Attention is given to the higher recapture rates of Q. gigas males observed in SW and NE directions, points of the area close to Eucalyptus trees. In general, lower recapture rates were observed for the other distances and directions. Even in a lower rapture rate, it was possible to recapture green-marked Q. gigas at 1,000 m far from the release point ( Table 2 ; Fig. 4A ). The recapture rates of Q. gigas females, like those of males, were, in general, higher at 100 m points far from the released points (SW = 3.77%; WNW = 2.66%; NW = 4.2%; N = 4.01%; NE = 4.63%) and at 250 m at SW and NE directions (4.77 and 1.23%, respectively). In here, again, we point out that SW and NE directions that presented higher recapture rates were the closest to Eucalyptus plants. For the other directions and distances, recapture rates were generally smaller, but, as for males, Q. gigas females could also be recaptured at 1,000 m far from the release point ( Table 2 ; Fig. 4B ). Time Course Recapture of Quesada gigas A higher recapture rate (2.14%) of green-marked Q. gigas was observed at 2 d after release, and recaptures were observed up until 20 d after release ( Fig. 5 ). No green-marked Q. gigas was recaptured after the 20th day after release. With this result, we estimated the maximum adult longevity in the field in approximately 49 d because emergence started 29 d (19 September 2017) before the first capture, marking, and release procedure (17 October 2017). Mating Behavior and Oviposition of Quesada gigas The number and duration of mating and oviposition periods were recorded during the process of capture and recapture of adults in the area. In total, 362 couples were observed mating between 5 October and 30 October 2017. The mating period was 41.6 ± 0.43 min. Seven hundred ovipositions were observed between 17 October and 31 October 2017, and the period of a single oviposition bout was 30 ± 0.20 min. It was also observed that males and females that had previously mated were attracted again to the sound trap. The number of mated individuals reattracted to the sound trap was 56 males and 104 females, representing 15.46% and 28.72% of the 362 matings observed. The recapture of individuals that had previously mated occurred at all recapture points, showing that even those insects that dispersed to long distances from the release point, e.g., 1,000 m, may mate after long dispersion. Furthermore, it was observed that mated individuals attracted to the sound trap mated again. Twenty-four males and three females of Q. gigas mated with partners different from those of the first mating.
