Digestibility and nutrient composition of foodstuffs, be they plant or not, and the nutritional requirements of insects vary. The qualitative nutritional requirements among insects are quite similar. Therefore, qualities of foodstuff as measured by its ability to promote or support growth, etc. depend on how well the nutrient composition of foodstuff made available by digestion fits the nutritional requirements of the insect. This is better seen using synthetic diets rather than plants. From such investigations it is found that, provided all essential nutrients are present, the proportions of essential nutrients in a foodstuff contribute more to nutritional quality than do the absolute amounts of nutrients. Thus, nutrient balance per se can affect: rate of food consumption and efficient utilization; parasites with respect to host food; rate of growth and development as such, and with respect to temperature; and food selection in an insect.The purpose of this paper is to draw attention to quantitative factors of nutritional importance, especially the proportions of nutrients in foodstuff. These factors are concerned with the nutritional qualities of insect foodstuff, be it plant or any stuff used as food, and their effects are measured by the ability of the foodstuff to promote or support growth, development, survival and reproduction of an insect. For insects have to obtain specific essential food substances, or nutrients, which are needed as nutritional requirements for body material and energy to do all the things attributed to life. But though food abundance is generally recognized as one of the major biotic factors regulating the numbers and population fluctuations of insect species, the nutritional qualifies of the foodstuff are not given due consideration in these matters. This paper will concern plants, for nutritionally important substances are basic to insect/food-plant relationships, and is important because about half of the known species of insects feed on plants.However, the usefulness of plants to show such nutritional matters is severely limited for various reasons (Beck, 1956; Friend, 1958;Auclair, 1958; House, 1961). And in no case have the,, nutritional requirements of a phytophagous insect together with the digestibility and nutritive composition of its food plant been determined completely enough for the purpose at hand. But synthetic, or chemically defined, diets have been used that permitted the physical and chemical properties of the foodstuff, including its digestibility, to be kept uniform and the nutrient

“…The results presented in this review on the multiple-choice tests, in which aphids were allowed to choose between diets of different chemical compositions, such as different sucrose or total amino acid level, or diets of various pH values, bear importantly on a principle discussed recently by House (1967), a principle supported by pertinent tests with Pseudosarcophaga affinis Falldn. This principle states that nutrient composition of a foodstuff can be responsible for food selection by an insect.…”

“…Reproduction was also impaired. Cysteine and methionine were apparently independently required, suggesting that this aphid lacked the cystathionine pathway described in mammals and some insects, and which allows the sparing of cysteine by methionine and vice versa (Meister, 1957;House, 1965). Both D-and L-methionine were utilized but only L-cysteine.…”

“…Since all insects so far studied were shown to have a stringent dietary requirement for some sort of sterol, usually cholesterol (House, 1965), it is surprising to note that chemical diets able to sustain aphid life indefinitely do not contain any sterol, or for that matter, any form of lipid. On that point, Dadd & Mittler (1966) surmised that the dilution factor for original reserve sterols would be, in the 20th generation, of the order of 1220.…”

Nutrition of Plant‐sucking Insects on Chemically Defined Diets

With the advent of suitable techniques for rearing plant-sucking insects, especially aphids, on chemically defined diets, knowledge of their nutrition has evolved considerably over the past 7 years. Thus, contrary to some earlier beliefs, the nutritional requirements of plantsucking insects have been found to be, with minor exceptions, generally similar to those of other insects, and it is now possible to sustain aphid colonies on artificial diets for two or more generations, and in some cases, for an almost indefinite period of time.A discussion is presented on the comparative requirements of aphids and other Hemiptera for the main classes of nutrients and for individual compounds, both on a qualitative and quantitative basis, and on the relative importance of symbiotes in the nutrition and metabolism of these insects. Some nutritional and related factors that may influence feeding behaviour will be examined, such as the influence of the pH of the medium, the light, the quality of the diet and the concentration of certain nutrients on feeding preferences by aphids. Correlations will be attempted on the significance of these findings in relation to parasite-hostplant relationships.The main subject of the entire paper will be centered on the nutrition of about half a dozen species of aphids, but some examples will be given using other plant-sucking insects.
