For all experiments, the moths were reared in the laboratory on an artificial diet (Greene et al. 1976) until reaching the adult stage. After the start of oviposition in the laboratory (age 3 d), the moths were released into the cages at the beginning of the scotophase at a density of 100 pairs (100 males and 100 females) per cage and maintained for 3 d for egg-deposition on the plants. All detected egg masses were removed 72 h after the release of the moths and taken to the laboratory, where the number of eggs and egg position on the plant (bottom, middle, and upper sector of the canopy) were evaluated. Canopy sectors were identified by measuring plants of each species and equally dividing them into 3 parts. Therefore, the size of each part is different for each host species. Even though some of the host species might be small at the time of oviposition, canopy division **data** is able to provide further insight into this biological parameter. Understanding the oviposition preference for each part of the plant canopy is important for growers to help them find eggs in the field. This is crucial to forecast pest outbreaks as well as to devise necessary biological control strategies such as the release of egg parasitoids.
