| a new host, simulium argyreatum meig., for the cytoplasmic polyhedrosis virus of blackflies in czechoslovakia. | the cytoplasmic polyhedrosis virus (cpv) from the midgut of blackfly larvae is recorded from a population of simulium argyreatum in czechoslovakia. a 7.7% infection of 2766 sampled larvae was manifested by white spots in their body. 85% of the white-spotted larvae were infected with cpv when sampled in june. in august 9% of 1377 larvae had white spots but only 10.6% of them were with cpv. out of 823 collected pupae, only 3 imperfect pupae had the virus in apparent form. other infections producin ... | 1978 | 369963 |

| [b chromosome polymorphism of blackflies (diptera, simuliidae) from the north-western region of russia]. | we have studied karyofonds of natural populations and b-chromosome morphology of 8 species of blackflies from the north-western region of russia: odagmia ornata mg., hellichiella crassa rubz., simulium morsitans edw., simulium argyreatum mg., shoenbaueria pusilla fries., cnetha fontinalis radzv., stegopterna duo-decimata rubz., and archesimulium tuberosum lundstr. for this purpose we made slides of squashed blackflies larvae with salivary gland polytene chromosomes stained by aceto-orcein, in ad ... | 2006 | 16805316 |
| [water mite (sperchontidae) parasitism on blackflies (simuliidae)]. | in small streams of donbass on pupae of black flies odagmia ornata mg. and chelocnetha angustitarse lundstr. occur the larvae of water mites sperchon setiger s. thor. and sperchonopsis sp. n. which pass from pupae to imago during the emergence. the infection extensiveness of adult black flies amounted on the average to 18--20% and intensiveness-- to 1--7 larvae. larvae of water mites were not recorded from pupae and imago of simulium argyreatum mg. and of the genus wilhelmia. under laboratory co ... | 2007 | 7465245 |
