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...

Provedor de dados: 75
Autores: Costa,Ewerton M; Silva,Francisco EL; Araujo,Elton L.
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...

Antispila sp. minatore fogliare segnalato in Italia su vite = Antispila sp. a new leafminer of grapes in Italy
Provedor de dados: 16
Autores: Baldessari, M.; Angeli, G.; Girolami, V.; Mazzon, L.; Nieukerken, E.J. van; Duso, C.
Two leaf-miner species occur in European vineyards, i.e. Holocacista rivillei (Stainton) (Lepidoptera Heliozelidae) and Phyllocnistis vitegenella Clemens (Lepidoptera Phyllocnistidae).  In the summer of 2007, leaf mines similar to those caused by H. rivillei were observed in a vineyard located in north-eastern Italy. However, the first portion of mines (linear tortuous) was lacking and thus the occurrence of a different species was suspected. Larvae were reared in controlled conditions to obtain adults and the latter differed from those of H. rivillei because of their size and wing patterns. Adults belonged to the genus Antispila Hübner, but not to the species of this genus currently known for Italy and Europe. Antispila sp. was detected for the first time...

Identification of the female-produced sex pheromone of the leafminer Holocacista capensis infesting grapevine in South Africa
Provedor de dados: 16
Autores: Wang, H.-L.; Geertsema, H.; Nieukerken, E.J. van; Löfstedt, C.
We report the first identification of a sex pheromone in a heliozelid moth, Holocacista capensis van Nieukerken &amp; Geertsema. This leafminer recently infested grapevine in South Africa. Compared to solvent extraction of pheromone glands, solid phase microextraction (SPME) proved to be highly effective for collection of the pheromone from calling females. The volatiles collected by SPME were analyzed by gas chromatography with electroantennographic detection (GC/EAD). Three compounds eliciting electrophysiological activity from the male antenna were identified as (Z)-5-tetradecenal, (Z)-7-tetradecenal, and (Z)-9-hexadecenal by coupled gas chromatography–mass spectrometry (GC/MS). GC/MS analysis of dimethyldisulphide (DMDS) derivatives of fatty acyl...

Autores: Vargas,HA.
The presence of Stigmella epicosma (Meyrick) is reported for the first time from two coastal valleys from northern Chile: Azapa and Chaca. Adults examined were reared from leafminer larvae on Trixis cacalioides (Asteraceae), the first host plant known for S. epicosma.

Record of Diglyphus walker (Hymenoptera: Eulophidae) species in Brazil
Provedor de dados: 82
Autores: Carvalho,AR; Bueno,VHP; Silva,DB; Costa,VA.
Leafminers (Diptera: Agromyzidae) are pests of various crops, mainly in greenhouses, and have Diglyphus spp. as important leafminer larval parasitoids. Until recently, only Diglyphus insularis (Gahan) had been reported in Brazil. In here we report the first records of Diglyphus begini (Ashmead), D. intermedius (Girault) and D. isaea (Walker) in Brazil. These parasitoids were found parasitizing leafminer larvae on cultivated and spontaneous plants in some areas of Minas Gerais state, Brazil.

Phyllocnistis citrella Stainton (Lepidoptera: Gracillariidae) and its relationship with the citrus canker bacterium Xanthomonas axonopodis pv citri in Brazil
Provedor de dados: 82
Autores: Chagas,Marcone C.M.; Parra,José R.P.; Namekata,Takao; Hartung,John S.; Yamamoto,Pedro T.
The relationship of the citrus canker bacterium Xanthomonas axonopodis pv citri with the citrus leafminer (CLM), Phyllocnistis citrella Stainton was investigated. The experiment was conducted under laboratory conditions at 28±2ºC, 70±10% RH and 14h photophase and in a greenhouse. Sweet orange (Citrus sinensis L. Osbeck) "Caipira"cv was used to rear CLM. Plants inoculated with 2nd and 3rd instar larvae or pupae showed high percentages (94.3, 98.3 and 100%, respectively) of bacterium-infected leaves. The damage caused by this insect was responsible for the increase in citrus canker infestation. The leaf infection rate by X. axonopodis pv citri on pre-injured leaves was similar to that observed on mechanically damaged leaves inoculated with the bacterium,...

Parasitoids of Phyllocnistis citrella in Jaguariúna, state of São Paulo, Brazil, before and after the introduction of Ageniaspis citricola
Provedor de dados: 63
Autores: Sá,Luiz Alexandre Nogueira de; Costa,Valmir Antonio; Oliveira,Wagner Portes de; Almeida,Gilberto Ribeiro de.
The citrus leafminer, Phyllocnistis citrella (Gracillariidae), is among the main pests of citrus in Brazil. The objective of this work was to conduct a survey of parasitoids attacking CLM in Jaguariúna, State of São Paulo, Brazil, before and after the introduction of Ageniaspis citricola (Encyrtidae). Collections of new leaves were made weekly at citrus groves from July-1997 to April-1999. During the survey period, A. citricola was introduced in the area. Before this introduction, Galeopsomyia fausta (Eulophidae) was the predominant species (about 91.83% of the species composition), but A. citricola became predominant after its establishment (60.10% against 38.30% G. fausta). Other parasitoids found were Cirrospilus sp. C (Eulophidae), Horismenus sp....

Method for maintenance of coffee leaves in vitro for mass rearing of Leucoptera coffeellum (Guérin-Méneville) (Lepidoptera: Lyonetiidae)
Provedor de dados: 44
Autores: Reis Jr.,Ronaldo; Lima,; Vilela,Evaldo F.; Barros,Raimundo S.
To accomplish systematic studies with coffee leafminer, it is necessary to establish a mass rearing system under artificial conditions. It is possible to rear this species, from egg to adult, under laboratory conditions, without using coffee seedlings but detached leaves maintained in vitro. Synthetic cytokinins are routinely used for maintenance of plant cell and plant tissues in vitro. Two plant growth regulators, benzyladenin and kinetin, in concentrations 10-6 and 10-7 M were used to mantain the leaves. Green leaves collected in the field were maintained in the solution to be tested. Distilled water served as control. The experiment lasted 30 days, a period longer than the necessary for the complete development of the insect. Both artificial...
