Among nematodes parasitizing bananas throughout the world, Radopholus similis and Helicotylenchus multicinctus are the most widespread and damaging species. Besides these two nematodes, Hoplolaimus pararobustus is encountered frequently in Ivory Coast and has been increasing in banana growing areas for the past 25 years (6,10). In vitro culture systems could facilitate screening for resistance ...

A diverse Diptera assemblage, dominated by the family Chloropidae, is associated with common reed (Phragmites australis (Cav.) Trin. ex Steudel, Poaceae) in the Palearctic region (Tewksbury et al. 2002). Although P. australis has long been present in North America, many of its associated Chloropidae have remained restricted to the Palearctic. The best-known chloropid associates of Phragmites ar...

The distribution of banded rail habitat use in a saltmarsh was measured by recording the rate at which their footprints accumulated. The relationships between habitat use, time of day, state of the tide, and 15 environmental parameters, were investigated using multivariate analysis. Banded rails were most active in the morning and evening and immediately after a tide. They did not venture far f...

Heliothrips similis sp.n. is described as a close relative of the greenhouse thrips, Heliothrips haemorrhoidalis. This is the third species recognized here in the Neotropical genus Heliothrips. A pest species described from South Africa as Heliothrips sylvanus is transferred to a new genus, Neoheliothrips gen.n., as Neoheliothrips sylvanus (Faure) comb.n.

The Oriental species of Microplitis Foerster are reviewed. 21 species are recognized from the Oriental region, of which two are described as new, Microplitis narendrani sp. nov. and M. pennatulae sp. nov., and Microplitis carinicollis (Cameron), M. demolitor Wilkinson, M. maculipennis (Szépligeti) and M. similis Lyle are redescribed. Four species, Microplitis areyongensis Austin & Dangerfield, ...

A lesion nematode, Pratylenchus gutierrezi n. sp., collected from the roots of coffee in the Central Plateau of Costa Rica, is described and illustrated. Its relationships to Pratylenchus flakkensis, P. similis, and P. gibbicaudatus, the only other species of the genus having two head annules, males, or spermatheca with sperm, and an annulated tail terminus, is discussed. Other distinctive char...
