Body mass and wing geometric morphology of the codling moth (Lepidoptera: Tortricidae) according to sex, location and host plant in the region of Maule, Chile
Codling moth, Cydia pomonella (L.) (Lepidoptera: Tortricidae), is the key pest of apple and walnut production worldwide. Among other variables, successful management of this pest is dependent on adult dispersal at the local scale. Body mass and wing geometric morphology were evaluated on female and...

Body mass and wing geometric morphology were evaluated on female and male codling moth adults collected from apple and walnut trees in three localities of the Region of Maule. Codling moth adults were obtained by rearing diapausing larvae collected from the field. Newly emerged adults were killed, and the total dry weight, thorax weight and abdomen weight were calculated.

In addition, wing length, area, loading, and aspect ratio were evaluated. As previously reported, females showed larger thorax, abdomen and total body mass, with longer, larger, and wider wings than males but with similar wing loading as males.

Codling moth, Cydia pomonella (L.) (Lepidoptera: Tortricidae), is the key pest of apple and walnut production worldwide. Among other variables, successful management of this pest is dependent on adult dispersal at the local scale. Body mass and wing geometric morphology were evaluated on female and male codling moth adults collected from apple and walnut trees in three localities of the Region of Maule. Codling moth adults were obtained by rearing diapausing larvae collected from the field. Newly emerged adults were killed, and the total dry weight, thorax weight and abdomen weight were calculated. The wings were cleared and mounted for morphometric analyses: 15 and 11 characteristics of the fore and hind wings, respectively, were measured, including the meeting points of the veins and attaching points to the margins. In addition, wing length, area, loading, and aspect ratio were evaluated.
