Provedor de dados: 75
Autores: Costa,Ewerton M; Freitas,Rômulo Magno O; Silva,Paolo Augustus F; Araujo,Elton Lucio.
ABSTRACT The leafminer Liriomyza sativae (Diptera: Agromyzidae) is one of the main pests of melon crop (Cucumis melo) in the Brazilian semiarid. The aims of this study were to determine the damaged leaf area and assess the physiological responses of melon plants submitted to different levels of infestation per larvae of L. sativae. The study was carried out in a greenhouse, using plants of melon of the cultivar Iracema (yellow melon). The design utilized was completely randomized, with five treatments {control (no infestation in the leaves) and four infestation levels (1; 10; 20 and 30 larvae per leaf)} and 10 replications (melon plants). Initially we evaluated the physiological aspects: photosynthetic rate (µmol CO2/m2/s), stomatal conductance (mol...

ABSTRACT The leafminer [Liriomyza sativae (Diptera: Agromyzidae)] is one of the main pests of melon crop (Cucumis melo) in the states of Rio Grande do Norte and Ceará. Thus, adopting strategies to control this destructive insect is essential. The aim of this study was to evaluate the effect of aqueous neem seed extract, applied to soil via irrigation, on leafminer larvae, in the melon crop. An experiment was conducted in greenhouse, in completely randomized design, consisting of five treatments (four doses of aqueous neem seed extract: 1; 3; 5 and 10 g/100 mL) and the control consisting only of distilled water and 10 replicates (melon plants). The treatments were applied in a single dose, via soil irrigation. In the first stage of the evaluation, 24 hours...

Diversidade e métodos de amostragem de Hymenoptera na cultura da melancia no semiárido
Provedor de dados: 75
Autores: Costa,Ewerton M; Araujo,Elton L; Fernandes,Daniell RR; Silva,Paolo AF; Sales Junior,Rui.
Resumo: Os objetivos deste trabalho foram conhecer a fauna de Hymenoptera associada à cultura da melancia e avaliar a influência das armadilhas Pitfall, Moericke e McPhail na captura desses insetos, em ambiente semiárido no estado do Rio Grande do Norte. O levantamento foi realizado entre os meses de agosto e setembro de 2011, em área de produção comercial de melancia cv. Crimson Sweet. As coletas dos himenópteros foram realizadas, semanalmente, durante o ciclo da cultura. Para captura dos insetos, foram utilizados três tipos de armadilhas, Pitfall, Moericke e McPhail, na densidade de 20, 20 e 1 armadilha por hectare, respectivamente. As armadilhas foram instaladas sete dias após o plantio das sementes, e mantidas na área até a colheita dos frutos. Foram...
