“…The hexane extract of wheat germ, the subsequent extract \vith 80% ethanol in water, and the residue after extraction were tested alone and in all possible combinations relative to controls. These three wheat germ components were expected to contain, respectively, the lipids, sugars, and protein (see Joslyn 1970). All 28 possible comparisons among these eight treatments were done experimentally (three replications per test).…”

A starch formulation of Bacillus thuringiensis Berliner is being developed as a component in a pest management system to control Ostrinia nubi/alis (Hubner). Palatability is one property of starch formulations which must be investigated; this study was done to identify materials that will cause O. nubi/alis larvae to feed readily on starch granules. A two-choice behavioral bioassay was developed for evaluating phagostimulants in starch granules (without B. thuringiensis). Various materials were tested: compounds reported in the literature as feeding stimulants, the artificial diet for the species, corn foliage, corn oil, and the commercial feeding stimulant, Coax. Starch granules without additives were seldom fed upon by larvae, but it was possible to make the granules even more acceptable to larvae than corn foliage. The best feeding responses were to mixtures containing lipid, sugar, and protein. Coax was the most effective material tried; for example, in bioassays, the ratio of larvae that chose granules with Coax over those with only starch was 320:1, and the ratio of larvae choosing granules with Coax over corn leaf disks was 11.5:1. In greenhouse tests, phagostimulants increased the effectiveness of granules containing B. thuringiensis for killing O. nubilalis larvae. For example, when Coax was added to the granules, the amount of B. thuringiensis used could be reduced by 75% without reducing mortality.

“…Five replicate subsamples of each dried and ground food type were analysed for lipid content using a petroleum ether solvent in a Soxhlet apparatus (Bligh & Dyer, 1959;Joslyn, 1970). Following drying at 60" C for 24 h, and 1 week in a desiccator, samples were reweighed and the weight lost during extraction was assumed to be lipid.…”

The evacuation patterns of shrimp, crab and fish from the stomachs of black and yellow rockfish, Sebustes chrysomelas, were examined by feeding meals of known size and measuring the amount remaining after various post-prandial intervals. Linear, square-root, exponential, power exponential, logistic and Gompertz models (the latter two with unrestricted lower asymptotes, or with lower asymptotes restricted to 0% food remaining) were fitted to the wet weight, dry weight and volume of food remaining in the stomach as a function of post-prandial time. Evacuation patterns ranged from steeply concave (fish wet weight, dry weight, volume, shrimp dry weight), to linear (shrimp wet weight, crab dry weight), to highly convex with lag phases of up to 30 h (crab wet weight, crab and shrimp volume). Friability, the ease with which a food item is fragmented in the stomach, may be an important factor in determining evacuation patterns. The evacuation of a crab meal by tagged, free-ranging S. chrysomelas in the field was not significantly different from that of S. chrysomelus held in the laboratory.
