the paper contains the first report on the biology of snail-killing flies (sciomyzidae) in khuzestan. it is based on field and laboratory studies conducted during november 1971 and april 1973, as well as field observations in may 1972, at the dezful medical research station. additional biological information obtained during studies is given for pherbellia fuscipes (macaquart), p.grisescens (mei...

The present work was carried out to investigate first, the ecology of the Sepedon flies as well as speciesof Lymnea snails and secondly, the biological effects of Sepedon fly larvae living on Lymnea. In this regard,the life cycle, death rate and compatibility of Lymnea species, as well as the life cycle of Sepedon flies inbreeding cage and the activity of the new larvae in the same ecological c...

Field-based studies and laboratory bioassays were conducted with apple maggot, Rhagoletis pomonella (Walsh), and blueberry maggot, Rhgoletis mendax Curran, flies to investigate the performance and duration of activity of insecticide-treated biodegradable and wooden spheres for control of Rhagoletis species. Four neonicotinoid insecticide treatments including imidacloprid, thiamethoxam, and thio...

the present work was carried out to investigate first, the ecology of the sepedon flies as well as speciesof lymnea snails and secondly, the biological effects of sepedon fly larvae living on lymnea. in this regard,the life cycle, death rate and compatibility of lymnea species, as well as the life cycle of sepedon flies inbreeding cage and the activity of the new larvae in the same ecological c...

Four species of Tonnoira from the Brazilian Atlantic forest are described and illustrated: Tonnoira brisolaii sp. nov, Tonnoira ferreirai sp. nov., Tonnoira andradei sp. nov. and Tonnoira galatiae sp. nov. 

We have identified endosymbiotic bacteria of the genus Spiroplasma in wild populations of Drosophila melanogaster from Ukraine. These bacteria were identified from two different locations, and this is the first finding of the bacteria in Ukraine. Flies from populations infected with Spiroplasma spp. did not show any signs of male killing. The results are discussed in relation to previous findin...

Maternally transmitted male-killing endosymbionts can exert strong and relentless selection pressure on their hosts to evolve resistance to these infections. Surveys of current infection prevalence and mtDNA diversity indicate that Drosophila innubila is and has been infected with male-killing Wolbachia at moderate frequencies for extended evolutionary periods. Here, we use coalescent simulatio...

Two new species of Psychodinae, Psychodidae, from the semi-arid region of Brazil are described and illustrated: Arisemus rubeni sp. nov. and Lepidiella olgae sp. nov. Only nine psychodid species were previously known from that region.
