E. J. LeRoux. 1954. Effects of various levels of nitrogen, phosphorus, and potassium in nutrient solution, on the fecundity of the two-spotted spider mite, Tetranychus bimaculatus Harvey (Acarina: Tetranychidae) reared on cucumber. Canadian Journal of Agricultural Science 34 (2): 145-151.

Keywords: studies were conducted on the various levels of nitrogen, phosphorous and potassium on the fecundity of the two-spotted mite feeding on cucumber in the greenhouse using nutrient solutions, populations of spider mite doubled when N level was doubled, significant population increases were also ascribed to interactions between increased N and K as well as N and P, fertilizer effects
