RESUMO
Al estudiar los ectoparásitos de los murciélagos Phyllostomus elongatus y Stumira lilium de la Reserva Nacional de Tambopata del Departamento de Madre de Dios - Perú, se identificaron las siguientes especies de dipteros hematófagos: Trichobius caecus, T. longipes, T. parasiticus; siendo T. caecus el primer hallazgo para el país y T. parasiticus para Madre de Dios

An imported case of traumatic myiasis occurred in a soldier wounded during military action in Panama in December 1989 and evacuated to Brooke Army Medical Center, Fort Sam Houston, Texas. At the medical center, five larvae were removed from the scalp wound, reared to the adult stage, and identified as Cochliomyia hominivorax (Coquerel). Though this was the only reported case of wound myiasis of the 254 servicemen evacuated for medical treatment, this incident indicates a potential mechanism for the reintroduction of C. hominivorax into the United States.

The morphology of screwworm, Cochliomyia hominivorax (Coquerel), larval spines was affected by larval substrate and geographic effects on variation. Spine morphology of individual larvae was used to determine criteria for discrimination analysis classification. Classification criteria for types of wounds and host species were determined for larvae from central and southern Mexico. Larvae from marginal populations (United States, Caribbean Islands, Costa Rica) were classified by these criteria. Classifications were 27% accurate for wound type and 20% correct for animal species. When single egg masses were split and larvae were reared on laboratory diet and animal substrates, analysis of spine types showed significant rearing environment and sibship (egg mass) effects. Cluster analysis of geographic groups showed that larvae from central populations were closely clustered, whereas marginal groups were morphologically dissimilar from each other and from the central populations. These results indicate that larval spine morphology has limited value in taxonomic or systematic studies of screwworms and that mating compatibility was not related to spine similarity among populations. The significant differences between wound-reared and artificial media-reared larvae indicate that differences in spine morphology could be used to verify that samples from the field were indeed taken from animal wounds.

Eight species of ectoparasites were recovered from 35 Sylvilagus audubonii and 35 Lepus californicus occurring sympatrically near the Clovis-Portales area of eastern New Mexico. Recovered were Anoplura (Haemodipsus setoni), Diptera (Cuterebra lepusculi and Cuterebra ruficrus), Siphonaptera (Echidnophaga gallinacea and Euhoplopsyllus glacialis), and Acari (Ornithodoros parkeri, Dermacentor parumapertus, and Haemaphysalis leporispalustris). Jaccard's index showed a 50% ectoparasitic overlap with H. setoni, E. glacialis, D. parumapertus, and H. leporispalustris present on both host species. Cuterebra lepusculi, E. gallinacea, and Ornithodoros parkeri were taken only from S. audubonii, whereas C. ruficrus occurred only on jack rabbits. Euhoplopsyllus glacialis was the only species to demonstrate a preference for sex of host, occurring more abundantly on females.

The material of 22302 flies of Anthomyiidae, Muscidae and Calliphoridae collected by trap-method in Cuba 1966 was qualitatively and quantitatively analysed. Relative density, seasonal incidence and food preference were ascertained in 20 species. In potential vectors of human diseases the ecological characters and classification of synanthropy are given.
