Title: Effect of a hyperglycemic factor on haemolymph trehalose and fat body carbohydrates in the American cockroach
Abstract: Effects of the hyperglycemic factor on haemolymph trehalose and fat body carbohydrates have been investigated in adult male cockroaches. Injection of an aqueous extract of the corpus cardiacum into intact and beheaded coackroaches caused a rapid and sustained rise in the haemolymph trehalose level. A linear dose-response relation was obtained over a wide range of doses. Concomitant with the increase in haemolymph trehalose, fat body glycogen decreased, accompanied by a temporary increase in fat body trehalose. Injection of distilled water or saline, or anaesthetization itself caused a significant rise in haemolymph trehalose level, but the effect was temporary. These results are discussed in relation to the regulation of carbohydrate metabolism in the insect.
