Miculenchus salvus Andrassy, 1959 is reported from Loch Ness, Scotland. It has been originally identified as Zanenchus salmae Siddiqi, 1979; the transfer of this species to Miculenchus Andrassy, 1959 and its synonymy with M. salvus, Andrassy, 1959 is proposed. The zigzag structure of the body cuticle and the male penial tube is illustrated by Nomarski interference-contrast microscopy.

Soil samples taken in eastern Kenya contained Xiphinema brevicolle Lordello & Da Costa, 1961; X. oxycaudatum Lamberti & Bleve-Zacheo, 1979; and X. simile Lamberti et al., 1983. These species are reported for the first time from Kenya, X. oxycaudatum is reported for the first time outside the country from where it was originally described and X. simile is reported for the first time outside Europe. The Kenyan specimens have been compared with topotypes (X. brevicolle) or original type material (X. oxycaudatum and X. simile).

Au cours d'une enquete effectuee a la Martinique en 1992, 498 echantillons de sol et de racines ont ete preleves sur huit plantes ornementales appartenant a trois familles botaniques differentes, les Araceae, les Gingiberaceae et les Strelitziaceae ainsi que 50 echantillons de racines d'Anthurium sp. cultives sur substrat artificiel. Cette enquete a permis l'identification de 27 especes de nematodes phytoparasites differents appartenant a 18 genres, dont une espece nouvelle, Criconemoides ornativulvatus et deux autres repertoriees pour la premiere fois a la Martinique, Helicotylenchus pseudorobustus et Monotrichodorus sacchari.

A cote des especes rares appartenant aux Criconematidae, Longidoridae, Trichodoridae et Tylenchulidae, originaires du milieu naturel, on observe des peuplements caracterises par la dominance d'une ou de plusieurs especes comme Meloidogyne spp. pour les Alpinia; Radopholus similis pour les Anthurium, meme cultives sur substrat; Aorolaimus luci sur Etlingera elatior et Pratylenchus coffeae sur Alocasia macrorrhiza.

Information on the distribution and occurrence of Trichodorus and Paratrichodorus species and their associations with tobraviruses in Europe and the former Soviet Union (FSU) is reviewed. A total of 17 Trichodorus and 13 Paratrichodorus species have been reported and of those, 14 have been reported to transmit virus. Paratrichodorus pachydermus and Trichodorus primitivus are the species most often associated with virus transmission.

The distribution of virus-vector nematodes has been studied in detail in Europe. The resulting maps were used to determine the extremes of the European geographical range of Longidorus elongatus and Xiphinema diversicaudatum. The CLIMEX computer programme was used to fit a model to the known European distributions of these nematode species and project these to ascertain their potential world distribution. Implications for the application of the CLIMEX model to refine quarantine regulations for other plant-parasitic nematodes are discussed.

Two new Xiphinema species are described from Kenya. X. masaiorum n. sp. is close to X. limbeense and X. malawiense, but can be distinguished from both these species by differences in tail shape, as well as in various measurements and ratios. It is also compared with X. abrantinum, from which it differs in size, lip region shape and absence of males. X. kikuyense n. sp. is compared with X. malagasi, X. limbeense, X. malawiense and X. rarum. From X. limbeense and X. malawiense it differs in the possession of uterine spines, and from the former three species in the presence of males. It differs from X. rarum in the length of the hyaline tail tip and especially in shape and size of the male tail.

Entomopathogenic nematode (Rhabditia: Steinernematidae and Heterorhabditidae) infective juveniles can survive adverse environmental conditions by remaining in the host cadaver for up to 50 days. Survival varies among the species and is dependent upon the environmental conditions to which the cadaver is exposed. Galleria mellonella larvae were infected at 25°C with one of four nematode species and then exposed to relative humidities (r.h.) of 75, 85, 96 or 100%. Significantly fewer Heterorhabditis bacteriophora and Steinernema feltiae emerged at low relative humidities, but relative humidity did not affect emergence of S. glaseri or S. carpocapsae. In a second experiment, G. mellonella were infected with nematodes at 25°C and either kept at 25°C or transferred to 5, 10 or 15°C, all at 100% relative humidity. Low temperatures significantly reduced emergence of H. bacteriophora and significantly delayed emergence of S. carpocapsae and S. glaseri but had no effect on rate of emergence of S. feltiae. A third experiment investigated survival of S. carpocapsae within the insect cadaver at 25 and 15°C and 75% r.h. At 25°C, all infective juveniles had died by day 28. At 15°C, 28% of infective juveniles survived in the cadaver after 40 days but could only emerge after the cadavers were immersed in water for 24 h. We conclude that infective juveniles of entomopathogenic nematodes can survive adverse environmental conditions for limited periods in the host cadaver, but low temperatures and relative humidities prevent emergence and the infective juveniles eventually die.

This is the second part of a revision of the genus Basiria Siddiqi, 1959; it deals with the taxonomy of the species with four lateral lines and an anterior oesophageal median bulb. Type material of nine species of the genus and populations of several species from Iran, China, Vietnam, and Australia were examined by light microscopy. The following species are synonymized: B. conura, B. obliqua with B. duplexa, B. citri with B. berylla, and B. paratumida with B. tumida. B. ritteri is a new record for China and Vietnam, and B. berylla for Iran.
