| lanceimermis palustris n. sp. and telomermis palustris n. sp. (nematoda: mermithidae) parasites of chironomid (insecta: diptera) adults from lake alice bog in northern minnesota. | in the summer of 2003, chironomid imagoes eclosing from lake alice bog in minnesota yielded mermithid nematodes of 2 new species. lanceimermis palustris n. sp. is distinguished from the other 14 species of the genus by the subventral mouth position, thinness of the hook-shaped spicule, body index, and structure of the male tail muscles. telomermis palustris n. sp. is distinguished from the only other species of the genus by the structure of the amphids, body length, maximum body width, length of ... | 2004 | 15715243 |
| laboratory infection of blackflies (simuliidae) and midges (chironomidae) by the mosquito mermithid, romanomermis culicivorax. | penetrating infective juveniles of romanomermis culicivorax usually killed first-stage larvae of chironomus maturus johann., chironomus sp., simulium damnosum theo., and s. venustum say. nematodes were melanized and died after they entered fourth stage larvae of 2 chironomid species, but no host reaction was evident after entry into fourth-stage blackfly larvae. in contrast, the nematodes initiated development in the latter hosts, which died before the nematodes completed their development. | 1979 | 512756 |
| <i>chironomus</i> <i>alchichica</i> sp. n. (diptera: chironomidae) from lake alchichica, mexico. | morphological analysis of all developmental stages (except female), mitochondrial dna sequences from cytochrome c oxidase subunit i (cox1) and cytological analysis of the polytene chromosomes were used to describe a new species of chironomus found in the littoral and profundal zones of an endorheic, warm-monomictic lake in mexico. male imago is distinguished by the shape of superior volsella and by an antennal and bristle ratio lower than two. the pupa is characterized by the spur morphology of ... | 2017 | 29245369 |
