Title : The sugar cane scale insect Aulacaspis tegalensis (Zehnt.) and its biological control in Mauritius and East Africa
Year of publication : 1973
Keywords : SUGARCANE; AULACASPIS TEGALENSIS; BIOLOGICAL CONTROL; PESTS; PEST CONTROL; BIOLOGICAL CONTROL ORGANISMS; INSECT PESTS; MSIRI STAFF; ENTO; SCALE INSECTS; MAURITIUS; AFRICA;
Citation : Williams, J. R.; Greathead, D. J.; The sugar cane scale insect Aulacaspis tegalensis (Zehnt.) and its biological control in Mauritius and East Africa; 1973
Abstract : The importance of A. tegalensis as a pest of sugarcane is described with particular reference to Mauritius and East Africa, where severe infestations have occurred in recent years. The factors that influence the insect's dispersal, distribution, and populations, are discussed. Cultural methods of control, including the use of resistant varieties, are of value but are not entirely effective or not always practicable. Work on biological control has involved studies of parasites and predators in the Mascarenes, Madagascar, East Africa, Indonesia and Australia and the known species and their distribution are tabulated. The introductions of parasites and predators that have been made in Mauritius and East Africa, and the resultsof these introductions as far as they can yet be assessed, are described.

Title : Incorporation of 32P in phosphate esters of the sugar plant and the effect of Si and Al on the distribution of these esters
Year of publication : 1973

Citation : Wong You Cheong, Y.; Chan, P. Y.; Incorporation of 32P in phosphate esters of the sugar plant and the effect of Si and Al on the distribution of these esters; 1973
Abstract : Good separation of phosphate esters labeled with P32 was obtained on paper-chromatography using the ascending technique in two dimensions at right angles. The pattern of phosphate esters in chromatographic resolution was similar for both the roots and leaves of sugarcane but there were differences in the relative proportions of the individual esters. Significant amounts of some esters, of which G-6-P constituted the main bulk, were labeled and indentified after short incubation periods of excised roots in the radioactive phosphate solution. Although Al pre-treatment at the level of 0.5mM Al2(SO4)3 stimulated labeled phosphate uptake, there was no effect on the extent of phosphorylation. With Si pre-treatment, however, a significant increase in the degree of phosphorylation was noted although no effect was obtained on labeled phosphate uptake.

Title : The effect of silicon on sugar cane growth in pure nutrient solution
Year of publication : 1973

Citation : Wong You Cheong, Y.; Heitz, A.; Deville, J.; The effect of silicon on sugar cane growth in pure nutrient solution; 1973
Abstract : Si, supplied as silicic acid significantly increased cane yields of two sugarcane varieties growing in pure nutrient solution and the sucrose yield of one variety. "Leaf freckling" symptoms only developed on those plants not receiving Si.

Citation : Julien, M. H. R.; The photoperiodic control of flowering in Saccharum; 1972
Abstract : Flowering in 2 clones of Saccharum spontaneum and 1 clone of S. robustum was found to be controlled by photoperiod. In the 2 S. spontaneum clones the earliest stages of development, induction and initiation of inflorescence axis primordium, required inter

Title : Rhizobium. I. Preliminary field studies on groundnuts (Arachis hypogea) and dwarf beans (Phaseolus vulgaris) in Mauritius
Year of publication : 1972

Citation : Pillay, A. R.; Mamet, J. R.; Rhizobium. I. Preliminary field studies on groundnuts (Arachis hypogea) and dwarf beans (Phaseolus vulgaris) in Mauritius; 1972
Abstract : Local strains of Rhizobium of groundnut are present in Mauritian soils. Observations at Medine, La Laura and Olivia showed the unfavourable effect of soil acidity on nodulation, and indicated a pH level (5.0) under which nodulation is severely reduced. Results of trials at Reduit showed that inoculation of Dwarf beans with foreign Rhizobium strain greatly increases yields.
