ii) Higher costs involved in spraying. ; There are primary factors that determine biotic potential: an organism's rate of reproduction and its litter size — the number of offspring produced at one birth. Populations rarely reproduce at their biotic potential because of limiting factors such as disease, predation, and restricted food resources. 1.

BREEDING FOR INSECT RESISTANCE The necessity for resistance breeding are. Certain factors like thermal affect is changing the status of pest by suppressing or stimulating genetic potential, rate of fecundity and mortality and range of hosts [21, 46]. Chapman relates to a "vital index": Vital Index = (number of births/number of deaths)*100 1. optimum environmental conditions. iv) Building up of resistance - E.g. Biotic potential is the ability of a population of living species to increase under ideal environmental conditions – sufficient food supply, no predators, and a lack of disease. Consider the Panda, what might we mean by Biotic potential and Environmental resistance in the case of a panda population?

Pyrethroid Mechanism of insect resistance : Painter (1951) 1. Carrying capacity refers to the maximum number of individuals of a species an ecosystem can support within the natural resource limit, without being degraded due to the deterioration or damage. Biotic potential, the maximum reproductive capacity of an organism under optimum environmental conditions.It is often expressed as a proportional or percentage increase per year, as in the statement “The human population increased by 3 percent last year.” It can also be expressed as the time it takes for a population to double in size (doubling time). species has its highest birthrate and lowest mortality rate.
