Effects of long-term cardiatectomy-allatectomy on mitochondrial respiration in the cockroach, Blaberus discoidalis [PDF]

Journal of Insect Physiology, 1969
Abstract A biochemical relationship is described between the corpora cardiaca and fat body mitochondria of Blaberus discoidalis Serv. Polarographic measurements reveal that both fat body homogenates and mitochondria from 30-day cardiatectomized-allatectomized males consume oxygen at significantly lower rates than controls.

Some effects of allatectomy in the female tsetse, Glossina austeni

Journal of Insect Physiology, 1976
The effects of juvenile hormone on the milk gland, ovaries, and fat body of adult female G. austeni were studied by allatectomy and hormone replacement therapy. In the absence of juvenile hormone, milk synthesis is slow, leading to the production, in a few cases, of small larvae over a prolonged inter-larval period.

The effect of allatectomy on the blood trehalose in the female housefly, Musca domestica L

Comparative Biochemistry and Physiology A, Comparative Physiology, 1973
Abstract 1. 1. After allatectomy, the blood trehalose concentration in the female housefly increased steadily from 33 μg/μl of blood on the first day to 48·6 μg/μl on the fourth day. 2. 2. In the sham-operated flies blood trehalose concentration fluctuated considerably and was lower. 3. 3.

Physiology of the Honeybee Corpora Allata 3. A New Method for Allatectomy of Queens

Journal of Apicultural Research, 1974
SummaryA new method for allatectomy of queen honeybees is described. This technique makes it possible to carry out the allatectomy in the air instead of under physiological solution. After allatectomy, three young queens lived for 22, 35 and nearly 50 days, respectively, and during this time they laid eggs; the two longer-lived queens showed a fairly ...

Delayed allatectomy and feeding in phormia regina (MEIG.): Effects on follicular development

The Journal of Experimental Zoology, 1975
AbstractA delay in feeding a protein meal to the female blowfly following allatectomy results in inhibition of follicular development in the previtellogenic stage. On the other hand, a protein meal given immediately after the operation permits 55% of the flies to deposit yolk in their oocytes.

The mechanism of compensation in juvenile hormone synthesis following unilateral allatectomy in Diploptera punctata

Journal of Insect Physiology, 1981
Abstract Following unilateral allatectomy in the viviparous cockroach, Diploptera punctata , the remaining corpus allatum (CA) can synthesize juvenile hormone (JH) at rates equal to that of a pair of control CA. A single CA undergoes changes in volume and cell number similar in magnitude to those occurring during the normal cycle of JH synthesis ...

The effect of allatectomy on glycogen metabolism in the fat body of the female Housefly, musca domestica L.

Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1974
Abstract 1. 1. The influence of endocrine factors on the glycogen metabolism of the fat body of the housefly during oogenesis has been studied. 2. 2. When the corpus allatum-cardiacum complex was removed, the glycogen level in the adult fat body remained lower on a fat body dry weight basis, and the ability to incorporate U-14C glucose into ...

Allatectomy and flight performance in maleLocusta migratoria

Journal of Comparative Physiology □ B, 1975
Flight performance in locusts is a function of age, with its peak value at 18 days after emergence. While allatectomy retards the normal development of flight capability, it also has the effect of slowing down the decline in flight performance characteristic of operated control locusts as they age.

The effects of allatectomy and ovariectomy on haemolymph proteins and lipid mobilization in Locusta

Journal of Insect Physiology, 1980
Abstract After ovariectomy the concentrations of diacylglycerol and protein in the haemolymph increase markedly. The increased diacylglycerol is associated with increased quantities of the ‘heparin-precipitable’ protein (lipoprotein A) that carries diacylglycerol in the blood of normal resting locusts. After the injection of adipokinetic hormone (AKH)

Effect of allatectomy on the growth of the male desert locust during adult development

Journal of Insect Physiology, 1971
Abstract The effect of allatectomy on the development of the adult male desert locust ( Schistocerca gregaria ) has been investigated. All operations were carried out at 4 days after adult emergence and allatectomized insects were compared with sham operated controls. Both sham operated and allatectomized insects showed some reaction to the operation
