DIURNAL TIMING OF OVIPOSITION OF EDOVUM-P UTTLERI (HYMENOPTERA, EULOPHIDAE), AN EGG PARASITE OF COLORADO POTATO BEETLE

Diurnal timing of oviposition of Edovum puttleri was studied in the la boratory (LD 17 : 7, t = 24-25). E. puttlery appears to escape oviposi tion during the dark phase (in the <<night>>) and just after beginning of the light phase (in the <<morning>>). The parasite prefers to infe st the eggs of Colorado potato beetle in the afternoons and in the eve nings. These results may be useful for mass rearing of E. puttleri.
