Ecdysis in insects can be defined as shedding of the cuticle at the end of a larval stadium. This event can only occur after the peak titer of ecdysteroid in the hemolymph has returned to a low level. In the cockroach Periplaneta americana, ecdysis i

Injection of 0.1 pmol of the octapeptide Peram-AKH II (pGlu-Leu-Thr-Phe-Thr-Pro-Asn-TrpNH(2)) elicits a significant hypertrehalosemic response in the American cockroach, Periplaneta americana; a maximal effect is obtained with 1pmol. The latter amoun

The effect of the hypertrehalosemic hormones, HTH-I and HTH-II, on free fatty acid levels in trophocytes prepared from Periplaneta americana fat body by collagenase treatment was investigated. Following a challenge from either of the hormones the con

Trophocytes from the disaggregated fat body of the cockroach ( Periplaneta americana ) respond to synthetic hypertrehalosemic hormone (HTH) by increasing the rate of trehalose synthesis. The cells give a similar response when incubated with stearic,

A method has been developed for disaggregating the fat body of the adult American cockroach, Periplaneta americana, using collagenase. The yield of cells is sensitive to the osmolarity of the dispersing medium and to the age of the cockroaches from w

The glucosidase inhibitor 1,4-dideoxy-1,4-imino-D-arabinitol (DIA) was used to investigate the action of hypertrehalosemic hormone (HTH) on carbohydrate, neutral lipid, and phospholipid metabolism in the hemolymph and fat body of the cockroach, Perip

The hypertrehalosemic hormones Pea HTH-I and Pea HTH-II have a lipogenic effect in the cockroach, Periplaneta americana . This has been determined by measuring the change in tri-, di-, monoacylglycerol, phospholipid and free fatty acids in the hemoly

Recently, synthetic HTH-I and HTH-II have been shown to increase the formation of free fatty acids in cockroach (Periplaneta americana) fat body. In this study we show that HTH-II increases PLA(2) activity in dispersed trophocytes, thus implying that
