Published 1989Staff ViewISSN: 1365-3083Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicineNotes: Amyloid subunit proteins related to the λ IV subgroup of immunoglobulin light chains have not been previously reported. We have determined the amino acid sequence of an AL amyloid protein BAK and shown that it has the structure typical of λ IV light chain proteins. This protein, which was isolated from the spleen of a patient with AL amyloidosis, has 111 residues in the variable domain and also includes the first tryptic peptide of the constant domain for a total of 130 residues. Comparison of the primary structure of this protein with the only other completely characterized λ IV protein (SH) reveals that they are highly homologous with only one amino acid change in FR1, two changes in FR2, and one change in FR3. The CDR regions also show few changes, with only three in CDR1, one in CDR2, and five in CDR3. To test the hypothesis that the formation of AL amyloid is related to changes in the FR regions which could affect molecular aggregation, the structure of BAK was compared with the myeloma protein SH with respect to the presumed tertiary structure. Only limited amino acid substitution was found in the surface positions that might affect intradimer and interdimer aggregation. These included an isoleucine for leucine change at position 43 and phenylalanine for valine at 45, which may affect intradimer interaction and a change of histidine to asparagine at position 67.Type of Medium: Electronic ResourceURL: -

ISSN: 1570-7458Keywords: fecundity ; host plant quality ; Pistia stratiotes ; Spodoptera pectinicornis ; nitrogen ; trichomes ; oviposition ; biological control of weedsSource: Springer Online Journal Archives 1860-2000Topics: BiologyNotes: Abstract We determined the influence of larval host quality of the floating aquatic weed Pistia stratiotes L. (Araceae) on the fecundity and egg distribution of the biological control agent Spodoptera pectinicornis (Hampson) (Lepidoptera: Noctuidae). Different nutritional levels were produced by growing plants with relatively low and high levels of nitrogen, phosphorus and potassium fertilizer. Female and male pupal biomass were significantly greater when the larvae were fed leaves from the high fertilizer plants. Although the fertilizer treatments did not significantly influence total fecundity, there was an indirect effect as adults from larger pupae were more fecund. Regardless of treatment, ovipositing females formed a depression in the leaf surface by removing trichomes into which they deposited the egg masses. Most of the egg masses were laid on the lower leaf surface, on leaf positions 5–8 (counting from the young inner to the outer leaves) and during days 1–2 post-eclosion. Most of the eggs were laid in masses but about 12% were solitary. Females fed the low fertilizer treatment laid a greater proportion (mean ± s.e.) of their eggs as solitary eggs (17.3 ± 3.4% of total eggs) than did females fed the high fertilizer treatment (8.3 ± 2.3% of total eggs). The increased percentage of solitary eggs laid by the females from the low quality larval diet may be an adaptive response to decrease competition among the progeny.Type of Medium: Electronic ResourceURL: -

ISSN: 1570-7458Keywords: Allelochemical ; caffeine ; compensatory feeding ; costs ; diet dilution ; nutritional ecologySource: Springer Online Journal Archives 1860-2000Topics: BiologyNotes: Abstract Many herbivores increase their consumption rate as dietary nutrient concentration declines. This compensatory response can mitigate the fitness-lowering impact of reduced food quality, but little is known about its costs. In this study we tested the hypothesis that one cost to a faster consumption rate can be the ingestion of a toxic dose of an allelochemical occurring in the food. We fed velvetbean caterpillars a diet with progressively diluted nutrient levels but containing the same concentration (% fresh mass, fm) of caffeine, a methylxanthine alkaloid. Larvae compensated for the reduced nutrient level, with those fed the most diluted diet increasing their biomass-relative consumption rate (fm) 2.6-fold over larvae fed the undiluted diet. Consequently, their rate of caffeine ingestion increased to a pharmacologically effective dose, interfering with food utilization, slowing growth, reducing subsequent feeding and lowering survival. These results suggest that greater allelochemical ingestion can be one cost of an increased consumption rate, although additional studies with other allelochemicals and species are necessary to more broadly evaluate whether insects can adaptively balance their intake of nutrients and allelochemicals through adjustments in consumption rate. In addition, these results highlight the importance of measuring consumption rates of allelochemicals and other ingested biocides, not just their dietary concentration, when assessing efficacy against herbivores.Type of Medium: Electronic ResourceURL: -

ISSN: 1572-8889Keywords: Oxyops vitiosa ; Melaleuca quinquenervia ; Solenopsis invicta ; predation ; chemical defense ; Curculionida ; MyrtaceaeSource: Springer Online Journal Archives 1860-2000Topics: BiologyNotes: Abstract The larvae of the leaf-feeding weevil Oxyops vitiosa, a biological control agent of Melaleuca quinquenervia, are covered with a viscous orange coating that is thought to protect against generalist predators. This coating is gradually lost as the larvae drop to the ground and pupate in subterranean pupal cells. To test the antipredator activity of this species, four immature life stages (early instars, late instars, prepupae, pupae) were exposed to a common generalist predator, the red imported fire ant Solenopsis invicta. Choice tests were conducted by placing an O. vitiosa individual and a control larva of the weevil Neochetina eichhorniae into an arena containing a S. invicta colony and observing subsequent ant behaviors. S. invicta workers contacted O. vitiosa early instars, late instars, and prepupae less frequently than control N. eichhorniae larvae, and upon contact S. invicta was less likely to behave aggressively toward these O. vitiosa life stages than toward N. eichhorniae larvae. However, S. invicta contacted, attacked, and consumed naked (nonencased) O. vitiosa pupae and N. eichhorniae larvae with equal frequency. Encased O. vitiosa pupae buried in sand were not attacked compared to susceptible encased pupae on the sand surface. By shifting from a chemical defense during the larval stages to a physical defense during the pupal stage, O. vitiosa reduces the risk of attack by this generalist predator.Type of Medium: Electronic ResourceURL: -
