“…The results of Pappas & Fraenkel (1977) -that protein is needed to trigger the onset of vitellogenesis --would predict that there would be a peak in protein intake on the 3rd or 4th day, but this seems only demonstrable under the conditions described by Dethier (1961) and Belzer (1978). Neither Rachman (1980) offering single drinks to S and SY flies, nor Greenberg & Stoffolano (1977) repeating the experiments of Dethier (1961) but with a light/ dark cycle, was able to demonstrate such a peak. Nor was there any peak in the olfactory response under the conditions of the experiment described here --not even by the protein-deprived flies.…”

EFFECT OF AGE AND NUTRITION ON THE RESPONSES OF FEMALE BLOWFLIES (PHORMIA REGINA) TO THE ODOUR FROM A PROTEINACEOUS SOURCE

Female blowflies that had been fed either sucrose (S flies) or sucrose and yeast (SY flies) were tested individually for their responses to the odours from a range of concentrations of yeast. They showed a cyclical change in responsiveness. S flies were most responsive at 5 and 6 days old. SY flies were most responsive at 5, 6 and 8 days old. General levels of activity of the flies in the absence of specific odours did not show a cyclical change. The ages of greatest responsiveness corresponded with the days which would precede egg laying.

“…Only ecdysterone is able to induce the typical female characteristics in the ultrastructure of the fat body of males (Stoppie et al, 1981). As oestrogens influence some aspects of behaviour in vertebrates, we examined a few specific behavioural characteristics in Sarcophaga as related t o ecdysterone and reproduction, particularly protein ingestion, It has been well documented that, in order t o complete vitellogenesis, anautogenous flies require a protein meai (Fraenkel;1940;Dethier, 196 1 ;Strangways-Dixon, 196 1 ;Greenberg & Stoffolano, 1977). In female Diptera protein consumption is generally higher in males.…”

In Sarcophaga bullata and other blowflies, the low haemolymph ecdysteroid titre is responsible for the inability of males to synthesize vitellogenin, although they have the genes coding for this protein. The high moulting hormone titre in females is of crucial importance for vitellogenesis. In this context we investigated whether the difference in protein ingestion between the sexes might also be related to differences in ecdysteroid titre. Using a two-choice system, we observed that upon addition of ecdysterone to the food, protein ingestion increased in males. Topical application ofmethoprene also had a stimulatingeffect. Prolonged treatment with ecdysterone reduced thecopulatory behaviour of males.

“…Both sexes obtain their protein in the Þeld by eating feces ), thus both are capable of carrying pathogens to food. Greenberg and Stoffolano (1977) showed that females have a greater total daily mean intake of carbohydrates with respect to age, and because of this added confounding effect of increased nutrient demand, whether carbohydrates or protein, for egg development by the female, only 4-d-old adult male ßies were used to conduct experiments. Day of emergence was deemed day 1.…”

Effect of High and Low Concentrations of Sugar Solutions Fed to Adult Male, Phormia regina (Diptera: Calliphoridae), on ‘Bubbling’ Behavior

‘Bubbling’ behavior, or the regurgitation of liquid from the crop through droplet formation on the proboscis, has been observed in many nonblood feeding dipterans. One factor that has been identified as a cause for ‘bubbling’ is the concentration of the solution flies ingest. The hypothesis presented in this paper states that male flies ingesting more dilute solutions will exhibit more bubbling behavior than those that ingest a less dilute solution. Concentrations tested were a high concentration of 80% sucrose solution and a low concentration of 20% sucrose solution. Males only were tested to avoid any confounding effect of the females need for energy sources for reproduction. Male flies that ingested the 80% sugar solution showed 45% of the flies tested bubbling, which was significantly different from the flies that ingested 20% solution, which had only 5% of the flies bubbling. No significant weight loss or percentage of weight loss was observed between bubbling and nonbubbling flies for either sugar solution concentration. Results comparing a high and low concentration of sucrose do not support the theory of elimination of excess water loss to concentrate dilute solutions or the “dilute solution hypothesis”. Other factors, not identified previously, that could contribute to bubbling, are changes in osmolality, utilization of blood sugar (i.e., trehalose), and the regulation of the proventricular valve.
