Figure 1 in Water quality assessment of the Demetrio stream: an affluent of the Gravataí River in the South of Brazil
Figure 1. Satellite view of the area and water sampling points of Demétrio stream: point 1 source, point 2 and point 3, upstream near the area with the highest urban density and from the downstream near the meeting point of the Demétrio stream with the Gravataí River.

Fig. 3 in Tools and Methods to Assess Field Performance Locomotion activity meter for quality assessment of mass-reared sterile male moths (Lepidoptera)
Fig. 3. Mean activity counts for before and afer pheromone exposure (lef), and the mean afer/before activity ratio (right), for un-irradiated (0 Gy = −) and irradiated (300 Gy = +) Epiphyas postvittana males. Error bars are 95% confidence limits for each mean. An afer/before ratio of 1 (marked) indicates an equal level of activity before and afer pheromone exposure.
Fig. 2 in Tools and Methods to Assess Field Performance Locomotion activity meter for quality assessment of mass-reared sterile male moths (Lepidoptera)
Fig. 2. Measured activity of male Epiphyas postvittana as summed counts at 30 s intervals in a locomotor activity monitor, before and afer pheromone stimulus of irradiated and non-irradiated moths.
Fig. 1 in Tools and Methods to Assess Field Performance Locomotion activity meter for quality assessment of mass-reared sterile male moths (Lepidoptera)
Fig. 1. An illustration of the modified Locomotion Activity Monitor set-up used for the bioassays in this study. Synthetic pheromone was puffed (2 s) from upwind to stimulate LBAM males into wing fanning. Each time a male moved through the beam array it was counted as 1 observation. Comparisons were made between pre-pheromone exposure activity and post-pheromone exposure activity for each treatment.
Fig. 4 in Tools and Methods to Assess Field Performance Locomotion activity meter for quality assessment of mass-reared sterile male moths (Lepidoptera)
Fig. 4. Mean activity counts for before and afer pheromone exposure (lef), and the mean afer/before activity ratio (right), un-irradiated (0 Gy) and irradiated (300 Gy) Epiphyas postvittana males exposed to 1 of 4 levels of temperature shock (0, 1, 2, 4 h at 30 °C). Error bars are 95% confidence limits for each mean. An afer/before ratio of 1 (marked) indicates an equal level of activity before and afer pheromone exposure.
