Abstract
In laboratory experiments on Diglyphus begini reared on Liriomyza trifolii larvae on chrysanthemum, both male mating success and male progeny production were positively correlated with male wasp size only when male accessibility to females was good. No correlation was made if male accessibility was reduced. Progeny production by female wasps was positively correlated with female size. Females gained more reproductive success with increasing body size than did males if accessibility was limited, confirming Charnov's sex allocation model [Charnov, E. L. The theory of sex allocation. NJ, USA; Princeton University Press, 1982.] under these conditions. Host density had no influence on the effects
