| Abstract: | Abstract The oviposition patterns of 6 larch cone flies, Strobilomyia spp., were surveyed in 1993 in Da Hinggan Mountains, northeastern China. The colonization of distinct phases of cone development and the selection of different sites to lay eggs allowed to distinguish 5 patterns of oviposition. Observations of the egg morphology and of the chorion architecture using scanning electron microscope lead to classify the examined cone fly eggs into 6 different types. Each type of egg was related to a given oviposition pattern. Among the 6 egg types, eggs of S. laricicola, S. melaniola and S. infrequens were identified with certainty. Although hypotheses were given, further experiments under controlled conditions are required to identify which of the 3 other egg types is associated to S. baicalensis, S. svenssoni and S. sanyangi, respectively. |
