Global temperature may increase by up to 4.8°C until 2100, according to predictions from the Fifth Assessment Report (AR5) ofthe Intergovernmental Pane1on Climate Change (IPCC, 2013). According to Calzadilla et al. (2013), global agricultural production is expected to decrease by 0.5% in the medium and 2.3% in the long termo Besides that, the distribution of harvested land is expected to change, implying modifications on production and intemational trade patterns (Calzadilla et al., 2013). In Brazil, global climatic changes are supposed to influence agriculture, which is responsible for 22% ofthe Brazilian gross national product (CEPEA, 2013),Adaptation ofproduction systems and mitigation of greenhouse gas emissionsare the main challenges imposed by global climate changes to agriculture. |

Aphids are insects that attack crops and cause damage directly, by consuming the sap of plants, and indirectly,by vectoring microorganisms that can cause diseases. Cereal crops are hosts for many aphid species, includingRhopalosiphumpadi(an economically important aphid species). Recording and classifying aphids are necessaryfor evaluating and predicting crop damage. Thus, serving as a basis for decision making on the utilization ofcontrolmeasures.Itcanalsobeusefultoevaluateplantresistancetoaphids.Traditionally,therecordingprocessis manual and depends on magnification and well-trained staff. The manual counting is also a time-consumingprocess and susceptible to errors. With this in mind, this paper presents a method and software to automate thecounting and classification ofRhopalosiphum padiusing image processing, computer vision, and machinelearningmethods.Thetextalsopresentsacomparisonofmanuallycountsfromexpertsandvaluesobtainedwiththe software, considering 40 samples. The results showed strong positive correlation in counting and classifi-cation(rs=0.92579)and measurement (r=0.9799).Concluding, thesoftware provedtobe reliableandusefulto aphid population monitoring studies. |
