“…According to CANGUSSU & ZUCOLOTO (1992) in studies with medfly Ceratitis capitata (Wiedemann, 1824) fruitflies, using insects reared in laboratory on artificial diets, when a nutrient (protein in this case) is offered in different concentrations, the highest ingestion occurs when the concentration is small and therefore unsatisfactory to the organism needs. This compensatory response was already studied in other insects (SIMPSON & ABISGOLD, 1985;ABISGOLD & SIMPSON, 1987;HAMILTON & SCHAL, 1988;SIMPSON et al, 1989). Studies with Anastrepha suspensa (Loew, 1873) showed that compensatory responses did not occur to hydrolyzed yeast, but they did to carbohydrates (SHARP & CHAMBERS, 1984).…”

Using artificial solid diets, experiments were performed with Anastrepha obliqua (Macquart, 1835) wild females in order to verify the influence of different quantities of brewer yeast on the performance and compensation behavior to unbalanced diets ingestion. The observed parameters were egg production, ingestion, diet efficiency and survival in the reproductive phase. Results indicated that there was no compensatory ingestion to different quantities of yeast and that the diet with 12.5g of yeast provided the best performance. The absence of compensatory ingestion is discussed based on the yeast phagostimulation and on the costs involved in solid diets ingestion. The relation between the analyzed parameters and the protein quantities in the diet were discussed.

“…Increase of ingestion is not big enough to compensate for dilution. Besides that, no direct evidence has been observed up to now that insects self-regulate ingestion for caloric sake, as it seems to happen with rats (SIMPSON & ABISGOLD 1985).…”

ABSTRACT. Adult Tephritidae, especially of the genus Al1aslrepha (Schiner, 1868), have been observed to feed on a wide variety of natural diets. The fruit on which they feed , in general, are rich in sugar content, chiefly glucose, frutose and sucrose, which are also the sugars that those insects utilise better. Neitherthe behavioural mechanisms, nor the physiological ones, that control food selection by insects, are well known. Because some of those aspects are not known for the spec ies A l1aslrepha obliqua (Macquart, 1835) either, and in order to understand their biology better, three experiments were conducted. In the first experiment, it was checked whether there was a difference in metabolic profit by those insects, when fed the carbohydrates more frequently found in nature, as resulting in a bigger egg production and higher survival rate at the end of the experiment. In the second, it was checked whether A. obliqua can regulate diet ingestion according to carbohydrate content in dry as well as wet diets. In the third experiment, measurements were made to establish the lowest carbohydrate concentration flies are able to recognise in the diet. Analysis of the data showed that ingestion of carbohydrates which are commonly found in nature, in association with a protein source, is vety well utilised by females of A. obliqua. It was also shown that _those insects are not probably able to compensate for the difference in carbohydrate content in dry diets, whereas they do so for wet diets. In relation to discrimination threshold, it seems that it is related to the higher occurrence of the carbohydrate in their normal diet, that is, they can recognise carbohydrates that are common in their natural diet better than the less frequent ones.

“…We made 24 artificial, dry diets that varied in P and C, as well as overall nutrition, based on the established protocol outlined by Simpson & Abisgold [44]. The distribution of these diets in nutritional space can be seen in the electronic supplementary material, figure S1, and the composition of these diets in the electronic supplementary material, table S1.…”

Protein and carbohydrate intake influence sperm number and fertility in male cockroaches, but not sperm viability

et al. 2015

It is commonly assumed that because males produce many, tiny sperm, they are cheap to produce. Recent work, however, suggests that sperm production is not cost-free. If sperm are costly to produce, sperm number and/or viability should be influenced by diet, and this has been documented in numerous species. Yet few studies have examined the exact nutrients responsible for mediating these effects. Here, we quantify the effects of protein (P) and carbohydrate (C) intake on sperm number and viability in the cockroach Nauphoeta cinerea, as well as the consequences for male fertility. We found the intake of P and C influenced sperm number, being maximized at a high intake of diets with a P : C ratio of 1 : 2, but not sperm viability. The nutritional landscapes for male fertility and sperm number were closely aligned, suggesting that sperm number is the major determinant of male fertility in N. cinerea. Under dietary choice, males regulate nutrient intake at a P : C ratio of 1 : 4.95, which is midway between the ratios needed to maximize sperm production and pre-copulatory attractiveness in this species. This raises the possibility that males regulate nutrient intake to balance the trade-off between pre-and post-copulatory traits in this species.
