摘要：

Metaseiulus occidentalis females from the carbaryl-organophosphate-sulfur resistant strain (COS) lived longer (25.3 days versus 19.7 days), had a higher total fecundity (43.8 eggs female-1 versus 33.6 eggs female-1) and a higher daily fecundity rate (2.4 eggs female-1 day-1 versus 2.0 eggs female-1 day-1), and exhibited a higher intrinsic rate of increase (0.243 individuals female-1 day-1 versus 0.182 individuals female-1 day-1) and shorter generation time (13.9 days versus 17.0 days), at 24-28°C, 47-56%rh under continuous fluorescent light, when reared on a diet of 0-48-h-old eggs rather than a diet of mixed actives of Tetranychus pacificus McGregor on bean leaf disks. The sexratio of the progeny was female-biased for both diets, 2.1 females to 1 male for M. occidentalis reared on eggs and 2.0:1 ♀:♂ for M. occidentalis reared on mixed actives, suggesting that diet influences sex-ratio in some unknown way. There was no significant difference in oviposition rates for repeatedly-mated and once-mated M. occidentalis females reared on a diet of younger (0-24-h old) eggs compared to a diet of older (72-96-h old) eggs of T. pacificus. The COS strain of M. occidentalis exhibited life-table parameters comparable to the other strains reported in the literature, suggesting that the reproductive attributes of this acarine predator were not reduced as a result of artificial laboratory selection. Diet, a biotic factor, produced substantial differences in life-table parameters, suggesting that this factor can influence conclusions regarding the potential efficacy of biological control agents. © 1990 Elsevier Science Publishers B.V.
