“…The parasitoid Diglyphus isaea Walker (Hymenoptera: Eulophidae) was able to use sucrose and convert it to glycogen and body sugars, but it could not convert it into lipids (Zhang et al, 2011). Many parasitoid species are not able to synthesise lipids from carbohydrates (Akman Gündüz et al, 2010;Olson et al, 2000;Rivero & West, 2002;Zhang et al, 2011), and parasitoids emerge with a considerable reserve of lipids that decrease with age (Akman Gündüz et al, 2010).…”

The wheat stem sawfly, Cephus cinctus Norton (Hymenoptera: Cephidae), is a major pest of wheat grown on the Northern Great Plains and Canadian Prairies of North America, causing economic losses of as much as $350 million annually. Two species that parasitize wheat stem sawfly larvae in wheat stems are Bracon cephi (Gahan) and B. lissogaster Muesebeck (Hymenoptera: Braconidae). Carbohydrate‐rich diets increase adult parasitoid longevity and reproductive parameters, enhancing their success as natural enemies. In previous studies, these species had increased longevity, egg load, and volume when fed sucrose solutions, encouraging further research on their nutritional needs. Therefore, we conducted experiments with artificial diets using adult females fed sucrose, glucose, and fructose solutions. Females were also fed these sugars in combination with a mixture of amino acids. We assessed individuals daily for longevity. Both species benefited from diets containing carbohydrates, with an increase in longevity from an average of 9 to 51 days for B. cephi, and from 6 to 34 days for B. lissogaster. Additional experiments assessed egg load and volume after 2, 5, and 10 days of cumulative feeding in B. cephi. These females produced 1.4‐fold more eggs when fed amino acids, 2.5‐fold more with sugar, and 2.7‐fold more when fed sugar with amino acids. They had a 1.3‐fold increase in egg volume when fed amino acids, 1.9‐fold with sugar, and 2.1‐fold when fed sugar with amino acids. Our study reveals the nutritional requirements of these braconid parasitoids and the benefits of nutritional sources when implementing conservation biological control strategies.

The effects of carbohydrates and tannen on the development and food preferences of Uresiphita gilvata larvae were investigated in this study. In addition, with the addition of tannin, the importance of plant-herbivore co-evolution in the food choice of the larvae was mentioned. For this reason, thirteen different artificial diets were prepared. Each diet contains sucrose, glucose, galactose, maltose, fructose, arabinose, mannose, or starch at the same concentration. To investigate the effect of tannic acid, 5 % tannic acid was added to the diets each containing sucrose, starch, glucose or maltose at the same concentration. According to the results of the study, sucrose was consumed by larvae more than glucose and fructose. However, the maximum food consumption of U. gilvata larvae was on the diet containing arabinose and their minimum consumption was on the diet containing mannose. Galactose is more consumed by larvae. However, intake galactose can not converted to pupal lipid by larvae. The addition of tannin to the diet reduced the amount of consumption of diet the dry pupal weight and lipid amount of pupae. However, the addition of tannin to the diet increased the amount of protein and extended the development time of pupae.
