... antitrust: a body of laws making illegal various actions that have the effect of changing prices, allocating sales, or otherwise restraining trade. competition: the interaction between populations in which there is mutual inhibition of each other's growth due to the sharing of common resource(s)

From page 450...
... The fact that a pest population has a verified level and frequency of resistance does not necessarily mean that there has been a loss of economic efficacy, or that use of the pesticide should be discontinued. Conversely, it is possible to have a loss of economic efficacy without resistance (i.e., the introduction of a more effective pesticide, cultivar, or cultural practice; the microbial degradation of the pesticide before it reaches the pest)

From page 451...
... Laboratory documentation of resistance, however, does not necessarily indicate a current or impending loss of economic efficacy in the field. selection: changes in the genetic composition of populations resulting from the differential survival or reproduction of specific genotypes.

... additive genetic variance: the proportion of the phenotypic variance that is due to cumulative expression of alleles of the same gene or different genes that are acting independently in the determination of the value of a continuously distributed character, e.g., height. nonadditive genetic variance: the proportion of the phenotypic variance that is due to cumulative expression of alleles of the same gene or different genes that are not independent in their determination of the phenotype, e.g., the contributions of dominance and epistasis.
