseticidas
Plutella xylostella (L.) (Lepidoptera: Plutellidae), popularly known as diamondback moth, is a major pest of brassicaceae crops (e.g., kale, cauliflower, broccoli, and cabbage) throughout the world. Several insecticides have been intensively used during several cultivation cycles and, even in some areas, up to 15 to 20 applications per season have been obser

6. Performance of the fungus Beauveria bassiana (Bals.) Vuill. and castor bean oil for Plutella xylostella (L.) (Lepidoptera : Plutellidae) control / Desempenho do fungo Beaveria bassiana (Bals.) Vuill. e do óleo de mamona para controle de Plutella xylostella (L.) (Lepidoptera : Plitellidae)
A traça-das-crucíferas, Plutella xylostella (L.) (Lep.: Plutellidae) é considerada a principal praga no mundo nos sistemas produtivos de brássicas. Devido a grande utilização de agrotóxicos para o seu controle, métodos alternativos para o manejo dessa praga se fazem necessários, e o uso do fungo entomopatogênico Beauveria bassiana (Bals.) Vuill. e

7. AVALIAÇÃO DA PATOGENICIDADE E ATIVIDADE ENZIMÁTICA DE FUNGOS ENTOMOPATOGÊNICOS PARA O CONTROLE DE PLUTELLA XYLOSTELLA (LEPIDOPTERA: PLUTELLIDAE). / ENZYME CHARACTERIZATION AND PATHOGENICITY OF ENTOMOGENOUS FUNGI ON PLUTELLA XYLOSTELLA (LEPIDOPTERA: PLUTELLIDAE).
A traça-das-crucíferas tem causado grandes danos a produtores de couve e brócolis do município de Itabaiana-SE. O uso indiscriminado de agrotóxicos para o controle desta praga tem causado problemas quanto à resistência a determinados ingredientes ativos, além de comprometer a saúde dos aplicadores e o consumo dos produtos pela veiculação de resíd

8. Respostas imunológicas e mecânicas em população suscetível e resistente Plutella xylostella (L.) (Lepidoptera : Plutellidae) frente a formulações comerciais à base de Bacillus thuringiensis Berliner / Immunologicals and mecanicals responses in susceptible and resistant population of Plutella xylostella (L.) (Lepidoptera : Plutellidae) stand up to commercials formulations of Bacillus thuringiensis Berliner
The resistance of Plutella xylostella (L.) (Lepidoptera: Plutellidae) has been attributed to many mechanisms as alterations in cell membrane receptors on midgut and the immune response to Bacillus thuringiensis Berliner toxin. The research tested the possibility that after expositions to Bt formulations, insects from a susceptible population (SP) and a resis

9. Suscetibilidade de populações da traça-das-crucíferas, Plutella xylostella (L.,1758) (Lepidoptera : Plutellidae) a inseticidas / Susceptibility of populations of Diamondback Moth,Plutella xylostella (L., 1758) (Lepidoptera:Plutellidae) to insecticides
A Plutella xylostella destaca-se como o inseto de maior importância devido aos sérios danos causados à cultura das brássicas. A suscetibilidade de populações de traça-das-crucíferas aos inseticidas abamectina, deltametrina e espinosade, provenientes de três regiões brasileiras, foram comparadas através de bioensaios com imersão de folhas de couve

10. Utilização sistêmica de Bacillus thuringiensis para controle de Plutella xylostella na cultura de couve
The diamondback moth (DM) Plutella xylostella (Lepidoptera: Plutellidae) is the major pest of crucifer culture and the chemical control is the method most used to reduce its damage. An alternative to control this pest is the use of biological control agents, such as Bacillus thuringiensis (Bt). Its use is still limited when compared to chemical insecticides,

11. Parasitismo de Plutella xylostella (L.) (Lepidoptera : Plutellidae) por Oomyzus sokolowskii (Kurdjumov) (Hymenoptera : Eulophidae) / Parasitism of Plutella xylostella (L.) (Lepidoptera : Plutellidae) by Oomyzus sokolowskii (Kurdjumov) (Hymenoptera : Eulophidae)
A dispersão de parasitóides e a localização do hospedeiro podem ser influenciadas por fatores abióticos e bióticos inerentes ao parasitóide e ao seu hospedeiro. Portanto, investigou-se o efeito da idade, do fotoperíodo, e parasitismo de Oomyzus sokolowskii (Kurdjumov) (Hymenoptera: Eulophidae) submetido a diferentes densidades de Plutella xylostella

12. Avaliação a campo de uma estirpe de Bacillus thuringiensis tóxica à lepidoptera e seu possível efeito adverso sobre espécies não-alvo
The using of the Bacillus thuringiensis on the cabbage culture for the control of the diamondback moth has been an alternative commonly used by the producers to substitute the traditional chemical insecticides that cause damages to the environment and to the human health, as opposed to the biological products that are harmless to the humans so as to the non-
