Abstract

Diel activity patterns of leafminer, Liriomyza trifoliiand its parasitoids Opius dissitusand Diglyphusspp. were evaluated by using yellow sticky traps in bean (Phaseolus vulgaris ‘Opus’) fields. Densities of L. trifoliiwere found more abundant from 0800 to 1000 hours than any other time within the day during fall 2010, but did not show any clear pattern of diel abundance in spring 2011. Parasitoid O. dissituswas found abundant from 1001 to 1200 hours during spring 2011, however no significant diel density pattern was observed in fall 2010. Diglyphus spp. was more abundant during 1001 to 1200 hours and 1201 to 1400 hours than any other time in fall 2010 and spring 2011, respectively.
