Carbohydrate-mediated Recognition of Larval Mosquito Hosts by Romanomermis culicivorax.
نویسندگان
چکیده
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 polymer was found in R. culicivorax preparasites. Treatment of preparasites with neuraminidase, which hydrolyzes sialic acids, increased nematode attachment to Anopheles freeborni larvae.

Comparative 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...

The ability of Romanomermis culicivorax preparasites to penetrate and infect Psorophora columbiae decreased substantially after ca. 28 hours. Parasitism at temperatures typical of Louisiana rice fields (i.e., 26, 29, and 32 +/- 0.5 C) showed a significant linear decrease (P < 0.01) as the percentage of older larval instars increased at the times of exposure. These data emphasize the need for a ...

Biochemical analyses of total protein, lipid, carbohydrate, DNA, amino acid, and length, width, and dry weight measurements are reported for different stages of Romanomermis culicivorax cultured in the mosquito, Culex pipiens. The Bradford technique for assaying total protein was the most sensitive and reliable biochemical technique tested for assaying in vivo growth of R. culicivorax. Increase...

were significantly lower than in second or third instars and about the same as for the fourth instars. Infection levels of firstand fourth-instar larvae exposed in mixed larval stages were significantly different (P < 0.05) than first and fourth instars exposed alone under similar conditions, whereas differences were not significant for secondand third-instar larvae. These data clearly indicate...
متن کاملCaudal Papillae in Romanomermis culicivorax.
Distribution of caudal papillae in adult Romanomermis culicivorax was determined by scanning electron microscopy. Ninety eight caudal papillae, each containing one pore, were present in males but absent in females. Papillae were arranged in three longitudinal rows, one ventral, two ventrolateral; the middle ventral row bifurcated anterior to the spicule. The appearance of the papillae was diffe...
