Abstract The effect of allatectomy on the changes in activity of enzymes concerned with the conversion of dietary carbohydrate to lipid by the fat body during development has been investigated. The enzymes studied were phosphofructokinase, pyruvate kinase, malic enzyme, glucose-6-phosphate dehydrogenase isocitrate dehydrogenase, ATP citrate lyase ...

Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1994
Abstract Two types of artificial trimolters named A and B were induced by excising the corpora allata from the normal tetramolter of Bombyx mori at the periods before and after, respectively, the third molt. By using polyacrylamide gel electrophoresis, these trimolters were analysed for the banding patterns of haemolymph proteins at their final ...

In last instar larvae of Gryllus bimaculatus, the prothoracic glands as well as the ovary and the abdominal integument synthesize and release ecdysteroids. Ovariectomy of day (d) 1 penultimate instar larvae extended the last larval stadium from 8 to 12 days (at 27°C).

ABSTRACT. Host‐seeking behaviour in newly emerged Aedes aegypti (L.) females is not expressed immediately after adult eclosion but develops gradually over a period of approximately 3–4 days.

Canadian Journal of Zoology, 1976
Histological changes in the ovary during periods of yolk deposition suggest that differentiation of the follicular epithelium and oolemma is an essential prerequisite to the pinocytotic uptake of protein into the oocytes. Before vitellogenesis, intercellular spaces form between adjacent follicle cells, and a brush border appears along the oocyte ...

A study was made on the effects of allatectomy, brain cauterization and juvenoid treatment on the activities and distribution of protease, amylase, lipase, trypsin and chymotrypsin in various regions of the gut of the adult mole-cricket, Gryllotalpa gryllotalpa (Curtis). Allatectomy resulted in a significant reduction in the amount of protease, lipase,

Acta biologica Hungarica, 1988
Light and electron microscopic investigations were carried out on the fourth day imago of the house cricket, Acheta domestica L. treated with benserazid, or allatectomized. Introduction of benserazid (daily on the 1st, 2nd and 3rd days of imaginal life in 0.1 mg/g) failed to influence the development of the oocytes.

Journal of Insect Physiology, 1967
Sexual behaviour of males, oocyte development in females, and colour changes of both sexes of Schistocerca gregaria following various treatments carried out on adult locusts were studied. Surgical treatments included allatectomy, severance of the nervi allato-suboesophagealis, severance of the nervi corporum allatorum, and complete denervation of the ...
