control (ABC) and its predicted usefulness. Biological pest control is the use of living organisms to control pests such as insects‚ mites‚ weeds and plant diseases (Wiki‚ 2013). Relying on natural mechanisms like predation‚ herbivory‚ pathogens and parasitism‚ bio control agents are quite often the natural enemy of a pest; parasites and predators are used to reduce insect and other animal pests while herbivores are used to control weeds (Wiki‚ 2013). Biologically based pest management typically involves

Practical guide to detection and identification of Phytophthora Leaf blight A number of Phytophthora species cause leaf blight. These include: P. infestans on potato and tomato; P. palmivora on a large number of tropical fruit species including rubber‚ durian and macadamia; and P. colocasiae on taro. These blights on leaves are first seen as small flecks but within 3-5 days they expand to produce large lesions. Initially‚ infected tissue is water soaked but becomes necrotic (brown or black) in

However‚ interactions between different species may take different forms‚ such as commensalism‚ parasitism‚ amensalism etc. Competition often results in reduced growth and/or lower seed production of one or both individuals or species when compared to the yield of either when grown alone.

Genetics: the science of heredity that includes the study of what genes are‚ how they carry info‚ how they are replicated and passed to subsequent generations of cells or passed between organisms‚ and how the expression of their info within an organism determines the particular characteristics of that organism. Genome: the cell’s genetic information that includes it’s plasmids and chromosome. Chromosomes: structures containing DNA that physically carry hereditary info‚ contain the genes Genes:

For lack of time and for the sake of convenience we generalise and crush our human facts into the packages within the steel trunks that hold our travellers’ reports. Our knowledge of our own countrymen and our feelings about them have slowly and unconsciously grown out of innumerable facts which are full of contradictions
