“…A low content of fructose in the honeydew of C. hesperidum may result from a metabolic specificity of this insect. Ashford et al (2000) report a different sugar metabolism in aphids. They suggest that the fructose moiety of ingested sucrose seems to be very efficiently and preferentially respired by the aphid, while the glucose moiety is incorporated into disaccharides.…”

“…The process of honeydew production is welldocumented but most publications focus on aphids (Ashford et al, 2000;Fischer & Shingleton, 2001;Wool et al, 2006) and little is known about this process in scale insects. According to the literature, honeydew composition differs not only among aphid species but also within aphid species depending on host plant (Fischer & Shingleton, 2001).…”

Abstract. Plant chemical composition is an important determinant of host plant-insect interactions. For many insects sugars are the main factors determining the acceptability of a plant. This study investigated changes in plant chemical composition and differences in sugar composition of different host plants induced by the feeding of Coccus hesperidum L. (Hemiptera: Sternorrhyncha: Coccoidea). Present in plant extracts and honeydew there were three monosaccharide sugars: glucose, fructose and arabinose, and one disaccharide -sucrose. Arabinose was only found in extracts of Ficus benjamina plants. The sugar content of the honeydew was greater than in the extracts of control plants and lower than that in the extracts of infested plants. The honeydew collected from C. hesperidum feeding on the three plant species differed significantly in sugar content. Extracts of coccid infested plants of the three species used in this study contained more sugar than the un-infested control plants. The results show that honeydew composition of scale insects differ and the differences reflect the chemical composition of the host plants.

“…The chromatography/electrophoresis plates were exposed to Kodak X-ray film for 4-6·weeks, and radioactive spots were identified by comparison with authentic compounds. The identification of the sugars, sugar alcohols and amino acids was verified by reverse-phase HPLC using the procedures of Ashford et al (2000) and Karley et al (2002).…”

SUMMARYDinoflagellate algae of the genus Symbiodinium in symbiosis with marine animals release much of their photosynthetic carbon to the animal host. The compounds translocated to the host (`mobile compounds') were investigated by metabolite comparison as follows: a substrate was identified as a candidate mobile compound when comparable profiles of metabolites were generated from host metabolism of this substrate (supplied exogenously) and the endogenous mobile compounds. When the sea anemone Anemonia viridis was incubated with NaH14CO2 under photosynthesizing conditions, most of the radioactivity in the animal tissue was recovered from the low-molecular-mass fraction and distributed in the ratio 1:2:1 between the neutral, acidic and basic sub-fractions. Prominent 14C-labelled compounds included glucose, malate and glucose-6-phosphate. When the symbiosis was incubated with 14C-labelled glucose plus succinate or fumarate(but none of eight other substrate combinations tested), the 14C-labelled metabolites closely matched those obtained with NaH14CO2. These data suggest that glucose and succinate/fumarate (or metabolically allied compounds) may be important photosynthetic compounds transferred from the Symbiodinium cells to the tissues of A. viridis. Metabolite comparisons can be applied to study nutritional interactions in symbioses involving photosynthetic algae and, with appropriate modification, other associations between microorganisms and plants or animals.

“…Phloem-feeding insects assimilate only a proportion of the ingested sugar, after hydrolysis by the gut sucrase to its constituent monosaccharides (Rhodes et al, 1996;Ashford et al, 2000). In aphids, the osmotic pressure of the remaining sugar (which is voided in honeydew) is reduced by a gut transglucosidase, which catalyses the polymerisation of the monosaccharide, especially glucose, into oligosaccharides in the gut Walters and Mullin, 1988;Rhodes et al, 1997;Wilkinson et al, 1997;Ashford et al, 2000). In this way, aphids avoid losing water from their body fluids, especially their haemolymph, to the gut.…”
