Abstract
In this study, the effect of water on growth (wet weight gain), food consumption, feces quantity, digestive activity and glycogen level of Gryllus bimaculatus female adults was investigated by doing the experiments of feeding and starvation. Wheat bran was given for feeding. All parameters were found to be significantly higher in insects feeding with water than those feeding without water. A significant difference did not occur in mean wet weight and glycogen level in insects either feeding without water or starved for one week. At the end of the experimental period, a wet weight gain (43%) was observed only in the insects feeding with water, and the highest loss (40%) in wet weight in those starved without water until death. Similarly, mean glycogen content was highest (1.108 mg) in the former, and the lowest (0.058 mg) in the later. In terms of parameters studied, it was concluded that water has a significant effect on G. bimaculatus females.
Özet
Bu çal›flmada, beslenme ve açl›k deneyleri yap›larak suyun, Gryllus bimaculatus ergin diflilerinin büyüme (canl› a¤›rl›k art›fl›), besin tüketimi, d›flk› miktar›, sindirim etkinli¤i ve glikojen düzeyi üzerine etkisi araflt›r›ld›. Beslenme deneylerinde böceklere kuru bu¤day kepe¤i verildi. Çal›fl›lan tüm parametrelerin, su verilerek beslenen böceklerde su verilmeden beslenenlere göre belirgin olarak daha yüksek oldu¤u saptand›. Bir hafta süreyle su verilmeksizin gerek beslenen gerekse aç b›rak›lan böceklerin canl› a¤›rl›k ve glikojen düzeylerinde önemli bir farkl›l›k ortaya ç›kmad›. Deney süreci sonunda, canl› a¤›rl›k kazanc›, yaln›zca su verilerek beslenen böceklerde (%43), canl› a¤›rl›k kayb› ise en fazla, su verilmeksizin ölünceye dek aç b›rak›lan böceklerde (% 40) oldu. Benzer flekilde, glikojen miktar› sözü edilen ilk grupta en yüksek (1.108 mg), di¤er grupta ise en düflük (0.058 mg) olarak saptand›. Elde edilen bulgular suyun, G. bimaculatus ergin diflilerinde çal›fl›lan parametreler üzerine belirgin bir etkisi oldu¤unu göstermektedir.
