The parasitoid assemblage associated with a lepidopteran leafminer, Coptotriche japoniella (Tischeriidae), on an evergreen tree, Eurya japonica (Theaceae), was studied in the center of Japan to explore parasitoid coexistence mechanisms. The leafminer supported 12 parasitoid species. Eight abundant or common species were classiÞed into Þve guilds according to their koinobiont/ idiobiont mode and...

Phyllocnistis citrella Stainton, the citrus-leafminer, is an important pest of citrus worldwide. Knowledge of natural parasitism levels is fundamental to the establishment of tactics of management and control of this species. This work aimed to evaluate the parasitism in two citrus orchards, one of ‘Montenegrina’ (Citrus deliciosa Ten.) and the other of ‘Murcott’ (C. sinensis (L.) Osbeck x C. r...

The leafminer Liriomyza huidobrensis Blanchard is considered a key pest for potatoes in Argentina. Population dynamics and leaf damage caused by the leafminer on seven selected potato processing varieties were assessed at Balcarce during the 2002 and 2003 growing seasons. Adult population dynamic was monitored using yellow sticky traps, while leaf damage (punctures and mines) was assessed using...

the agromyzid leafminers, liriomyza sativae blanchard and l. trifolii (burgess) (dip-tera: agromyzidae) are major pests that attack vegetables in varamin, tehran province. the parasitoids (hymenoptera: eulophidae) of these pests were investigated during 2003. the leafminer infested leaves were collected from different host plants, in particular cu-cumber (cucumis sativus l.,) and preserved unde...

Seventeen isolates ofMetarhizium anisopliae (Metschnikoff) Sorokin and three isolates of Beauveria bassiana (Balsamo) Vuillemin (Hypocreales: Clavicipitaceae) were evaluated for their pathogenicity to the adult pea leafminer, Liriomyza huidobrensis (Blanchard) (Diptera: Agromyzidae), in the laboratory. Flies were contaminated with dry conidia through a velvet material wrapped around the inner s...

1 The effects of tree diversity on herbivore–enemy interactions have received relatively little attention and even fewer studies have compared the relative influence of tree intraversus interspecific diversity on such dynamics. 2 We evaluated the effects of mahogany (Swietenia macrophylla) genotypic diversity and tree species diversity on parasitoid attack and species richness associated with P...

The development and reproduction of the citrus leafminer (CLM), Phyllocnistis citrella Stainton, were evaluated in six citrus genotypes in order to identify genotypes with resistance traits that could be applied in a program for the development of citrus varieties resistant to the citrus leafminer. Tests were conducted under controlled laboratory conditions (25 ± 1ºC, 70 ± 10% RH, and 14h photo...
