Biological control of mosquitoes with mermithids.
Mermithid nematodes parasitizing mosquitoes have substantial potential for vector control. Studies on the physiological ecology of Romanomermis culicivorax have defined some of the general requirements of mermithid nematodes and produced general guidelines for the experimental release of mermithids in biological control. Experimental field studies have established the biological control potenti...
متن کاملCarbohydrate-mediated Recognition of Larval Mosquito Hosts by Romanomermis culicivorax.
Proteases, glycosidases, and lectins were tested and the results supported a role in host recognition for glycoproteins containing beta-glucose and alpha-mannose on the cuticular surface of host and parasite. Carbohydrates containing alpha-glucose, galactose, fucose, or N-acetylglucosamine residues apparently are not involved in nematode attachment. Chitin or a related N-acetylglucosamine polym...
متن کاملComparative Susceptibility of Larval Mosquitoes Exposed Separately by Instar or in Mixed Populations to the Nematode Romanomermis culicivorax.
The mermithid nematode Romanomeris culicivorax has been released many times to control natural populations of larval mosquitoes. Generally, infection levels resulting from such releases were highest in secondand third-instar and lowest in first-instar hosts when all instars were present in the habitat (1,3). This contrasts sharply with well.established results from laboratory studies which show...
متن کاملGlyoxylate Pathway in the Free-Living Stages of the Entomophilic Nematode Romanomermis culicivorax.
Isocitrate lyase and malate synthetase, key enzymes of the glyoxylate cycle, were present in postparasites of the mermithid nematode Romanomermis culicivorax. Specific activities of enzymes were higher in adult postparasites than in newly emerged juveniles. Isocitrate lyase had a well-defined pH optimum (7.5), whereas malate synthetase functioned optimally over a broad range of alkaline pH (7.5...
متن کاملSequence amplification and gene rearrangement in parasitic nematode mitochondrial DNA.
The nematode Romanomermis culicivorax, an obligate mosquito parasite, possesses a 26 kilobase (kb) mitochondrial genome. The unusually large size is due to transcriptionally active DNA sequences present as 3.0 kb direct tandem repeats and as inverted portions of the repeating unit located elsewhere in the mitochondrial DNA (mtDNA). The genome rearrangements involved in establishing this unusual...
