Oriental fruit moth, Grapholita molesta (Busck), is a worldwide pest and is the dominant pest of rosaceous plants in northern China. Little is known, however, about the influence of abiotic factors on the daily life history events of this economically important pest, so here we evaluated the effect of different photoperiods (L:D) (0:24; 2:22; 4:20; 6:18; 8:16; 10:14; 12:12; 14:10; 15:9 (control]; 16:8; 18:6; 20:4; 22:2; and 24:0 h) and light intensities (50, 100, 200, 300, 400, and 500 lux) on the mating behavior and reproduction of oriental fruit moth. We found that oriental fruit moth adults with an 8, 9, or 10 h scotophase showed considerably more courtship behavior than those in other photoperiod treatments. Meanwhile, male fanning and male 'crawling in a circle' behaviors significantly decreased with increasing light intensity. Neither female or male oriental fruit moth longevity nor the egg hatch rate were influenced by photoperiod (P= 0.146; 0.271; 0.107) or light intensity (P= 0.268; 0.08; 0.123). In both photoperiod and light intensity treatments (P< 0.05), the number of eggs laid daily by females was significantly influenced by female age, decreasing with greater age. Female oriental fruit moth lifetime fecundity was influenced by photoperiod, with the 9, 10, 16, 18, and 22 h scotophase periods having higher fecundity than other treatments. Meanwhile, fecundity decreased with increasing light intensity.
