The spittlebug, Mahanarva spectabilis, causes two types of injury to forage crops. The nymphs constantly suck the sap, causing the whole plant to yellow. The other type of damage is caused by the adult spittlebug, which feeds on shoot, leaves and sprouts, causing a phytotoxic response that varies among grass species used in pastures. Given the impact of this insect on forage crops, it is important to understand how global changes may influence its ecology and thus assess whether future i ...

Spittlebug, Mahanarva spectabilis (Hemiptera: Cercopidae) is capable to cause drastic losses in production and quality of pastures established with grasses. Currently, the use a grass resistant cultivar, to be obtained by means of constitutive antibiosis, is the best spittlebug controlling method. However, the time required for releasing a cultivar after detecting a spittlebug-resistant strain is relatively long. Allied to this, one should take into consideration that the adaptations of

Epidemics of Diseases whose Pathogens are Transmitted by Insects (EDTIs) are frequent and impactful in the areas of human, animal and plant health. Due to its complexity, understanding the dynamics of EDTIs requires the accumulation of epidemiological data from monitoring networks and the use of models that establish the chain of relations between their components and calculate, under environmental oscillations, the rate and progress of the biological processes. This project proposes to develop
