Morphometric changes and the hormonal activity of the corpus allatum in the adult male of the desert locust
(University of Nairobi, 1966-06)
There is a progressive increase in the volume of the corpus allatum of the adult male desert locust, Schistocerca gregaria, its cytoplasmic content, and the size of its nuclei which is correlated with progress towards ...
Growth, longevity, and the frequency of feeding of Glossina pallidipes Austen
(University of Nairobi, 1968-11)
Glossina pallidipes Austen have been successfully reared in the adult stage in the laboratory. The flies fed readily on the belly of guinea-pigs, and the latter did not seem to be worried by the attentions of the ...
The architecture of the accessory reproductive glands of the male desert locust: 1: types of glands and their secretions.
(University of Nairobi, 1969)
The accessory reproductive glands of the male desert locust were studied by histological, histochemical, and phase-contrast techniques. It was found that the characteristics of the glandular epithelium and their corresponding ...
Capture of the White (Square-Lipped) Rhinoceros Ceratotherium Simum Simum (Burchell) with the Use of Drug Immobilization Technique.
(University of Nairobi, 1962-09)
The capture of the white (square-lipped) rhinoceros ceratotherium simum simum (Burchell) by the drug immobilization method is described. Details are given of the drug doses and the reactions of the twelve animals immobilized. ...
The mechanics of bird migration
(University of Nairobi, 1969)
A theory is presented for calculating the relation between mechanical power required to fly and forward speed, for a bird flying horizontally. The significance of this for migration is explained, and quick methods are given ...

Influence of age and feeding on the success of mating in a tsetse fly species
(University of Nairobi, 1968-08)

Metabolic effects of the corpus allatum hormone in the desert locust, schistocerca gregaria
(University of Nairobi, 1965-09)
SOME thirty years ago, Wigglesworth1 first demonstrated that yolk deposition in insect oocytes is controlled by the corpus allatum hormone. Since then, the hormonal control of vitellogenesis has been complicated by some ...
The architecture of the accessory reproductive glands of the male desert locust: 2: Microtubular structures
(University of Nairobi, 1969)
Cytoplasmic microtubules are distributed widely in the mature accessory reproductive glands of the male desert locust. They are not concentrated in any particular region of the cytoplasm, but they appear to be closely ...
